In our daily consumption, I believe many people believe that the higher the price of the goods, the better the price, the more the quantity the better, the thicker the material, the better, because the more materials consumed, the higher the price and the quality Needless to say. So, is this understanding correct? The thickness of
aluminum alloy doors and windows is not selected according to the minimum wall thickness of the specification, but the water tightness of the design doors and windows is selected according to the size of the door and window hole, the wind pressure value and the air tightness. In the case of ensuring product safety, performance and environmental protection, it is not that the thicker the wall thickness of the door and window profiles, the better the product quality. To judge the quality of aluminum alloy doors and windows, you must start with the following points: 1. Whether the profile design is reasonable. 2. Whether the air tightness and water tightness of doors and windows meet the standards. 3. What is the configuration of hardware, glass and accessories for doors and windows? If the contour design of doors and windows is unreasonable, the water tightness and air tightness do not meet the standards, even if the wall thickness exceeds N times the national standard, it is not a good product. At the same time, excessive pursuit of aluminum alloy profile wall thickness will inevitably bring unnecessary waste of resources to the country, while excessively thick profiles will inevitably lead to excessive prices and unnecessary consumer expenditures. The characteristics of high-quality aluminum alloy doors and windows 1. The raw material aluminum is used for high-quality aluminum alloy doors and windows. The aluminum surface is smooth and shiny, without aluminum chips, burrs, etc. Its strength, thickness (≥1.2mm) and oxide film (≥10) microns) must meet national standards. The market structure of small door and window manufacturers is uneven. There are many 'fake and shoddy' 'thin materials'. Consumers are advised to choose reliable and well-known brand products. 2. Compared with ordinary glass, the raw material glass, tempered glass is obviously a better choice. It has strong impact resistance and is not easy to break. Even if it breaks, it will be broken in the form of particles without acute angles, thereby greatly reducing the harm to the human body. At the same time, it has good thermal stability and better sound insulation. 3. The quality of raw materials, hardware accessories such as hinges, door handles, locks, pulleys and other hardware accessories is the key to ensuring the service life of aluminum alloy doors. Use stainless steel hardware, bright colors, no rust, no scratches, etc. The most important thing is to use reliable brand hardware. The hardware and configuration files of major brands will be engraved with the brand LOGO. 4. Auxiliary accessories, sealing strips and wool strips are important parts to ensure aluminum alloy doors, especially hollow doors. The sealing strip must have sufficient tensile strength, good elasticity, good heat resistance and aging resistance, and the size of the cross-sectional structure must match the outline of the aluminum door. The top needs to have good sealing performance, good waterproof performance and dense dustproof performance. 5. Process and performance Aluminum alloy doors and windows have good quality, fine processing, smooth tangent, accurate angle, no obvious gaps in the splicing process, good sealing performance, and smooth opening and closing. If the processing is not qualified, there will be sealing problems, not only the leakage of wind and rain, but also the glass is easy to break and fall under the action of strong wind and external force.
