• enhanced corrosion protection, it also provides an
excellent bond for the paint of your choice.
• No more white rust
With pre-galvanized strut, a common quality
concern is the formation of white rust on the zinc
finish. With Galv-Krom® finish, the trivalent
chromium finish is applied over the zinc, to seal
in the zinc beneath and stop the formation of
white rust.
• Great electrical conductivity
Unlike paint or enamel, the Galv-Krom
®
surface
offers a minimum of electrical resistance so
that electrical applications are easily grounded
when grounding is needed.

Finishes
1. Galv-Krom
®
Commonly referred to as “gold,” the Galv-Krom
®
finish is a combination of .5 mils electro-plated
zinc and a gold trivalent chromium finish,
offering superior rust protection and excellent
electrical conductivity.
2. SilverGalv
®
(Suffix EG)
Often referred to as “zinc plated” or “electroplated
zinc,” the SilverGalv® finish applies .5 mils of
zinc and a clear conversion coat. Electro-
galvanizing is available for channel as well as
small fittings, hardware and threaded products.
3. Pre-galvanized steel (Suffix PG)
all Kindorf® channels are available in pre-galvanized
steel. This material is identical to the standard
steel except for its ASTM G-90 zinc coating.
This coating is applied at the steel mill prior to the
channel fabrication.
4. Green coated (Suffix GR)
Green urethane powder resins are applied
electrostatically to the steel after fabrication. Once
the material is completely covered with the
powderedform urethane, it proceeds through a
400° baking process for ten minutes, creating
a chemical bond. This results in a minimum of 1.5
mil thickness of urethane coating providing
excellent resistance to chipping or peeling.
5. Hot-dipped galvanized (Suffix HD)
The material is zinc coated after fabrication
providing total product protection on all
surfaces. The fabricated channel or fitting is
suspended and then dipped into tanks of
hot zinc for a prolonged period, creating a
coherent bond. The result is superior corrosion
resistance as compared to pre-galvanized
material. Hot-dipped galvanizing is not
recommended for threaded products, considering
the zinc coating thickness will often disrupt
the threads.
5. Kindorf® hot-dipped galvanized channel is in
conformance with ASTM Specifications A-123
(formerly A-386) and A-153.
Kindorf® channels maintain a minimum 1.5
ounces of zinc per square foot of steel or 2.5 mils
(ASTM A-123, Thickness Grade 65). This finish is
also referred to as “Hot-dipped galvanized
after fabrication.”
6. PVC Coated (Prefix P)
A polyvinyl chloride (PVC) plastic coating is fused
to the channel, fitting or accessory after fabrication
by immersing the part in fluidized PVC tanks.
The fused-melt mixed powder PVC coating thickness
is 15 mils (.015") plus or minus five mils. PVC material
is a thermoplastic and will soften in high
temperatures. An inherent weakness with PVC
coatings occurs when field alterations are applied,
such as cutting or drilling. These acts disrupt
the sealed PVC product and warrant field touch-up.
ABB cannot be held responsible for field-altered
PVC coated products.

Materials
1. Standard steel
The standard Kindorf® Channel is made from
high-quality ASTM A570 Grade 40 carbon steel
sheet. These sections are cold formed into a
unique and modular profile by an efficient
roll forming process. Additionally, the process
“cold works” the steel is to give it greater
mechanical properties.
2. Extruded aluminum (Suffix AL)
For more corrosive environments, ABB also offers
extruded aluminum channel sections. These section
are nearly identical to their steel counterparts.
Aluminum channel is made from 6063 Aluminum
and heat treated to a T-6 specification.
3. Non-metallic (Suffix N)
Kindorf® channels are also available in fiberglass-
reinforced polyester and vinylester. These
products are pultruded into shapes similar to
steel channels. They offer a high degree of
corrosion protection and are very lightweight.
4. Stainless steel (Suffix SS)
For the most corrosive environments, ABB offers
Type 304 Stainless Steel channel sections and
accessories. Type 316 stainless available
upon request. Contact your local sales rep.
These products are identical to their carbon steel
counterparts except for a much greater
corrosion resistance.
