GoldGalv
®
hardware finish is standard for all Superstrut
®
products.
This is a multi-process finish of electro-plated zinc, followed by gold-
colored trivalent chromium to give excellent corrosion resistance and a
superior paint base. See pages B-106–B-107 for a complete description
of the GoldGalv
®
hardware finish.
Note: Standard Spring and Springless Nuts are supplied with a silver electro-galvanized (EG)
finish. These items are not visible in a gold system and are universal with other systems’
finishes and colorations.
Superstrut
®
channel nuts are manufactured from mild steel
and are case hardened.
Design Data
Superstrut
®
self-aligning channel nuts are designed to provide resistance
to pull out and resistance to side slip in excess of the full strength of the
channels with which they are used. The extreme resistance to side slip
results from the unique design of the alternate teeth, spaced and designed
to develop a wedging action that increases with pressure or load.
