A galvanized pallet truck is a standard steel pallet truck that has a protective coating designed to be corrosive resistant. The galvanized pallet trucks will not rust for a long period of time. One thing to be aware of, if galvanized pallet trucks are used in salt water environments such as near the shores of lakes or seas then the salt will eventually eat away at the protective coating and the galvanized pallet truck will rust. A stainless steel pallet truck is composed mainly of stainless steel which because of its chemical composition is completely rust-proof. Because stainless steel does not rust no protective coating is necessary from corrosion. If you need a pallet truck to function in a humid, salt water, or sanitary work environment then a stainless steel pallet truck is the right pallet truck for the job.
