Fabrication is a process which accords shape and size to an element made of metal. This involves a number of process and technology. With regular advancements in technology there is a paradigm shift taking place as to how the industry surface.
Steel fabrication is a large industry in USA is most active in construction work. The raw steel produces many parts of building like windows, gates, staircase grills and what not. Hence no building is complete without the involvement of structural steel fabrication and its installation. The process is not limited to building parts it plays a major role in large projects like bridges, railways and industry in USA.
The process envisages the following steps.
Hot rolled steel smelted using an electric arc furnace. The use if ferrous scrap results in recycled content of more than eighty percent. The produces is in shape of hot rolled structural shape - beams, angles and plates.
Hollow structural sections are also manufactured the producers.
The service centers act as warehouse and are instrumental in initial processing before actual fabrication takes place.
The fabrication by major companies involves detailed drawings, cutting, shearing, welding and bolting. The complex process is guided by drawing by structural steel fabrication engineers.
Installation on spot fitting, welding, bolting on the construction site is the last stage of action.
The production of hot rolled structural steel exceeds way beyond eight million tons in USA and is constantly increasing. At present there are three major manufacturers in United States that account for more than ninety percent of the produce. A large percentage of the produces is utilized in building work.
