A very key component of garage doors is the spring. Unfortunately, most homeowners pay little attention to it until a fault develops, impeding the functionality of the entire door. While there are different spring types to be selected from, two categories are most common – torsion and extension springs – with several distinguishing features. Let’s examine both of them in details:
- Torsion Springs: They are installed above the garage door. It functions whenever force is applied, through the twisting motion of the spring into a shaft to which the lifting cables are attached. There are different types of torsion springs which are dependent upon the weight, height and track radius of the garage door.
- Extension Springs: They are normally installed above the upper horizontal tracks on both sides of the garage door. The extension spring system provides a counterbalancing force on the expansion of the spring due to the force applied to raise the door, the spring also contracts when force is withdrawn to lower the door. All extensive spring doors are held in place by safety cables to prevent injuries and damages in the event of a spring breaking apart.
Considering a broader perspective, as earlier stated, there are different types of torsion springs with variations in the number of springs and purpose.
- TorqueMaster Torsion Springs: This option is highly safe to use. It uses a two-spring system contained in as shaft and a winding cone on the opposite end. The presence of a special winder also allows the spring to be wound with an electric drill.
- Standard Torsion Springs: It is a common residential door spring type which is normally secured in a spring anchor bracket. The spring works with a shaft which is about 1inch in outside diameter. Torsion springs of this type are usually used in pairs to ensure strength and safety.
- Standard Commercial Torsion Springs: This type of system uses four or more torsion springs and is usually found with commercial doors. The multiple springs provide more safety and strength and the setup can be one of linear, duplex, triple or mixed systems.
- EZ-set Torsion Springs: Its uniqueness lies in the extra parts which are: a winder and white plastic shaft retainer that works together with the shaft held next to the cable drum. The EZ-set springs are mounted to the winders placed at either end of the shaft. This type of torsion spring system is mainly used in two-car garages.
- One-piece Curtain Door Torsion Springs: It is mainly used in self-storage locations. The spring ends are secured to one of the drums.
- Steel Rolling Door Torsion Springs.
Before making a choice between a torsion spring and extension spring door system, you might want to consider the strength, safety, and pricing of both options.
While the extension spring is cheaper, the extra parts in a torsion spring system takes the price higher although it is potentially cheaper considering its durability. On safety, the torsion spring is positioned in a shaft and hence safer option compared to the extension spring which is exposed and could be potentially dangerous. Finally, the torsion spring provides more balance and moves smoothly while the extension spring sometimes moves jerkily predisposing the parts to occasional wears and tears.
