Some steel leaves the mill as "basic shapes" such as I-beams, flat plates, or sheets, but some pieces call for additional work before they are ready to use.
Fabrication is the process of building up a more complex structure, such as a bridge girder or a truss, from simpler shapes. These may be riveted, bolted, or welded together to create the finished piece.
Machining is the process by which rough castings or forgings are given their final, more precise, forms. The machines used include lathes, milling machines, and cutters of various types.
