Galvanized Wire Rope: Manufacturing, Chemical Properties, & Uses

Galvanized steel is produced by coating carbon steel with a protective layer of zinc. To form galvanized wire rope, carbon steel wires are immersed in molten zinc and then cooled, forming galvanized steel wire. The newly formed galvanized steel wire is then fed into a stranding machine, where it is helically stranded to produce galvanized steel wire rope. Due to its excellent breaking strength, durability, and relatively low cost compared to its stainless steel counterpart, galvanized wire rope is a common choice in construction, agriculture, and manufacturing industries.

You can find more information on our web, so please take a look.

To characterize galvanized steel wire rope's break strength, let's look at Sava's cable. With a diameter of 3/8 inches, it boasts a breaking strength of 14,400 lbs.

Galvanized steel's durability is thanks to its aforementioned zinc coating. This coating acts as a barrier, protecting galvanized steel's vulnerable carbon core from wear and tear, moisture, and other corrosive elements that are often present in the final application's environment.

While galvanized steel is water-resistant, it can corrode in saltwater due to chloride ion reactions. This reaction causes the coating to erode, thus exposing the underlying carbon steel. Stainless steel, which is naturally resistant to corrosion due to its lower carbon content, offers greater resistance to saltwater. However, due to its chemical makeup and a less demanding manufacturing process, galvanized steel is more cost-effective than stainless steel, making it more suitable for applications where harmful environmental factors are limited.

The Chemical Composition of Galvanized Steel

We've mentioned that galvanized steel is produced by coating carbon steel with a protective layer of zinc. However, there are many varieties of carbon steel, including high-carbon steel and low-carbon steel, and the selection of the carbon steel influences the galvanized steel result. High-carbon steel is defined as steel with a carbon content of 0.6-1.0%, while low-carbon steel, which contains up to 0.25-0.3% carbon. Galvanized steel generally consists of low-carbon steel as the substrate, due to its better formability and ease of coating with zinc compared to high-carbon steel.

In addition to selecting the low-carbon steel, the chemical composition of the carbon steel must be considered to properly apply zinc coating.

What is galvanized steel wire and what are its common uses?

Galvanized steel wire can be considered as a very important product used in all construction works. What is galvanized steel wire? Why is it commonly used in everyday life?

In the article below, we invite you to join MRS Steel to learn basic information as well as common applications of galvanized steel wire.

What is galvanized steel wire?

What is galvanized steel wire? Galvanized steel wire is a type of steel wire that has a shiny white color, high toughness, and durability and is a product widely used in the fields of electricity, industrial production, and construction. Galvanized steel wire is usually produced from low-carbon steel through a process of heating and drawing into wire. Galvanized steel wire is usually very small in size, thin, and rolled into large coils for easy transport. Galvanized steel wire features a smooth or ribbed surface, with average production diameters from 0.4mm to 14mm. The average weight of a roll of galvanized steel wire usually ranges from 200 to 459 kg/roll.

Classification of galvanized steel wire

The above section has given you information about what is galvanized steel wire? Next, we invite you to learn about the popular types of galvanized steel wire.

Currently, galvanized steel wire is classified based on the galvanizing method. Therefore, galvanized steel wire is divided into two main types: hot-dip galvanized steel wire and electrolytic galvanized steel wire. Currently, zinc plating is produced with matte or gloss plating technology according to standards TCVN , JIS G305, ASTM A475 or according to customer requirements. For everyone to better understand these two types of galvanized steel wire, please follow the classification table below.

Advantages of galvanized steel wire

Galvanized steel wire is increasingly used not only in the construction industry but also in other industries. So why is galvanized steel wire so commonly used? Let's find out below.

  • High applicability: Galvanized steel wire is used in many industries such as construction, handicrafts, industry,...
  • Corrosion resistant: The outer galvanized layer increases the oxidation resistance of the steel wire, making it difficult for the steel wire to corrode and extending the product lifespan.
  • Low cost: The cost of galvanized steel wire is often cheaper than aluminum or copper wire. Therefore, they often bring lasting economic value to users.
  • Long lifespan: Galvanized steel wire has a lifespan of over 50 years in normal weather conditions and 20–25 years in environments with many corrosive substances, such as industrial parks, coastal areas,...

Application of galvanized steel wire

As an essential material in the construction field, along with serving human life, galvanized steel wire is found almost everywhere around us. Here are a few applications of galvanized steel wire:

  • Application in the construction industry: Mainly widely used in the construction industry, such as reinforcing houses, apartments, swimming pools,...
  • In civil use: used to bind goods, make barns for the livestock industry,...
  • In production: used to weave types of mesh such as chain-link fencing, welded steel mesh,...
  • Also used in industrial production, handicrafts, and other fields.
