Beijing PVC doors and windows product quality basic profiles
In recent years the market for Overview 2006 Beijing residential window market remains total imbalance in the situation of supply exceeding demand. As plastic window slow technological progress, and take low-grade line, although prices are low, but the use of PVC doors and windows are still fell, breaking cold (heat) Bridge increased amount of aluminum alloy doors and windows, color steel plate glass windows and doors and windows and doors market share Relatively small.

PVC window of the main product varieties are: Series 58, Series 60, Series 70, Series 80, Series 85, 88, 95 series. Main technical equipment are: First, since 1998, Beijing Jia Suite, the new North Plastics Group, Beijing Bowei letter three Swiss companies, Beijing Longtai companies such as China and Germany have doors and windows from Germany Wei Gema, the EU-peng, Harvard The company procurement package 10 NC Sawing Center, NC welding centres, CNC machining equipment, such as the international community in the 1990s the level of PVC doors and windows automated production lines.

2002 Beijing the capital of infertility Door to complete the domestic production of the highest allocation of PVC doors and windows automated production line (Germany Yale) the installation and debugging operation. The technological level of the equipment Habitat domestic industry PVC doors and windows in the forefront. Second, the domestic PVC doors and windows assembly equipment for processing the largest percentage, 97 percent. Shandong bright plastic window by the main machinery company, Shandong Tianchen plastic window machinery company, Shandong good plastic window German machine company, the Beijing Aviation Institute of Technology, Beijing Equipment Corporation, and other peaceful production of more than 100, local assembly equipment has been gradual transition to the stage of imitation to the design stage, the beginning of 2001 the company produced 2.60 bright NC NC cutting and welding centres of higher degree of automation, such as processing equipment, is near Similar equipment abroad, the same production capacity of domestic equipment for the price of imported equipment of the 1 / 4µ½1 / 5. PVC doors and windows hardware accessories mainly from Guangdong Kinpo Group, Hualong company in Xinxiang of Henan, Shandong State Nearly 100 companies, and other ancillary . North new plastic PVC doors and windows Group hardware accessories production has just started, the 2001 production of 120 million yuan investment in high-end transmission lock, bailiffs hand, and other products. In each market prices between 160 to 200 yuan. Germany Noto, Georgia estate companies, Sijiliya major companies supporting high-grade plastic PVC window, the market set prices between 220 to 350 yuan, in recent years, sales gradually increased.

Beijing PVC profiles market total of about 30,000 tons, the Beijing production capacity of PVC low profile this year, production is about 10,000 tons, the market gaps higher profile, some of the major market vacancies from the field conch, LG, Jinpeng, etc. Company manufacturers to fill.
 
PVC doors and windows section profiles the basic structure for the European form of imitation, but the profile thin wall thickness, cross-section of small, is economic. In recent years, the domestic development of multi-chamber structure of the original profiles breakthrough single-chamber structure design, acoustic insulation performance has been enhanced, also brought to install enhanced small steel chamber space, with the production of material processing The windows, the moment of inertia of its components lower, thus limiting the value of higher air pressure in the basic areas and high-rise building on the scope of use.

2006 Beijing civilian residential windows remained as the main PVC doors and windows, aluminum doors and windows, followed by the market. PVC doors and windows account for about 60 percent of market share. The city's doors and windows in the building production and processing enterprises of 650, capacity: 15 million square meters / year (including PVC doors and windows, aluminum doors and windows, glass doors and windows and other steel ), Together with provinces and cities outside the doors and windows Beijing enterprises diverted 10 percent market share, building doors and windows serious imbalance between production and demand market. The past four years, PVC window unit prices on the whole a declining trend, its causes are: first, PVC window space industry profits larger, social idle funds have invested windows and doors industry, doors and windows from 200 processing enterprises to expand 650, with the strength of the participation of large enterprises and promote the industry's development and progress, at the same time, bring space industry profits gradually become smaller, lower prices. Second, a considerable part of the doors and windows to maintain its own corporate profits, lower material costs and compete unit processing costs, procurement of low-quality low-cost hardware and accessories, not the manufacturing process standards organizations. Sometimes, between enterprises for an order to take each otherѹ¼Û, Dianzi increase the proportion of the disorderly way, vicious competition, product quality and function of serious landslides, customer complaints on the rise. Some larger scale, equipment and good quality and good reputation of enterprises, reduced orders, underemployment. Their production and business activities into this predicament, financial situation deteriorate, senior management personnel and technical backbone of a serious loss of enterprises suffering.
