What is the difference between galvanized sheet and stainless steel?

Galvanized sheets are copper sheets coated with a layer of metallic zinc to prevent corrosion. There are cold plating and hot dip galvanizing. In short, the zinc on the surface will fall off over time and the iron will be corroded. Stainless steel plates do not need to be anti-corrosion. , naturally the price is expensive. Stainless steel plates cost 200-300, and some materials are quenched at ultra-low temperatures of 200-300 degrees, but the temperature is too low and generally there is no big change. The zinc on the lower surface of the galvanized plate is at high temperatures (200 degrees, 300 degrees). It will be gradually baked away. There are many types of stainless steel. Galvanized sheets only use zinc metal electroplating on the surface of thick steel sheets or stainless steel sheets. The galvanized sheet itself is a common sheet, and the surface layer is just processed. The stainless steel plate is an acid-resistant alloy aluminum plate. Depending on what purpose you are using, 200-300 degrees is not considered a high temperature. The price of the relatively cheaper stainless steel 430 plate should be twice as expensive as the galvanized plate of the same specification. Stainless steel plates are designed to change the composition of stainless steel plates by adding nutrients to achieve anti-corrosion effects. Galvanized sheets are hot-dip galvanized on the surface of ordinary thick steel sheets to achieve anti-corrosion purposes by removing zinc. 200 degrees and 300 degrees are not a problem for metal materials. Depending on the environmental atmosphere, there will be some minimal harm, but it will take a long time to change.
