Various Types of Garage Door Springs
From the standard residential torsion springs to industrial torsion springs, extension springs, self-storage roll-up door springs, and more, you may be overwhelmed by the names and various types of springs needed for the safe operation of your garage. To help you out, just know that there are two main categories of garage door springs, extension springs, and torsion springs. And, what a garage door spring is designed to do is act to counterbalance the weight of the door, making it easier to open and close. Just as an example, if your garage door weighs 12 pounds, then you’ll need a spring with enough force of 150 pounds to pull against the weight of the door.
Garage door torsion springs are attached securely to a metal shaft that’s above your garage door. Torsion springs apply torque to rotate the shaft, which has drums on each of the ends. Inside each drum is a cable that extends and is attached to a bolt or other fixture at the base of the garage door. The torsion spring then unwinds as the door is opened and winds as the door is closed. The standard torsion spring rating is 10,000 cycles, while the ideal torsion spring rating is 100,000 or more. The average torsion spring rating for most home garage door opener systems is 50,000 cycles.
