GARAGE DOORS EXPERT

Garage door springs are an important component of any garage door system. They provide the necessary tension to lift and lower the door. There are two main types of springs used in garage doors: torsion springs and extension springs.

Torsion springs are the most common when it comes to garage door springs. They are mounted above the door and use a winding mechanism to provide tension.

Torsion springs are designed to last for many years, but they can eventually wear out and must be replaced. 

Extension springs are mounted on either side of the door and use a pulley system to provide tension. Extension springs are typically less expensive than the torsion springs but are also less durable and need to be replaced more often. Both springs are designed to provide the necessary tension to lift and lower the door, but they work differently.

Whether extension or torsion, the torque force required for a spring to operate correctly is founded in the law of gravity and how simply put, means that if your garage door is 100 pounds, then the springs need to exert an equal force for the springs to be counterbalanced to fit the weight of the door and calibrated to lift the same 100 pounds. 

**The amount of tension used is at its peak when the garage door is closed and is released when the door effortlessly glides up or slides sideways. Most garage door springs will then break when on the ground, but in the rare occurrence break while the door is raised, the potential for severe injury and damage is always a possibility. This is why people are correct when they avoid walking under a moving garage door. **

Understanding the science behind garage door springs can help you make an informed decision when it comes to choosing the right type of spring for your garage door system.
