The reason garage door openers do not burn out is because the springs allow the door to open easily by pulling the door up so the opener has less strain on the motor, the springs also help if you need to open the door manually. Usually two types of springs are used linear expansion and tensional springs. The springs on your garage door can pose a safety hazard. These kinds of springs are installed over a shaft that helps roll the door up to the open position. Garage door springs are very dangerous, even when the garage is closed, as they contain large amounts of potential energy (that’s just waiting to be suddenly converted to kinetic energy, ie movement) and have killed or seriously injured many people.
When building a home it is sometimes confusing when trying to figure out the opening of the garage door. The rough opening for a garage door, simply put, is the actual size of the door itself. You should make sure the garage door is properly balanced you can do this by slowly opening and closing the door, when the bottom of the door hits the floor evenly and the door doesn’t sway back and forth the door is balanced.
Some garage door openers offer heavier steel or a sturdier design. Some garage door openers do not use the steel chain pulley system; they use a screw threaded steel rod that turns to move the garage door up and down. If you are deciding on which type of garage door to purchase keep in mind the differences between wood and metal, the wood doors need to be taken care of just like a deck, you need to stain or paint it so it doesn’t rot, a steel door is easier to maintain. If you decide to get a steel door the main thing to check is that it has been properly prepared to prevent rust.
