Zinc Rack & Barrel Plating Services
Commercial Electro Plating provides zinc rack and barrel plating services which apply the highest quality durable finishes to your steel, brass, and copper parts. Zinc plating is a proven process used to combat corrosion and rust while also providing an attractive finish. Our processing lines are designed to deliver consistent results in both low and high volume production runs. Commercial Electro Plating is also capable of masking critical areas - no plating will be deposited in areas of high tolerance. We have paint, tape, plugs, or caps to cover holes, threads, or critical surfaces.
Our zinc rack lines offer capacities to 13' x 2' x 4' while our zinc barrels measure 18" in diameter and 36" long, giving us the ability to handle both large and small parts with ease. Post-plate operations include application of a variety of finishes, such as clear passivate/blue, and RoHS-compliant yellow trivalent chromium, as well as traditional black and gold hexavalent chromates. We also have a post chromate operation, Ultraseal, which is a topcoat sealant that adds to corrosion protection to the part.
At Commercial Electro Plating we take quality seriously, we deliver plated products that adhere to standards such as, ASTM 633-B-Zinc Electroplating, ASTM B 850-98 Hydrogen Embrittlement, as well as Mil-spec QQ-Z-325B.
