What is the difference between galvanized wire and hot-dip galvanized wire?
Electro-galvanized wire: also known as cold galvanized wire; it uses electrolytic equipment to deoil, pickle, and then put the pipe fittings into a solution of zinc salt, connect the negative electrode of the electrolytic equipment, place a zinc plate on the opposite side, and connect it to The positive electrode of the electrolysis equipment is connected to the power supply, and the directional movement of the current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings. Slow, the coating is uniform, the amount of zinc on the galvanized wire is relatively thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor.
Galvanized Wire: also known as cold galvanized wire, the tube will be de-oiled with electrolytic equipment, pickling, and then the tube into a zinc salt solution, connected to the negative electrode of the electrolytic equipment, placed opposite the zinc plate, connected to the tube. The positive electrode of an electrolytic device is connected to a power supply, and the directional movement of the current from the positive to the negative will deposit a layer of zinc on the tube. Slow speed, uniform coating, zinc content on galvanized wire is thin, generally only 3-15 microns, appearance bright, poor corrosion resistance.
The electro-galvanized wire is mainly used in communication equipment, medical equipment, woven mesh, brush, wire rope, filter mesh, high-pressure pipe, construction, handicraft, and other industries.

Hot-dip galvanized wire is pickling, phosphating, wire-drawing, and galvanizing of various high-quality medium carbon steel or high-quality high-carbon steel; But it is not uniform, the minimum thickness allowed by the market is 45 microns, and the maximum thickness is more than 300 microns. The color is darker, consumes a lot of zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance, and hot-dip galvanizing can be maintained for decades in an outdoor environment.
Hot-dip galvanized steel wire is all kinds of high quality medium carbon steel or high carbon steel pickling, phosphating, wire drawing, galvanizing, but its thickness is not uniform, the minimum thickness allowed in the market is 45 microns, the maximum thickness is more than 300 microns. Deep color, consume a lot of zinc metal, with the base metal forming a permeable layer, and has good corrosion resistance, and hot-dip galvanizing can be kept in outdoor environment for decades.
Due to the thicker amount of zinc on the hot-dip galvanized wire, hot-dip galvanizing has better protective performance than electro-galvanizing, so it is an important protective coating for steel parts used in harsh working environments. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, marine exploration, metal structure, power transmission, shipbuilding, and other industries. , highway guardrails, etc., have been widely used in recent years.
