Steel is the most important part of almost all other industries nowadays. Steel Wires play a very important role in our day-to-day activities. From a small screw in our chair to large railway tracks, steel is the major component. Every steel wire has its own significance in the projects for which they are used. Some steel wires are known for their durability, some are for their anti-corrosion properties, etc. Therefore, it is very important to select the right steel wire for your application. In this Blog, we will discuss the difference between Annealed Wire and Galvanized Wire (GI Wire) and which of them is best for your projects.
What is Annealed Wire?
Annealed Wire is a low-carbon steel wire made from Mild Steel Wire (MS Wire). To manufacture Annealed Wire, heat treatment is given to the wire and then slowly cooled down. This heat treatment enhances the physical properties of Annealed wire by making it more flexible and ductile.
What is GI Wire?
GI Wire or Galvanized Wire is manufactured by passing the wire through a hot dip molten zinc solution. The wire is drawn through a series of dies and drums to achieve the desired gauge. After that, the wire is dipped in the molten zinc solution known as the Galvanization Process. It is used to protect the wires from rusting by coating the wire with an extra layer of zinc.
Now let’s discuss the other differences between Annealed Wire and GI Wire:
Anti Corrosion Property –
When we talk about the anti-corrosion properties of Annealed Wire and GI Wire, GI Wire is more resistant to corrosion. A zinc layer is applied on the surface of the wire to prevent it from direct contact with weather. Zinc acts as a barrier between the environment and the wire. It helps protect the wire from rusting. Whereas in Annealed Wire anti anti-corrosion oil layer is applied at the end to protect it from rusting. There is no inbuilt corrosion property in the Annealed Wire. If you need wire for extreme weather conditions then choose GI Wire otherwise Annealed Wire is best.
Manufacturing Process –
The manufacturing of Annealed Wire and GI Wire is similar up to a certain point. After this, they have separate manufacturing steps. The raw material used for the manufacturing of both of them is steel rods e.g. Mild Steel rods or stainless steel rods. After that these rods have undergone the drawing process. In this step, rods are drawn through a series of dies and drums to achieve a desired gauge. Now to make Annealed Wire, the wire undergoes heat treatment at around 840 degrees Celsius for 7-10 hours. After that wire is cooled down slowly. It enhances the physical properties of the wire. To make GI Wire, wire undergoes a Hot dip Galvanization process. In the hot dip galvanization process, the wire is immersed in a bath of molten zinc. The wire surface is coated with zinc to protect it from rusting.
Pricing –
When we compare the price of Annealed Wire and GI Wire, Annealed Wire is more affordable. It is affordable because of its raw material (MS Wire), and its simple manufacturing process. There is no need for extra chemicals and extra setup for its formation. Whereas GI Wire is expensive because of its manufacturing process. So, if you are looking for the best wire under budget then go for Annealed Wire and if there is no limitation of budget then you can choose GI Wire.
Durability –
GI Wire is more durable as compared to Annealed Wire in some applications. GI Wire has an extra coating on its surface which makes it more durable. Annealed Wire is also durable when we apply anti-rust oil on its surface. Annealed Wire is mostly used in indoor applications. So when used properly then they are also durable.
Flexibility –
Annealed Wire is more flexible as compared to GI Wire. This is because of the heat treatment given to Annealed Wire. Annealed Wire is used in a large number of applications because it is easy to bend, and mold without breaking or cracking. Whereas GI Wire is stiffer and not easy to work with. That’s why they have fewer applications as compared to Annealed Wire
Applications –
Annealed Wire is used in binding and tying, the crafting industry, the electrical industry, the automotive industry, and the construction industry as securing reinforcement bars, fences, etc. GI Wire is used in the agriculture industry for fencing or baling, barbed wiring, manufacturing of wire mesh, etc.
In Conclusion, Annealed Wire and GI Wire both have almost the same applications and properties. Which one is best totally depends on its purpose of use. For some applications, Annealed Wire is best while for others GI Wire. If you are looking for the best wire under budget then Annealed Wire is the best choice, as it can become anti-corrosive by just applying a layer over it.
