The Director of the Plastics Window and Door Committee of the China Metal Structure Association pointed out that it is expected that in 2000, China’s plastic window and door market will experience oversupply in some areas. According to the Ninth Five-Year Plan for Chemical Building Materials and the 2010 Development Goals, by 2000, when the average market share of plastic doors and windows reaches 15%, about 300,000 tons of profiles will be required, but now the production capacity far exceeds this number. In recent years, the development of plastic steel doors and windows in China is also very fast, and steel doors and windows in Beijing, Shanghai, Shandong and Northeast China and other places.
