The Science of Garage Door Springs

Your garage door springs are the hardest-working — and most dangerous — components in your entire garage door system. Every time your door opens, these tightly wound coils of hardened steel release enough stored energy to lift 300+ pounds smoothly and safely. But when they fail, that same energy can cause serious injury in a fraction of a second.

We built this interactive guide to show you exactly what’s happening inside your torsion springs — the real physics, the real forces, and the real reasons why spring replacement is always a job for a trained professional.

Drag the simulator slider to feel the forces build, and scroll through each section to see why A Plus Garage Doors takes spring safety so seriously.
If your springs are showing signs of wear — or if you heard a loud bang from your garage — don’t touch anything. Call A Plus Garage Doors at (702) 297-7811, and we’ll handle it safely. We’re open 24 hours, 7 days a week.
