General Structural Steels

Technical Features of General Structural Steels
General structural steels are steels that usually contain low carbon and are non-alloyed. They are very functional with their  
weldability and ideal strength. They are used in applications which require high strength and less weight. These steels are used more than
other steels because they are mostly used in construction sites. In Euro Norm the materials are named according to their yield strength.
