Wire refers to hot-rolled round steel with a diameter of 5-22 mm or shaped steel with a cross-section equivalent to this. Since it is delivered in rod form, it is also commonly known as rod.
The cross-sectional perimeter of the wire is very small, and the common product specifications have a diameter of 5–13 mm. Depending on the rolling mill used, it can be divided into high-speed wire (high-speed wire) and ordinary wire (ordinary wire). The wire is mainly used forsteel rebarReinforcement of concreteWelding structureRaw materials for processing or further treatment (such as wire drawing, nail making, etc.). According tosteelAllocation directory; wires include ordinary onesLow-carbon steelHot-rolled wire rods, welding wire rods, blasting wire rods, heat-treated wire rodsThreadingRod, high-quality rod.

Crude steelThe production growth rate is roughly stable at around 20%, but it slowed down in 2007 to 13.8%. The total volume increased nearly twice that of 2003. Looking at the import and export of wire rods, wire rods have long been a major steel product for export in China, maintaining a net export status, especially with rapid growth in recent years. In 2007, China exported 63.38 million tons of wire rods, an increase of 68.4 million tons compared to the previous year, representing a 12.3% year-on-year growth; imports were 61.4 million tons, a decrease of 9.1 million tons compared to the previous year. Regarding domestic consumption of wire rods, they are widely used in the construction sector. Since 2000, driven by strong domestic investment demand, domestic consumption of wire rods has also seen rapid growth.
