Steel H Iron Standard H Beam Sizes Q235 Q345 High Strength Metal Structural

♦ Feature

The inner and outer sides of the flange of H-beam are parallel or nearly parallel, and the flange ends are at right angles, so it is named parallel flange I-beam. The thickness of the web of the H-beam is smaller than that of the common I-beam with the same height of the web, and the flange width is larger than that of the common I-beam with the same height of the web, so it is also named wide-edge I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than ordinary I-beam of the same single weight.

Used in metal structures with different requirements, whether it is subjected to bending moment, pressure load, or eccentric load, it shows its superior performance. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by 10% to 40%. H-beams have wide flanges, thin webs, many specifications, and flexible use. They can save 15% to 20% of metal when used in various truss structures. Because the inner and outer sides of the flanges are parallel, and the edge ends are at right angles, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting workload, which can greatly speed up the construction speed of the project and shorten the construction period.

♦ Application

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 bridges requiring large bearing capacity, good section stability, and large spans ;heavy equipment;highway;ship skeleton;mine support;foundation treatment and dam engineering;various machine components.
