STRUCTURAL STEEL
STRUCTURAL STEEL
The structural steels are steels manganese-carbon, characterized by a
guaranteed minimum tensile strength and tensile yield strength.
Structural steel have a good ductility and is the most common
material, used in civil engineering, mechanical constructions and
machinery industry. In particular, it is suitable to be resistant to static
stresses.
