Different Types of Springs and Their Benefits for Garage Door Systems



Garage doors are an essential part of our homes, providing security, convenience, and protection for our vehicles and belongings. Behind the scenes, one crucial component that allows garage doors to function smoothly is the type of springs used in their mechanisms. Springs play a pivotal role in the opening and closing of garage doors, and understanding the different types of springs and their benefits is crucial for homeowners. In this blog, we'll delve into four types of garage door springs: Torsion Springs, Extension Springs, Oil-Tempered Springs, and Galvanized Springs.




Torsion Springs


Torsion springs are one of the most common types of springs used in modern garage door systems. They are mounted horizontally above the door's opening and work by twisting or winding to store energy. When the door is activated, these springs unwind to lift the door and rewind when closing it. Here are some benefits of torsion springs:


  • Durability: Torsion springs have a longer lifespan compared to extension springs, making them a cost-effective choice in the long run.

  • Smooth and balanced operation: Torsion springs provide even and controlled lifting, resulting in a smoother door movement.

  • Space-saving design: Torsion springs require less space compared to extension springs, making them ideal for smaller garages with limited headroom.



Extension Springs


Extension springs are typically found on older garage door systems and are mounted on either side of the door. They extend and contract to provide the necessary force to open and close the door. While they are less common in modern setups, they still have their advantages:


  • Cost-effective: Extension springs are often more budget-friendly than torsion springs, making them a suitable choice for homeowners on a tight budget.

  • Easy maintenance: They are relatively easy to replace and maintain, ensuring your door functions well with minimal effort.



Oil-Tempered Springs


Oil-tempered springs are a subtype of torsion springs. What sets them apart is the manufacturing process, in which they are heated and quenched in oil, making them more resilient and durable. Here are their benefits:


  • Enhanced durability: Oil-tempered springs have a longer lifespan and can withstand extreme temperature variations, making them ideal for various climate conditions.

  • Reduced risk of rust and corrosion: The oil tempering process provides a protective layer that prevents rust and corrosion, extending the spring's life.



Galvanized Springs


Galvanized springs are another type of torsion spring, but they have a protective layer of zinc applied to the surface. This layer of zinc helps resist corrosion and adds an extra layer of durability. Here's why galvanized springs are beneficial:


  • Corrosion resistance: The zinc coating prevents rust, making galvanized springs ideal for coastal or humid environments.

  • Long-lasting finish: The galvanized coating extends the spring's lifespan, reducing the need for frequent replacements.



Choosing the right type of spring for your garage door is crucial for its functionality, longevity, and your peace of mind. Whether you opt for torsion springs, extension springs, oil-tempered springs, or galvanized springs, understanding their benefits can help you make an informed decision. If you're unsure which spring type is best for your garage door system, consider consulting a professional garage door technician at Rockford Door Company who can assess your specific needs and recommend the most suitable option. Your garage door springs play a vital role in your daily life, so investing in the right type can make a significant difference in your overall garage door experience.
