H - shaped steel is a new type of economical construction steel.
H section shape is economical and reasonable, good mechanical properties, rolling on the section of each point is more uniform extension, small internal stress, compared with ordinary I-beam, has the advantages of large section modulus, light weight, metal saving, can reduce the building structure by 30-40%; And because of its legs inside and outside parallel, the leg end is a right Angle, assembled into components, can save welding, riveting work up to 25%. It is often used to require large bearing capacity, good section stability of large buildings (such as workshops, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundation, supports, foundation piles, etc.
H-section steel is a kind of economic section steel with better mechanical properties, which is optimized and developed from I-section steel. In particular, the section is the same as the English letter "H". Its characteristics are as follows:
→ wide flange, large lateral stiffness. Strong bending ability.
→ The two surfaces of the flange are parallel to each other, which makes it easy to connect, process and install.
→ Compared with the welding I beam, low cost, high precision, small residual stress, without expensive welding materials and weld detection, saving steel structure production cost of about 30%.
→ Under the same cross section load. The weight of hot rolled H steel structure is 15%-20% less than that of traditional steel structure.
→ Compared with concrete structure, hot rolled H steel structure can increase the use of 6% of the area, and the weight of the structure to reduce 20% to 30%, reduce the internal force of the structure design.
→H type steel can be processed into T type steel, honeycomb beam can be combined to form a variety of section forms, greatly meet the needs of engineering design and production.
H-beam is mainly used in engineering, plant equipment, mechanical equipment, Bridges, highways, houses, etc. Good mechanical and physical properties, firm, energy saving and environmental protection effect. H-section steel is a kind of economic sectional steel, widely used in industry, construction, Bridges, oil drilling platforms, etc. It is predicted that the demand for H-section steel in 2005 is about 2.5 million tons, the demand for H-section steel in 2010 is 5 million tons, but the current annual production capacity of H-section steel is 1.2 million tons, the market demand is very huge.
