Everything about Cold-drawn steel wire

Cold-drawn steel wire is a type of industrial steel wire known for its wide range of applications across various sectors. This wire is manufactured from high-carbon steel rods that undergo a cold drawing process after initial hot-rolling and patenting heat treatment around 900°C. It’s available in two main types: regular and strip-shaped, and is supplied to the market in both coils and straight lengths (bars).

What are the specifications of Cold-drawn steel wire?

Cold-drawn steel wire are a type of steel wire produced from hard industrial wires heated to 900 degrees Celsius and baked. This wire is supplied to the market with a diameter of 1.2 to 1.7 mm, a length of 6 meters per bar, and a weight of 25 to 30 kg, in black color.

High flexibility and tensile strength make this wire a suitable choice for various applications. Among these applications are rebar tying in the construction industry, securing concrete molds, book and pamphlet binding, packaging of goods, production of various types of mesh, and artistic uses.

 

Cold-drawn steel wire despite their affordable price, offer other advantages such as high strength, flexibility, and weldability. However, it should be noted that this type of wire is not resistant to moisture and rust, and has a higher weight compared to galvanized wires.

Advantages of Cold-drawn steel wire

The first and most important advantage of this wire is its affordable price. Cold-drawn steel wire has a more suitable price compared to other metal wires such as galvanized wire, stainless steel wire, and aluminum wire. The reason for this stems from several key factors:

• Production process: Black wires are produced through a simpler process using cheaper raw materials such as low-carbon steel. In contrast, producing other wires like galvanized wire requires more complex processes and more expensive raw materials such as zinc metal.
• No need for coating: Unlike galvanized and aluminum wires, black bar wires do not require an anti-rust coating. This is due to the presence of iron oxide on the wire’s surface, which acts as a protective layer.
• Less waste: In the production process of black bar wire, less waste is generated. This is due to the use of high-quality raw materials and a more optimized production process.
• Production diversity: Black bar wire is produced in high tonnage with a variety of thicknesses and lengths. This fosters competition among manufacturers and reduces the final product price.
• Wide range of applications: Cold-drawn steel wire is used in various industries. This leads to increased demand and, consequently, a reduction in the final product price.

High flexibility and resistance

Cold-drawn steel wire possesses high tensile and flexural strength. Additionally, due to its high flexibility, this wire can be easily bent and shaped.

Summary

In general,Cold-drawn steel wire, despite their reasonable price, offer numerous advantages such as high resistance, flexibility, and weldability. This type of wire is used in various industries and is considered an ideal choice for diverse applications.
