The indices of a garage door torsion spring generally include five items: the length of the torsion spring, the inner diameter of the torsion spring, the diameter of the steel wire rope, surface treatment, and the service life of the sectional garage door torsion spring.

Indices of a Torsion Spring

- Length: The effective working length of the torsion spring determines its ability to deform and store energy.

- Diameter of spring: This includes the diameter of the steel wire of the torsion spring and the inner diameter. 

-Diameter of the steel wire rope: The diameter of the steel wire determines the strength and stiffness of the garage door torsion spring; the larger the diameter, the stronger the load-bearing capacity; the inner diameter of the torsion spring affects the space occupation and torque output of the torsion spring.

- Surface treatment: Surface treatment such as electroplating and spraying can improve the corrosion resistance and wear resistance of the torsion spring, thereby extending its service life.

- Service life: Considering the usage frequency of the garage door, the design of the torsion spring's cycle life is carried out to ensure that its performance remains stable after a certain number of opening and closing operations.

Data to Be Provided

These factors are determined by the following ones. That is to say, when we place an order for torsion springs, we need to provide the following data, and the engineers can design the torsion spring specifications you need based on this information:

1. The Length

The length should be determined according to the height and installation space. The higher the door body, the greater the torque required, and the larger the diameter of the spring.

2. The Weight of The Door Body

Including the weight of the door panel and the hinges, that is, the actual weight that the door needs to lift during operation. The heavier the weight of the door, the larger the diameter.

3. Surface Treatment 

Currently, our options include: black treatment, carbonization treatment, galvanizing treatment, and colored spraying treatment. This indicator is usually determined according to the customer's usage scenario and preferences.

4. The Service Life of The Torsion Spring

This value is determined based on the average daily usage frequency of the actual installed door. For example, in a household setting, it is 3-4 times a day, and 15,000 times in ten years is sufficient. In an industrial setting, it needs to ensure 36,500 times of usage per ten years.

Conclusion

Garage door torsion springs need to be custom-made based on the specific information of each door. So when you need a torsion spring for your garage door, please make sure to provide the data mentioned above. This will help us customize the best torsion spring for you.
