Product Specification: 0.14-1.8mm x 900-1250mm

Two 1450mm hot-dip galvanizing (aluminium) production lines have the functions of annealing reduction, galvanizing, finishing, stretching and straightening, passivation, and can produce 900-1250mm steel bandwidth. 1 # galvanizing line is specially designed for galvanizing with thickness of 0.14-1.8 mm and single-sided galvanizing layer thickness of 20-140 g/. 2 # Aluminum-zinc plating line can be plated with 5%, 15%, 25% and 55% Aluminum-zinc, and the thickness of Aluminum-zinc coating can be 17-35 g/. The annual output of the two lines is 500,000 tons.

The product has excellent shape, surface quality and meets the mechanical performance requirements of users. Widely used in household appliances, construction, automobile and other fields.

In recent years, China's galvanized sheet production has increased year by year, while imports have also increased year by year, the growth rate is even higher than that of production; after deducting repeated production statistics, the consumption of galvanized sheet is about 5.27 million tons. After 1999, the import of galvanized sheet exceeded the production for the first time. The self-sufficiency rate of domestic products was less than 50%, and the trend was decreasing year by year.

In recent years, the increase of domestic production of galvanized sheet is mainly due to the increase of production of hot-dip galvanized sheet. In 1998-2002, the production of hot-dip galvanized sheet increased from 970,000 tons to 2.2 million tons, while the import increased faster, from 370,000 tons in 1998 to 1.56 million tons in 2002, and the apparent consumption increased from 1.32 million tons to 3.67 million tons. In 2002, the domestic product self-sufficiency rate of hot-dip galvanized sheet was about 60%. In that year, the domestic production and import of hot-dip galvanized sheet increased compared with the previous year. Especially, the import increased more greatly. The main reason was that the demand for thin-gauge hot-dip galvanized sheet for color-coated sheet production increased, which led to a decrease in the domestic product self-sufficiency rate.
