Galvanized wire

Galvanized wire is mainly divided into three types:
Electro galvanized wire, also known as cold galvanized wire,
Hot-dipped galvanized wire,
Zinc aluminum wire, also known as Galfan.


The production process of galvanized plating:

Black annealed wire → High temperature degreasing→ Acid pickling → Drying → Cold plating → Spooling
Electroplated zinc, also known as cold-plated zinc, is a process that uses electrolysis equipment to place galvanized wire that has been degreased and acid-pickled into a solution containing zinc salt, and connects the negative electrode of the electrolysis equipment. A zinc plate is placed opposite the galvanized wire, and a power source is connected to the positive electrode of the electrolysis equipment, allowing the current to move in a directional manner from the positive electrode to the negative electrode to deposit a layer of zinc on the galvanized wire. The production speed of electroplated zinc is slow, the coating is uniform, and the thickness is relatively thin, usually only 3-15 microns. The appearance is bright, but the corrosion resistance is poor. The amount of zinc on ordinary electroplated zinc wire is generally 8-13 grams/square meter.


Hot-dip galvanizing wire is a method of galvanizing in which zinc ingots are melted at high temperatures and then slowly passed through iron wire to attach zinc to the surface of the wire. The amount of zinc on hot-dip galvanized wire is 30-60 grams/square meter. The production speed is fast, and the thickness of the coating is uneven but acceptable in the market with a minimum thickness of 45 microns and a maximum of over 300 microns. The color is darker, and it consumes more zinc metal, forming an infiltrated layer with the base metal, providing good corrosion resistance. Zinc coating above 100 grams/square meter is typically called "high zinc," and the highest zinc coating can reach 300 grams/square meter.

Black annealed wire → High temperature oil removal → Acid pickling and drying → High temperature galvanizing bath → Spooling.


Galvanized wires made of zinc and aluminum are known as c, with a coating containing high levels of both metals. The aluminum content in Galfan ranges from 5-10%, while zinc makes up 90-95%. The name Galfan comes from the phrase "galvanization fantastique," which denotes an exceptional kind of galvanization. Galfan wires are known for their remarkable corrosion resistance, which is two to three times better than ordinary galvanized wires. Currently, Galfan wires are mainly used in the production of gabion mesh products.
