Explanation

The section shape is H-shaped section steel. With large section modulus, it can bear large bending and torsion loads and complex loads under the same section area. It can obviously save materials and reduce self weight when used in engineering structures. The main difference from I section steel is that the inner and outer sides of its flange are parallel to each other and all parts are assembled at right angles to form various components, which is convenient and can save weld or riveting workload. (GB/T11263-2010) can be divided into wide flange (HW), medium flange (HM), narrow flange (HN), thin-walled (HT), and pile type (HP). The steel grades of the steel are non alloy structural steel and low alloy high strength steel, which are mainly produced by special rolling mill. It is often used in large bridges, high-rise buildings, heavy equipment, highways, airports, foundation piles, stem and other engineering structures that require large bearing capacity and high section stability.
