There are many advantages to constructing with steel: the strength to weight ratio is excellent, metals join easily, efficient shapes are available, etc. These advantages create challenges that are best solved by a good understanding of how the metals actually perform in a structure. Structural steel shapes are suitable for a wide variety of uses. For example they are used in, building frames, roof trusses, floor framing, bench frames, gates, fences, cattle grids, scaffolds, tank stands, television towers, car trailers, rails, etc. Most structural steel failures occur at connections, where a beam connects to a column, where a joist connects to a beam, etc. The Structural Engineer must design the steel members and give guidelines for the connections. The cold-formed sections are suitable for all types of welding such as spot welding, seam welding, projection welding, butt and groove welding, plug welding and arc welding. All of these are applicable to both uncoated and zinc coated sections.
