A garage door spring balances the weight of a garage door and enables easy movement – opening and closing manually or automatically. It is made of high-tension steel, which has a limited lifespan and loses its effectiveness with time. Garage door springs have different quantity levels such as ‘10,000-use’ or ‘20,000-use’. Many buyers feel that this is quite a large number but when you evaluate and analyze, you will realize that a garage door is probably opened four to five times a day, every day, every year justifying the high quantity levels.
