Does your cold room panel aluminum rust, or does the white painted coat peel off if there’s condensation?

Select domestic high-quality color-coated steel sheet and adopt cold-rolled steel sheet (electro-galvanized steel, hot-dip galvanized steel, or galvanized steel sheet) as the substrate, 
which, after degreasing, phosphating, and chromate treatment, is continuously roll-coated with organic paint before baking. The process goes through a series of production management and quality control steps. 
The commonly used coatings for color-coated steel sheets include PVDF, HDP, PE, and more.
We select color-coated steel sheets that meet the performance standards, which must pass stringent screening: 
coating thickness, corrosion resistance (salt spray), resistance to fading & chalking, resistance to dust adhesion, pencil hardness & gloss, T-bend test & reverse testing related to impact performance, 
and mechanical properties (yield strength, tensile strength, elongation), etc.
