Production status of steel coil

The low cost hot dip galvanized steel coil factory has been very good in China. Since the mid-1990s, it has imported about 800,000 to 1 million tons from abroad every year. As the development of the domestic economy, especially the development of the car, home appliance and BLDG. In recent 20 years has built a batch of annual production capacity of 100000 tons production line, but from the process flow, equipment composition to the varieties of products belong to a low level of the traditional technology of hot galvanizing units, on the varieties of quality quantity cannot meet the demand of the development of economy in China, still need to build new hot galvanizing line to meet the needs of the market.

Since the 1990s, China’s galvanized steel coil production has made great progress, domestic and under construction aluminum zinc steel coil processing capacity reached nearly 3 million t. In recent years, the market share of domestic galvanized aluminum coil increased rapidly, from about 27% in 1996 to about 59% in 1998.

The main difference between China’s existing hot galvanizing units and foreign advanced level lies in that most units do not have pre-cleaning equipment, which is difficult to guarantee the quality of the galvanized surface. The existing finishing machine is a relatively simple two-roll finishing machine, can not better improve the mechanical properties of the coil, especially deep drawing performance; Existing varieties are single aluminum zinc steel coil in stock, only a small amount of alloying volume, far from meeting the market needs.

The hot dip galvanized steel coil produced by our manufacturers are mainly used in building materials, light industry, agriculture, transportation, and other industries. Due to the limitation of the existing hot-dip galvanizing equipment, process technology and the performance of the original coil, the actual production of a galvanized aluminum coil for the automobile manufacturing industry is very few.

Galvanized steel coil features: galvanized steel can effectively prevent corrosion, extend the service life. Galvanized sheet steel coil (thickness of 0.4 ~ 1.2mm), also known as a galvanized iron sheet, commonly known as a galvanized iron sheet. The galvanized steel coil is widely used in construction, vehicles, home appliances, daily necessities, and other industries.
