[China Aluminum Network] The main choice for aluminum ceilings is to look at their raw materials, not to concentrate on their thickness. According to the principle of planning, general home improvement strip thickness can reach 0.5mm, 0.6mm can be, very few to 0.8mm, why is it because of the use of aluminum alloy raw materials, do not have to be thick enough, and then The span of home improvement bars will not be very large, and there is no need to use such a thick one.
Top of the list look at the windows and doors. The aluminum profile, thickness, strength and oxide film used for high-quality aluminum alloy doors and windows are all in line with the relevant national regulatory rules. The wall thickness should be 1.2mm or more, and the thickness of the oxide film should reach 10 microns. If you go beyond national norms, or even reach European norms, of course, it is a better choice.
The second look at the processing of doors and windows. High-quality aluminum alloy doors and windows, precision processing, sophisticated devices, good sealing function, switch freely. Defective aluminum alloy doors and windows, data and specifications are not up to standard, and the processing is uneven, poor sealing, not only leakage of air leakage, and in the case of strong winds and external forces, the simple presentation of the glass splitting, etc. The appearance of the composition glass scratches or falls.
The third look at the appearance of doors and windows. The appearance of doors and windows is also a key link. Aluminum alloy doors and windows have an artificial oxide film and are colored to form a composite film. This composite film is not only corrosion-resistant, wear-resistant, but also has a certain fire protection function. The gloss is extremely high. When comparing as much as possible, try to choose the specifications of the aluminum alloy doors and windows manufacturers of goods, choose to process precision, accurate, open and close light and sensitive, no noise, and elegant decoration of goods.
The fourth look at the price of doors and windows. Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, quotes than aluminum alloy doors and windows are about 30% higher. Some aluminum alloy doors and windows with a thickness of 0.6-0.8 mm aluminum profile, the tensile strength and yield strength are much lower than the relevant national regulatory rules, the application is very unsafe, and must not be ignored because of the cheap and ignore its own safety factors. .
The fifth look at the function of doors and windows. Aluminum alloy doors and windows generally check the following main features: strength, air tightness, watertightness, opening and closing force, sound insulation, heat insulation, nylon guide wheel durability, open and close lock durability and other elements.
