History of Prepainted Steel Sheet
The production of prepainted steel sheet originated in the United States in the mid-1930s. In the beginning,
the technology was only adopted in producing a prepainted steel strip.
Till 1995, the first batch of coating equipment for broad strip steel invent and produce in the United States in 1955.
In the 1960s, the production of prepainted steel sheets made rapid development in the United States, Europe, and Japan. Besides,
prepainted steel products also developed greatly all over the world.
By the end of the 1980s, the production of prepainted steel sheet in China had been almost blank.
Until the 1980s, Wusteel and Baosteel established the double coating double baking production lines of prepainted steel sheets in succession.
With increasing promotion and application of Baosteel’s prepainted steel sheets at home, more and more people make themselves acquainted with the production of steel sheets.
Thus, at the turning point of the 20th century the 21st century, a lot of production lines of prepainted steel sheets emerged
like bamboo shoots after a spring rain and there was also a great demand for such products.
The domestic annual consumption of prepainted steel is about 5.8 million tons according to the incomplete statistics.
