Coating Type Color Thickness/um SST/h PCT/h Working Temp/℃ Performance features
Blue Zn Blue/White 5-10 ≥48 <160 Medium corrosion resistance performance
Color Zn Multiple colors 5-10 ≥72 <160 Medium corrosion resistance performance
NICUNI Silver white 10-30 ≥72 ≥96 <200 High corrosion resistance,thermal resistance and moisture resistance
PVD Aluminium Silver white 5-25 ≥96 ≥240 <390 High corrosion resistance and adhesiveness
Phosphate <250 Low cost,low corrosion resistance performance
Epoxy Black/Grey 10-30 ≥480 ≥96 <180 High corrosion resistance and insulation performance
Multi-layer coating ≥1000 ≥480 Excellent corrosion resistance performance


This performance might vary according to different dimension of product.

Multi-layer coating is a combination of different type of coatings, and its color,thickness and working temperature might varies from different combinations.
