Galvanized wire is created by coating carbon steel wire with zinc. This can be done through electro-plating or hot-dip galvanizing. Galvanized steel wire is a kind of versatile material which is coated with zinc to make it corrosion resistant. Galvanized steel wire is a durable and high-strength material. Its lightweight property also makes it easy to cut and use. Galvanized wire is used in the automotive, construction, bedding, and poultry industries. It can be used directly or further processed for different applications, such as handicrafts, fencing, packaging, nails, etc.

The GI wire manufacturing process is very simple. Here is it.
Wire Rods - Pickling (annealing - rust removing - acid washing) - Wire Drawing Process - Galvanizing Process - Stranding
The first step is the pickling process, including annealing, rust removing and acid washing, which aims to remove the impurities on the surface of wire rods. Then it will go through the drawing machine, steel wires will be formed into the desired size. Then the wire will be galvanized by dipping into zinc solution or electroplating. This is the main difference between hot-dipped galvanized and electro galvanized wires. After galvanizing, the GI wires will be rolled into coils for sale.
Galvanized wire provides excellent corrosion resistance, great durability and high tensile strength. Besides, its surface is smooth and shiny. That's why it is widely used in many applications.
1. Binding Materials
Because galvanized steel wire is strong and durable. It is often used as binding or baling or earthing materials on construction sites. Due to its weather resistance, it is very popular among builders. You can also find GI wires used to make gabions.
2. Protective Fencing
Since galvanized steel wire is strong, it is widely used to make fencing or enclosure around your home or property from thieves or animals. Besides that, galvanized steel wire is corrosion resistant which makes it suitable for outdoor uses. You can also find GI wire fencing around schools, sports fields, etc. A GI wire fence will be an easy and useful way to keep your home safe and secure.
3. Making Handicrafts
The galvanizing process gives steel wire a bright and glossy surface. It can be made into household handicrafts such as bookshelves, vase holders, storage baskets, etc.
4. Agricultural Uses
GI wire is also widely used in orchards for supporting the growth of grapes or tomatoes and other vegetable farming. Due to the zinc coating, it can withstand the corrosion of pesticides and other chemicals.
5. Other Daily Uses
Galvanized wiring is also often used in packaging, animal cages, hanging pictures or painting, etc.
