The inner and outer flanges of H-beams are parallel or nearly parallel, and the flanges end at right angles, hence the name parallel flanged I-beams. The web thickness of H-shaped steel is smaller than that of ordinary I-steel with the same high web, and the flange width is larger than that of ordinary I-steel with the same high web, so it is also named wide flange I-steel. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight. Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load shows its superior performance, can be compared with ordinary I-steel greatly improve the bearing capacity, saving metal 10% ~ 40%. H-shaped steel has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% of metal in various truss structures.
Various civil and industrial building structures; All kinds of large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high temperature working conditions; Large Bridges with large bearing capacity, good cross-section stability and large span are required; Heavy equipment; Expressway; Ship frame; Mine support; Foundation treatment and dam works; Various machine components.
