PT2000® is used for more corrosive wood treating chemicals and many exterior applications like: decks, fences, boat docks, boardwalks, and playground equipment. It works great in any pressure treated lumber. Salt spray tests show no corrosion in over 1,500 hours.
For more information on corrosion resistance, see PT2000®.
PPG1500™ by PPG allows color matching to products such as composite decking while still providing corrosive protection. Salt spray tests show no corrosion in over 2,000 hours.
Yellow Zinc coating is used for temporary corrosion resistance. It should be used for interior or weatherproof applications. YZ coating is not designed for use with Treated Lumber or exterior applications. It has a beautiful gold color. Class 1 galvanized ASTM A641/A64M-98 is available on request (special order only).
305 is an austenitic chromium-nickel stainless steel that is not magnetic. It cannot be hardened by heat treatment. It is corrosive resistant. ASTM B-117 Salt Spray Tests show no sign of surface red rust at 1,000 hours.
316 is an austenitic chromium-nickel stainless steel containing molybdenum. It provides an increased strength at higher temperatures and provides the highest corrosive resistance. ASTM B-117 Salt Spray Tests show no sign of surface red rust at 1,000 hours.
410 is a martensitic grade of stainless steel that is magnetic. It is corrosive resistant in mild chemical environments. When coated with PPG1500™, ASTM B-117 Salt Spray Tests show no sign of rust at 5,500 hours.
