Fire-Rated Rolling Steel Doors
Protection That Works When the Heat is On.
In an industrial facility or automotive shop, fire safety isn’t just about a checklist, it’s about containment. A Fire-Rated Rolling Steel Door is your building’s last line of defense, designed to automatically close and seal off sections of your facility to stop the spread of smoke and flames.
At GDB Group, we specialize in the installation, testing, and emergency repair of UL-labeled fire doors. We ensure your facility meets NFPA 80 standards, protecting your assets, your employees, and your insurance standing.
Why Fire-Rated Doors Are Mission-Critical
-
Standard rolling doors fail in high-heat scenarios. Our fire-rated solutions are engineered for:
-
Automatic Activation: Integrated with your building’s fire alarm or heat-sensitive fusible links to drop the door the moment a threat is detected.
-
Structural Integrity: Built with heavy-duty galvanized steel slats that maintain their shape under extreme thermal stress.
-
Smoke Containment: Optional “SmokeSeal” technology to prevent the leading cause of fire-related injury from migrating through your bays.
-
NFPA 80 Compliance: Annual Drop Testing
Per National Fire Protection Association (NFPA) standards, fire doors must be inspected and drop-tested annually. GDB Group provides certified testing to ensure your doors are compliant and functional.
Our Inspection Process Includes:
-
-
Visual Inspection: Checking for dents, kinks, or track obstructions that could impede a drop.
-
Operational Drop Test: We trigger the release mechanism to verify the door closes at a controlled, safe speed.
-
Resetting & Recertification: We reset the tension and internal governors, providing you with the digital documentation required for Fire Marshal inspections.

Repair & Emergency Service
A fire door that won’t open kills your workflow. A fire door that won’t close kills your safety rating. We provide 24/7/365 repair for:
Fusible Link Replacement
Swapping out heat-triggered links that have aged or been damaged.
Governor & Release Mechanism Repair
Ensuring the “fail-safe” components haven’t seized over time.
Barrel & Spring Tension
High-tension repairs to ensure the door can be manually operated during power failures.
The GDB “No-Risk” Commitment
We don’t “guess” with fire safety. GDB Group technicians are trained on the specific mechanics of fire-rated closures from industry leaders like Cornell, Cookson, and Wayne Dalton. We provide the peace of mind that your facility is protected, and your paperwork is in order.
