Torsion & Extension Springs explanation
- Torsion Springs:
- Functionality: Torsion springs are mounted horizontally above the garage door opening on a metal shaft. When the door is closed, the torsion springs coil tightly, storing energy. As the door is opened, the springs unwind, releasing the stored energy to help lift the door.
- Construction: Typically made of hardened steel, torsion springs are available in various sizes and strengths to match the weight and size of the garage door. They feature stationary cones at one end and winding cones at the other for adjustment and tensioning.
- Advantages: Torsion springs offer smoother operation, longer lifespan, and better safety compared to extension springs. They are also suitable for heavier garage doors and require less space for installation.
- Extension Springs:
- Functionality: Extension springs are installed vertically on both sides of the garage door, parallel to the tracks. When the door is closed, the extension springs stretch to support the weight of the door. As the door is opened, the springs contract, releasing tension to help lift the door.
- Construction: Made of tightly coiled steel, extension springs feature safety cables to prevent injury or damage if the spring breaks. They are available in various lengths and tensions to accommodate different door sizes and weights.
- Advantages: Extension springs are simpler in design and installation, making them more cost-effective for lighter garage doors. They also require less maintenance and adjustment compared to torsion springs in some cases.
