Galvanized sheets are iron sheets coated with a layer of zinc for corrosion protection, available in both cold and hot dip methods. In any case, the zinc on the surface will eventually wear off over time, leading to corrosion of the iron. Stainless steel does not require corrosion protection, of course, at a higher cost. Stainless steel remains stable at temperatures between 200-300°C, with only certain special materials experiencing low-temperature tempering at this range; however, at such low temperatures, there are usually no significant changes. Galvanized sheets, on the other hand, will slowly lose their zinc coating when exposed to high temperatures (200°C, 300°C).

There are many types of stainless steel, and galvanized steel perforated mesh is simply a layer of metallic zinc applied to the surface of steel or iron plates. The galvanized steel itself is a plain sheet, just with surface processing. Stainless steel sheets are alloy plates that are corrosion and acid-resistant. Depending on the application, temperatures of 200-300℃ are not considered high; the price of the relatively inexpensive stainless steel 430 sheet should be twice as much as that of the same specification of galvanized coil.

Stainless steel achieves its corrosion-resistant properties by altering the steel composition through the addition of trace elements. Galvanized coil is produced by coating ordinary steel plates with zinc, which serves as a sacrificial layer for corrosion prevention. At 200℃ and 300℃, metals face no issues; however, minor effects can be observed depending on the environmental atmosphere, but these changes would only occur over a long period.

Through the comparison of these aspects, it's clear that stainless steel perforated mesh offers better quality, while galvanized steel perforated mesh has a more competitive price.
