Steel pipe is not only used to transport fluids and powdery solids, exchange heat, manufacture machinery parts and containers, it is also a kind of economic steel. It can reduce weight, save 20%-40% metal material, realizing the industrial mechanized construction. Making highway bridges with steel tubes can not only save steel material , simplify construction difficulty, but also greatly reduce the area of protective coating and save investment and maintenance cost.
Hot rolled products have high strength , good toughness, easy processing and good weldability. , it is widely used in construction, machinery, boiler, pressure vessel and other manufacturing industries. After annealing, it is processed into ordinary cold rolling coil .
Cold rolled steel coil is mainly used in automobile, shipbuilding, electric power, coal, light industry, household appliances,hardware and other industries, such as used in engineering machinery, transportation machinery, construction machinery, agricultural machinery and light industrial and civil industries of general structural parts and stamping parts, as well as manufacturing sewing machine, bicycles, farm machines and other accessories and hardware products.
H beam is widely used in all kinds of civil and industrial building structures , all kinds of large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high temperature working conditions, large bridges with large bearings capacity, good cross-section stability and large span are required, heavy equipment , expressway, shipframe, mine support, foundation treatment and dam works, various machine components.
