Precision Engineering, Custom Solutions — 28+ Years of Cold-Drawn Steel Manufacturing Excellence

Cold-drawn steel is produced by pulling through precision dies at room temperature, achieving dimensional tolerances as tight as ±0.03mm—far superior to hot-rolled steel's ±0.5mm or looser tolerances. This high precision eliminates or significantly reduces secondary machining, directly saving production costs and time.

Additionally, the cold-drawn process creates a bright, smooth surface without scale or oxidation, making it ideal for precision machinery parts and automotive components that demand strict appearance and fitting accuracy.

The work hardening effect during cold drawing increases tensile and yield strength by 20%-30% while maintaining good ductility. This makes cold-drawn steel ideal for producing gear shafts, guide rails, suspension parts and other components subject to heavy loads and cyclic loads.

The cold-drawing process aligns steel grain structure more uniformly, resulting in excellent straightness and consistent mechanical properties throughout the entire length. This ensures stability in CNC machining and assembly while reducing rejection rates.

In contrast, hot-rolled steel is prone to warping and hardness variations due to uneven cooling.

The precise dimensions and smooth surface of cold-drawn steel significantly reduce tool wear, enabling faster and more efficient machining. This shortens production cycles, extends tool life, and lowers overall production costs.

Cold-drawing technology can produce square, hexagonal, rectangular, and custom profile steels with strict tolerances, meeting individualized design requirements—an advantage that hot-rolling cannot easily match.
