Application industry: iron ore, coal, other ore mining industries.

Industry characteristics: The mining environment is relatively harsh, the sand dust is more serious, the dust is mixed with metal dust, and the sediment is corroded after being immersed in rainwater on the surface of the color coated board, which is more destructive to the corrosion of the color coated board. After the ore deposited on the surface of the color coated plate is blown by the wind, the damage to the surface of the coating is also severe.

Material selection criteria:In view of the harsh environment at the mining site, it is recommended to use SMP silicon modified polyester color plate which is resistant to corrosion, scratch and abrasion. The substrate is a galvanized sheet having a double-sided zinc layer of not less than 120 g/m 2 and a front coating layer having a thickness of not less than 20 μm.
