Springs are a key element of a garage door mechanism – they balance the weight of the leaf and ensure the smooth, safe operation of the whole system. In practice, they are one of the most common points of failure, especially when incorrectly selected or of poor build quality.
For door manufacturers, integrators and service companies, what matters is not only the type of spring, but above all its technical parameters, durability and production repeatability.
Which springs are used in garage doors?
Torsion springs
The most commonly used solution is torsion springs, mounted on a shaft above the door. They balance the weight of the leaf by storing energy as they are twisted.
They are the standard in sectional and industrial doors thanks to their high durability and the ability to fine-tune their parameters precisely.
Extension springs
In simpler designs, extension springs are used, mounted on the sides of the door. They work in tension and are more often used in lightweight systems.
How to select a spring for a garage door?
Selecting a spring should be an engineering process, not one based on approximations. The key parameters include:
- the weight and dimensions of the door,
- the wire diameter,
- the spring diameter,
- the working length,
- the torque (for torsion springs),
- the number of operating cycles.
Incorrect selection leads to rapid wear, problems with door balance and an increased risk of failure.
The most common causes of spring failure
- too low a number of operating cycles,
- incorrect parameter selection,
- corrosion and lack of protection,
- assembly errors,
- poor material or manufacturing quality.
How to increase spring durability?
- select the spring for the real load,
- use appropriate materials,
- apply anti-corrosion coatings,
- carry out regular inspection and servicing,
- work with an experienced manufacturer.
