Why Gold Coat is the Best Option

Based upon our testing conducted at Michigan State University, Gold Coat provides superior corrosion resistance as compared to G90 and G185 galvanized products that are currently on the market.

Visual inspection of the three products shows dramatic deterioration in the G90 and G185 connectors, as compared to the Gold Coat connector.

Cross sectional micro analysis tell a better story. Tested samples in each category were sliced into thin cross-sections and mounted for analysis.









In each of the photo micrographs, you will see varying degrees to which the corrosion has been able to attack and eat away the protective layers of each product.

G90 with treated wood – after 120 days in test chamber Note the severe corrosion: The zinc layer is completely gone and iron oxide is eating down into the steel substrate. [view]
G185 with treated wood – after 120 days in test chamber Note the severe corrosion: The zinc layer is completely gone and iron oxide is eating down into the steel substrate. [view]
with treated wood – after 120 days in test chamber Note that the Gold Coat and zinc layers remain with uniform thickness. The Gold Coat barrier has not been breached and corrosion has been resisted! [view]

Additionally, Energy Dispersive X-Ray Analysis (EDXA) further indicates the superior protection provided by the Gold Coat barrier system. This analysis identifies what chemicals are on the surface of the material being analyzes.
