In recent years, hot dip galvanized fence has been applied to many areas, the advantage lies in galvanizing anti-corrosion life long fence, and adapt to the environment has been a widely popular anti-corrosion treatment. Is widely used and the power tower, communication tower, railway, highway fence, lampposts, marine components, building steel components, substation ancillary facilities and light industry.

Principle highway fence for hot-dip galvanizing process: welded wire mesh will be cleaned, and solvent-treated, dried and dipped in molten zinc, welded wire mesh molten zinc reacts with an alloyed zinc layer, the process is: degreasing - washing - pickling - fluxing - drying - hot-dip galvanized - separation - cooling passivation. For the thickness of the alloy layer of hot galvanized rail fence it depends mainly on the silicon content of the steel and other chemical ingredients, with cross-sections of steel, the surface roughness of steel, zinc pot temperature, zincation time, cooling speed, cold deformation.
