• Strong Abrasion Resistance
SilverGalv
®
provides strong abrasion resistance, even under extreme
conditions, thanks to its unique zinc finish and chromate barrier. The
green paint finishes typically used for strut cannot compare to this
level of protection
• Clean Finish
SilverGalv
®
ensures a finished product that leaves no residue on
your hands. In the SilverGalv
®
process, a zinc finish is applied after
fabrication. As a result, all the oil and grime that accumulates during
manufacturing gets thoroughly cleaned off during the plating process
• Paintable Surface
Applying SilverGalv
®
after fabrication provides the end user
with a clean, smooth surface to paint
• Interchangeable Silver Color
SilverGalv’s silver hue means it can be used interchangeably with
either standard pre-galvanized channel systems or silver colored
fittings commonly used with green painted strut systems
• No More White Rust
With pre-galvanized strut, white rust frequently taints the zinc finish.
With SilverGalv
®
, this problem is eliminated thanks to a clear
chromate applied over the zinc that stops white rust from forming
• Punched Holes and Cut Ends are Protected
Unlike a pre-galvanized finish where steel holes and cuts have no
corrosion protection, Silver-Galv
®
protects every portion of the strut.
Because SilverGalv’s finish is applied after fabrication, all punched
holes and cut ends share a consistent quality with the rest of the
material

GoldGalv
®
hardware finish is standard for all Superstrut
products. This is a multi-process finish of electro-plated
zinc, followed by gold colored zinc dichromate to give
excellent corrosion resistance and superior paint base.
See page D-4 for a complete description of the GoldGalv
®
hardware finish. GoldGalv
®
hardware will be furnished
