Structural steel is a category of steel used as a construction material to build the frame of a building. A structural steel shape is a profile, formed with a specific cross section and following certain standards for chemical composition and mechanical properties. Structural steel shapes, sizes, composition, strengths, storage practices, etc., are regulated by standards in most industrialized countries. Structural steel shapes include beams, channel, angle, plate, and HSS (hollow structural section). Dallas-based PIF fabricates and erects structures incorporating these structural steel shapes to fulfill our clients construction requirements.
