Roller doors and shutters provide a robust and secure barrier against intruders and destructive weather elements. They're made according to specifications, including great fit, smooth operation, and utmost security. More importantly, their low maintenance factor makes them an economic choice. Neverheless, these shutters and doors require regular checks to ensure they're in good working condition.
Checking for balance should be done each month by a skilled technician, preferably someone licensed and insured. The doors should be balanced, being smooth to roll up and down the roller tracks and able to stay stationary at any point along the tracks. Otherwise, the steel doors are out of balance and need to be adjusted.
Jammed and stiff doors should not be forcibly raised or lowered. Check individual parts such as springs and rollers for damage and have them repaired immediately. At times, all that is needed is some cleaning and removal of accumulated debris and dirt.
All moving components, save for roller tracks, should be lubricated each month. Lubricant facilitates smooth, safe and sufficient operation, but when placed in the tracks, it joins more grime and dirt that disruptions operation. Lubricant likewise increases the life of the moving parts, and the entire security shutter device. Among the important parts that need lubrication are bearings, hinges, rollers, and springs.
To prolong the life of the roller tracks and to encourage smooth and quite operation, occasionally apply silicon spray. The spray gives the tracks a slippery finish, enabling the doors slide properly. If you want to lubricate the tracks, use petroleum lubricant, but brush away dirt and grime before application and wipe away excess lubricant after.
Automatic doors and shutters should be set in manual mode annually or semi-annually. Manual operation should then be predetermined and done according to manufacturer instructions to prevent damage. The support brackets should be checked if they need servicing. If so, it's always advisable to contact a qualified technician right away.
Springs should be re-tensioned periodically, and each time the roller shutter gets abnormally heavy or difficult to lift or roll. Avoid operating doors with damaged tension springs because this causes damage to the motor and the opener.
Steel cables on the sides of the doors should be checked as well if they are in ideal shape and position or not. Replace protruding and broken cables right away to avoid accidents and worse damage to your doors.
All bolts and fixings should be tight in place. Loose ones can easily snap out of their holes and make the doors unstable and dangerous to operate. When there are loose bolts, do not operate the doors automatically rather, operate in manual mode in order to control the speed at which the roller doors are moving up or down.
