The galvanized sheet is coated with a layer of metal zinc anticorrosion on the iron sheet. There are cold plating and hot plating. In short, the zinc on the surface will fall off, the iron will be corroded, and the stainless steel will not need to be anticorrosive. Of course, the price is expensive. 200-300 stainless steel, special materials have only a low-temperature tempering at 200-300 °, but generally the temperature is too low no significant change in the surface layer of zinc galvanized sheet is slowly at high temperatures (200 degrees, 300 degrees) Bake it off.
There are many types of stainless steel, and the galvanized sheet is just electroplated once on the surface of the steel sheet or iron sheet. Galvanized sheet itself is general board, surface processing done only. The stainless steel plate is an alloy plate that resists acid. Do you see what purpose, not a high temperature 200-300 degrees, relatively inexpensive 430 stainless steel plate prices should be 2 times more expensive than the same specifications of galvanized sheet.Stainless steel achieves the purpose of anti-corrosion by adding trace elements to change the composition of steel. Galvanized sheet steel is galvanized in ordinary surface, achieved at the expense of zinc manner of a preservative. 200 degrees and 300 degrees are not a problem for metals. Looking at the environmental atmosphere, there will be some very small effects, but it will take a long time to change.
