Galvanized Steel Plate Production Status
Jun 13, 2018

The development of hot dip galvanizing production in China has been lagging behind. From the 1950s to the 1960s, 13 single-sheet flux hot-dip galvanizing units were built one after another with a capacity of 100,000 t/a, but due to low yield, high cost, poor quality, environmental pollution, and poor economic efficiency, Suspension and conversion. From the late 1970s, China began to build large-scale broadband hot-dip galvanizing units.

Hot-dip galvanized steel strips have been a scarce variety in the Chinese market. Since the mid-1990s, 80-100 million tons have been imported from abroad every year. With the development of the domestic economy, especially the development of automobiles, home appliances and construction, the demand for galvanized steel strips has also greatly increased. In the past two decades, China has built a number of production lines with an annual output of more than 100,000 tons, but from the process flow, equipment composition, and product variety, all belong to the low-level traditional technology of hot-dip galvanizing units, which cannot meet China’s quality and quantity requirements. With the demand for economic development, it is still necessary to build new hot-dip galvanizing lines to meet market needs.

Since the 1990s, the production of galvanized steel sheets in China has made considerable progress. The processing capacity of existing and under construction galvanized sheets in China has reached nearly 3 million tons. The market share of domestic galvanized sheets has increased rapidly, from about 27% in 1996 to about 59% in 1998. Major domestic manufacturers include Baosteel, Wuhan Iron and Steel, Panzhihua Iron and Steel, Handan Iron and Steel and Benxi Steel. The total production capacity of these five companies has exceeded 1.3 million tons.

The main gap between China's existing hot dip galvanizing units and foreign standards lies in the fact that the vast majority of the units do not have pre-cleaning equipment and it is difficult to guarantee the quality of galvanized surfaces; existing light-finishing machines are relatively simple two-roll finishing machines (climbing The steel is four-roll) and cannot improve the mechanical properties of the strip, especially the deep drawing properties; the existing varieties are all single galvanized plates, with only a small amount of alloyed plates, far from meeting the market needs.

China's manufacturers of hot-dip galvanized steel plates are mainly used in building materials, light industry, agriculture, transportation and other industries. Due to the limitations of existing hot dip galvanizing equipment conditions, process technology, and original plate properties, actual production of galvanized sheets for use in the automotive industry is rare.
