A steel structure is a metal structure which is made of structural steel components connected to each other to carry loads and provide rigidity. Because of the high strength of steel, these structures are reliable and require less raw material than some other types of structure such as concrete.

Structural steel differs from concrete in its attributed compressive strength as well as tensile strength. Strength – Having high strength, stiffness, toughness, and ductile properties, structural steel is one of the most commonly used materials in commercial and industrial building construction.
