Contemporary building door window presses type of profile can be divided roughly: window of window of plastic window, compound material, aluminium alloy, among them window of aluminium alloy is the product of main building door window of our country nowadays, hold in current building quite large proportion. In fact, no matter from the performance such as wind pressure, water tightness, air tightness or from environmental protection respect, aluminum alloy window has its superiority. This is because compared with plastic Windows of the same section, the moment of inertia of aluminum alloy Windows is 3-4 times that of plastic Windows; With the use of heat insulation broken bridge in aluminum alloy profiles, the heat preservation and heat insulation performance of aluminum alloy Windows are greatly improved, which is very suitable for the energy-saving requirements vigorously advocated nowadays.

Aluminum alloy doors and Windows hardware fittings is an important part of its performance and quality of doors and Windows function has an important impact. As a result of contemporary technology unceasing development, fittings of door window hardware (shake handshandle, armrest, hinge, slippery course, join), more and more ground also infuse into the market. The shape and color of these products, multifarious, beautiful things in eyes, make the practicality of doors and Windows and the appearance of many. But as a result of spare parts material and surface adornment layer material is different, their service life (basically point to the corrosion resistance, durability and strength) differ very far, although colour and lustre is same, even feel also similar aluminum alloy window fittings its gap can reach several times and even tens of times. Aluminum alloy doors and Windows hardware in addition to consider must have enough mechanical strength, but also pay attention to the selection of materials and aluminum alloy contact use, can maintain good corrosion resistance. Whether the hardware of aluminum alloy doors and Windows can meet the requirements of design life is very important to the safety and durability of aluminum alloy doors and Windows in the process of use. Only by combining the two can the characteristics of aluminum alloy doors and Windows be beautiful and generous and durable.
