Torsion and
Extension Springs

Torsion springs and extension springs play integral roles in many homes and businesses. Often, they assist with door closure, particularly in the case of garage doors. These two types of springs operate differently, however, so it is important to understand these differences before you place your order.

How Torsion Springs Operate

When you think of a spring, you probably think of a metal coil that expands and contracts under changing pressure. A torsion spring is a bit different because rather than stretching and contracting, the metal coils actually turn. This makes them incredibly sturdy, improving their life span. Top-quality torsion springs last up to 20,000 cycles while extension springs generally last 10,000. Many individuals prefer torsion springs in most applications because they provide a controlled motion rather than jerky movements or quick changes in tension.

How Extension Springs Operate

On the other hand, extension springs operate by expanding and contracting. The coils separate from one another and then move close together again, acting as a counterbalancing force of sorts, and this movement is typically required for garage doors and similar applications. However, extension springs have a shorter lifespan, and they often require more parts, such as sheathes and extra safety cabling. Extension springs are usually the cheaper option, but that does not always make them the best option.

The Most Common Application

Torsion and extension springs are found most often in residential garage door installations, so if you are installing a garage door, you will need to decide which of the two types of springs is best for you. Bear in mind that while extension springs are cheaper and more common, torsion springs are safer and require far less maintenance. The latter option provides smoother movement, too. Over time, extension springs expand and contract, causing wear and tear. The unexpected breakage of an extension spring can cause damage to person and property; for this reason, the right safety precautions are necessary.

Choosing the Right Spring

Extension springs are cheaper, so they make up the majority of most consumer purchases – particularly in garage door applications. It is important to ensure that all of the proper safety cables and sheathes are in place. On the other hand, although tension springs are more expensive, they last almost twice as long and they are safer. They are less likely to break violently, even when worn, and they require fewer parts during installation. Regardless of the type of spring you choose for your installation, make sure it is of high quality and backed by a guarantee. The quality of your garage door or other installation is only as good as the quality of the spring that operates it.
