Lites & Louvers

CANADIAN GEESE - The Canadian goose is the most recognizable goose in North America. Its black and white head and characteristic "honking" call make the Canadian goose an easily identifiable bird. They are known to take up residence in urban environments and to discontinue migrating if conditions are acceptable.

Corrosion Resistant Sealer: A polymeric green seal (non-chrome) corrosion resistance extender is applied under all NGP powder coat finishes. Laboratory salt spray tests prove a dramatic increase in corrosion resistance on steel products with this sealer applied to the metal prior to the powder coat finish.

Salt Spray Test Results: Steel lite kits with NGP's corrosion resistant sealer and powder coat finish withstood 1,248 hours without failing. This is 2-1/2 times longer than the protection provided by powder coating only.

Zinc Electro-Plating

Available on steel lite kits and louvers for extra corrosion resistance; recommended for exterior, wet areas, and coastal salt air locations. Zinc electro-plating will be applied prior to the powder coat finish. Specify on order "Zinc EL-Plate" and powder coat color desired. Not available on insect screen.
