H-shaped steel is a kind of economical section steel with better mechanical properties of section, which is developed from the optimization of I-shaped steel. Especially, the section is named after the English letter "H". Its characteristics are as follows:
Wide flange, large lateral stiffness. Strong bending resistance, better than I-beam About 5% - 10%.
The two surfaces of the flange are parallel to each other, which makes the connection, processing and installation simple.
Compared with welded I-beam, it has low cost, high precision, small residual stress, no need for expensive welding materials and weld detection, and can save about 30% of the production cost of steel structure. Under the same section load, the weight of hot-rolled H steel structure is less than that of traditional steel structure. Compared with concrete structure, hot-rolled H steel structure can increase the use area by 6%, while the structural dead weight reduces the structural design internal force. H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various sections, which can greatly meet the needs of engineering design and production.
There are three types of European standard H-shaped steel: HEA type, HEB type and HEM type. The main materials are S235JR S275JR S275J0 S275J2 S355JR S355J0 S355J2 S355NL, etc
