Pre-painted steel coils are used in roof structure, surface sheet of balcony, frame of window, folding screen and electrical equipment. Pre-painted steel can be formed into almost any shape, and it has excellent resistance to weathering, superior longevity and texture options.
Product Core Benefits:
Acid Rain Resistance
Coating Protection:Acid rain is easily formed in highly intensive industrial emissions or heavily polluted environments. Acid penetration on the surface of the color map will accelerate its corrosion, forming blisters or even peeling off the skin, etc.
UV Resistance
Coating protection: Color map in the ultraviolet light or strong sunlight conditions, the coating will appear fading, discoloration and loss of luster, rapid decoloration.
Resistant to heat and humidity
Coating protection:In hot and humid environments, the high pressure of water vapor accelerates penetration, forming the degradation of the paint film, and then corrosion of the substrate, bubbles and peeling phenomenon.
Low Temperature Resistance
Coating Protection:Most paints can keep their performance stable above 0 degrees, but in high mountain areas, the temperature will be lower than 20 - 40 degrees, the normal paint will become fragile, bending and cracking, and even peeling off the paint, thus losing the protective function completely.
