1.H beam is an economical cross-section and high-efficiency profile, also known as wide-flange I beam. The inner and outer sides of the flanges are parallel or nearly parallel, and the ends are at right angles, thus it is named parallel-flange I beam. The thickness of the web is smaller than that of ordinary I beams, while the width of the flanges is larger. Its section modulus, moment of inertia, and strength are superior to those of ordinary I beams with the same unit weight. 

2.It has a strong load-bearing capacity and can save 10% - 40% of metal. It is convenient for assembly and combination, and can save about 25% of the welding and riveting work, accelerating the construction speed of the project. All parts are arranged at right angles, giving it strong bending resistance in all directions. During rolling, the elongation at each point of the cross-section is uniform, and the internal stress is small.

3.H beam is Mainly used for beams and columns in civil and industrial building structures, such as long-span industrial plants and high-rise buildings; In the industrial field, it is used for bearing supports, pipe supports, etc. It is also used in large Bridges, heavy equipment, highways, ship skeleton, mine support, foundation treatment and dam engineering.
