There are two main types of garage door springs: torsion springs and extension springs.
Torsion springs are installed above the door and are used to lift the weight of the door. They are wound tightly and use torque to provide the lifting force. They are typically more durable and longer-lasting than extension springs, but they require more professional installation and adjustment.
Extension springs are installed on either side of the door and stretch as the door opens and closes. They are less expensive than torsion springs, but they are also less durable and may need to be replaced more frequently.
Within each type of spring, there are also different sizes and strengths available to accommodate different door sizes and weights. It is important to choose the right size and strength of spring for your door to ensure that it functions properly and safely.
