Torsion springs are a mainstay of overhead garage doors. Most homeowners have at least a passing knowledge of what they are and what they do. They know that the torsion spring sits above the door parallel to it and lifts and lowers the door by uncoiling and coiling respectively. They also know that torsion springs store massive amounts of energy when coiled and thus are extremely dangerous to work with and around. But what most homeowners aren’t aware of is that there are two main types of torsion springs, oil tempered and zinc galvanized, and that both have their advantages and disadvantages.
