Description
Welded structural steel hollow sections – compliant with EN 10219 and EN 10210. Structural tubing for metal frameworks and load-bearing applications, manufactured through cold-formed ERW (Electric Resistance Welded), hot-formed longitudinal welding, cold-formed and submerged-arc spiral welding (SSAW), or cold-formed and submerged-arc longitudinal welding (LSAW).They provide rigidity, geometric stability, and predictable mechanical performance in service, ensuring easy integration into welded assemblies or mechanically fastened structures.
Applications
Civil and industrial steel structures (warehouses, storage halls, commercial buildings); load-bearing elements such as columns, beams, trusses, and bracings; walkways and platforms; equipment racks and frames; photovoltaic support structures; and any application where an optimal balance between strength, weight, and dimensional precision is required.
Key Advantages
-
Structural compliance with EN 10219 (cold-formed) and EN 10210 (hot-finished), ensuring certified performance for construction.
-
Stable geometry and controlled tolerances that simplify on-site alignment and improve welding consistency.
-
Good weldability and machinability (cutting, drilling, beveling), enabling fast integration into frames, trusses, beams, and columns.
