Fire-Rated
Doors & Shutters
Need a fire-rated door or counter shutter for a fire separation, commercial kitchen, or opening in a fire wall? TyGrig installs and services fire-rated rolling steel doors and shutters across Chattanooga and the Tennessee Valley — and performs the annual drop testing code requires.
Code-Compliant,
Drop-Tested.
Fire-rated doors and counter shutters are rolling steel closures built to seal an opening in a fire-rated wall and close automatically when an alarm or a heat-activated link triggers them — slowing the spread of fire and smoke. TyGrig installs, services, and drop-tests fire-rated rolling doors and counter shutters across the Chattanooga, TN area for warehouses, kitchens, stairwells, and openings in fire separations.
Fire-rated rolling doors look much like standard rolling steel doors, but they’re listed assemblies with a fire rating and an automatic-closing mechanism. Counter shutters protect smaller openings like a commercial-kitchen pass-through or a service window. When fire codes call for a rated closure, the door, its guides, and its release have to be installed and maintained as a tested system — not pieced together.
We install new fire-rated assemblies, service and reset existing ones, and perform the annual drop test that NFPA 80 requires to confirm the door closes and latches under fire conditions — then document it for your inspector or insurer. Keeping these doors tested and ready is exactly the kind of thing a local team should handle. Call us and we’ll keep you compliant.

Yes. NFPA 80 requires fire-rated rolling doors to be drop-tested annually to confirm they close and latch properly under fire conditions. TyGrig performs the drop test, resets the door, and documents it for your inspector or insurer.
A fire-rated counter shutter protects a smaller opening like a commercial-kitchen pass-through or a cashier window, closing automatically in a fire just like a full fire door. We install and service both.
