Louvers are available in Cold Rolled Steel, Galvanneal Steel, and Aluminum Alloy 6063-T5
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.
