After prolonged use, the roller door may show signs of wear and tear even if you have maintained it well. If you are facing problems with the industrial roller door, do not waste time.
Take a few minutes out of your busy schedule and try to detect the issue with the door. Even very light grinding should be addressed because it could easily turn into a bigger problem at a later stage.
Check the tracks to make sure there is nothing to block the door. If you still experience problems after having checked the track, your door needs a safety inspection. The last thing you want is to let a small problem turn into a larger one, costing more money and risking the safety of those in the vicinity. Malfunctioning doors are a safety hazard.
