We work with: High-carbon steel (Grade 65Mn/70Mn) – most common for industrial use Stainless steel (301/302/304/316) – corrosion resistance Alloy steel (50CrV/55CrSi/60Si2Mn) – high-temperature resistance Custom materials (available upon request)

A torsion spring stores energy and exerts rotational (torque) force through its legs when twisted. GL Springs manufactures custom single and double torsion springs to your exact torque, leg angle, and dimensional requirements — for hinges, levers, latches, and countless rotating mechanisms.
