Our special-shaped spring steel wire is custom profile wire produced by precision cold rolling and drawing. Unlike conventional round wire, it adopts non-circular cross-section to optimize stress distribution, save material and improve the space utilization of finished springs. We provide oil-tempered and cold-drawn special profiles, available in multiple steel grades. Strict dimensional tolerance control ensures consistent performance for mass spring production.
