Galvanized sheet is a layer of metal zinc on the iron sheet for anti-corrosion. There are cold galvanizing and hot galvanizing. In short, the zinc on the surface will fall off for a long time, and the iron will be corroded. Stainless steel does not need anti-corrosion. Of course, the price is expensive. Stainless steel is 200-300 degrees, only some special materials are tempered at 200-300 degrees low temperature, but the temperature is too low, there is generally not much change, and the zinc on the lower layer of the galvanized sheet will be slowly removed at high temperatures (200 degrees, 300 degrees). Bake off.

There are many types of stainless steel, and the galvanized sheet is only plated with metallic zinc on the surface of the steel sheet or iron sheet. The galvanized sheet itself is a common sheet, and it is only surface processed. The stainless steel plate is an acid-resistant alloy plate of Fangfu. Depending on what you do, 200-300 degrees is not considered a high temperature, and the price of relatively cheap stainless steel 430 plate should be twice as expensive as that of galvanized plate of the same specification.

Stainless steel achieves the purpose of changing the composition of the steel by adding trace elements to achieve the anti-corrosion function. Galvanized sheet is galvanized on the surface of ordinary steel plate to achieve anti-corrosion purpose by sacrificing zinc. 200 degrees and 300 degrees are not a problem for metals. Depending on the environment, there will be some extremely small effects, but it will take a long time for changes.
