Tri-Yellow gives an iridescent yellow trivalent coating over zinc. Provides excellent corrosion protection.
Tri-Blue is a unique high performance coating over zinc. Tri-Blue is a clear coating with a bluish tint that provides excellent corrosion resistance.
Hex-Chrome Free Zinc  We now offer the following nonhex chromates over zinc to meet RoHS and other directives.
Zinc ¤ Bright Nickel Plating ¤ Other Processes
Zinc Plating is widely used to provide protection for steel and other metals. It is deposited in thicknesses ranging from 0.1 mils (.0001") to over 1.0 mils (.001") thick. The low cost, protective quality and attractive look of zinc makes it a very popular finish for fasteners, metal stampings, computer enclosures, automotive parts and many other items.
Rack and Barrel Plating - IEP does both rack and barrel processing.

Rack Plating is ideal for larger and/or delicate parts which could be damaged in the barrel process. IEP can rack plate parts up to 11 feet long.
Barrel Plating is more applicable for smaller parts which will not be damaged as the plating barrel slowly rotates in the various process solutions.

Both barrel and rack processed parts will produce a very attractive and durable zinc plated finish.
Chromate Coating To increase the corrosion protection of zinc, chromate coatings are normally applied over the zinc. The chromate coatings come in various colors and offer various amounts of protection.
Industrial Electroplating offers the following chromates:
CLEAR - (sometimes called ‘blue bright”)
A shiny silver color with a bluish tint, similar to decorative chrome in appearance.
YELLOW - (sometimes called iridescent or gold)
A yellow to gold color with iridescence.
Offers more corrosion protection than
the clear chromate.
BLACK - A very attractive shiny black.
BLUE - A darker blue to purple which is
used by many for part identification.
OLIVE DRAB - An olive green color with
a higher amount of chrome
for increased corrosion protection.
Other Processes

Powder Coating - Finely ground particles of pigment and resin are electro statically charged and sprayed on a grounded part. The curing cycle melts the powder fusing the coating for a durable high quality finish.

Bright Dip on Brass - We can clean and brighten up brass and then apply a protective film to prevent tarnish.

Stripping and Cleaning - IEP can strip old plating in order to replate or we can strip plating and apply oil to prevent rust. We also clean rust and scale from parts.

Bake to Relieve Hydrogen Embrittlement - As a result of trapped hydrogen, hardened material and certain alloys can become brittle after zinc plating. When required IEP can bake the plated material to remove the trapped hydrogen from under the surface of the material.

Note: If IEP does not have the process you are looking for then we can still help. We work closely with other plating shops to direct clients to the supplier that can best meet their needs.

Bright Nickel Plating is used extensively for decorative purposes. It is also a very durable finish. The combination of brightness and durability accounts for bright nickel being in high demand on consumer goods and other manufactured products.
