Torsion Spring Applications
Torsion springs are a critical component in sectional garage doors, providing the balanced torque necessary to lift and lower heavy door panels with minimal effort. Unlike standard springs, they offer consistent performance, long service life, and smooth operation—especially important in residential, commercial, and industrial garage door systems where safety and reliability are key. Their precise tension adjustment ensures the door remains stable, even under frequent cycles.
