Which Are the Main Types of Garage Door Springs?

Types of Garage Door Springs

Springs are among the most fundamental components of your garage door. Unfortunately, they’re among the most overlooked components as well. That’s why today we’ll show you what are the different types of garage door springs.

In most cases, if your garage door starts to experience problems while opening and closing, then it’s very likely that your springs have gone bad. For this reason, you should know of their main function and why are they so important for your garage door.

2 Main Types of Garage Door Springs You Should Know Of

Generally speaking, there are two main types of garage door springs: extension springs and torsion springs. Garage door extension springs add support from the sides of the garage door. Standard torsion springs, on the other hand, hold the garage door from above and tend to last longer as well.

Let’s take a better look behind the types of springs:

Garage Door Extension Springs

Extension springs are the traditional option for when it comes to residential garage doors due to its affordability. As stated before in this blog, these springs are set at both sides of the door, along the horizontal tracks. 

For both automatic and manual doors, these springs extend and contract in order to counterbalance the garage door’s weight. If you opt for extension springs, you’ll want to have safety cables installed as well. The reason for this is to help prevent the extension springs of becoming a real danger in case the spring breaks. 

How Do Extension Springs Work?

Think of extension springs as a trampoline. When a garage door closes, it causes tension in the spring, just like a trampoline would do. However, instead of the springs returning to their original compressed state, they remain extended. This helps store energy for the next time you use your door. As a result, when you open the door, the spring pulls it by using the stored energy.

Due to the fact that they are smaller compared to torsion springs, they work best when having a low-ceiling garage. 

Extension Spring Measurements and End Types

When looking for extension springs, there are many things you need to keep in mind. For instance, you’ll want to know the exact measurements and end types that’ll best suit your garage door type. Not only that, but it’s also vital for homeowners to keep in mind how much weight the spring can hold. 

Usually, 25-inch springs go well with garage doors that are 7 feet. In case you count on a garage door that’s 8 feet, then you should go for a 27-inch spring. When assessing your garage door, make sure to make precise measurements.

Besides length and weight, you should also know which are the end types that will work best for you. There are three end types for extension springs: single open loop, double closed-loop, and clipped ends.

Single open looped are for light-weight garage doors, such as fiberglass doors. Then, we have double closed-looped doors, which are for mid-weight options. Lastly, clipped loops are for the heaviest garage doors.

Extension Spring Color Codes

Lastly, it’s vital to keep in mind which are the color codes for extension springs, since they tend to differ from the torsion springs’ color code. This coding system is set by the Door & Access Systems Manufacturers Association (DASMA).

For extension springs, their color is set according to the weight they’re meant to withstand and counterbalance. Also, be sure to use color codes as an aid when choosing extension springs, alongside with the info your door manufacturer can provide you.

Garage Door Torsion Springs

Now that you know what extension springs are, it’s time to know the other type of garage door springs. Torsion springs are on a long shaft that’s above your garage door, instead of the sided. They work by using a stretch or torque action to open and close your door. Compared to extension springs, torsion springs tend to last much longer.

How Do Torsion Springs Work?

When springs torque, they rotate and twist. This rotation causes the metal shaft to coil up and store energy. However, unlike extension springs, torsion springs can store up much more energy. Because of this, your garage door lifts more efficiently.

Because the springs are at the shaft, they count on cables that make the torsion springs unroll when you close the door and roll up when you open the door. Due to the springs’ stored energy, your garage door closes without slamming onto the floor.

There are some factors that can make torsion springs wear out quicker. Such factors include cold and humid climates, as well as the quality of your spring’s material. 

Whenever you need to change your torsion springs or you start to notice any alarming signs on your garage door opener, be sure to call a professional garage door repair company. That way, you’ll keep yourself and your garage door out of harm’s way.

Types of Torsion Springs

Usually, torsion springs come in five styles:

  1. Standard commercial and residential
  2. Torquemaster
  3. Mini-warehouse
  4. Steel rolling door
  5. EZ-SET 

The first type of torsion spring is the traditional option for garage doors. If your garage door is light, then you’ll only need one of this torsion spring type. If your garage door is on the heavier side, however, you might need your torsion spring to be on a spring anchor bracket. That way, you can set more than one spring to distribute the weight.

Torquemaster torsion springs count on one to two springs that are attached by a stationary cone. EZ-SET, on the other hand, has a simpler mechanism compared to the torquemaster by having its winders set onto the shaft ends.

When it comes to warehouse garage doors, we have two types of torsion springs: mini-warehouse and steel rolling door springs. Steel rolling springs are not for sectional doors. These are for slat garage doors instead. 

Finally, mini-warehouse springs, alias self-storage springs are the ideal option for one-piece curtain doors. 

Torsion Spring Color Codes

Lastly, you need to know torsion spring color codes vary from those used on extension springs. While extension spring colors are set according to the weight they can counterbalance, torsion spring colors are set according to the wire gauge size.

Now that you know the main types of garage door springs and their main differences, it’s time for you to make the decision in which one is best for you!
