Knowing Commercial Garage Door Prices in Buffalo is Half the Battle
There are three basic types of electronic garage doors: chain drive, screw drive and belt drive. Most electronic systems have ceiling-mounted electric motors as their cores, linked to the doors they’re operating through a mechanism responsible for opening or closing doors. Another type, the torsion system, does not need a chain, belt, or screw; unlike other designs, a torsion-operated garage door does not require overhead tracks and a ceiling-mounted box. Some systems can be added to existing doors; thus, it’s often not necessary to replace the old one. However, there may still be a need to modify the opening mechanism of the existing door so that it can accommodate an electric opener.
