The quality of the surface of the product. 

The quality of the surface of the doors and windows will directly affect the overall installation effect, therefore, when choose and buy, attention should be paid that there should be no obvious damages on the decoration surface of doors and windows, shaded surface of adjacent components should not have clear aberration, and there should be no aluminum skimmings, burr, oil stains or other stains, etc on the doors and windows.

The sealing performance of the products.　

When choosing aluminum alloy door with mosaic glass window, sealing performance of which must be paid attention to. If sealing performance is not good, it will lead to dirtiness of insulating layer, affecting beautiful outlook. And products with high-quality sealing strip can prevent internal and external medium (water, air, dust, etc.) from leak or invasion, prevent or reduce the damage due to mechanical vibration and impact, so as to achieve functions like sealing, sound insulation, heat insulation and shock absorption, etc. In addition to using the sealing strip and wool top to seal, filling the double sheet glass with nitrogen gas can also prevent water vapor from entering.

Process of products.

For aluminum alloy doors and windows of high quality, processing is fine, component connection is firm, especially some patchwork parts are very smooth. However, for inferior aluminum alloy doors, aluminous profile series and norms are chosen blindly, processed in a rough way, positions such as frame and corner are not smooth stitching, and sometimes there even appear large gaps. Accordingly, when consumers choose and buy, should pay special attention to checking the presence of defects, large cracks, and so on and so forth. Moreover, all of the aluminum alloy doors and windows products will have an acceptable range of size deviation, and the better the processing technology of enterprise, the smaller size deviation of the products, and the smaller the better.
