For desert areas, the perennial wind and sand are challenges for color-coated sheets, especially for the surface of color-coated steel buildings. The paint film of the color-coated sheets is easy to peel off, thereby making the primer and the substrate exposed to the air which accelerates the corrosion of the sheets.

For areas where there is a lot of wind and sand, when choosing color-coated steel sheets, the sheets with thicker paint films can be the first choice. Thick paint films can be better protectors for the primer and substrate, and can also extend the life of the color panel.
SMP( silicon modified polyester ) color-coated sheets from Shinmade are more suitable for areas with severe wind and sand due to their coating hardness, abrasion resistance, chalking resistance, durability and other characteristics.
