Is galvanized steel heat resistant?
Galvanized coatings perform well under extreme cold and hot temperatures. … At temperatures ranging from 390 F (200 C) to 480 F (250 C), the zinc-iron alloy layers will continue to protect the steel from corrosion.
Is galvanized steel rust proof?
In general, galvanised steel is less expensive than stainless steel. … While the galvanisation process helps protect against rust and provides corrosion resistance, it’s important to note that it eventually wears away, particularly when exposed to high levels of acidity or to salt water.
