In the metal construction, quality and safety are not optional. Since 2014, all manufacturers of steel structures in Europe have had to comply with the Standard EN 1090, This is an essential requirement in order to be able to market your products within the European Union. In this article we explain what is EN-1090 certification, why it is mandatory, y what are the benefits to both manufacturers and customers.

What is EN-1090?

The EN 1090 is a European standard that regulates the manufacture and erection of steel and aluminium metal structures. Its main objective is to ensure that structural elements comply with the requirements of the levels of quality, strength and safety required in the European market.

This standard is divided into three main parts:

1. EN 1090-1: Requirements for the conformity assessment of structural components (mandatory for CE marking).
2. EN 1090-2: Technical requirements for execution for steel structures.
3. EN 1090-3: Technical requirements for execution for aluminium structures.

Why is it compulsory?

From the 1 July 2014, the EN 1090-1 is obligatory compliance for all manufacturers wishing to CE marking in its structural metal products.
Without this marking, it is not permitted marketing or installing metal structures in the European Economic Area.

This means that only certified companies can manufacture and erect safe and legal metal structures for use in industrial buildings, halls, walkways, canopies or any other type of metal construction.

What does it mean to be EN-1090 certified?

To obtain this certification, the manufacturer must demonstrate that:

• It has a factory production control (FPC) system to ensure traceability and quality of materials and processes.
• Welding personnel are qualified according to standards such as ISO 9606 or ISO 14731.
• Welding procedures (WPS) are approved and documented.
• A systematic inspection and control of production.
• The company is supervised by a notified body which audits compliance.

At INNOVA we comply with all these requirements, which allows us to manufacture certified and safe metal structures, ensuring the highest quality and compliance with European standards.

Imagine a house built with earth, wood and lime, a shelter that breathes, that regulates its temperature without the need to turn on an air conditioner, and which also alerts you when it needs to be ventilated or when it detects moisture on a wall.. It's not science fiction, it's the new frontier of architecture, known as the intelligent bio-constructionan approach that fuses natural materials with state-of-the-art sensors to take care of both the building and the people who live in it. This type of construction represents a logical and necessary evolution of sustainable architecture. It is based on returning to age-old techniques, such as the use of mud or straw, but adding something that we didn't have before, such as the technology that observes, interprets and helps us to make decisions. The result is more efficient and also more humane.

Back to the natural without renouncing the intelligent

For years, bio-construction has been identified with rural houses, adobe domes or low environmental impact projects far from cities. But this is changing. Today, with the help of the Internet of Things (IoT), these constructions can be as sophisticated as any high-tech building.They do not seek to dominate the environment, but to coexist with it.

The IoT sensors allow homes to "listen" to what is going on inside them and their structure. They can detect changes in humidity, measure air quality, record temperatures and send you an alert to your mobile phone if something is wrong. And they do it almost invisibly, without altering the aesthetics or the soul of a home made of natural materials. Because if there is one thing that defines this trend, it is balance, technology to be useful, but not invasive. That adds, without detracting from authenticity.

What can a house built of straw tell us?

More than you might think. In a concrete building, detecting a leak or a lack of ventilation can be a matter of luck. In a bio-built home, such problems can lead to serious deterioration if not detected in time. This is where sensors come into play.

• Moisture sensor in wallsEssential in houses made of mud, straw or wood. They detect possible condensation or leaks, long before mould appears or the structure is damaged. They are like an early warning system that allows action to be taken before it is too late.

• CO₂ and Indoor Air Quality MetersAlthough natural materials do not emit toxic substances, this does not mean that the indoor air is always healthy. A sensor may, for example, indicate that there is too much CO₂ in a closed room and suggest opening a window.

• Smart thermometersIn a well-oriented and insulated house, a heating or cooling system is often not necessary. But having sensors that inform you of how each zone of the home behaves thermally is useful for adjusting blinds, windows or mobile elements. In the long term, it helps to optimise comfort and reduce consumption.

• Accelerometers or structural motion sensorsThey warn of micro-cracks, displacements or differential settlement of the ground. You don't have to wait for a wall to crack to know that something is wrong.
  And all this can be controlled from a simple app on your mobile phone. You don't need to be an engineer. The idea is that the user receives clear and practical information: "ventilate the room", "there is humidity on the north wall", "the temperature is optimal, it is not necessary to turn on the cooker".. It's as if the house is talking to you..., but without raising its voice.

Technology at the service of life, not the other way around

One of the great fears when talking about "smart homes" is to fall into over-automation. No one wants to live in a kind of laboratory, but in smart bio-construction, the approach is different, since it is not about delegating everything to technology, but about using it as a silent ally..

The sensors are small, unobtrusive and many are powered by long-life batteries or solar systems. They are integrated during construction or placed in strategic points without cables, without building work, without breaking the aesthetics. And, above all, they make house maintenance much easier and more economical. Because we know how each material, each wall and each corner behaves, it is possible to anticipate problems, instead of solving them when it is already too late.

A house that takes care of itself... and that takes care of you.

Living in a house built with mud, straw or wood is not only an aesthetic or ecological choice. It is also a way of seeking real welfare because it has less toxins, better insulation and more contact with nature. And if that house, in addition, helps to maintain these values over time, the benefit is double.

Some of the most obvious results of applying technology to bio-construction are:

• Increased durability: Detecting problems before they become serious extends the life of natural materials.
• Better inner healthReal-time data lets you know if the air you breathe is clean or if you need to refresh the environment.
• Energy savingBy understanding how your house behaves thermally, you can optimise its use without overspending.
• Reduced environmental impactBecause the less you intervene in your home, the less resources you consume and the less waste you generate.

And the best thing is that you don't need a complex home automation system, just well thought-out sensors and a design that integrates them from the start.

Case studies: When theory becomes home

In Spain, there are already bioclimatic dwellings that integrate low-cost sensors to monitor humidity in mud walls, temperature in green roofs or even CO₂ levels in rooms without cross-ventilation. In Galicia, some architects have started to use sensors to study the thermal behaviour of straw bale walls, adapting their designs according to the data collected. In France and Germany, many ecologically refurbished rural houses include sensors connected to their biomass cookers to fine-tune their use. What is most interesting about these examples is that they are not laboratory prototypesbut real homes, inhabited by real people, confirming that the future of construction lies in learning to measure what cannot be seen... in order to improve what can be felt.

For intelligent bio-construction to become a common practice, we need more than just technology, we need to courageous, educated and change-sensitive professionals. Architects who integrate sensors from the design stage, engineers who are as excited about calculating a structure as they are about interior comfort, and technicians who understand that not everything natural is at odds with innovation.

At Ingea Innova we are committed to Sustainable Innovation. For example, our roof equipped with photovoltaic system and our Carbon Footprint reduction programme are examples of smart solutions that integrate perfectly with this philosophy. Visit our section on About us to get to know us and our work.

The new role of the architect and the engineer

Because, in the end, building with mud and sensors is not a contradiction. It is a statement of principle. A way of saying: We do want comfort, but not at the expense of the planet. We do want technology, but at the service of the human. In short, the Intelligent bio-construction is neither a fad nor a utopia. It is the logical step of a society that has understood that we cannot go on building as if resources were infinite. It is the answer to those seeking quality of life, environmental health and real efficiency. And, above all, it is a path open to new ways of inhabiting the world, more conscious, more connected and, yes, much more humane too.

Not so long ago, asbestos was considered an irreplaceable element, the star material on many construction sites. This element was found in roofs, pipes, roofing, downpipes, floors and pavements, tanks, fireproof materials, electrical installations, sealants and joints, vehicles and industrial installations, storage elements and, above all, in the widest variety of insulation, both thermal and acoustic. Today, due to its hazardous nature, its presence is a public health problem that requires specialised solutions such as the professional service from Innova for asbestos removalessential for safely dispose of this material and in accordance with the current regulations.

The reasons given for this generous use in innumerable sections of any building were, above all, their fire resistance and low costThese factors made it a common resource in construction and industry. However, time has shown that this "miracle material" concealed a silent enemy, highly harmful to health of the workers and any person who was close to her.

Although in Spain its use is prohibited since more than two decadesThe EU has been involved in the construction of the new buildings, in particular all those built before 2002, thousands of buildings, installations and structures, still retain elements with asbestos. And that represents a risknot always immediate, but real.

In this article we explain why asbestos is so dangerous, how to identify it y what to do if you believe your property or business could be affected.

A glimpse into the past: what is asbestos and why was it used so much?

The asbestos (or asbestos) is a natural mineral made up of microscopic fibres. It was very popular between the 1950s and 1990s because of its qualities: does not burn, resists chemicals, isolate heat very well and, moreover, it is cheap. It was used in more than 3,000 different products, from fibre cement boards to thermal coatings to fire protection panels. A construction star that kept a sinister shadow among its fibres.

So what makes it such a serious problem? The answer lies in those fibres of which it is composed. When asbestos deteriorates or is handled without protection, releases invisible fibres that remain suspended in the air. When inhaled, they can accumulate in the lungs and cause very serious diseases.

A threat you can't see... but you can feel it

One of the most worrying aspects of asbestos is that no immediate symptoms. This means that the associated diseases often appear decades after the exhibition. And, when they manifest themselves, they are often already at an advanced stage and therefore, difficult to deal with. Some of the best known pathologies are:

• Asbestosischronic pulmonary fibrosis, caused by a build-up of fibres in the lungs. It causes shortness of breath, fatigue and may worsen over the years.
• Mesotheliomaasbestos cancer: a very aggressive type of cancer that affects the pleura (the membrane that surrounds the lungs). It is directly linked to contact with asbestos.
• Lung canceralso related to inhalation of fibres, especially in workers with prolonged exposure.
• Pleural plaquesThese are the most benign lesions, but indicate that exposure has occurred.

And the most alarming thing is this: there is no "safe" dose of asbestos exposure. Under certain conditions, a single exposure could be enough to cause any of the listed diseases. This is why, exercise caution is indispensable, so it was inevitable that it would be banned.

How do you know if a building has asbestos?

It is not uncommon for homeowners to be unaware of whether their property contains asbestos-containing materials. In Spain, any construction prior to 2002 could house itespecially if it has not been refurbished. The places where it is usually present are:

• Fibre cement roofs (the famous "fibre cement roofs").uralitas")
• Downpipes water and drains
• Deposits old
• Insulation thermal and acoustic
• False ceilings or vinyl flooring with black base

It is not always easy to recognise with the naked eye. The only sure way to confirm it is by a laboratory analysis carried out by a specialised company. If there are suspicions, the most sensible thing to do is not to touch anything and contact professionals to ensure its composition and remove asbestos.

What the law in Spain says about asbestos

As already mentioned, since 2002, the use of asbestos has been totally banned in our country. This includes its manufacture, marketing and installation. However, the regulation also establishes a series of clear obligations for those who own or manage properties where this material can be found as part of their structure and components.

• Asbestos may not be handled without authorisation or specific protection..
• Any withdrawal must be carried out by companies registered in the RERA (Register of Companies at Risk from Asbestos).
• Before taking action, it is mandatory to submit a WORK PLAN to the labour authority.
• Protective measures must be taken for workers, neighbours and the environment.

In addition, the latest European updates have further tightened exposure limits and measurement protocols. The tolerance is zero.

What should owners and companies do when removing asbestos?

If you have premises, buildings or installations that could contain asbestos, you are not alone. In fact, it is a very common situation. But it is also important to know that there are safe and effective solutions. Here are some key steps:

• Make a technical assessment. Do not act without knowing. A specialised company can check your property and carry out the necessary tests.
• Avoid intervening on your own. Drilling, breaking or cutting suspect materials is extremely dangerous.
• Get informed and well-informed. Each case is different, and the solutions must be different too.
• Rely on an authorised company. Only they can remove asbestos legally and safely.

Why having a specialist company makes all the difference

Removing asbestos is not just any job. It requires experience, training and, above all, a protocol rigorous. An approved company is responsible for:

• Carrying out the identification tests necessary
• Design and present the work plan to the authorities.
• Establish a secure perimeter during the intervention
• Decontaminate, withdraw y transport waste with authorised means
• Issue the certificates that demonstrate the elimination of the risk

At InnovaWe have been working for years in the field of asbestos removal on roofs, industrial facilities and buildings of all kinds. We know how to do this quickly, safely and in compliance with all legal requirements. Our priority is that you don't have to worry about anything.

Prevention is the best tool

Asbestos represents a real risk, but it is also manageable. Knowing the problem, acting responsibly and relying on qualified professionals is the key. It is not only a matter of complying with the law, but also of protecting the health of those who live, work or pass through this space..

If you suspect that your property may contain asbestos or if you need technical advice, at Innova we can help you. Because you don't have to wait until there is a problem to take action.

It is visible to the naked eye, on any walk through the cities, how the metallic structures have revolutionised the world of modern construction. The fundamental reasons for this transformation are its versatility, strength and efficiency.

From the skyscrapers that shape city skylines to the logistics warehouses that move the pulse of industry, the use of metal as the main structural element has established itself as one of the most important smarter choicesfor both large-scale and smaller-scale projects.

It is worth asking, in any case, whether we really know what types of metal structures exist and in what contexts they are used. The aim of this article is to explore the main metallic structural typologies, their advantages and the scenarios in which they offer the best performance, taking as a reference the experience of leading companies in the sector, such as Ingea Innovawhere we have been providing efficient and customised solutions in this area for years.

1. Cross-linked structures (lightness and efficiency)

Also known as triangulated structures or metal trusses, they are formed by bars joined in the form of triangles, which allows the loads to be distributed efficiently..

It is a geometric design whose triangulation ensures stability, minimises the risk of deformation and reduces the overall structural weight.

They are especially useful when large spans need to be covered without intermediate supports, as in:

• Industrial buildings
• Pedestrian or vehicular bridges
• Sports roofs
• Hangars and logistics warehouses

This type of structure stands out for its low own weight in relation to the load-bearing capacity they can withstandThis reduces the need for heavy foundations. In addition, it allows for modular construction, facilitating transport and assembly.

In cases such as those developed by Ingea Innova in logistics complexes, the reticulated solution has been key to reducing execution times and guaranteeing total accessibility.without pillars interrupting the usable space. This type of structure is also common in pavilion roofs, where the absence of intermediate columns improves the functionality of the enclosure.

2. Metal portal frames: robustness for modular buildings

This is one of the most common structural systems in steel construction. It consists of rigid frames forming the load-bearing structure of rectangular buildingsusually with pitched roofs. This system is characterised by combining structural simplicity with excellent resistance to vertical and horizontal loads.

Its main fields of application include:

• Retail-type commercial premises
• Industrial and agricultural buildings
• Logistics centres
• Mechanical workshops

One of its major advantages is the modularitywhich allows the structure to be easily expanded or modified. Added to this is a remarkable speed of executionideal for sites that need fast delivery without sacrificing quality.

In addition, the gantries allow a good use of interior spaceThis is especially valued in industrial projects. Ingea Innova has implemented double-height porticoes in mixed buildings (warehouse + offices), integrating natural lighting solutions using translucent panels and passive ventilation systems.

3. Three-dimensional spatial frameworks: solutions for the large scale

When there is a need to build spaces without visual or structural restrictions, such as stadiums, auditoriums or transport stations, the three-dimensional spatial structures come into play. They are systems composed of metal nodes and rods that form a three-dimensional framework of high rigidity and strength.

Its main benefits are:

• High capacity to cover large areas without interior columns
• Structural stability in all directions
• Modern aesthetics and visual impact

This type of solution requires a more complex detailed engineering and precise planning during the construction phase. In these cases, the design phase is particularly important, as small errors can have a significant impact on the installation.

Ingea Innova has shown that, thanks to the use of BIM modelling tools and load simulation in a 3D environmentIn this way, it is possible to anticipate any incident and optimise both manufacturing and on-site assembly.

4. Lattice structures: tradition with high performance

The metal lattices are structures composed of cords (upper and lower) and diagonals forming a kind of light but strong skeleton. Their behaviour under horizontal and vertical loads makes them ideal for specific applications such as:

• Rail and road bridges
• Electrical transmission or telecommunication towers
• Cranes and heavy machinery
• Modular footbridges or viaducts

What makes these structures stand out is their excellent weight/load capacity ratioand the possibility of be manufactured in tranches which are then assembled on site. This aspect is key on sites that are difficult to access or where assembly must be carried out under limited conditions.

While some firms continue to use traditional methods, companies such as Ingea Innova have incorporated robotic welding technology, non-destructive quality control and hot-dip galvanising to ensure durability and strengtheven in saline or high humidity environments.

5. Mixed structures: the best of two worlds

These structures combine steel with concrete or other materialsThe best of each can be used. For example, metal columns can be used with reinforced concrete slabs, or steel beams with composite slabs. In this way, an ideal synergy is achieved to optimise the design in both structural and functional terms.

Where do they apply?

• Office buildings and educational establishments
• Hospitals and health centres
• Multi-storey car parks
• Rehabilitation and structural reinforcement

These structures offer great architectural flexibilityThe new, cost-optimised, high-speed, high-speed systems are particularly useful on urban construction sites where construction rates are demanding and margins for manoeuvre are tight.

Thanks to advanced engineering, firms such as Ingea Innova have taken this type of solutions to the next level, applying them even in integral renovation projects where the aim is to to lighten the structural load without compromising the original load-bearing capacity.

6. Self-supporting towers and structures: vertical stability

In fields such as wind energy, public lighting or telecommunications, the following are required free-standing vertical structuressuch as metal towers or masts, designed to withstand wind loads, self-weight and extreme conditions. Here, the lightness of the steel and its ability to withstand bending stresses is crucial.

Typical applications:

• Telecommunication towers
• Lighting masts
• Wind towers
• Supports for billboards and urban signage

These structures, although less visible to the general public, require a high specialisation. Knowledge of anchoring, structural dynamics and anti-corrosion galvanisation is key.

In addition, the design of this type of structure must take into account the possibility of maintenance at heightIt is therefore common to incorporate interior stairways, inspection platforms and anti-fall safety systems.

Steel, a material that builds the future

In short, each type of metal structure responds to specific needs, but they all share a common denominator: their adaptability. In an environment where deadlines are shortened, energy efficiency is a priority and architectural aesthetics gain weight, metallic solutions are consolidating as one of the best choices. of the present and the future.

The use of steel not only makes it possible to respond effectively to today's structural challenges, but also opens the door to new possibilities in terms of sustainability and reuse. Your 100 % recyclability % makes it a key material for a more conscious and environmentally friendly construction.

Together, we build a stronger future.

It goes without saying that metal structures are among the most efficient and durable solutions in the world of construction. Whether it is because of their strength, versatility or their ability to withstand heavy loads, they are considered the preferred choice for all types of industrial, commercial and even residential projects.

However, like any material exposed to environmental conditions, steel requires proper maintenance to ensure its integrity and functionality over time.

Innovawith this article, aims to share tips and good practices to prevent corrosion, apply corrosion protection techniques and carry out periodic inspections to ensure the durability of your metal structures.

1. Preventing corrosion and wear and tear

If there is one enemy of metal structures, it is, without a doubt, the corrosion. As is well known, this is a phenomenon caused by exposure to oxygen, humidity and chemical agents which, little by little, if nothing is done to prevent it, will end up weakening the steel and compromising its stability.

Fortunately, there are several strategies to prevent it:

Selecting the right material

Use steels with alloys corrosion resistantas the stainless steel or galvanised steelwill make a big difference in the future.nd wet or corrosive environments. For example, galvanised steel is ideal for structures exposed to the elements, as the zinc acts as a protective shield.

Control of the environment

Whenever possible, it is advisable to avoid direct exposure of structures to extreme conditions, such as salinity in coastal areas or industrial environments with high levels of pollution. Where this is not feasible, physical or chemical barriers should be implemented to reduce the impact of these oxidising factors.

Efficient design

A good design manages to minimise the points of accumulation from humidity y dirt. For example, it is important to avoid tight corners or angles where water stagnates, a simple but very effective practice.

Cathodic protection

In structures buried or submergedsuch as pipes or piles, the cathodic protection is an effective technique that uses electrical current to prevent oxidation. This method is especially useful in critical infrastructures, such as bridges o offshore platforms.

Use of corrosion inhibitors

In controlled environments, such as storage tanks or piping systems, chemical inhibitors are used to slow down the corrosion process.

2. Painting techniques and corrosion protection

The application of protective coatings is one of the most common and effective practices to prevent corrosion on metallic structures. The following are the most commonly used techniques.

Surface preparation

Before applying any coatingis essential clean y prepare the surface. This includes the removal of rust, scale and contaminants by techniques such as sand blasting or the use of wire brushes. A well-prepared surface ensures a better adhesion of the coating.

First layers of protection

The application of a primer is essential to ensure adhesion of the coating and to provide an initial barrier against moisture and corrosive agents. Zinc-rich primers are especially effective for structures exposed to severe conditions.

Anticorrosive paints

There are specialised paints containing inhibitors from corrosionsuch as zinc or phosphate. These paints protect and act as an active shield against rust. In addition, they offer a wide range of colours and finishes, which effectively combine protection and aesthetics.

Epoxy and polyurethane coatings

For more demanding environmentsIn the chemical industry, such as chemical plants or coastal areas, epoxy and polyurethane coatings offer superior protection thanks to their chemical resistance and durability. These materials are ideal for structures that require a waterproof and impact resistant barrier.

Galvanisation

This process consists of covering steel with a layer of zincgalvanising, either by hot-dip galvanising or electroplating. Galvanisation is particularly useful in exposed structures outdoor applications, such as light poles, railings or bridge structures.

Intumescent coatings

At case of firethe coatings intumescent expand to form an insulating layer that protects the steel from high temperatures. This is an essential technique in buildings where fire resistance is a requirement.

3. Periodic inspections and their importance

As is to be expected, in order to maintain metal structures in perfect condition, the preventive maintenance is also key, as it allows for early detection of problems and avoid costly repairs in the future. Regular inspections allow signs of corrosion, cracks or deformation to be identified before they become a risk.

Critical points to review

As mentioned above, particular attention will have to be paid to the links, welds y exposed areas to moisture, as these are the points most vulnerable to corrosion and wear. It is also important to check the fastenersThe deterioration of such components, such as screws and bolts, can compromise the stability of the entire structure.

Use of advanced technology

Technology is constantly developing tools that make this work more efficient. Tools as dronesthermographic cameras and ultrasound significantly facilitates the inspection from difficult to access areas and provide accurate data on the condition of the structure.

Documentation and monitoring

Carrying a detailed record of each inspection, including photos and measurements is highly recommended, as it will allow progress to be monitored and corrective actions to be planned. In this sense, a maintenance management system (CMMS) will be of great help in organising this information.

Collaboration with experts

Having a team of professionals at maintenance of metal structures ensures that the inspections are carried out in a manner that is strict and in accordance with industry standards. In addition, experts offer customised recommendations based on the specific conditions of the structure to be maintained and protected.

4. Case studies of successful maintenance

To illustrate the importance of maintenance, these two case studies are perfect examples.

Metal bridge in coastal area

A bridge exposed to the salinity of the sea requires a intensive maintenance. For cases such as these, a system of cathodic protection combined with epoxy coatings. Six-monthly inspections will allow small areas of corrosion to be detected and repaired before they spread, ensuring the integrity of the bridge for more than 30 years.

Industrial building with high exposure to chemicals

In a chemical plantIn this case, metal structures are exposed to corrosive vapours. In this case, the following must be used intumescent coatings and establish a programme of quarterly inspections. This will prevent premature deterioration and reduce repair costs by 40%.

Conclusion

It can be stated that invest in maintenance will mean a considerable savings on repairs. By implementing preventive practices, such as corrosion protection, the application of appropriate coatings and regular inspections, not only do we extended lifespan of the structures, but it also ensures that the security of people and the continuity of projects.

At Ingea InnovaWe have years of experience in the design, construction y maintenance from metal structures. Our commitment is to offer durable solutions and efficient solutions that adapt to every need. If you need advice or specialised services, do not hesitate to contact us.

Together, we build a stronger future.

Undoubtedly, any professional will agree that, when it comes to constructing any type of building, one of the most important decisions is the choice of structural material. 

Generally speaking, two of the most commonly used options in the construction sector are the metal and concrete structures. Both have advantages and disadvantages that may make them more or less suitable depending on the type of project. 

In this article, we will analyse their characteristics, key differences and in which situations it is appropriate to opt for one or the other.

1. General characteristics of each type of structure

Before choosing between one type of structure or another, it is essential to know its main characteristics. Each of them offers unique properties that will have a decisive influence on the strength, durability, costs and speed of construction.

Metal structures

Mainly made of steel, a material that stands out for its strength, versatility and adaptability to different types of construction. They are widely used in industrial buildings, skyscrapers, bridges and large-scale structures.

Some of the advantages of steel in construction are as follows:  

Lightness and strength

It allows the construction of high-rise structures without overloading the foundations.

Speed of assembly

As it is pre-manufactured in the workshop and assembled on site, it reduces execution times.

Structural flexibility

It withstands seismic movements better due to its deformation capacity.

Sustainability

It is a recyclable material, which makes it a more environmentally friendly option compared to other building materials.

The use of metal structures also has certain disadvantages:

Maintenance cost

They require anti-corrosion treatments and fire protection.

Higher thermal conductivity

Additional insulation may be required to improve the energy efficiency of the building.

Concrete Structures

This is a material composed of cement, water, sand and gravel, which when set becomes a solid and resistant mass. It is commonly used in housing, public infrastructure and large-scale buildings.

Its advantages in construction are as follows:

Durability and resistance

It is a highly compression-resistant material with a very long service life.

Low maintenance

It does not need specific treatments, like steel, to prevent corrosion.

Thermal and acoustic insulation

It offers better thermal regulation and reduces noise transmission.

Affordable cost

In many cases, it is more economical compared to metal structures.

As in the previous case, there are also some negative aspects to be mentioned here:

Increased weight

It generates higher loads on the foundation, which can increase foundation costs.

Less structural flexibility

Its stiffness makes it more vulnerable to seismic movements if not combined with adequate bracing.

Slower construction process

It takes considerably longer to set and cure compared to the assembly of metal structures.

2. Key comparison between steel and concrete structures

In order to make the best decision for the project at hand, it is important to compare the two materials on the basis of different criteria:

Structural strength and behaviour

Steel structures are noted for their ability to withstand high tensile and bending stresses. They are more suitable for constructions that require long spans without intermediate columns.

Concrete structures, on the other hand, are very resistant to compression, which makes them ideal for multi-storey buildings and structures requiring high load-bearing capacity.

Cost of construction and maintenance

In general, steel tends to be more expensive in terms of material and assembly, but reduces construction time and labour. Concrete, however, while cheaper in terms of material, has a longer construction process and requires formwork and curing, which will ultimately result in a cost overrun on the overall construction. 

In terms of maintenance, steel requires more care due to the risk of corrosion, whereas concrete is more stable over time.

Construction speed

As can be expected from what has already been mentioned, metal structures allow for faster construction, as the parts are manufactured in the workshop and only require on-site assembly. Concrete requires more time for setting and hardening, which will delay the execution of the project.

Sustainability and recyclability

In this respect, steel is a clear winner, as it is 100% recyclable, making it a sustainable option in circular economy projects. Concrete, although durable, generates waste that is difficult to recycle and although techniques are being developed for its reuse in other projects, it may take a few more years before it becomes commercially interesting.

3. Which one to choose according to the type of project?

So, based on the information provided, which of the two systems should be chosen.

When to choose steel structures

In the following cases, metal structures are more suitable. 

High-rise buildings

Its lightness and strength allow the construction of skyscrapers and buildings with large spans without intermediate pillars.

Industrial structures
