Oil Tempered Vs Zinc Galvanized Torsion Springs: What’s the Difference?

Torsion SpringsThe torsion springs that came with your garage door installation are going to wear out sooner or later. Two spring types are available: Oil tempered and zinc galvanized torsion springs. Most homeowners don’t give a second thought about the type of spring being used during a replacement. You should know, though, that you do have a choice.

Oil Tempered Torsion Spring

This is the more common of the two and has been around since the advent of the garage door. The spring is made from carbon steel that undergoes multiple heating and cooling phases using hot oil. This strengthens the spring so it can handle the constant stress applied when the garage door opens and closes. While durable, oil tempered springs are susceptible to rust. They can also leave traces of oil residue on the door and adjacent parts.

Zinc Galvanized Torsion Springs

Most technicians use oil tempered springs when switching out the springs. However, you can always enquire about zinc galvanized springs. This has zinced coated on the surface to protect the metal from rust. While this is definitely a plus, zinc galvanized spring as a whole is not more beneficial than oil tempered springs. The zinc itself actually weakens the metal and causes it to lose its tensile strength at a faster rate. We recommend that this spring be adjusted and tightened every six months by a garage door repairman.

Even with this drawback, some homeowners prefer zinc galvanized springs simply due to their shiny metal appearance. This does help improve interior appearances when the door is closed.
