H beam is a new type steel beam for economic steel construction. The section shape of H-beam is economical and reasonable with good mechanical properties. The extension of each point on the section is more uniform and the internal stress is small during rolling. Compared with ordinary I-beams, it has the advantages of large section modulus, lightweight, and metal saving, which can make structure buildings' weight reduced by 30-40%. Bellow are specific characteristics.
1. Wide flange and large lateral rigidity. Strong bending resistance, about 5%-10%biggerthan I-beam.
2. The two surfaces of the flange are parallel to each other, which makes the connection, processing and installation easily.c
3. Compared with welded I-beams, it has advantages of low cost, high precision, low residual stress, no need expensive welding materials and weld inspection, and saves about 30% of the steel structure production cost.
4. Under the same section load. The weight of hot rolled H steel structure is 15%-20% lighter than the traditional steel structure.
5. Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, while the structure's own weight is reduced by 20%-30%, which reduces the internal force of the structural design.
