Key Features:
*B-15 Fire Rating – Both the door and the surrounding partition panel are certified to prevent flame passage for 15 minutes and limit temperature rise on the unexposed side in accordance with IMO FTP Code Part 3.
*Integrated Door + Partition Panel – A complete factory‑assembled unit comprising a single leaf fireproof door pre‑hung within a lightweight, non‑combustible partition panel. Eliminates on‑site fitting, reduces installation errors, and guarantees fire‑rated continuity between door and bulkhead.
*Single Leaf Configuration – Compact and space‑efficient, ideally suited for standard cabin entrances, corridor openings, and stateroom access points.
*Lightweight Construction – The partition panel is fabricated from thin‑gauge steel facings with a non‑combustible mineral fibre or composite core. The door features similar lightweight construction, reducing overall weight without compromising fire integrity.
*Self‑Closing Mechanism – Equipped with an automatic closing device to ensure the door closes securely in the event of fire or emergency, complying with SOLAS Chapter II‑2 requirements.
*Pre‑Drilled & Pre‑Finished – Ready for immediate installation with pre‑drilled mounting points for adjacent bulkhead connections. Finished with marine‑grade paint, PVC laminate, or decorative veneer options to match interior cabin aesthetics.
*Factory Fire Testing – The complete door‑on‑panel assembly is fire tested as a single unit, eliminating the risk of field installation compromises that could void fire certification.
*Reliable Hardware – Stainless steel hinges, latch, and handle pre‑installed and adjusted at the factory for consistent operation.
Typical Applications:
*Modular cabin construction for cruise ships and passenger ferries.
*Crew quarters on cargo vessels and tankers.
*Offshore accommodation modules and living quarters.
*Naval vessel staterooms and officer cabins.
*Marine hotel areas and passenger staterooms.
*Prefabricated marine interior systems.
Why Choose the Door‑On‑Partition Panel Version?
Traditional marine fire doors are supplied as standalone units, requiring shipyards to cut bulkhead openings and field‑fit the door, which introduces installation variability and potential fire integrity risks. The B‑15 Class Single Leaf Fireproof Door (On Partition Panel) offers significant advantages:
*Simplified installation – One complete unit, ready to mount.
*Guaranteed fire continuity – Factory‑tested door‑to‑panel interface.
*Reduced shipyard labor – No on‑site cutting, fitting, or alignment adjustments.
*Consistent quality – Factory‑controlled assembly and finishing.
*Faster cabin completion – Accelerates modular construction timelines.
For shipyards, marine outfitters, and modular cabin manufacturers seeking efficiency without compromising fire safety, this integrated door‑on‑partition‑panel solution delivers uncompromising performance.
