Cold drawn SM/SH

Our SM/SH wire grades are engineered for springs that require consistent performance in medium to high static load environments, offering a spectrum of mechanical resistance to meet rigorous demands.

Cold-drawn wire is a high-strength material produced through a cold-working process, manufactured in accordance with current international standards, including EN 10270-1, ASTM 228, and JIS G3522 . Our standard wire shape is round, with other shapes like square or rectangular wire also available. This wire offers exceptional tensile strength, along with production using state-of-the-art processes suitable for both static and dynamic applications.
