The modern building door & window hardware in China in developed in the twentieth century, however, the golden development age of China contemporary building windows and door is the two decades from 1981 to 2001. In the year 1911, steel doors and windows is introduced from foreign countries into China. In 1925, China's national industry started small batch production of steel doors and windows in Shanghai, and until the founding of new China, there are only more than 20 handicraft small workshop factories specializing in the manufacturing of door and window hardware. After the founding of new China, Shanghai, Beijing, Xi'an and other steel doors and windows enterprises built a large steel door and window production base, and since then, door and window hardware has been widely used in industrial buildings and some civil engineering. The 1980s was the heyday of the traditional steel doors and windows, the market share was 70% in 1989. Aluminum windows and doors is introduced into our country at the seventies, but they are only used in the foreign embassies and a few foreign works. With the in-depth development of the rectification of the national economy and success, aluminum windows and doors by the four species in the early eighties, eight series, the development of more than 40 varieties, more than 200 series, the formation of a more developed aluminum door & window hardware supplies gradually form a mature ands systematic system in most of the markets of mainland China. And at the same time it established the position of the pillar products. As we know that the wood doors are very different from the steel doors. It has been a long time plays a very important role in the building industry of China. Solid wood door, of its natural environment, no deformation, corrosion-resistant, crack-free and thermal insulation characteristics, is popular with many families. After the 1950s, the Chinese wooden doors supplier began to have a mass investment in this field, and it has greatly promote the rapid industrial development of China modern wooden doors. In the 1980s, at the same time learn from the different countries of solid wood suite door style and advanced production technology, people continue to explore traditional skills combined with their own national conditions folk, and gradually form a new generation of wooden doors style. Now, With the housing industry to accelerate the process and the doors of the consumer market, the development of small-scale production of the wood industry "custom" processing is gradually toward "standardized" direction, consumption patterns are changed too. Energy-saving Effect of Aluminum Windows & Doors Aluminum doors and windows profile is a combination of aluminum extrusions and thermoplastic hybrid materials insulation. The roll insulation aluminum is made by good insulation performance of high density polyamide PA66 strip or PVC rigid plastic strip, wearing a rolling process of aluminum fused. The aluminum of the foam insulation is the use of insulation, and the outer layer of aluminum connected embedded into one in the formation of insulating cavity filled with polyurethane foam, so that form the insulation aluminum "cold bridge", to achieve the insulation energy-saving effect.
