Commercial / Industrial Overhead Garage Door Torsion Springs Alloy Steel Material

Specifications:

Description:      

The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.

Commercial and industrial torsion springs are used in warehouses, loading docks, and a variety of other locations that require large overhead doors. Because of the wide range of applications, door sizes and therefore door weights, the torsion springs on commercial and industrial doors vary greatly in size and lift.

Regardless of your spring dimensions, lift system, shaft style, spring system, or number of springs, you can order replacement torsion springs for your commercial or industrial garage door from us.

Applications:

Garage door springs counterbalance the weight of the door to make it easy to open and close. They serve the same purpose of counter weights used to balance doors in centuries past and in many doors today.
