In 1995, Dalian Shide Group became one of the early adopters of plastic steel profiles for doors in China, marking the beginning of large-scale production of this material in the country. Today, China's annual production capacity for plastic steel profiles has reached as high as 5 million tons. However, this rapid growth has led to overproduction and intense competition among similar products. The market is dominated by a few major players, with Wuhu Conch Profile Co., Ltd. being the largest producer, followed closely by Dalian Shide, Zhejiang Zhongcai, Hebei Baoding Baoshuo, Shandong Jinda Shuangpeng, and Shanxi Zhongde.
The national standard for plastic steel profiles in China is GB/T 8814-2004, which serves as a reference for many manufacturers, including those that have received national exemptions. Unlike the diverse range of profiles found in Europe and the United States, the Chinese market primarily offers a limited selection. The most commonly used profiles are 60mm flat door and window profiles, as well as 80mm sliding door and window profiles. These two types account for more than 80% of the total consumption in the market, highlighting the lack of variety and the dominance of standardized products.
Despite the widespread use of plastic steel profiles, challenges such as low differentiation, price wars, and environmental concerns remain significant issues. As the industry continues to evolve, there is a growing need for innovation, quality improvement, and sustainable development to meet both domestic and international demands.
