The existing varieties of a single galvanized aluminum, only a small number of alloying plate, far from meeting market demand.
Hot-dip galvanized steel strip has been a shortage of varieties in China's market. Since the mid-1990s, about 800,000-1,000,000 tons have been imported from abroad every year. With the development of the domestic economy, especially the development of automobiles, home appliances and construction industry, the demand for galvanized steel strip has increased greatly. China in the past two decades has built a number of annual output of more than 100,000t production line, but from the process, equipment composition to the product varieties belong to the low level of traditional technology hot-dip galvanizing unit, in the variety of quality and quantity can not meet the needs of China's economic construction and development, it is still necessary to build a new hot-dip galvanizing line to meet the needs of the market.
Since the 1990s China's galvanized steel production has made great progress, the domestic has and under construction galvanized aluminum processing capacity of nearly 3 million tons. In recent years, the market share of domestic galvanized aluminum plate increased very quickly, from about 27% in 1996 to about 59% in 1998. The main domestic manufacturers for the Baosteel, Wuhan Iron and Steel, Panzhuang Steel, Handan Iron and Steel and other five enterprises have a total production capacity of more than 1.3 million tons.
China's existing hot-dip galvanizing unit and foreign advanced level there is a major gap between the vast majority of units do not have pre-cleaning equipment, the existing light machine are relatively simple two-roll light machine (Pangangang for four-roll), can not better improve the mechanical properties of the strip, especially deep-drawn performance; the existing varieties of a single galvanized aluminum, only a small number of alloying plate, far from meeting market demand.
China's manufacturers produce hot-dip galvanized steel are building materials, light industry, agriculture, transportation and other industries as the main users. Due to the existing hot-dip galvanizing equipment conditions, process technology and the original plate performance limitations, the actual production of automotive manufacturing industry can be used for galvanized aluminum sheet is very little.
Characteristics of galvanized steel: galvanized can effectively prevent and control steel corrosion, to extend the service life. Galvanized thin steel (thickness of 0.4 ~ 1.2mm ) also known as galvanized iron, commonly known as white iron. Galvanized steel is widely used in construction, vehicles, home appliances, daily necessities and other industries.
