They say you should examine your garage door frequently to make sure it's being maintained properly. But how are you supposed to know what you're looking at? This article will tell you what the different parts of the garage door is made of, so you know what you're looking at, and whether any individual components need replacing or repairing.
There are several rectangle panels and components that comprise a generic garage door. Garage door panels come in a variety of colors and styles and can support windows and decorative fixtures made of wood, steel, aluminium, fibreglass, or vinyl. For many garage door designs, when broken, independent panels can be replaced and repaired, rather than replacing the whole garage door.
The panels are secured to one another by large leaf hinges. To enable the garage door to bend as it moves along the track, they fold into themselves. They're very durable, but they need to be regularly lubricated so that they don't make a noise. You can resolve this by buying and regularly applying garage door lubricant, which you’ll be able to pick up at your local DIY store.
Located on either side of the garage door and above the door, when opening or closing, the door's tracks guide the garage door in and out of position. Garage door tracks should not be lubricated, but it's also a good idea to wipe them down with soap and warm water on a regular basis so your garage door can slide easily.
A set of rollers are on each side of the garage door, which slide up and down the tracks as the garage door opens and closes. A metal rod and a wheel made of nylon, steel, or plastic are made for each roller. Rollers wear over time, so they need to be regularly replaced. If your rollers need to be replaced, call a garage door technician in to assess the situation. Rollers may need lubrication too, so make sure you do this on a regular basis to avoid the garage door jumping it’s tracks or making any unpleasant noises.
The torsion spring is situated immediately above the door of the garage. Its purpose is to counterbalance the door's weight. It's under intense stress, so a non-professional can never try to interfere with it. If you suspect your torsion spring isn't working correctly due to your garage door becoming imbalanced or not working correctly, consult a garage door technician.
Instead of a torsion spring, some garage door systems, especially older ones, have a pair of extension springs. They either stretch sideways alongside the overhead tracks on either side of your garage door or directly above your head. They have the same purpose as the torsion spring, but are less stable, because if a spring fails, the pieces may become dangerous and break off, putting you at risk of harm when opening your garage door. Extension springs should always be fitted with safety cables to decrease this risk.
