Understanding the Different Types of Garage Door Springs

he springs on your garage door are essential components, responsible for counterbalancing the door’s weight and enabling it to open and close smoothly. When they function correctly, you likely don’t give them a second thought. However, when a problem arises, understanding the type of springs your system uses is crucial for diagnostics and effective garage door spring repair. At Garage Door Services Laurel Florida, we know that knowledge empowers homeowners to make informed decisions about their garage door’s health and maintenance. While all springs serve the same primary function, they operate differently and have distinct characteristics.

The Two Main Categories of Garage Door Springs

Most residential garage doors use one of two types of spring systems: torsion springs or extension springs. Identifying which kind you have is straightforward. Torsion springs are typically mounted horizontally on a metal shaft above the garage door opening. Extension springs, on the other hand, are located on both sides of the door, running parallel to the horizontal tracks. Each system has its own method of operation, lifespan, and safety features, making one more suitable than the other depending on the door’s size, weight, and usage.

Torsion Springs Explained

Torsion springs are the more modern and common standard in the industry today. This system uses one or two tightly wound springs on a steel shaft with cable drums at each end. As the door closes, the cables attached to the bottom of the door cause the springs to wind up, which creates and stores torque, or rotational energy. When you open the door, these springs unwind and release that energy, helping to lift the door’s heavy weight. Torsion springs generally provide better balance, a smoother motion, and last longer than extension springs. They are also considered safer because if a spring breaks, it typically stays contained on the shaft.

A Look at Extension Springs

Extension springs are an older but still widely used technology. These springs are mounted on the sides of the garage door and are attached to a pulley and cable system. Unlike torsion springs that twist, extension springs stretch and contract to counterbalance the door. As the door lowers, the springs extend, storing potential energy. When the door opens, the springs retract, pulling the door upward. Because they are under high tension and move freely, extension springs must have a safety cable running through them. This cable is a critical feature that prevents a broken spring from flying across the garage and causing injury or property damage.

Knowing whether your system uses torsion or extension springs is the first step in proper care and maintenance. Each type has unique signs of wear and requires a specific approach for adjustment or replacement. If you suspect an issue with your springs or are unsure about your system, it’s always best to rely on professional expertise.
