H beams are widely used in many constructions,such as building,highway,bridge,railway,tunnel,petroleum chemical industry and electric power industry equipment structure.H beam is environmentally friendly and reduce the nuisance dusts.H beam also can save the working time,because it is easy to carry and can be used in any weath.
The inner and outer sides of the flange of the H-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of the H-shaped steel is smaller than that of the ordinary I-beam with the same height of the web, and the width of the flange is larger than that of the ordinary I-beam with the same height of the web, so it is also called wide-edge I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beams are significantly better than ordinary I-beams of the same single weight. Used in metal structures with different requirements, whether it bears bending moment, pressure load, or eccentric load, it shows its superior performance. Compared with ordinary I-beams, it can greatly improve the bearing capacity and save 10% to 40% of metal. H-shaped steel has wide flanges, thin webs, multiple specifications, and flexible use. It can save 15% to 20% of metal in various truss structures. Because the inner and outer sides of the flanges are parallel and the edges are at right angles, it is easy to assemble and combine into various components, thereby saving about 25% of the welding and riveting workload, which can greatly speed up the construction speed of the project and shorten the construction period.

H-shaped steel can be produced by welding or rolling. Welding H-shaped steel is to cut the strip steel with suitable thickness into suitable width, and weld the flange and web together on the continuous welding unit. Welded H-shaped steel has disadvantages such as large metal consumption, difficulty in ensuring uniform product performance, and limited size specifications. Therefore, H-shaped steel is mainly produced by rolling method.
Due to the above advantages, H-shaped steel is widely used, mainly for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activities and high-temperature working conditions; requirements Large bridges with large bearing capacity, good section stability, and large spans; heavy equipment; highways; ship skeletons; mine support; foundation treatment and dam engineering; various machine components.
