The aluminum windows and doors have brought a new generation to the metal windows and doors in China. In the late 1970s, the technology of aluminum windows and doors profiles was introduced from Europe, America, and Japan and developed into a new step in 1980s. Most of time we referred to the shapes of Japanese aluminum windows profiles because the location and climate of Japan is similar those in China, and Japan got the high production technology and economic condition. And about the professional production machines, they introduced from Germany and other countries in Europe. During those 30 years, the aluminum windows and doors profiles have gone through three phrases, and now are stepping into the fourth phrase.
Phase One: From 1983 to 1993, we introduced the processing equipment and production as well as production machines of aluminum profiles. And the 90 sliding doors and windows series and 70 sliding doors and windows series and 38 casement doors and windows were the main products. They were high profit with low technology level. But the production capacity is limited by the national policy. Thus this phase was marked by “imitation and being limited”.
Phase Two: From 1994 to 2000, in this phase, the demand of aluminum windows profiles grew rapidly. However, lacking of technical innovation, the quality of products was not so good. Thus it was marked by “absorption and increment”.
Phrase Three: From 2001 to now, the production of the aluminum windows and doors profiles structure is adjusted and optimized. And more advanced technology is introduced from foreign countries (mainly from Italy and Germany). Technical innovation becomes popular. A lot of enterprises have got their own self-developed products. And the quality can reach the international advanced level. The aluminum doors and windows are in sustainable development. Thus this phase is marked by “introduction, creation and expansion”.
Phase Four: From now on, the aluminum doors and windows profiles are stepping into a new age, all of the aluminum doors and windows profiles become systematized with other aluminum building products. Take all of the aluminum building products as a unity, to design a perfect organic combination to satisfy people’s requirements of having a safe, comfortable, energy-efficient, economical and environmental house.
