Products Description
Fire rated steel doors play an essential role in protecting human life and minimizing property damage during fire emergencies. These labeled fire resistant doors effectively control the spread of fire and toxic smoke for durations up to 3 hours, providing crucial time for safe building evacuation and firefighting response. Commercial fire doors manufactured from steel offer an economical yet highly effective alternative to wooden fire doors when protection ratings exceeding 20 minutes are required.
Steel remains the only door material capable of delivering a full 3-hour fire-rating, making it the preferred choice for high-risk commercial buildings, industrial facilities, hospitals, schools, and multi-story residential complexes. The inherent strength and non-combustible properties of steel provide unmatched reliability in fire barrier applications.
* Heavy-duty 18-gauge steel construction for superior impact resistance
* Rigid honeycomb or high-density polystyrene insulating core
* Intumescent sealing systems that expand during fire exposure
* Pre-hung configurations available for faster installation
* Compatible with panic hardware, closers, and access control systems
The steel fire door design incorporates precision-engineered components that work together as a complete fire barrier system. The door leaf, frame, hardware, and sealing components are tested and listed as a complete assembly to ensure optimal performance during actual fire conditions. This integrated approach guarantees that every element functions properly when protection is needed most.
Our fire rated steel doors feature factory-welded construction with reinforced corners and edges to prevent warping and maintain dimensional stability throughout the product lifecycle. The galvanized steel substrate resists corrosion even in harsh environments, while the factory-applied primer provides an ideal surface for field painting to match any architectural color scheme.
