The current market policy management system of aluminum alloy doors and windows is not perfect, resulting in uneven quality of aluminum alloy doors and windows in the market. How should consumers cultivate a pair of insight to identify the quality of aluminum alloy doors and windows?
1. Look at the price. Price can be used as a reference factor, but not a decisive factor. At present, the main components of commodity sales price are cost and material price, processing price and profit. When the profit income is equal, the sales price of high-quality goods will rise accordingly.
2. It depends on the materials. At present, the raw material used by the general manufacturers is the cooked aluminum with a content of more than 98%, which is soft in nature and can be rolled or rolled in a variety of shapes. However, the raw aluminum is less than 98%, which is brittle and hard, so it can only be used for casting goods. In order to reduce the production cost, some manufacturers will mix some miscellaneous aluminum and waste aluminum in their products, so the corrosion resistance of aluminum alloy doors and windows is not enough and the time is long Doors and windows will deform.
3. The quality of aluminum alloy doors and windows is also reflected in its surface processing. If it is a high-quality product, the surface will not have obvious damage or the window will not have obvious dents. In addition, high quality doors and windows will not produce obvious color difference. There should be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there should be no adhesive overflow at the assembly joints
4. Looking at brands, many people say that I don't know what kind of products to buy. For those people who don't know the knowledge of doors and windows, they can buy brands because the brands that can survive in the historical round of elimination and occupy a certain market share have certain basic strength and technical support. The quality of such products and after-sales are guaranteed, but when you buy, you should see the brand logo clearly and distinguish the difference between counterfeit and genuine products.
5. Finally, you can see whether the color difference between the doors and windows frames is obvious, and the poor quality doors and windows will have obvious color difference.
