If you are wondering what garage door torsion springs are, they are springs that you will find at the top of garage doors. They serve a very important function, and that is to help open garage doors.
Without garage door torsion springs, it would be difficult to open garage doors without exerting an enormous amount of force. A torsion spring works this way: Once the garage door closes, the cables at the bottom corners exert a force on the spring, thus creating static energy. When the door opens, this static energy is released, making the door spring open.
A very important of creating a garage door is using the correct spring. Often, you do not need to deal with this kind of math, unless if you were looking for a replacement. Actually, even if you were looking for a replacement, you should consult a garage door specialist, or at the very least, refer to videos made and uploaded by professionals.
How long does a torsion spring last? Well, that really depends on several factors, including the cycle of the spring. A 10,000 cycle torsion spring will last you seven years if the door opens and closes four times in a day. Springs with a higher cycle can last between 14 to 20 years.
Torsion springs for garage doors are easily bought online as there are many stores that offer them. However, you do need to be specific and provide the following information: length, wire size, inside diameter, spring wind, and type of ends. Again, if you don’t have this kind of information, you should consult with a garage door repairman. Even better, you should have him buy the spring for you instead.
How much do they cost? They cost anywhere from $150 to $250.
