Rolling Counter Doors

Material and Finish

Cornell’s metal closure products are offered in steel, stainless steel or aluminum. Finish options allow Cornell products to fit—and often contribute to—the visual aesthetics of a building project. When enhanced resistance to chemicals, corrosion, moisture, rust, or abrasion is needed, Cornell has materials and finishes that will meet or exceed the requirement.

Available Material Finishes for Steel:

Exclusive GalvaNex™ Finish for Sheet Metal Curtains & Hoods - Coating System includes an ASTM A 653 galvanized base coating treated with dual process rinsing agents in preparation of a chemical bonding, light gray baked-on polyester base coat and a light gray baked-on polyester finish coat. The scientific organic material composition and chemical bonding process of GalvaNex produces a superior finish against corrosion and abrasion.

Hot Dipped Galvanized - Hot liquid process applies protective zinc coating in metallic silver finish.

ZRG - Zinc Rich Gray powder coating is smoother, more uniform and more durable than solvent based ZRC Zinc Rich Coating.

Available Material Finishes for Aluminum:
