Torsion springs operate on the principle of torque, twisting and storing energy as they wind up under tension. When the garage door is closed, torsion springs are wound tightly, storing potential energy. As you manually or automatically open the door, the springs release their stored energy, unwinding and aiding in lifting the door. The release of energy from torsion springs occurs in a manner that is controlled, and ensures a steady and balanced movement, preventing sudden jerks or uneven motions. These springs are commonly found in sectional and one-piece tilt-up garage doors.

Now let’s discuss extension springs, which function through their ability to stretch and contract. When the garage door is closed, these springs are under tension, elongating to hold the door in place. As the door is lifted, extension springs contract and release stored energy, and this helps to lift up the garage door. Extension springs are often mounted parallel to the horizontal tracks on either side of the door and are frequently used in one-piece tilt-up and some sectional garage doors.

The choice of spring type in a garage door depends on factors such as the door's weight, size, and design. Torsion springs tend to offer control over the door's movement and smooth functioning. They might be used in sectional garage doors, which comprise multiple horizontal sections that roll up vertically. Extension springs, while simpler in design, are used in one-piece tilt-up doors or some sectional doors where their stretching and contracting motion complements the door's opening mechanism.
