Color-coated aluminum sheet is mostly used in the construction industry, so its quality is particularly important. If you want to ensure the quality, you need to keep your eyes open when buying and be rigorous in all aspects of its purchase. Then its selection What are the buying skills? Let's get to know it together.
1. Look at the materials.
The thickness, strength and oxide film of aluminum profiles used in high-quality color-coated aluminum plates should meet the relevant national standards. The wall thickness should be 1.2 mm or more, the tensile strength should reach 157 Newtons per square meter, and the yield strength should reach per square meter. 108 Newtons per square millimeter, the oxide film thickness should reach 10 microns. If the above standards are not met, the doors and windows of poor quality aluminum alloy cannot be used.
Second, look at processing.
High-quality color-coated aluminum plate, fine processing, careful installation, good sealing performance, and easy switching. Inferior aluminum alloy doors and windows, blindly select aluminum profile series and specifications, processing in shoddy, sawing instead of milling, installation not as required, poor sealing performance, uncomfortable opening and closing, not only air leakage, glass explosion, but also In strong wind and external force, it is easy to scrape or knock the sliding part or glass off, destroying things and hurting people.
3. Look at the price.
In general, high-quality color-coated aluminum plates are about 30% more expensive than inferior aluminum alloy anti-skid plates because of high production costs. At present, there are many self-employed people who process color-coated aluminum plates, and they do not understand the structural characteristics and performance of aluminum alloy anti-skid plates. In order to reduce the cost and cut corners and shoddy materials, the product has a greater hidden danger and is generally not suitable for use. Products from regular manufacturers can be used.
Usually, when choosing a color-coated aluminum sheet, you must first look at its materials. Some manufacturers cut corners, and the materials are not good. Therefore, you must know the choice of materials to ensure the quality, and then the production process. Up.
