[China Aluminum] In the daily consumption process, we all tend to have such a consumption concept: the higher the price, the better, the greater the quantity, the better, the more solid the material, the better... Because the more materials are consumed, the corresponding price will be The higher the quality, the better the quality will naturally be. Is this view correct? In fact, this is not the case! Usually the price of aluminum alloy doors and windows constitutes three elements: profiles, window types, accessories. The wall thickness of profiles does have a large impact on the price of products. Many consumers will take it for granted that aluminum alloy doors and windows will be taken for granted. The thicker the aluminum wall thickness, the more the national standards, the better the product quality. In fact, this view is one-sided. The national standard for wall thickness of aluminum alloy doors and windows products is set in accordance with the requirements of energy conservation and environmental protection in terms of ensuring product safety and performance. The thicker the wall thickness of product profiles is, the better the product quality is. Because of the thick wall thickness of the profile, it cannot guarantee the airtightness and watertightness of the product. It will not guarantee the high quality of the product. Three aspects judging the advantages and disadvantages of aluminum alloy doors and windows 1. The rationality of the design of the profiles; 2. Hermeticity and watertightness of the product; 3. The product's glass, hardware and accessories configuration. If a product's profile design is unreasonable, and airtightness and watertightness do not meet the requirements, even if its wall thickness is more than N times the national standard, it is not a good product. Excessive pursuit of aluminum alloy wall thickness will not only result in serious waste of resources, but will also lead to additional price increases, which will bring unnecessary economic burden to consumers. The aluminum profiles used in high-quality aluminum alloy doors and windows, their thickness, strength and oxide film can generally meet the national standards, such as the relevant national requirements: 1. The aluminum wall thickness of aluminum alloy doors and windows should be no less than 1.2mm, and the thickness of oxide film should reach 10 microns. 2, tempered glass is better than ordinary glass, if the security of doors and windows and durability can be considered. 3, stainless steel hardware accessories (such as screws, hinges, etc.) than aluminum accessories. 4. It is better to choose the stainless steel material for the pulley, so that the strength and wear resistance are higher. The push-pull is durable and not easy to be damaged.
