H-beam is a new type of economic construction steel, H-beam cross-sectional shape is economical and reasonable, good mechanical properties, rolling at all points on the cross-section of the extension of more uniform, low internal stress, compared with ordinary I-beam, has the advantages of large cross-sectional modulus, light weight, metal saving, can make the building structure to reduce 30-40%; and because of its legs inside and outside parallel, the end of the leg is right angle, assembled into a combination of components, can save welding, riveting Workload up to 25%. Commonly used in large buildings (such as factory buildings, high-rise buildings, etc.), bridges, ships, lifting machinery, equipment foundations, brackets, foundation piles, etc., which require large bearing capacity and good cross-sectional stability.
