What is galvanized steel strand?

Galvanized steel strand

Galvanized steel strand has become an indispensable material in construction, transportation, electricity and other fields with the development of modern science and technology. Steel strands are used in a wide range of applications, such as in the support systems of large buildings and bridges, and can also be used to protect oil pipes or pipelines after being buried underground. Among them, galvanized steel strand is the common type of steel strand. This article will discuss in detail its advantages and the selection method of winding.

Definition of galvanized steel strand

Galvanized steel strand is a steel product made of high-quality steel wire as the main material, with a layer of zinc electroplated on the surface of the steel wire to improve the corrosion resistance of the steel strand, and multiple galvanized steel wires are twisted together. Therefore, this material has high corrosion resistance and can be used in harsh environments. It has high strength, corrosion resistance, wear resistance and other characteristics. It is widely used in construction, bridges, foundation engineering, ships, mines and other fields.

Characteristics and uses of galvanized steel strand

In the field of construction, steel strands are used for prestressing concrete structures, which can improve the load-bearing capacity and durability of concrete; in the field of bridges, steel strands are used for the reinforcement and maintenance of bridges; in the field of mining, steel strands Wires are used for reinforcement in coal mine shafts and for rotational support of shearers.

1.High strength

Galvanized steel strand is made of multiple strands of fine galvanized steel wires twisted together. It has high strength and can withstand large pulling forces.


The surface of the steel strand has been treated with galvanizing, etc., which has good corrosion resistance and can be used in various harsh environments.

3.Wear resistance

Steel strand has good wear resistance and can be used in harsh environments for a long time.


Steel strands can undergo deformation processing such as bending and torsion, and are not easy to break.

5.Various specifications

Steel strands have various specifications, and different specifications can be selected according to different usage occasions.

Galvanized steel strand winding method

1.Single twist type: Single twist type is to wind the steel wire into a steel strand with a low twist degree at one time.

2.Compound twisting type: Compound twisting type is twisted on the basis of single twisting.

Compared with single-stranded steel strands, compound-stranded steel strands have stronger mechanical properties and torsion resistance, and are more suitable for use in large bridges and support systems.

The winding method of galvanized steel strand also involves the diameter and strength of the steel wire.
Generally speaking, steel strands made of steel wires with larger diameters and higher strengths are stronger and more suitable for use in areas that bear large loads. Strands made of steel wires with smaller diameter and lower strength are used in areas that support light loads and have a certain degree of flexibility and torsion.

It has good performance and application prospects. As an important building material, it has been widely used in various fields. In the manufacture and use of steel strands, scientific, safe and reliable methods are very important. Zhengzhou Jinshui Cable Group ensures the quality and safety of galvanized steel strands on the basis of continuous technological innovation and continuous improvement of management processes. Performance is optimal.
