Hot Dip Galvanized Guardrail Mesh

Service life：

Generally speaking, the service life of hot-dip galvanized guardrails is relatively long, reaching about 10-20 years in normal outdoor environments. If it is a cold galvanized guardrail mesh, its service life is relatively short, about 5-10 years.    

Reason:

Hot dip galvanizing is the process of immersing the guardrail mesh in molten zinc solution to firmly attach the zinc layer to the surface of the steel wire, forming a thick and dense zinc layer with good anti-corrosion properties. Cold galvanizing is the process of electroplating a layer of zinc on the surface of steel wire, which is relatively thin and has slightly weaker anti-corrosion ability
