High Temperature Galvanized Coating Options

[schulkfl]

I currently have a unit that is made of zinc-coated mill galvanized steel. It is my understanding that reaching temperatures above 230°C will cause the metal to flake and compromise the mechanical properties.
Are there cost effective alternatives that will allow us to reach ~300°C without having these issues (for example, other coatings)? The material or coating must be corrosion resistant as the unit is outdoor.


Thanks in advance for any help-

Aluminized steel works to higher temps than 300 [°]C.
