Functions Of Cold-drawn Steel Wire

The main functions of cold-drawn steel wire include increasing strength, saving materials, improving performance and adapting to specific engineering needs. Cold-drawn steel wire is made by stretching ordinary hot-rolled steel bars at room temperature. This process can significantly increase the yield strength and tensile strength of the steel bars, making them stronger than untreated steel bars. Specifically:

Increase strength: After cold-drawing, the yield point and tensile strength of the steel bars are significantly improved, usually by 25% to 30%, thus meeting high-strength requirements.

Save materials: Since cold-drawn steel wire has higher strength, the use of cold-drawn steel wire can reduce the amount of steel bars under the same bearing capacity requirements, thereby saving material costs.

Improve performance: Cold-drawing can also improve the surface quality and dimensional accuracy of the steel bars, enhance the bonding performance between concrete and steel bars, and further improve the overall stability and durability of the structure.

Adapt to specific engineering needs: Under some special conditions (such as long-span bridges, high-rise buildings, etc.), when there are higher requirements for material strength, choosing cold-drawn steel wire can better meet the needs of these projects.
‌Convenient construction‌: The cold drawing process is relatively simple and easy, which is convenient for large-scale production and on-site processing and installation‌.
In addition, cold-drawn steel wire also has the functions of straightening steel bars, automatic rust removal and welding quality inspection‌. Through cold drawing, the texture of the steel bars becomes more uniform and the strength is consistent. At the same time, the surface rust automatically falls off and the steel bars are straightened‌.
