H-beam steel is mainly used for industrial and civil construction beams, columns components.

Industrial steel structures bearing bracket steel supporting structure.
Piles and underground engineering
Petrochemical industrial equipment construction and electricity
Large-span steel bridge components
Shipbuilding, machinery manufacturing framework
Trains, cars, tractor beam bracket
Port conveyors, high speed shutter bracket
H-beam steel section is an economical, 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 5 million tons, but our H-shaped steel annual production capacity of 1.2 million tons, the market demand is huge.
