Garage Door Spring Types

Garage door springs are crucial to the flawless operation of your garage door system. They are designed to offset the substantial weight of the door, allowing it to open and close with ease. Mismanagement of the vast tension they carry can pose a risk, hence the installation or replacement is generally advised to be performed by a professional. There are two primary spring types – torsion and extension, and comprehending their functioning is vital for prolonging the lifespan and security of your garage door.

This post will explore the essential realm of garage door spring types, highlighting their significance, varieties, and upkeep.


Torsion Springs

Torsion metal coils play a critical role in the functioning of a garage door. They utilize torque to lift the garage door off the ground and counterbalance its weight. These springs, located above the door opening, turn and coil on a shaft whenever the door is opened or closed, ensuring a smooth and balanced operation.

A torsion spring system operates through a principle of twist mechanics. These springs store mechanical energy when they are twisted – the greater the twist, the more energy is stored. When the spring is released, it exerts a force and rotates in the opposite direction, performing necessary work. Standard torsion springs are widely used in many different products such as clothespins, garage doors, and even watches.

Torsion metal coils have a variety of designs to suit different applications. Types include spiral torsion, coil torsion, and double torsion. Each type has specific characteristics that make it suitable for certain applications, such as garage doors, clothespins, or clipboards.

Extension Springs

Extension springs are an essential component in the mechanism of a garage door system. They function by expanding one spring and contracting the other one to counterbalance the weight of the garage door as it lifts and lowers. These springs are linked to the door’s bottom corners through pulley cables, allowing the springs to stretch when the garage door closes and to revert to their original length when the door opens. This act of extending and retracting provides the force necessary to lift and lower the heavy garage door with ease.

Most typical residential garage doors use extension springs due to their affordability and straightforward installation process. They are often sold in pairs since garage doors require two springs for balanced operation. Importantly, extension springs are offered in different sizes and weights, designed to match a variety of garage door sizes and weights, making them a versatile choice for homeowners.

However, extension springs have a limited lifespan mostly due to metal fatigue caused by countless expansion and contraction cycles. When excessively worn or damaged, they can pose significant safety risks as they can snap and cause severe injuries or property damage. Therefore, regular maintenance and inspections are critical to ensure the longevity and safe operation of extension springs.

Despite these pitfalls, extension springs play a vital role in the functionality and convenience of automatic garage doors. Their relatively low cost and easy installation process make them an immensely popular option for homeowners. Nevertheless, their performance and safety rely heavily on proper installation, regular upkeep, and timely replacement, providing a reliable and efficient solution for garage door systems.

Overall, the extension spring of a garage door is a vital component in making modern garage doors user-friendly and practical.

How To Choose The Right Garage Door Spring Type?

Choosing the right type of spring is a crucial aspect not only for the proper functioning of the garage door but also for the safety of those who use it. The spring system is responsible for counterbalancing the weight of the door, allowing it to open and close smoothly.

What Are The Signs Of A Broken Spring Of Your Garage Door?

 A garage door’s functionality and safety significantly rely upon its spring mechanism. Therefore, a broken spring in the garage door can cause hindrance to its regular operation and can even pose a safety risk. One of the most apparent signs of a broken garage door spring is when the door doesn’t open or close properly. The rolling door might go up or down in a lopsided manner as it may not be aligned with the horizontal track, or it might be entirely stuck.

Another tell-tale sign is a loud, almost explosive noise when the spring breaks. As the springs are under high tension, their breakage can produce a sound akin to a firecracker. One may also notice the separation of the spring into two pieces, visible to the naked eye. You might experience difficulty in manually lifting the garage door, revealing the fact that the springs are no longer capable of carrying the door’s weight. There can also be visible gaps in the torsion spring or the extension spring might appear to be elongated.

Furthermore, if the garage door falls too quickly when you’re trying to lower it, it’s a telltale sign of a broken spring. Always reach out to professionals when you notice such symptoms, as handling broken springs can be risky without proper training and equipment.

Can You Replace The Spring On Your Garage Door By Yourself?

While it is technically feasible to change the spring on your garage door yourself, this task is generally not recommended for DIY due to the inherent dangers and complexities involved. Door springs are under a significant amount of tension and if improperly handled, they can cause serious personal injuries or even life-threatening situations.

Additionally, the garage door itself weighs significantly and mishandling could lead to substantial property damage. This task requires specific tools and a degree of experience and understanding of the mechanism involved. Misadjustment can also lead to the garage door opener operating incorrectly as it may not be aligned to the horizontal track or breaking down sooner.

Therefore, professionally skilled technicians often carry out this task with appropriate safety measures and the right tools. Many garage door repair companies offer affordable services for such needs. It is imperative to understand the potential risk factors of such seemingly simple tasks and considering professional assistance for safety and better results.


Final Thoughts

To sum up, the different types of garage door springs, such as torsion and extension springs, play a fundamental role in the operation of a garage door. They bear the weight of the door and enable smooth opening and closing. However, they often succumb to wear and tear after prolonged use. When they break, it is vital to undertake a safe and effective replacement process.

Homeowners can either choose DIY replacement or professional services. However, due to the risks involved and the complex nature of the task, hiring a professional is advisable. They have the necessary skills and tools to perform the task efficiently and safely, thereby ensuring the longevity and optimal performance of your garage door.
