Torsion springs
Back in the day, extension springs were commonly used as an integral component of garage doors. However, in today’s age, it is better to rely on torsion springs because of their exceptional mechanism. The torsion spring system has been designed in such a way that when door is lifted, the weight is transferred to its cables that are connected to the drums at both ends, tightly wound by spring over a shaft. As a result, the door has lesser cases of a broken spring and can hold the door more firmly.
