Tianjin Wangxia Garage Door Springs with 18000 cycles,  a "cycle" is one full opening and closing action. Garage door torsion springs are rated by cycle life. The average spring breaks about every 7 to 12 years with average usage for the recommended product. If a garage door has two or more springs and one breaks, all springs should be replaced to maintain proper balance. It is very common if only the broken spring is replaced the other will typically break within a short time period.

Q8. What do colors mean on garage door torsion springs?

The color code on a torsion spring indicates whether it is a “right wind” or “left wind” spring, with black indicating right wind and red indicating left wind. Beyond that the torsion spring is color coded so that technicians can determine the thickness, or gauge, of the wire.

Q9. How to Work Out What Size Garage Door Springs You Require?

The springs are the unsung heroes of your overhead garage door. They do the heavy lifting while the “opener” essentially acts as a regulator - getting the door started and then making sure the upward or downward motion is nice and smooth. Garage door springs are incredibly rugged and durable but even the toughest will wear out and need to be replaced after years of regular use.
