Galvanized Torsion Springs
Most springs designed for residential overhead doors are made from galvanized steel wire. The original steel wire is dipped in molten zinc. This is how it receives permanent coating which works to prevent rust and corrosion. Basically, the zinc seals the steel from the surrounding environment. The galvanized garage door springs tend to last longer. When it comes to performance, they are comparable to their counterparts. They unwind to transfer energy to the cables while the door is opening in order to facilitate the process. During closing, they get loaded with energy again through winding. These components require lubrication maintenance at least once a year and preferably every six months. It is essential for all coils to be well covered with the oil.
Malfunctioning Spring Repair
When any component of the spring system is not properly set or has been damaged or broken, this affects the operation of the entire door. If the door is hard to open and the opener is straining, this shows that there is too little tension in the spring and it has to be adjusted. If the door is cannot be opened at all, this is due to a broken spring. Quick visual inspection should confirm this. In this case, the old component needs to be removed and a new one of the same size should be installed in its place. If the door starts hanging on one side, this is usually due to snapped cable even when the door uses a pair of extension springs. The component has to be replaced as quickly as possible.
