The Classic Steel garage doors and Perth Garage Doors are durable with just occasional demand for cleaning or touch-up. Vinyl garage doors can last even longer, especially in environments with harsh weather conditions, and are more resistant to dents, are rustfree and not must be painted. Counterbalance springs are how your door is actually lifted and shut. It isn't the opener that actually lifts and closes your door. That just supplies the force to really get the door moving. It is actually the springs, which are wound tightly whenever your door is shut. As the doorway moves up, the springs unwind, which provide the force required to lift the doorway. As the door closes, the weight of the door actually winds the springs back up until it closes fully. At this stage the springs have their total tension again. These springs are normally exposed and when they're under full tension, can be hugely dangerous.
