What You Need To Know About Commercial Door Torsion Springs

Torsion springs are a vital component of overhead commercial doors. However, torsion springs are subject to wear and tear over time and may need to be replaced to prevent a catastrophic failure. Understanding how torsion springs work and the common causes of damage can help ensure your overhead doors continue to work efficiently and safely for years to come.

What Are Torsion Springs and How Do They Work?

Garage or overhead commercial door torsion springs are tightly wound metal springs located above the door opening, parallel to the door itself. Torsion springs store mechanical energy when they’re twisted or wound up.

When a garage door is closed, the torsion springs are under tension, storing energy. As the door opens, the stored energy is released, assisting in lifting the door. This counterbalance system helps offset the door's weight, making it easier to open manually or for the door operator to lift it.

Torsion springs require proper balance and tension for overhead doors to operate safely and smoothly. If the springs suddenly break, the entire door can come crashing down, damaging property and injuring people. That’s why it’s important to have your door’s torsion springs installed, adjusted, and maintained by trained professionals to ensure they function correctly and to prevent accidents or damage caused by improperly adjusted or worn-out springs.

4 Common Causes of Torsion Spring Damage

Here are some of the common ways commercial door operation can damage the torsion springs:

  1. 1. Normal wear and tear. A standard torsion spring is rated at about 10,000 cycles, so busy commercial operations often see their torsion springs wear out after only a few years. Therefore, it’s crucial to regularly monitor the springs for any signs of excessive wear or damage that may require professional attention.
  2. Rust and corrosion. Exposure to moisture, harsh weather conditions, and corrosive elements like humidity and salinity can lead to rust and corrosion on commercial door torsion springs. Rust weakens the structural integrity of the springs, making them more prone to failure.
  3. Incorrect spring size or type. Using incorrect spring sizes or types for commercial doors can place undue stress on the torsion springs. Springs that are too weak may not adequately support the weight of the door, while springs that are too strong can cause excessive tension. This mismatch can lead to rapid wear, failure, and potential safety hazards.
  4. Improper maintenance. Inadequate or improper maintenance can contribute to premature wear and tear of torsion springs. Failing to lubricate the springs regularly, neglecting to check for loose or damaged components, or ignoring signs of overhead door wear can accelerate the springs’ deterioration. A planned pre-scheduled maintenance program can help catch potential issues early and extend the lifespan of the springs.

3 Signs Your Torsion Springs Need Repair or Replacement

Being able to recognize when torsion springs need repair or replacement is essential. Keep an eye out for these warning signs:

  1. Visible wear and tear. Inspect the torsion springs for any visible signs of damage, such as fraying cables, gaps in the coils, or distorted shapes. These are all signs that the springs need to be repaired or replaced.
  2. Difficulty in opening or closing. If the commercial door has trouble opening or closing smoothly, it may be due to worn or damaged torsion springs. If the door is unbalanced or jerks or stalls during operation, schedule a professional evaluation to determine if the springs are the cause.
  3. Loud noises. Unusual noises during the operation of the commercial door, such as squeaking, grinding, or popping sounds, may indicate worn or damaged torsion springs. Don’t ignore these noises. Get immediate attention from a trained professional.

Danger! Why You Need a Professional Technician

Repairing or replacing commercial door torsion springs should never be a DIY project. These springs are under high tension and can cause serious injury or property damage if mishandled. Professionals have the training and specialized tools required to safely work with torsion springs. They understand the intricacies of proper installation, tension adjustment, and safety protocols, minimizing the risk of accidents during the repair or replacement process.
