The colors are diverse and stable, and basically all the colors in the Raul color card can be realized. The paint used can be polyester paint or fluorocarbon paint. Basically, polyester paint will not change greatly in 15 years, and fluorocarbon paint can reach an astonishing 30-50 years.

It Has A Series Of Advantages To Replace Color Steel Products, Mainly In:

1. The colors are diverse and stable, and basically all the colors in the Raul color card can be realized. The paint used can be polyester paint or fluorocarbon paint. Basically, polyester paint will not change greatly in 15 years, and fluorocarbon paint can reach an astonishing 30-50 years.
2. The surface will not rust. First of all, the paint surface will form a better protection for the aluminum plate. In addition, a stable oxide layer will be formed on the surface of the aluminum plate to prevent further erosion of the environment. Solve your headaches once and for all.
3. The residual value of recycling is high, and the recycling value of aluminum is high, which can basically reach about 70-80% of the original value (there will be differences depending on the region), so when you use it for 20 or 30 years, if you want to dismantle it, you still need to pay for it. Can sell for a good price. If the price of aluminum rises, even the selling price will be higher than the money spent in the past. So many years are equivalent to useless, and even make money. Would you still choose color steel for such a value-preserving product?
4. Aluminum is relatively soft and can be easily bent and various shapes can be realized. Welding and bending are even easier.
PE or PVDF Coated Al alloy 3003 and 3004 silver grey metal roof panels is a product we often use on roofs. If you like light-colored roofs and want to use them for more than 30 years, you can choose this product with confidence.
