How to visually distinguish the quality of Galvanized Wire products
I believe that everyone knows about galvanized wire. Can you distinguish the quality of galvanized wire when you use it? How to choose the quality of galvanized wire.

Galvanized Wire

Firstly, the surface of the galvanized wire with good quality is continuous and smooth. When the plated parts are assembled and combined, there should be no sag, slag or dripping, and there are no defects such as iron on the surface. Good quality galvanized wire, the coating must be uniform, about five times in the copper sulfate solution evenly without iron.

Galvanized Wire

The hammer test was not raised and did not fall off. This is the characteristic that a good galvanized wire should have. How to visually distinguish the quality of Galvanized Wire products
Galvanized wire is divided into hot-dip galvanized wire and cold-galvanized wire (electro-galvanized wire)

Galvanized Wire

Hot-dip galvanizing is immersion plating in hot melted zinc bath. The production speed is fast, the coating is thick but uneven, and the market allows a minimum thickness of 45 microns and a maximum of 300 microns or more. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. The hot-dip galvanizing can be maintained for several decades in an outdoor environment.

Galvanized Wire

Cold galvanizing (electro-galvanizing) is the gradual plating of zinc on the metal surface in the plating tank by the unidirectional current. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. It will rust in a few months. Relative to hot-dip galvanizing, electro-galvanized production costs are lower.
