Bulk Torsion Spring Coils – A Cost-Effective Option for Manufacturers

Bulk torsion spring coils are an efficient choice for manufacturers who need to produce custom torsion springs for garage doors, industrial doors, and roller shutter systems. Rather than buying pre-cut springs, many OEMs prefer full-length coils that can be processed according to their own requirements.

These coils are made from ASTM A229 high-carbon steel and formed using CNC coiling equipment to ensure uniform pitch and smooth surface quality.
Long-length spring material helps reduce waste, improve inventory flexibility, and lower production costs for factories.

We supply coils in multiple wire diameters and can provide optional surface finishing such as black-oil, galvanized, or powder-coated.
