Carbon Steel Wire Rod, refers to steel that has been hot-rolled in a wire rod mill and then coiled into a coil. Its key features include the following:
1. Unique shape, convenient for transportation and storage

Compared to straight bars, hot rolled wire rod in coiled form can be stacked in large quantities within a limited space, reducing space usage during transportation and storage. For example, Wire Rods with an 8 mm diameter can be rolled into a disc approximately 1.2-1.5 meters in diameter, weighing hundreds of kilograms per disc. This facilitates lifting and long-distance transportation, making it particularly suitable for large-scale industrial distribution.
2. Excellent processability and wide application

Hot rolled wire rod is made from a variety of materials (such as low-carbon steel, high-carbon steel, and alloy steel). After hot rolling, it exhibits excellent plasticity and toughness, making it easy to process. Common processing methods include cold drawing (to produce wire), straightening and cutting (to produce fasteners such as bolts and rivets), and braiding (to produce wire mesh and wire rope). It is widely used in construction, machinery manufacturing, the automotive industry, and metal products.

3. High Dimensional Accuracy and Excellent Surface Quality
Modern Wire Rod Coil mills can precisely control the diameter tolerance of wire rod (typically within ±0.1 mm), ensuring product consistency. Furthermore, controlled cooling and surface treatment during the rolling process produce a smooth, low-scale surface. This not only reduces the need for subsequent polishing but also improves the quality consistency of the final product. For example, the surface quality of high-carbon steel wire rod used in spring manufacturing directly affects the fatigue life of the spring.
