China's doors and Windows hardware manufacturing enterprises from the southeast coastal areas began to develop, mainly concentrated in Guangdong, Zhejiang, Shandong and other places. At the present stage, enterprises in Guangdong, Zhejiang, Shandong and other places still maintain the market leading advantage and have strong competitiveness. Affected by the level of economic development and climatic conditions, various regions have great differences in the demand for doors and Windows.
At present domestic economy developed area and area south of Yellow River, climate is inclined hot, use door window hardware mostly. As a result of the requirement of energy conservation policy, in high-grade real estate USES heat insulation broken bridge aluminum doors and Windows, have the effect of energy conservation and heat preservation. In northeast, northwest, north China cold cold area basically USES plastic door window. Solid mu Fu is mixed door window, aluminous mu Fu is mixed door window basically is concentrated in economy developed area, be like the high-grade building property of the place such as Beijing, Shanghai. The door window profile that USES is different, the class that locates is different, the kind of door window hardware fittings that each area needs, class is different also.
Doors and Windows as the building envelope, its energy-saving performance directly affects the building energy conservation, and doors and Windows hardware as the doors and Windows in the annex, in providing a complete set for doors and Windows, its pros and cons directly affect the energy-saving effect of doors and Windows, therefore, high quality Windows and Windows hardware in the building energy conservation play an important role. At present, the low-end market is shifting to the middle and high-end market, and the proportion of the middle and high-end market is increasing year by year. With the passage of time, the market share of the middle and high-end market will become larger and larger in the future.
