Galvanising a trailer provides added protection against corrosion. Galvanising is appropriate where the trailer is frequently subject to wet conditions or close to the sea.
Hot-dip galvanizing is the process of immersing steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.
According to galvanizeit.org “Hot-dip galvanized steel resists corrosion in numerous environments extremely well. It is not uncommon for galvanized steel to last more than 70 years under certain conditions”.
