Structural steel is used to construct residential and commercial buildings, warehouses,
aircraft hangers, hospital and school buildings, metro stations, stadiums, bridges, etc.
Construction of these structures is done with the help of structural steel design components
such as channels, beams, angles, and plates. The rolled plates are used in the web and flanges of plate girders, plated beams and chord members, and web members of the truss bridge girders.
The rolled steel plates are used in special plate structures, e.g., shells, rectangular and
circular steel tanks and steel chimneys.
