ASTM B117 salt spray test, the new Galv-Krom
®
finish provided improved protection to the
previous Hexavalent formulation, and
substantially more protection than painted
finishes or G-90 Pre-Galvanized (see figure 01).
This outstanding corrosion protection means
more versatile installations and more service life
for Galv-Krom

• Clean finish
For pre-galvanized finishes, the zinc finish is
applied before the strut is manufactured.
That means all the oil and grime collected while
the steel is formed into strut remains on the strut
for the customer. Because Galv-Krom
®
finish
is applied after fabrication, the oils and grime
collected during the manufacturing process
arethoroughly cleaned off during plating.
This creates a finished product that leaves no
residue on your hands when handling.
• Paintable surface
The new Galv-Krom® finish uses nano technology
to provide a nonporous and non-crystalline
surface. Not only does this feature provide
