The combination of excellent mechanical properties with good formability makes this steel grade an ideal solution for this ski lift pylon.
These grades comply with the EN 10149-3:2013 standard, which describes normalised or normalised rolled steels.
Normalised or normalised rolled steels are characterised by a guaranteed minimum yield strength, controlled metallurgical purity and a fine grain structure.
Like the corresponding grades obtained by thermomechanical rolling, normalised or normalised rolled steels combine excellent mechanical properties, such as high strength, fatigue resistance and toughness, with good formability. Their higher carbon content may affect their weldability. Nevertheless, these grades meet the specifications for normalised steel.
Normalised or normalised rolled steels are mainly used for the construction of bridges, containers, pylons and other architectural structures.
