UPVC Window Reinforced profiles

Plastic window is a form of window that is actively promoted by the state in the mid-1990s after the wood, iron and aluminum windows. Because of its low price, performance and price is better, is still widely used. This window is made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., is the most commonly used window type of modern architecture one.

Plastic doors and windows are made of polyvinyl chloride (PolyVinyl Chloride, often referred to as PVC) resin as the main raw material, plus a certain percentage of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion molding, and then Through the cutting, welding or screw way made of doors and windows frame fan, equipped with sealing tape, tops, hardware, etc., at the same time to enhance the rigidity of the profile, more than a certain length of the cavity needs to fill the steel lining Tendons), so made of portal windows, called steel doors and windows. So the overall price of plastic steel windows than other types of plastic steel window slightly expensive, and the introduction of steel doors and windows production process also has its unique process, plastic window construction program and other differences in many.

History of Development

Plastic window is the late fifties of this century, first developed by the West Germany, in 1959 began production. The original plastic windows are made of single plastic structure, relatively simple, rough, along with the 1972 global energy crisis, the early 1970s energy saving effect of the plastic window has been a lot of use, but also to promote the profile production technology, Performance is improving, from the original single-cavity profiles to the development of three-cavity, four-cavity profiles, but also led to the development of plastic doors and windows in Europe and Asia. According to incomplete statistics, the use of German doors and windows have accounted for 52% of the doors and windows market, Austria is 48%, Switzerland, Britain, France, Italy and other developed countries also have 10% -20%; US plastic window in the seventies The beginning of the use of the annual growth rate of 15% or more, the use of plastic windows in Asia, Japan, South Korea, Taiwan and Singapore, Thailand and so on.

China's plastic window started late, 70's production of calcium plastic doors and windows, quality, but off, has been basically eliminated. The real plastic window production from 1983 to start the introduction of equipment, when the technology is not very advanced, are single or two cavity cavity structure profiles, with the 91 industry improved, the domestic have emerged a number of extrusion equipment, mold , Profiles, assembly equipment and other manufacturers; 96 years with the country to vigorously promote and the newly formed the introduction of advanced equipment manufacturers in the birth of 90, greatly promoted the development of the industry. There are more than 2,000 domestic production lines, more than 400 profiles, more than 3,000 assembly plants, 99 tons of profiles production capacity of 800,000 tons, the annual capacity of 60 million square meters assembly, has become one of the few domestic development Rapid industry. Plastic doors and windows with its excellent performance is being accepted by the majority of users.
