The main structure of truss halls is usually made using transverse supporting frames, which consist of steel frames with a lattice stiffener and a horizontal bottom chord. The segmented structure of lattice stiffeners is usually welded and, during the assembly, jointed together and fixed to the solid-walled double T-bar columns using screw connections.
DIn the construction of truss halls, GAL-STAL uses typical structural steels. For mounting joints we use high-strength bolts, and the painted parts of the construction are shot-blasted or sand-blasted to the cleanliness degree SA 2,5. Afterwards, the steel structures are protected against corrosion by suitable painting materials, which guarantee the required thickness of the dry coating, i.e. not less than 120 µm. In terms of colour range, we use the RAL paint system. Upon request, we are able to provide additional corrosion protection for the indicated construction elements using zinc plating.
In order to ensure the highest standards of our projects:
- we use only certified raw materials from proven suppliers
- we follow the highest standards for the production of steel structures
- we comply with the applicable requirements and standards to ensure safety during the operation of our facilities
