The Classic Steel garage doors and Perth Garage Doors are durable with just occasional demand for cleaning or touch-up. Vinyl garage doors can continue even longer, especially in environments with harsh weather conditions, and are more immune to dents, are rustfree and not have to be painted. Counterbalance springs are how your door is actually lifted and closed. It is not the opener that actually lifts and shuts your door. That just supplies the drive to get the door going. It is actually the springs, which are wound tightly whenever your door is shut. As the door 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 completely. At this point the springs have their full tension again. These springs are usually exposed and when they are under full tension, can be particularly dangerous.
