What are modular prefabricated steel frame buildings?
Modular prefabricated steel frame buildings are safe and efficient spaces for storage, logistics, industry, or commerce. They can be assembled on-site for temporary use or for the short, medium, or long term. If needed, they can be dismantled and reassembled in a different location.
These modular, removable steel frame buildings can be easily adapted to the changing needs of companies. It is possible to increase or decrease their size if necessary, and they can also be attached to other existing or later-assembled modular prefab buildings if the company's needs require it. They can house warehouses for all types of raw materials and goods, testing or quality control spaces, industrial areas, commercial and administrative zones, and auxiliary spaces for businesses, among other uses.
VALL Steel Frame Buildings: A wide range of secure and sustainable buildings.
VALL Steel Frame Buildings, made of steel or aluminum structure, provide a solution for businesses and organizations in case of contingencies or to seize opportunities and grow in an agile and cost-effective way.
There are different types of modular prefabricated steel frame buildings to choose from, allowing you to select the one that best suits your company’s needs and location.

VALL modular prefabricated steel frame buildings are designed according to European manufacturing and assembly standards EN13782, EN1090, and structural Eurocodes.
EN 13782
This EU standard sets the safety requirements for the design, calculation, manufacturing, installation, maintenance, and use of mobile tents and temporary structures with a floor area greater than 50 m², and its compliance is mandatory.
At VALL, we apply this standard to all our modular prefabricated steel frame buildings, regardless of their size, to ensure the safety of people, goods, and assets they house. Whether the solutions are for temporary use, lasting just a few days, or remain in the same location for many years with the same or a different use.
UNE EN 1090
It is the set of regulations established by the EU that governs the manufacturing and assembly of steel and aluminum structures, such as our modular prefabricated steel frame buildings SteelSpace, MaxiSpace, EcoSpace, and AluSpace.
At VALL, we strictly adhere to this standard to ensure the quality and reliability of our modular steel frame buildings, with robustness, fire and fatigue resistance, as well as the durability of every piece, component, and element that forms part of their metal structure.
Structural Eurocodes
The Structural Eurocodes are a set of voluntary European standards that establish methods for the design and calculation of structures to ensure safe and resilient buildings. Although not mandatory, as a commitment to quality, at VALL, we voluntarily adhere to them in all our modular prefabricated steel frame buildings.
