Housing in Covid19 times

Example of assembly execution of our light cold-formed steel structure, steelframing.

There are issues in life that are not forgotten. When the inconveniences are of the magnitude of a pandemic such as Covid19, the will to keep pushing and the desire to do things better and better are determining factors for success.

Thanks to having an industrialized, agile, fast and safe system, we were able to comply, despite the necessary restrictions due to the Covid19 situation, with the assembly rhythms of the structure of this house.

On the 13th we began the assembly of the house and as can be seen in the video, it took 8 working days to completely finish the structure.

“Building has never been easier”

Advantages of our industrialized system – Light cold formed steel structures – Steel framing


The system enclosures achieve better insulation performance with less thickness, allowing a larger interior surface.
Greater quality control since many of the work units are factory-prepared.



Being an industrialized dry construction system, it is possible to reduce the conventional execution time by up to 50%.
The materials used are lighter than other construction systems, facilitating their handling and improving construction time.



Reducing the execution time represents a significant saving in the cost of labor.
The materials used are lighter, allowing to optimize the cost of the structure.
Reducing the execution time implies an anticipated return on investment.
By having the enclosures less thick, there is more useful surface available for sale.

Tourist offices project – Cold formed steel structures, assembled and assembled in one day

The need for this client is to have a network of tourist offices quickly through the main tourist spots in the region. With our structural system based on light cold-formed steel profiles, one office a day can be assembled and assembled on site, providing a solution to the need raised by the client.


In addition, the client obtains a product of the highest quality that allows them to obtain very high energy efficiency ratios, while using a recycled and recyclable material, helping to reduce CO2 emissions.

Efficiency. Quality. Ease.

Transportable offices in three modules of steel framing structure (cold formed steel)

We have already manufactured the three modules and their assembly will begin in September of this year near Valencia (Spain).

Types of cladding and slabs used by our clients / partners in the cladding of our structures

The enclosures are made up of different light layers placed dry on both sides (intrados extrados) of the structure, allowing quick installation. These layers can be adapted according to the technical needs of thermal and acoustic insulation of each project. This type of enclosure has two main advantages:
  • Reduced thickness, facing brick or concrete enclosures, allowing a greater interior surface.
  • Better insulation performance, since the layers respond to technical needs and do not need to be load-bearing

Enclosure with continuous insulation from the outside:

The floors are made up of mixed concrete slabs with a collaborating sheet. The advantages of this type of slab are:
  • It is not necessary to form or prop up: The collaborating sheet works as formwork and avoids propping, allowing a faster construction.
  • Reduced depth: the corrugated metal sheet works together with the concrete by means of connectors allowing reduced slab edges, adaptable according to project needs.

Mixed slab slab with collaborating sheet:

Depending on the needs of the project, roofs can be designed in two ways:



  • Roof on slab: solution to support higher loads, as in the case of walkable roofs, for example.
  • Deck cover: lightweight solution to run on non-passable deck

“Deck” type roof solution:

Advantages of the steel framing structure or light cold formed system

The structure of the Steel Frame system stands out compared to other industrialized systems, such as construction with precast concrete panels, due to its lightness. By being made up of linear elements, it is possible to optimize the relationship between weight and the strength necessary to support the structure. As a material, galvanized steel has the following advantages:

  • Optimum strength-to-weight ratio among construction materials today
  • 100% recyclable
  • Non-combustible: does not burn and will not contribute as fuel to the spread of a fire
  • Inorganic: does not rot, does not suffer from xylophages, does not suffer from cracks
  • Dimensionally stable against moisture: does not expand or contract with moisture content.
  • Certified and industrialized quality: the material is manufactured under strict control and is shaped by numerical control machines

Definition of Steel Framing or light cold-formed steel system

The Steel Frame system is an industrialized construction system based on galvanized steel linear element structures. This system stands out from other industrialized systems due to its lightness and its economy. Derived from the traditional construction with a wooden structure (Wood Frame), these structures form a supporting framework that can act as both a vertical structure and a horizontal structure. The Steel Frame system is characterized by its:

· Lightness and isolation. The Steel Frame system is lighter both in structure and in enclosures. In addition, it allows to achieve better insulation performance with less thickness of closings, gaining interior surface.

· Industrialization and speed of construction. It is an industrialized and dry construction system, which is why the execution times are dramatically reduced compared to conventional construction systems.

· Economic savings. Thanks to the combination of the above characteristics, the reduced weight saves the cost of the structure and the reduction of the execution time saves the costs of labor and financing

Why cold steel is growing in popularity and will become the preferred construction method


The advantages of this system compared to concrete and wood are basically speed, effective profitability, acoustic and energy efficiency, ease of planning and the perfect results that are achieved with ease of execution, avoiding errors and deviations.

“Light Steel Framing”, a light cold-formed steel system, has existed since 1850. However, it was not until a few years ago, thanks to technology, improvements in the calculation capabilities for its structural justification and above all thanks to the possibilities of industrializing manufacturing, when this system has exploded, becoming a world reference in construction.

Its benefits include the shortening in the execution phases, the possibilities of scaling the manufacturing and the reduction of the construction process cycles. In addition, the low number of waste that is generated, the best execution results and cost efficiency, make this system the leading system when it comes to being selected by many architects.

Although in some types of construction the cost of structural materials may be higher than those used in conventional systems, in reality a general saving is achieved in the project. This saving is motivated by lower labor costs, personnel not specially qualified due to the simplicity of installation, lower total building weights that mean savings in other items such as, for example, savings in the foundations.


Much of the time savings of the total construction is achieved in the structural phase. The fabrication is carried out while working on the adaptation of the terrain and the foundation / slab. Once manufactured, it is taken directly to the job site and the installation is very simple and fast. In this phase, the cold-formed steel system is 10 times faster than conventional systems. Therefore, this time saved in the beginning can be used to execute other items of the project.

As an addition to the initial time savings, it is important to mention that by not having a place for human error in the installation on site, a lot of lost time and delays are avoided. You avoid having to re-measure, you avoid having to adapt and correct on site, and the execution of several games at the same time overlaps (unthinkable with conventional systems).



Whether we are talking about the moment of manufacture, the moment of material handling or the moment of installation, lightness is a key element in this system.
When manufacturing, no specific machinery is needed to move materials. This factor shortens manufacturing times and reduces the number of labor required in the process.
During transport, its lightness reduces transport costs since it allows to take advantage of the transport space of trucks or containers.
Finally, at the time of assembly, its lightness facilitates installation, requiring few human resources and very few lifting mechanics.



It allows great design freedom. The architects can create the spaces freely and the system takes care of reproducing them exactly.
Whether we are talking about skyscrapers, industrial buildings, offices, public buildings, single-family homes or residential buildings, the system fits for its versatility when it comes to being able to adapt and coexist with conventional systems such as concrete or rolled steel.

Cold rolled steel, in combination with concrete and / or rolled steel, is a powerful solution for building applications at different heights. It works very well also for lifts of new heights on buildings built for its lightness and ease of execution.
