RAL1002 sand yellow Anti Corrision powder coating for metal surface with Excellent UV properties.
Anti-corrosion refers to the protection of metal surfaces from corroding in high-risk (corrosive) environments.
When metallic materials are put into corrosive environments, they tend to have chemical reactions with the air and/or water. The effects of corrosion become evident on the surfaces of these materials. For example, after putting a piece of iron into a corrosive atmosphere for an extended period, it starts rusting due to oxygen interaction with water on the surface of the piece of iron.
