Description:
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. For example, if a garage door weighs 300KG, a spring force of 300KG needs to pull against the weight of the door. This can be accomplished with springs that either stretch or torque special parts to assist in balancing the door.
When torsion springs are wound, they grow in length. Since both ends of the torsion springs on steel rolling doors are secured and cannot move, the spring cannot grow in length. There are two options for fixing this problem. You can stretch the spring yourself with a come-a-long before you secure it to the shaft, or your can purchase pre-stretched springs. This allows the coils to be gapped and to lose most of this gapping when the door closes.
