Different Types Of Garage Door Springs
For garage doors to function properly, there are many key parts that must always be in tune and that includes garage door springs.
What You Need To Know About Garage Door Springs
There are two main types of garage door springs used in the installation and operation of garage doors, extension springs, and torsion springs.
Here is a breakdown of how these garage door springs have their own purpose, offer different functions, and have different costs associated with them:
The most common garage door springs are called a torsion spring. While an extension spring extends to perform its function, torsion springs use torque to perform its function. These springs are sturdy and generally last longer than other kinds.
Torque is a twisting force that causes rotation. So, when the force of the garage door opening or closing is applied (by hand or motor), the coil twists and coils on the shaft.
A torsion spring comes in various lengths and sizes, and the spring you use is determined by the size and opening dimensions of the garage door.
Extension springs are normally found in the upper, horizontal tracks on each side of the garage door. These are commonly used when there is low headroom, making it unable to apply rear torsion springs.
To open the garage door, the springs are extended, creating a counterbalance which supports the garage door. The more the door is open (and the springs are extended), the more force is placed on the extension springs.
With this amount of force on these heavy-duty garage springs, there must be safety measures included in the installation. In the case of these springs, each extension spring is paired with a safety cable.
If there is a malfunction and the spring breaks free, the safety cable will prevent it from shooting freely, which can cause serious harm. The safety cable also protects homeowners if a cable or bracket fails.
It is essential that these safety cables remain in place at all times. This includes any time the door is open, closed, or in motion, as there is a risk of the spring breaking free.
Extension Vs. Torsion – Is One Garage Door Spring Better Than The Other?
Both types of springs are under tremendous force and they each coil or recoil in their own way. This means each of these garage door springs must be well taken care of.
Extension springs tend to be less expensive, and they are often used in residential applications. Because they cost less, many builders use them in new home construction. They are functional and ultimately, cost-effective. While the initial investment is lower, the life of an extension spring versus a torsion spring is much shorter.
Torsion springs have fewer exposed parts, making them safer. They last longer and smoothen the opening and closing of your garage door. However, your initial investment will be greater. They cost more because they last longer.
If you are repairing your garage door, adding to your garage, or thinking about upgrading your garage door opener, consult with a professional garage door repair company to determine which of the different types of garage door springs is better for you, your family, or your business.
