Finishing
A key element in the quest for perfection, Capitol’s finishing processes are of the highest quality.
Zinc alloys do not require a surface coating in many engineering applications but if a finished product is what is specified we have the in-house capability to provide many of the standard industry finishes.
Capitol Industries inc. produces many millions of chrome, brass. nickel, copper, zinc chromate, antiques, olive drab, yellow chromates and powder coating parts per year.
