Product Description

 

Product Description

Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

We only make high quality products and never cut corners on customers. The error of zinc layer is about plus or minus 10g.The zinc layer has uniform thickness and strong adhesion. No peeling and good corrosion resistance.The zinc layer has uniform thickness and strong adhesion. Processing and forming without peeling, corrosion resistance is very good, after 20 years without corrosion, the surface is very smooth and clean, zinc flower is symmetrical, beautiful.
