Steel Structure Painted H Structural steel
H section steel is a kind of economical section high efficiency profile with more optimized sectional area distribution and stronger weight ratio. It is named after the English letter "H". Because all the sections of H steel are arranged at right angles, H steel has been widely used in all directions for its advantages of high bending resistance, simple construction, cost saving and light weight.
The inner and outer sides of the flange of H-shaped steel are parallel or nearly parallel, and the end of the flange is at right angles, hence the name of parallel flange I-beam. The web thickness of H-shaped steel is smaller than that of ordinary I-shaped steel with the same height of the web, and the flange width is larger than that of ordinary I-shaped steel with the same height of the web, so it is also called wide flange I-shaped steel. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously superior to those of ordinary I-beam with the same unit weight. When used in metal structures with different requirements, whether it bears bending moment, pressure load or eccentric load, it shows its superior performance, which can greatly improve the bearing capacity compared with ordinary I-beam and save 10%~40% of metal. H-shaped steel has wide flange, thin web, multiple specifications and flexible use. It can save 15%~20% metal when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge ends are at right angles, it is convenient to assemble and assemble various components, which can save about 25% of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.
Because of 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 in areas with frequent seismic activities and under high temperature working conditions; Large bridges with large bearing capacity, good section stability and large span are required; Heavy equipment; expressway; Ship skeleton; Mine support; Foundation treatment and embankment works; Various machine components.
