Which Steel Rolling Door Torsion Spring Do You Really Need?

Bothered by the torsion spring on your steel rolling door? If you wish to know the working of garage door torsion spring system and also to know which steel rolling door torsion spring is ideal for you, then this article is meant for you!

Measuring the Torsion Springs 

There are generally 5 characteristics of broken torsion springs, which you need to determine before purchasing a new one. You need to measure the wire size and length of the spring, identify the type of ends of the spring and also measure its internal diameter and wind. 

Wire Size and Length

In order to determine the wire size of your spring, you are required to measure the length of the coils. In case your spring is gapped to prevent the coils from binding, you need to compress the spring to carry out the measurement.

You again need to compress the spring to determine its exact length. The length of the spring can be defined as the distance from the last coil at one end of the spring to the last coil at the other end.

Diameter and Shape of Torsion Spring 

Usually, the inside of the spring cone contains markings describing its inside diameter. In case you are unable to locate these markings, you can simply measure the space inside the coils. Also your torsion spring would either be right or left wind.

Lastly, you need to determine the shape of the torsion spring at its ends. If some ends of the spring wrap into the spring cones than you need to order special straight ends and heat the wire to wrap it into the cones. In case your torsion springs end with a loop, then order steel rolling door loops.
