Finish
Mastercoat Finish (ten-year warranty)
- Near white to white metal blast using synthetic silica grit, as
specified by the Steel Structural Painting Council (SSPC SP-10 to SP-5)
and the National Association of Corrosion Engineers (NACE No. 2 to NACE
No. 1) to remove macro-rust, mill scale and exposed surface metal, and
to etch the material for maximum powder adhesion.
- Alkali chemical wash to remove micro-rust, grease and oils.
- Fresh water rinse.
- Phosphate treatment to inhibit rust prior to coating.
- Fresh water rinse.
- Non-chrome sealer to create a water break free surface.
- Preheat to eliminate moisture, reduce Faraday cages, and prepare the metal for coating.
- Cool material to enable consistent coating thickness throughout.
- Apply 1.5-3 mils of epoxy powder base coat to maximize corrosion protection.
- Oven baked to cure powder 50-60%, enabling maximum adhesion of the base coat to the metal.
- Apply 2-4 mils of TGIC polyester powder top coat to minimize weathering.
- Oven baked to cure double layer of powder to form a 3.5-5 mil uniform
coating throughout that resists rusting, fading, chipping and peeling.
Standard Powdercoat (one-year warranty)
- Alkali chemical wash to remove micro-rust, grease and oils.
- Fresh water rinse.
- Phosphate treatment to inhibit rust prior to coating.
- Fresh water rinse.
- Non-chrome sealer to create a water break free surface.
- Preheat to eliminate moisture, reduce Faraday cages, and prepare the metal for coating.
- Cool material to enable consistent coating thickness throughout.
- Apply 2-4 mils of TGIC polyester powder top coat to minimize weathering.
- Oven baked to cure powder to form a uniform coating that resists rusting, fading, chipping and peeling.
Galvanized Finish (one-year warranty)
- Acidic pickling chemical wash to remove micro-rust, grease and oils.
- Fresh water rinse.
- Flux core treatment.
- Dipped in zinc galvanizing bath.
