Galvanized sieves include cold galvanized sieves and hot-dip galvanized sieves. The cold galvanized wire mesh will not rust in a short time. Hot-dip galvanized wire mesh will not rust, mainly zinc wire. Zinc-containing cold galvanized wire is not easy to rust. Zinc-containing hot-dip galvanizing will not produce a lot of rust.
Nickel and zinc are two metal elements that are not oxidized by water. The cost of nickel is high, it is non-magnetic, and the cost of zinc is low.
