ENHANCED CORROSION RESISTANT CHANNELS, FITTINGS AND FASTENERS

摘要

A corrosion resistant support system includes a first channel member having a first corrosion resistant coating. The first corrosion resistant coating is a zinc-aluminum-magnesium coating. A fitting is engageable with said channel member and a first mechanical fastener to couple the fitting to the channel member, the fitting and the first mechanical fastener having a second corrosion resistant coating. The second corrosion resistant coating is a thermal diffusion galvanized coating or a zinc-aluminum-magnesium coating. The first channel member and the first mechanical fastener may also have a third corrosion resistant coating disposed over the first and second corrosion resistant coatings, respectively. The third corrosion resistant coating can be a Perma-Green™ coating, a powder coating, an electrocoating (E-coat or Electrophoretic deposition coating), a paint coating, an epoxy coating, a polyvinyl chloride (PVC) coating, a trivalent chromium coating, a hexavalent chromium coating, a zinc coating, and/or a copper coating.
