Springs

Sectional doors are a popular choice for garages and industrial applications as they are space-saving and easy to operate. A crucial element in the functioning of sectional doors are torsion springs, which play a key role in supporting door operation.

Torsion springs for sectional doors

Torsion springs are specially designed spiral springs that are used to balance the weight of the sectional door and make it easier to open and close. Unlike other spring types, such as extension springs, torsion springs are mounted horizontally at the top of the door. This positioning allows the Springs to transmit torque evenly across the entire door. The main purpose of torsion springs is to balance the door; they are then referred to as spring balanced sectional doors. This means that the weight of the door is balanced by the Springs so that it can be opened and closed effortlessly. Correct balancing significantly reduces wear on the door moving parts and extends the service life of the entire system.

The right door spring as a replacement

Choosing the right torsion springs is crucial for the efficient and safe operation of a sectional door. Springs must be sized according to the weight and size of the door. Many manufacturers use a model marker to identify the correct spring, which allows easy identification of the correct replacement spring in the event of a replacement.

Torsion springs are indispensable components of sectional doors, ensuring their smooth operation, durability and safety.
