Automatic Garage Door Torsion Spring

__________________________________________

Spring Steel refers to a group of a low alloy, medium carbon steel or high carbon steel with excellent yield strength. Our CgoodSteel is the leading manufacturing and supplier of spring steel products. We use high grade of raw materials to ensure premium quality and high tensile.

A torsion spring has a stationary cone which secures the spring to the spring anchor bracket. Since this bracket is secured to the wall, the stationary cone, as its name suggests, does not move. The other end of the torsion spring has a winding cone. This winding cone is used when installing, adjusting, and uninstalling the springs. When installing the torsion spring, the coils of the spring are wound up to create a lot of torque.

Torsion springs are made of oil tempered spring wire. The spring wire is coated to improve corrosion resistance and fatigue resistance. Standard 10000 cycle and 25000 + high cycle springs are available in both left or right wound, precut with fittings installed. We have different models for you to choose from. In addition, we can also customize it according to your requirements

 

Garage door torsion springs from CgoodSteel

--Professional garage door, rolling shutter door hardware manufacturer in China for 18 years

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.

Torsion springs balance the garage door by applying torque to the shaft with drums at each end. Attached to each drum is a cable that extends to and is secured to the bottom fixture at the bottom of the door. The torsion spring unwinds and winds as the door is opened and closed to comprise a balanced system.

Torsion springs have three characteristics that determine the lift and cycle life. These properties are the wire size, inside diameter, and length. 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.
