Key Advantages of Our Custom Anti-Theft Door Lock Torsion Springs
Premium Raw Material for Long Service Life
Our door lock torsion springs are mainly made of high-carbon steel, music wire and 65Mn manganese steel, featuring high tensile strength, strong fatigue resistance and stable torsion reset performance. Even after tens of thousands of opening and closing cycles of anti-theft door locks, the spring will not deform or fail, effectively avoiding lock jamming, handle reset failure and other common lock faults caused by spring aging.
Full Customization to Match All Types of Door Lock Structures
We offer full customization on wire diameter, coil turns, inner/outer diameter, torsion arm bending angle, torsion torque and surface finish. Our custom lock torsion springs perfectly fit most household anti-theft door locks, interior wooden door locks, commercial office security locksets, cabinet locks, padlocks and building hardware lock accessories. You can provide your lock sample or technical drawing for exclusive spring development.
Multiple Surface Treatments for Anti-Rust & Corrosion Resistance
To adapt to indoor, outdoor, humid and corrosive use scenarios of security door locks, we provide black oxide, zinc plating, nickel plating, oil spraying and other surface treatment options for door lock torsion springs. Effectively prevent rust and oxidation, greatly extending the service life of the lock spring in long-term frequent use.

Every batch of our anti-theft door lock torsion springs undergoes torsion fatigue testing, dimensional inspection and surface quality screening before delivery. We eliminate defective springs to ensure stable and consistent product quality. Without middlemen, we supply lock hardware distributors, lock manufacturers, hardware repair stores and door lock maintenance companies worldwide with cost-effective factory direct sales.
