NOTES:
- At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
- For 304 SS metal, bluing may occur at temperatures of 800° F and above.
- Rock River Silicone Sealant and Red Devil HVAC/R High Temperature Silicone Sealant are not able to be painted.
