H- beam is to optimize the mechanical properties developed from a cross-section of more excellent economy by word-section steel beam, especially section and letter "H" the same name. Its features are as follows: flange width, lateral stiffness. Strong resistance to bending. Two surfaces parallel to each other so that the connecting flanges, processing and easy to install. Compared with the photo-beam welding, low cost, high accuracy, low residual stress, without expensive welding materials and weld inspection, saving about 30% of steel production costs. Under the same section load. Hot-rolled steel H Tong structure than traditional weight reduction of 15% -20%. Compared with the concrete structure, hot-rolled steel H can be increased by 6% of the use of space, and reduce the structural weight by 20% to 30% reduction in the structural design of internal forces. H-beam steel processed into T cellular beam cross section may be combined to form various forms, great to meet the needs of the engineering design and production. H-shaped steel is mainly used for engineering, plant and equipment, machinery and equipment, bridges, highways, houses, etc; good mechanical and physical properties, solid, energy conservation and environmental effects. H-beam is an economical section steel, widely used in industrial, construction, bridges, oil rigs, etc. It is predicted that in 2005 China's H-beam demand of about 2.5 million tons, in 2010 the demand for five million tons, but the country H-shaped steel annual production capacity of 1.2 million tons, the market demand is enormous.
