A60 Class Single Leaf Fireproof Door

A60 Class Single Leaf Fireproof Door

Product Introduction:

The A60 Class Single Leaf Fireproof Door is a high-performance, marine-rated fire protection system engineered for use on ships, offshore platforms, floating production storage and offloading (FPSO) units, and other maritime vessels. Designed to meet the stringent requirements of the International Convention for the Safety of Life at Sea (SOLAS) and the International Maritime Organization (IMO), this door provides up to 60 minutes of fire and smoke containment, making it a critical safety component for bulkhead installations, escape routes, and compartment separation in hazardous marine environments.

Constructed from heavy-gauge steel with a non-combustible insulation core—typically composed of high-density ceramic fiber or rock wool—the A60 Class Single Leaf Fireproof Door delivers exceptional thermal resistance and structural integrity under extreme conditions. During a fire, the insulation core limits temperature rise on the non-fire side, while intumescent seals expand to block the passage of smoke and hot gases. The door is also designed to withstand the constant vibration, saltwater corrosion, and humidity typical of marine operations, ensuring long-term reliability.

The single leaf configuration features a self-closing hinge mechanism that automatically returns the door to a closed position after each use, a mandatory requirement for fire-rated marine doors. A heavy-duty compression locking system secures the door tightly against the steel frame, and an optional marine-rated porthole (with fire-resistant glass) allows visual inspection without compromising safety. For additional protection, the door can be specified as weathertight or watertight to prevent ingress of rain, spray, or seawater. All exposed surfaces are treated with marine-grade anti-corrosion primer and can be finished with epoxy or polyurethane paint for enhanced durability.
