Brand: Shandong Hanchen
Many users of color steel products are facing such problems:
1. The color becomes old: If your color steel panel does not use high weather-resistant paint, the color of the paint will gradually fade after a long period of wind and sun exposure, especially for brighter colors.
2. Rust on the surface: the substrate of color steel plate is iron plate. We know that iron plate is extremely easy to rust. After a long time of oxidation, the rust on the surface will give you a very headache. Rust on the surface will cause the paint surface to peel off, further affecting the appearance. In the end, there is no choice but to remove rust and repaint, which will cause secondary consumption and affect production and use.
3. The salvage value of recycling is low. If it is planned to be demolished, the price of the used color steel plate is extremely low. Because of the paint surface, its price is even lower than that of ordinary scrap iron.

It is impossible to realize a variety of shapes. The hardness of color steel is relatively high, and it can go straight. If it is bent or designed in other shapes, it will be difficult to realize, and even if it is barely realized, the aesthetics will not be very good.
Now let us introduce PVDF coated AL alloy coil, a perfect substitute for color steel plate, which has many advantages as follows
1. Light weight: the density of aluminum is 2.73KG/M³, only 1/3 of that of steel;
2. High strength: high strength can be achieved through composition configuration, processing and heat treatment methods;
3. Corrosion resistance: with self-rust prevention ability, the formation of oxide layer, can prevent metal oxidation corrosion, good acid and alkali resistance;
4. Diverse surface treatment, beautiful: anodizing, electrophoresis, chemical treatment, polishing, painting treatment;
5. Good plasticity and easy processing;
6. Good electrical conductivity: non-magnetization and low spark sensitivity, can prevent electromagnetic interference and reduce the flammability in special environment;
7. Easy installation: aluminum metal can be riveted, welded, glued and other ways to connect;
8. Single Color PVDF Coated AL Alloy Coil Environmental protection: 100% recyclable.
PVDF is fluorocarbon paint which is a high-performance two-component coating with excellent physical and chemical properties. Fluorocarbon paint has the advantages of weather resistance, self-cleaning, corrosion resistance, solvent resistance, color retention and gloss retention, etc. The paint film has various colors , including solid paint and metallic flash paint. The fluorocarbon paints we use are all high-quality paints higher than 70% fluorocarbon.
