Advantages of Our Prepainted Galvalume Steel Coil

1.Resistance to acid rain

Coating protection mechanism : It is very easy to form acid rain in the high level of industrial emissions or pollutants enviroment. Acidic penetration is formed in the surface of pre-painted steel, and accelerates the corrosion, forming blistering, peeling and so on.

2. Resistance to ultraviolet rays

Coating protecting mechanism: Pre-painted steel in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and loss of gloss, lose paint quickly.

3. Resistance to humid heat

Coating protecting mechanism : In it and humid environments, high osmotic pressure ot water vapor accelerates penetration, forming the degeneration of painting film, then the corrosion of the substrate, with the phenomenon of bubbles and peeling.

4.Resistance to low temperature

Coating protecting mechanisms: Most of the paint can keep stable processing performance above -10 degree, but at alpine region, the temperature will be below 20-40 defree, normal paint will become brittle, bend cracking, or even lose paint, thus protection function is lost totally.

5.Dual strong

Intense hear reflectance: RHT pre-paint steel uses aluminum zinc substrate, the reflectivity is two times stronger than galvanized sheet, therefore they are the ideal energy saving materials.

Intense skin-pass surface: After skin-pass process, RHT galvanized steel substrate overcomes the common tension leveling lines and the surface is flat and smooth.
