Solar Industry

Color coated aluminum is used for solar panel frames and components due to its lightweight and corrosion-resistant properties.

After surface contamination is washed off in Acid Cleaner tanks, the coil then passes through a series of freshwater tanks for Rinsing off the acid cleaner from its surface, which is again, done by soaking & spraying.

Passivation or Conversion Coatings are chemical treatments applied to the Aluminum coils after cleaning and prior to painting. They are designed for following :-
