H-beam is a new type of economic construction steel, H-beam cross-section shape is economically reasonable, good mechanical properties, rolling the cross-section on the extension of the points more uniform, internal stress is small, compared with the ordinary I-beam, has the advantages of large cross-section modulus, lightweight, metal saving, can make the building structure to reduce 30-40%; and because of its legs parallel to the outside and the inside of the leg, the leg end is a right angle, assembled and combined into a component, can save welding, riveting Workload up to 25%. Commonly used in the requirements of large capacity, cross-section stability of large buildings (such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting and transport machinery, equipment foundations, brackets, foundation piles and so on.
H-beam steel is optimised by the development of I-beam steel section mechanical properties of a more excellent economic section of steel, especially section and the English letter 'H' and the same name. Its characteristics are as follows.
Wide flange, large lateral stiffness.
Strong bending resistance, about 5-10% more than I-beam.
The two surfaces of flange are parallel to each other, which makes connection, processing and installation easy.
Compared with welded I-beam, it has low cost, high precision, low residual stress, no need for expensive welding materials and weld testing, saving about 30% of steel structure production cost.
Under the same section load . Hot rolled H steel structure is 15-20% lighter than traditional steel structure.
Compared with concrete structure, hot rolled H steel structure can increase the use area by 6%, while the structure self-weight is reduced by 20% to 30%, reducing the internal force of structure design.
H-beam can be processed into T-beam, and honeycomb beam can be combined to form various cross-section forms, which greatly meets the requirements of engineering design and production.
