H beam is a new kind of economic construction steel. H beam cross-section shape of economic rationality, good mechanical properties, rolling cross-section extends over all the points on a uniform internal stress is small, compared with the ordinary I-beam, with a section modulus, light weight, saving advantages of the metal, construction can structure to reduce 30-40%; and its parallel inner and outer legs, leg-side is the right angles, assembled into composite components, saving welding, riveting work amounted to 25%. Commonly used in the required commitment cut capacity, good stability, a large section of building (such as factories, high-rise buildings, etc.), as well as bridges, ships, hoisting and conveying machinery, equipment foundation, frame, foundation piles. H-beam steel by the word developed from the optimization of the mechanical properties of a section of the economy more good cross-section of steel, especially in cross-section with the letters "H" the same as the name. Its characteristics are as follows: → flange width, lateral stiffness. Bending ability. → flange allows connection of two parallel surfaces, processing, and ease of installation. Compared with the I-beam welding → photo, low cost, high precision, residual stress, without the expensive welding and weld testing, saving about 30% of the cost of steel production.
