Galvanized Welded Mesh Types and Comparison

Galvanized welded wire fabric is economic and practical for many applications, just as its name implies, the surface of welded mesh is coated with a thin layer of Zinc in order to prevent rust, it has two different surface treatments, galvanized before weld and galvanized after weld, both of them have their advantages and disadvantages.

Galvanized Welded Wire Mesh Before Welding

Galvanized Welded Mesh After Welding

Welded wire mesh that is galvanized after welding is last longer than that galvanized before welding, because it’s made of the untreated surface welded mesh which is dipped into to the molten zinc, the entire mesh including the welding spots is covered with much more zinc. So generally welded wire mesh which is galvanized before welding is cheaper than that is galvanized after welding.
