Torsion springs are mounted horizontally above the garage door and are known for their durability and smoother operation. These springs wind and unwind to balance the door's weight, providing a controlled and reliable lifting mechanism.Torsion springs come in left-wound and right-wound variants, depending on the direction of the wind. Ideal for heavy doors and high-cycle applications, torsion springs are considered safer than extension springs, as they are installed above the door, minimizing exposure.
Extension springs are mounted on either side of the garage door and expand and contract to facilitate door movement. When the door closes, extension springs stretch, storing energy. When the door opens, this energy is released to assist in the lifting process. It's common to use safety cables with extension springs to prevent them from becoming projectiles in case of breakage. Suitable for lighter doors, they have a visible stretch and contraction during operation. Extension springs require more maintenance and safety precautions due to their side-mounted positioning.
High-cycle springs are designed for durability and are engineered to withstand a higher number of open-close cycles. They are available in both torsion- and extension-spring types. Extended lifespan, making them suitable for busy garages or commercial applications. Similar to standard torsion or extension springs, with a focus on selecting high-quality replacements for enhanced durability.
