Garage Door Torsion Spring Chart

Torsion springs are an essential part of any garage door system, providing the power to lift and lower the door smoothly and safely. Choosing the correct torsion spring size is crucial for optimal performance and safety. This Garage Door Torsion Spring Chart provides a comprehensive guide to help you determine the appropriate spring size for your garage door.

The key factors to consider when selecting a torsion spring are the door weight, height, and wind load. The door weight is typically determined by its size and the material used. The door height is important because it affects the leverage of the springs. The wind load is a factor that should be considered for areas where high winds are common.

To use the chart, simply locate the intersection of the door weight and height. The corresponding value represents the recommended torsion spring size. For example, for a door that weighs 150 pounds and is 8 feet tall, the recommended torsion spring size is 0.250 inches.

It is important to note that this chart is for standard garage doors. If you have a custom or non-standard garage door, it is recommended to consult with a garage door professional to determine the appropriate torsion spring size.

Here is a more detailed explanation of the factors to consider when selecting a torsion spring:

Door Weight

The door weight is the most important factor to consider when selecting a torsion spring. A spring that is too weak will not be able to lift the door properly, while a spring that is too strong will put unnecessary stress on the door and its components.

Door Height

The door height affects the leverage of the springs. A taller door will require a stronger spring than a shorter door of the same weight.

Wind Load

The wind load is a factor that should be considered for areas where high winds are common. A spring that is too weak may not be able to withstand the force of the wind, which can cause the door to blow open.

By following the guidelines in this Garage Door Torsion Spring Chart, you can select the correct torsion spring size for your garage door. This will ensure that your garage door operates smoothly and safely for years to come.
