Galvanized is making the metal surface zinc coated, this process is including electro galvanized and hot dip galvanized. Let us talk the how to distinguish the difference between hot dipped galvanized wire and electro galvanized wire.

First, electro galvanized is one-way zinc the metal wire surface gradually trough electric current in galvanizing pot. Production rate of the method is slow and evenly zinc coated uniform. But because the zinc is thin and surface is bright, the corrosion resistance is poor.

Hot dipped galvanized is zinc coated in heated and melt zinc liquid. Production rate of the method is fast ,zinc coated is thick and corrosion resistance is great.

So we want to distinguish between hot dipped galvanized wire and electro galvanized wire, we just to see the appearance.: The wire is bright and zinc coated is thin ,which is electro galvanized wire. And the wire zinc coated is thick and looks white ,which is hot dipped galvanized wire.Just put them together to compare, it is easily to distinguish.
