No Exposed Bolts
Our hardware connections are hidden within the beams to provide aesthetic elegance.
Powder Coating: Setting the Stage
1. Blast to White: Blast all steel to “White” condition to remove all surface rust and oil. This process insures a raw steel finish for proper adhesion for Stage 4 (Zinc TGIC Powder Prime Coat).
2. Air Induction Cleaning: Remove dust from the blast process in stage 1.
3. Preheat Steel: Pre-Heat steel at 1.5 ft per line minute for 13ft in IR oven to a temperature of 250 Degrees to prepare steel for Stage 4 (Epoxy TGIC Powder Coating Zinc Rich Primer Process).
4. Zinc Rich Powder Coating: This stage is the Electrostatic Application of Epoxy TGIC Powder Coating Zinc Rich Primer. Unlike any other shelter manufacturer, we are utilizing an actual TGIC Zinc Powder Coating Rich Primer. This stage 3 application is applied at 3 mils and has been salt spray tested for 4,000 + hours using the ASTM Method B117. (Note: The 4,000 hours of salt spray testing is only with the Zinc Rich TGIC Powder Coat Primer and before the Stage 5 TGIC Top Powder Coat application of an additional 3 mils of TGIC Powder Coat.)
5. Top Powder Coating Color: This stage is the Electrostatic application of TGIC Top Powder Coat at 3 mils. This application, along with the Stage 4 Epoxy TGIC Powder Coating Zinc Rich Primer, produces a total of 6 mils of finished Powder Coating and has tested at 5,000+ hours using the ASTM Method B117. It is important to note that testing was discontinued at 5,000 hours.
6. Curing Process: The final stage is the final cure of coatings at 450 degrees for 30 minutes.
