Door and window aluminum wall thickness knowledge
[China Aluminum] In our daily consumption, I believe that many people believe that: the higher the price of goods, the better, the greater the number, the better, the thicker the material, the better... Because the more materials are consumed, the price is accordingly. The higher the quality, the more natural it is. So is this understanding right?
The thickness of aluminum alloy doors and windows products is not selected according to the specification of smaller wall thickness, but selected according to the requirements of the size of doors and windows, the wind pressure value and the design of doors and windows air tightness, watertightness and other requirements. In the case of ensuring product safety, performance, environmental protection and other requirements, it is not the thicker the thickness of the door and window profile, the better the product quality.
Judging the quality of aluminum alloy doors and windows, we must start from the following points
1, whether the design of the profile is reasonable.
2. Whether the airtightness and watertightness of doors and windows are up to standard.
3. How to configure the hardware, glass, and accessories of doors and windows.
If a door and window, its profile design is not reasonable, watertightness and airtightness reach substandard, even if its wall thickness exceeds the national standard N times, it is not a good product. At the same time, excessive pursuit of the aluminum alloy wall thickness will inevitably bring unnecessary waste of resources to the country, and too thick profiles will inevitably lead to excessively high prices and give consumers unnecessary expenses.
High quality aluminum alloy doors and windows features
1 Aluminum
The aluminum used for aluminum alloy doors and windows has a smooth and glossy surface with no aluminum swarf, burr, etc. Its strength, thickness (≥1.4mm), and oxide film (≥10μm) must meet national standards. Small-size door and window manufacturers are in In the mixed market structure, there are many "thin materials" shoddy, suggesting that consumers choose reliable and well-known brand products.
2 glass
Toughened glass is obviously a better choice than ordinary glass. Strong impact resistance, not easily broken, even broken will be broken in the form of particles without sharp angles, greatly reducing the harm to the human body. At the same time, it has good thermal stability and the sound insulation effect of toughened insulating glass is better.
3 Hardware
The quality of hinges, door handles, locks, pulleys and other hardware accessories is the key to ensure the service life of aluminum alloy doors. The use of stainless steel hardware, bright color, no rust, scratches and other phenomena, the more important is to use a reliable brand of hardware, big brands of hardware and profiles will be engraved with the brand LOGO.
4 Process
Good aluminum alloy door and window products have fine processing, smooth tangent lines and accurate angles, and no obvious gaps will appear during the splicing process. The sealing performance is good and the switch is smooth. If the processing is unqualified, there will be sealing problems. Not only air leakage but also strong wind and external force will cause the glass to burst and fall off.
5 auxiliary accessories
Sealing strips and wool strips are important accessories for guaranteeing aluminum alloy doors, especially hollow doors. The sealing strip must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, and the section structure size must match with the aluminum door profile. Tops need to be sealed, waterproof, dense and dustproof.
