Compared with ordinary hot rolled H-beam steel, heavy hot rolled H-beam steel flange or web thickness is larger (more than 70mm), which can reduce the welding workload and improve the safety of structural components. In recent years, some cross-sea bridges, drilling platforms, large exhibitions, shopping centers and other large space high-rise buildings and facilities, more inclined to use large height, large span and large size of the structural components.

Heavy H-beam steel is widely used in a variety of civil and industrial building structures, various large-span industrial plants and modern high-rise buildings, especially in areas of frequent seismic activity and high-temperature working conditions of industrial plants.
