Rolling steel doors do work that sectional doors cannot: they coil into a small headroom, they take abuse, and in a fire-rated opening they are a life safety device that happens to look like a door.
We service counter shutters, rolling service doors, security grilles, and fire-rated rolling doors and shutters, including the testing and documentation that the rated ones require every year.
Curtain and slats. Damaged slat replacement, endlock and windlock wear, curtain realignment after impact.
Barrel and counterbalance. Spring tension, bearings, and the adjustment that decides whether the door runs or drags.
Guides and bottom bar. Guide wear and alignment, astragal and sensing edge, locking and interlocks.
Operators. Chain hoist, crank and motor operation, limits, and safety device function on every powered door.
Counter shutters in food service, retail and reception positions get their own attention: they are usually in a public area, they get operated by staff rather than trades, and a door that has to be forced is a door that will be broken shortly.
A fire-rated rolling door has a release mechanism designed to let the curtain close under gravity when the fire alarm or a fusible link activates. The rest of the year it never does this, which is exactly why it has to be tested.
NFPA 80 requires an annual drop test on every fire-rated rolling door and shutter, performed and documented, with the door reset and returned to normal operation afterward. Deficiencies have to be corrected without delay, and the record has to exist when an inspector asks for it.
We carry out drop testing and resetting, correct what the test finds, and issue documentation in the same format as the rest of your fire door records. If you already use us for fire door inspection, your rolling shutters belong on the same cycle rather than on a separate one nobody owns.
Fire shutters are the most commonly overlooked rated assembly in a building. They sit above a counter or inside a soffit, they are often painted over, and because they are not swing doors they fall outside whoever is tracking fire doors.
When we survey a portfolio we document them whether or not they were on the list, because an untested fire shutter is a finding waiting to happen and it is cheaper to find it ourselves.
