metal structures

"The metal structures are produced for external projects, or, in many cases, with special specifications and designs, and consist, essentially, of optimising costs and reducing production times."


All joints are fixed, where possible, with 8.8 or 10.9 class bolts, allowing for a quicker assembly during construction, and ensuring correct anti-corrosion protection which is an essential guarantee of the product's quality. 

Raw Materials

All raw materials are accompanied by their respective conformity certificates, with details of the tests carried out: chemical composition, mechanical properties, dimensions, etc.

Pieces are generally made of S275 (F2430) and S355 (Fe510) steel, from properly selected suppliers, approved by our quality department.

Protection and Finishes

Anti-Corrosion Protection and Surface treatment

The anti-corrosion protection applied to the metal structure is decided at the appropriate time during the design process, depending on the conditions of the area where the building will be constructed.
The treatment and finishing scheme will be designed to correspond with many different types of environments and the necessary life of the structure.



Passive Fire Protection
Designing painting plans for passive fire protection, in accordance with safety regulations concerning fire, defining the intended resistance to fire level (R30, R60 or R90), the section factor of the metal structures to be protected and the critical (or collapse) temperature of the structure (to be defined by the project designer). The section factor links the area to be painted with the steel volume of the structure.

Colours
The colours used in final finishes, in acrylic or polyurethane paints, are chosen by the client, in accordance with the available RAL colour chart. 

Manufacture
The materials used in our metal structures are measured, cut, perforated and marked using automated production lines, linked by transport systems. This equipment is linked to and programmed directly from the project planning room, minimising the chances for human error and ensuring high levels of reliability and size conformity.
ADVANTAGES OF USING STEEL
- Freedom in architectural planning
- Possibility to create more usable space
- Flexibility in adapting, extending, refurbishing and changing the use of buildings
- Compatibility with other materials
- Shorter time needed for construction work
- Smaller load on foundations
- Quality guarantee
- Precision in construction, with all measurements made in mm, guaranteeing level, upright structures
- Can be recycled and environmentally friendly. Steel is 100% recyclable and the structures can be disassembled and reused.
