The company chooses high-quality chemical raw materials and advanced technology to transform the surface of aluminium coil. The forming line can clean all kinds of dirt adhering to the surface of aluminium coil and remove the precipitation of impurities such as silicon, magnesium and copper on the surface of aluminium material. Aluminum rolls are coated with various paints according to customers'needs.

The coating line adopts advanced precision three-roll reverse rolling machine to finish the coating precisely in the closed dustless state, which controls the thickness of the coating film and the appearance quality of the coating precisely. The baking oven is divided into four zones to control the temperature, so that the solvent resistance, hardness and flexibility of the coating can reach a good state, and the product has good gloss, adhesion and corrosion resistance.

The main indexes of coatings are strictly tested in accordance with national standards: film thickness, aluminum foil thickness, flexibility, impact resistance, solvent resistance, pencil hardness, adhesion, boiling resistance, acid and alkali resistance to ensure the durability of beautiful appearance and color.
