Galvanized H-beam is a type of structural member made from hot-rolled or welded H-beams, and it is coated with a metal protective layer through the hot-dip galvanizing process. Its cross-section takes the shape of an H. Since the various parts of H-shaped steel are arranged at right angles, it possesses excellent advantages such as strong bending resistance, simple construction and light structural weight in all aspects, and has been widely applied.
