Understanding the Importance of Garage Door Springs in Commercial Doors

garage door spring

The garage door spring is one of the most vital components of your commercial garage door. This unassuming metal piece carries the heavy responsibility of managing the door's weight, enabling ease in its opening and closing.

In a commercial setting, the function of a garage door spring is amplified due to the larger size and heavier weight of garage doors compared to residential ones. A well-maintained spring can contribute to a longer garage door lifespan, smoother operation, better safety, and fewer repair issues.

Different Types of Garage Door Springs

A. Torsion Springs

Torsion springs are commonly used for more extensive and heavier garage doors due to their durability and strength. Torsion springs operate on the principle of torque or twisting motion. When the garage door descends, the springs wind up and store mechanical energy. This energy is released when the door is lifted, helping in the door's smooth upward motion.


  • Longer lifespan: Torsion springs can withstand more wear and tear than their counterparts and last many years with proper care.
  • Better balance: These springs offer better weight distribution, leading to smoother, more straightforward garage door operation.


  • Higher cost: Due to their greater lifespan and efficiency, torsion springs tend to be more expensive.

Torsion springs are best suited for commercial and industrial settings where garage doors are more significant, heavier, and face more frequent use. They're ideally used in situations demanding longevity, smooth operation, and durability.

B. Extension Springs

Extension springs operate differently from torsion springs. Extension springs use the principle of extension and contraction. They extend when the garage door is lowered and contract when it is raised. This contraction helps lift the door more quickly.


  • Cost-effective: Extension springs are generally more affordable than torsion springs.
  • Easy replacement: These springs can be more easily replaced than torsion springs.


  • Lower lifespan: Extension springs don't last as long as torsion springs and require frequent replacements.
  • Uneven lifting: These springs can sometimes result in uneven garage door lifting.

Extension springs are ideal for smaller commercial garage doors where operational efficiency and cost-effectiveness are essential.

How Garage Door Springs Work

Garage door springs play a crucial role in a door's operation by balancing weight, making it easier to open and close.

The Role of Springs in Garage Door Operation

Whether a torsion or extension spring is used, both serve to counterbalance the weight of a door. In simple terms, they act as a counterforce to the door's weight. When the garage door is lowered, the springs store energy. When the door is lifted, this stored energy helps ease the lifting process, making the heavy door seem remarkably light.

A poorly balanced door exerts undue stress on the garage door opener and other components, leading to more frequent garage door repairs.

Safety Measures

Importance of Safety in Spring Operation

Commercial garage door springs are under tremendous tension and, if mishandled, can cause severe injury or damage. Safe operation of the door springs is crucial to protect individuals and prevent premature wear and tear on the garage door system as a whole. Appropriate training and the right tools are necessary when working with these springs.

Risks of a Faulty or Broken Garage Door Spring

A faulty or broken garage door spring can present several risks. A broken spring can cause the door to descend rapidly, potentially causing injury or damage to property. Additionally, due to the heavy work done by springs in lifting your garage door, a faulty or broken spring can cause unnecessary strain on your garage door opener, leading to premature failure of the system.

Factors to Consider When Choosing a Garage Door Spring

Door Weight

The weight of the garage door directly affects the type of spring required. Heavier doors need springs with a high tensile strength.

Door Height

Just like the weight, the height of your door also affects the choice of your spring. Taller doors require longer springs that provide better lift.

Door Width

Wider doors may require two springs to handle their wider dimensions effectively.

Life Cycles

A cycle is defined as a garage door going up and down once. The expected number of cycles a spring can handle without breaking is crucial in determining its longevity and suitability for your commercial needs.

Professional Recommendations

To ensure optimal operation and safety, consider having a professional garage door supplier determine the correct spring for your commercial garage door based on these and other factors such as usage frequency and yearly maintenance plans.

Garage Door Spring Maintenance and Safety

Routine maintenance for garage door springs is a necessary precaution to prevent unexpected breakdowns and extend the door system's life.

Regular Inspections

Regular visual and manual inspections by trained professionals can help detect any signs of wear or damage earlier and prevent sudden spring failure.


Proper lubrication keeps the springs operating smoothly, reduces friction-induced damage and can increase the life cycle of your garage door springs.

Adjustment and Replacement

Spring's tension may need to be adjusted periodically. Over time, springs will need to be replaced. Hiring a professional from our commercial garage door repair section ensures accurate adjustment and safe, adequate replacement that aligns with your specific door specifications.

Remember that while the information provided aims to be comprehensive, it does not substitute professional advice. Accurately measuring and installing garage door springs is a dangerous task only trained professionals should perform.

Signs of a Failing or Broken Garage Door Spring

  1. Unusual noises

    One of the most apparent signs of a failing garage door spring is unusual noises. When operating the garage door, you might hear loud, irregular popping or snapping. These sounds typically indicate that the metal coils within the spring are under significant strain and reaching their limit.

  2. Difficulty in opening or closing the door

    Another typical indication of a failing spring is if you're facing difficulty while opening or closing the door. This stems from the spring system offsets the door’s weight. When the springs are worn or damaged, they can't perform their function efficiently, making the door more complicated to operate.

  3. Visible wear and tear on the springs

    Regular inspection of your commercial garage door springs can assist in identifying visible wear and tear. Signs to look out for include rust, spring gaps, and a stretched-out appearance, suggesting the springs have weakened over time.

If you notice any of the signs above, immediate action is recommended. Potential solutions include tightening loose parts, applying lubrication to minimize noise, or replacing the springs entirely. However, given the complexity of this task, it's advisable to seek help from our experienced commercial garage door repair experts for proper guidance and service.
