Aluminum Fence Savannah GA

Pre-treatment

All Colonial Aluminum® fences are given a 9-step pre-treatment process that cleans and prepares the aluminum to assure
complete adhesion of the powder coating.

1. Our raw premium grade aluminum is
   inspected to be free of blemishes and is
   not exposed to outdoor elements.
2. Product enters heated alkaline cleaner
   stage to remove extrusion and
   fabrication oils.
3. City water rinse.
4. Reycling reverse osmosis water rinse.
5. Pure reverse osmosis water rinse.
6. Primer/sealer conversion coating which provides a
   strong adhesion of coating to
   the aluminum.
7. Pure reverse osmosis water rinse. Final rinse is of
   the same quality as bottled drinking water. Clean
   water removes contaminates which will hinder
   coating performance.
8. A 200 MPH air blast removes water drops from
   the pre-treated product.
9. A convection oven completes the dry-off
   process for a clean dry surface to powder coat.
10. Powder application is automated.
    Compressed process air is dried to -35°F
    Dew Point for superior adhesion and
    aesthetics. The powder booth contains
    powder coating overspray with no
    emissions to the surrounding environment.
11. The final step of the powder coating process is
    the cure oven where the powder coating gels
    and bonds to the aluminum.
