Q235 is an ordinary carbon structural steel (by the GB/T 700 standard), belonging to low-carbon steel (with a carbon content of 0.14% - 0.22%). "Q" stands for yield strength, and "235" indicates a yield strength of ≥ 235 MPa (applicable to steel wires with a diameter of ≤ 16 mm). As the size increases, the yield strength gradually decreases. The Q235 carbon steel wire, with its excellent balance of strength and plasticity, outstanding weldability, and low cost, has become a universal material in fields such as construction, machinery, and transportation.
Form: Usually made from hot-rolled wire rods, it is processed through cold drawing to produce steel wires. It is one of the main types of low-carbon steel wires (the other type is Q195).

Production Process:
Bill preparation: Select the appropriate billet to ensure that its chemical composition meets the Q235 standard.
Heating treatment: Heat the billet to an appropriate temperature to improve its plasticity.
Rolling: Roll the billet into a steel wire of the required diameter through multiple rolling passes.
Annealing: Annealing treatment is performed to soften the material and improve its processing performance.
Surface treatment: Surface treatment, such as galvanizing, painting, etc., is performed according to requirements to improve corrosion resistance.
Inspection and packaging: Quality inspection of the finished steel wire is carried out to ensure that it meets the standards before packaging.
