Torsion springs are mounted on a torsion tube above your garage door horizontally and are wound up to create torque, or tension to raise and lower the door. There are three different types of torsion springs: oil tempered, galvanized, and powder coated.
Good: Oil tempered springs have the tendency to rust over time and can be noisy as the spring winds and unwinds.
Better: Galvanized springs don’t rust but can corrode which leads to squeaking as the spring ages.
Best: Powder coated springs will not rust or corrode because of the coating that protects them, leading to a longer lasting, quieter system.
