Steel fabrication is the building of metal structures by means of cutting, bending and assembling processes. Fabrication comprises various metalworking specialities. Steel fabrication is a value added process that involves the construction of structures from various raw materials. These are based on engineering drawings which include precise measurements which then move to the fabrication stage and finally to the erection of the final project.Structural steel differs for example from concrete in its attributed compressive and tensile strength.In steel fabrication, having high strength, stiffness, toughness and ductile properties, structural steel is one of the mostly commonly used materials in commercial and industrial building construction. Structural steel can be developed into nearly any shape which are bolted or welded together in construction.  Structural Steel can be erected as soon as the materials are delivered on site, whereas concrete must be cured at least 2 weeks after pouring before construction can continue, making structural steel a schedule friendly construction material.
