    Applications:


    Garage door torsion springs have three characteristics that determine the lift and cycle life. These properties are the wire size, inside diameter and number of coils. The lift, which is determined by the torque of the spring, tells how much door weight the spring can lift. The cycle life tells how many times the garage door should open and close before the spring breaks.


    Garage door torsion springs are secured to a metal shaft above the garage door. Depending on the system, the shaft may pass through the middle of the springs or spring, or the shaft may sometimes house the spring. If the shaft passes through the middle of the torsion spring, the spring may be mounted in the middle of the shaft or on the end of the shaft by the outside edge of the garage door.


    How to order your garage door springs

    For a quotation, we need info of your torsion spring as follow:

    1. Inside diameter
    2. Wire size
    3. Length
    4. Type of spring ends
    5. Gapped or ungapped

    And before production, we will make a drawing to let you confirm.
