Whether H-beam belongs to section steel?

Some people do not know whether the H-beam belongs to section steel , the following for everyone to answer why H-beam is section steel . H-beam is made of I-shaped steel optimized development of a cross-section more excellent mechanical properties of the economic section of steel, especially the cross-section with the English letter "H" the same name. Its characteristics are as follows:
First: the flange width, lateral stiffness. Bending ability.
Second: the two flanges parallel to each other so that the connection, processing, installation is simple.
Third:compared with welding torch, low cost, high precision, small residual stress, without expensive welding materials and weld testing, saving about 30% of the cost of steel production.
Fourth:the same section load. Hot-rolled H steel structure than traditional Tong structure weight reduction of 15% -20%.
Fifth: compared with the concrete structure, hot-rolled H steel structure can increase the use of 6% of the area, while reducing the weight of the structure by 20% to 30%, reducing the structural design of internal forces.
It is predicted that in 2005 China's H-beam demand of about 2.5 million tons in 2010 demand of 5 million tons, but at present, China H-beam annual production capacity of 1.2 million tons, the market demand is huge. Katalor industry also export section steel to other countries .we can stock 500 thousand tons every year. Please contact us if you want to know more information.
