Used in different requirements of the metal structure, whether it is under bending moment, pressure load, eccentric load shows its superior performance
H type steel has the following characteristics:
The inner and outer sides of the flange of H-beam are parallel or close to parallel, and the flange ends are at right angles, hence the name parallel flange I-beam. The web thickness of H-beam is smaller than that of ordinary I-beam with the same height as the web, and the flange width is larger than that of ordinary I-beam with the same height as the web, so it is also named wide-edge I-beam. Determined by the shape, H section modulus, moment of inertia and the corresponding strength are significantly better than the same single weight of ordinary I-beam. Used in different requirements of the metal structure, whether it is under bending moment, pressure load, eccentric load shows its superior performance, can be compared with ordinary I-beam greatly improve the bearing capacity, save metal 10% ~ 40%. H-beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% of metal for various truss structures. Because its flange is parallel to the inner and outer sides, and the edge ends are at right angles, it is convenient to assemble and combine into various components, thus saving about 25% of the welding and riveting workload, greatly speeding up the construction speed of the project and shortening the construction period.
H-beam is widely used, mainly:
Various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high temperature working conditions; large-scale buildings with large bearing capacity, good cross-sectional stability and large span Bridges; heavy equipment; highways; ship skeletons; mine support; foundation treatment and dam engineering; various machine components.

Do you know ten key points about steel structure forms?
Civil buildings choose appropriate structural forms based on the height of the building, its functional use, seismic performance, and ground hydrological survey reports. Today, I will introduce ten key points about 'structural forms' in steel structure buildings.
