With the rapid development of China’s automobile industry, the amount of hot-dip galvanized steel sheets for automobiles has also risen sharply. Although several large-scale steel conglomerates in China have completed or closed to completing their technological progress from steelmaking to cold rolling, a number of production lines have been introduced the production of high-grade galvanized steel panels for automobiles, with the ability to produce high-grade automotive steel plates. It is ripe for China to develop its own galvanized sheet for automobiles. However, so far, the production scale and product quality limitations of domestic hot-dip galvanized sheet can not fully meet the requirements of China’s automobile industry. Due to a single product positioning unit, foreign has been widely used in many high-grade automotive galvanized sheet varieties. The current introduction of the production of automotive galvanized sheet unit still can not produce, China’s auto industry is still a large number of imported hot-dip galvanized.
