Welded mesh

Welded mesh made from high-ductility hot-rolled welding steel:

  • class B450C (Italy)
  • class B500A (France)
  • class B550A (Austria)
  • class B500B (France, Germany and Switzerland)

Suitable for use in seismic areas. Produced in standard formats.

Chemical composition

The weldability of our welded mesh is guaranteed by the chemical analysis of the heats and the equivalent carbon content.

Mechanical features

The standardisation of the production process made it possible to obtain the homogenisation and repeatability of the mechanical characteristics.
The high ductility of the product is expressed by the following parameters:

  • Optimised tensile strength/yield stress ratio at the minimum and maximum values set out by design standards;
  • High elongation at maximum AGT load.
