How to identify the quality of broken bridge aluminum
Inferior broken bridge aluminum profile products, shoddy manufacturing, will greatly affect the overall relationship, and will also have an impact on human health. How to identify the quality of broken bridge aluminum profiles? The following 3 points are shared, and Retop Aluminum will lead everyone to learn together!
1. Observe the surface of the profile
Whether the quality is good or not, the surface of the aluminum alloy profile of the broken bridge can be seen. Generally, the surface of the aluminum profile of the broken bridge has a luster and texture. The color sprayed on the surface is also handled very naturally, and it looks very smooth in the past. If the broken bridge aluminum profile is of inferior quality, the surface will definitely be smooth and rough, and the color will not look natural. After a period of use, the sprayed color will change color and become less beautiful and full.
2. Sectional structure of profiles
The geometric angle of the good broken bridge aluminum profile after the cut surface is very precise, and there will be no bending or twisting. It looks very positive and its thickness is appropriate.
3. Observe the thermal insulation strip of the profile
Insulation strips are divided into imported and domestic ones. Most of the insulation strips produced in China are made of plastic PVC, and the imported ones are polyamide, that is, nylon insulation strips. Therefore, the good broken bridge aluminum profile is imported, because it is more cost-effective, not only achieves the effect of thermal insulation, environmental protection and energy saving, but also saves 20-30% of energy.
