The development history of color-coated galvanized steel coil
After the color-coated galvanized steel coil was introduced in the United States in 1936, the first application in construction was the movable shutters, weatherboards and other parts. The raw material is also sheet or 2-inch wide continuous coated steel coils produced by Amcor Steel and Hutt Engineering in the United States.
The United Kingdom also began producing color-coated steel sheets in 1961. Subsequently, developed countries in the world such as Germany, Sweden, etc. also began to mass-produce color-coated steel plates, which are also mainly used for construction purposes.
In the 1970s, some countries or regions in Asia (South Korea, the Philippines, Taiwan) began to have continuous color-coated steel plate production lines.
In the 1980s, emerging economies represented by China began to develop or introduce color-coated steel plate production equipment. During the Sixth Five-Year Plan period, the State Planning Commission and the Science and Technology Commission organized the three ministries of metallurgy, chemical industry and light industry to include the development of color coating in the national development plan. Subsequently, Baosteel and Wuhan Iron and Steel introduced foreign color-coated steel plate production lines. After 1995, the demand for color-coated steel plates in China rose rapidly, driving domestic private enterprises to invest heavily in color-coated production lines and import a large number of color-coated steel plates from South Korea and Taiwan. , so that the production capacity of China's domestic color coating, which can exceed 20 million tons / year.
