With the development of society, people's life is becoming more and more abundant, and they are more and more strong in brand. There is a kind of consumption concept of commodities: the more expensive the goods are, the better the brand is Because the commodity is expensive, the material will be good, the quality will be good. Like aluminum alloy doors and windows, is the more expensive the better? The more famous the brand, the better? Is the thicker the profile, the better? Is that correct?
Generally, the price of aluminum alloy doors and windows has three elements: profile, window type and accessories. Among them, the wall thickness of profiles has a great impact on the price of products. When purchasing aluminum alloy doors and windows, many consumers will of course think that the better the wall thickness of aluminum profile is, or even exceeds the national standard, the better the product quality will be. In fact, this is not the case.
The national standard for the wall thickness of aluminum alloy door and window products is set according to the requirements of energy conservation and environmental protection under the condition of ensuring product safety and performance. It is not that the better the wall thickness is, the better the product quality is. Because too thick profile wall thickness can not guarantee the air tightness and water tightness of the product, and the product quality is high.
In order to judge the quality of an aluminum alloy door and window product, we must comprehensively consider the following aspects:
1. The rationality of profile design;
2. Air tightness and water tightness of products;
3. Products of glass, hardware and accessories configuration.
If the profile design of an aluminum alloy door and window product is not reasonable, and the air tightness and water tightness can not meet the requirements, even if its wall thickness is more than n times of the national standard, it is not a good product. And excessive pursuit of aluminum alloy profile wall thickness is bound to bring serious waste of resources. Too thick profile will bring high product price to consumers and bring unnecessary economic burden.
The thickness, strength and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows can generally meet the national standards, such as the relevant national requirements:
1. The wall thickness of aluminum profile of bridge broken aluminum alloy doors and windows shall not be less than 1.4mm and above, and the thickness of oxide film shall be 10 μ M.
2. If the safety and durability of doors and windows are considered, tempered glass is better than ordinary glass.
3. Stainless steel hardware accessories (such as screws, hinges, etc.) are better than aluminum parts.
