The development of PVC profiles in China

PVC profile products have experienced an introduction period and a period of rapid development, which can be defined from the 1980s to the mid-1990s and from 1995 to 2002 respectively. After 2003, the PVC profile industry entered a period of transformation. During the introduction period of the product: manufacturers generally pursued low cost, simplified the cross-sections of door and window profiles, and filled the formula with a large amount of calcium carbonate, resulting in low product performance and the emergence of many quality problems that affected the promotion of the product.

Development history of PVC profiles in China.

Beginning in 1995, a group of powerful companies began to absorb the technical essence of foreign European profiles and develop their own series of doors and windows, becoming the leading domestic plastic doors and windows, promoting the technological update and development of doors and windows, and bringing unprecedented progress to the entire industry. development and rapid growth. After entering the product maturity period, that is, starting from 2003, many shortcomings began to be reflected. Excessive profit margins led to excessive blind investment, making the industry's comprehensive production capacity nearly 3 million tons, much higher than market demand; many new investments Instead of starting with product innovation and technological innovation, they simply imitate, even cut corners, and engage in counterfeiting. The industry market competition is in an unhealthy state. The continuous rise in raw material market prices has intensified this unhealthy competition, putting some companies in a difficult situation and suspending or semi-stopping production.

Current status of PVC profile industry

This industry also has the contradictions of a large number of manufacturing companies (nearly 400), small output and large production capacity (2.8 million tons), small demand (national profile sales of 1.2 million tons in 2003), and insufficient production capacity. The annual output exceeds There are less than 10 companies producing 20,000 tons. Product quality levels vary. There is still a market for inferior products. The industry’s quality and technical standards are too low, which is not conducive to technological progress and has led to the comeback of substitute aluminum materials. The high-end market (30%) is occupied by foreign brands, while the mid- to low-end market is unprofitable and highly competitive, and the final pattern has not yet been formed.

From the perspective of factory distribution, among the 392 profile manufacturers, 37% are in the southeast region, 12% in Shandong, 17% in the central region, 19% in the northeast, and 15% in the west. Looking at the production capacity segment, the national production capacity in 2003 was 2.8 million tons, with 9% in Shandong, 1% in the central region, 32% in the northeast, 7% in the west, and 39% in the southeast.
