Key Features:
*A60 Fire Rating – Certified to withstand fire for 60 minutes, preventing flame passage and limiting heat transmission in accordance with IMO FTP Code Part 3.
*Double Leaf Configuration – Features two independently operating leaves, providing a wider passageway for equipment movement, stretcher access, or higher personnel traffic while maintaining full fire integrity.
*Heavy-Duty Steel Construction – Fabricated from high-strength steel with a ceramic or mineral fibre insulation core to ensure structural integrity under fire conditions.
*Self-Closing Mechanism – Both leaves are equipped with automatic closing devices to ensure the door closes securely in the event of fire or emergency, complying with SOLAS Chapter II-2 requirements.
*Corrosion-Resistant Finish – Protected with hot-dip galvanising, epoxy coating, or marine-grade paint for long-term durability in saltwater and humid marine environments.
*Approved Fire Seals – Integrated intumescent seals on both leaves and the meeting stile expand under heat to block smoke and flames, ensuring complete fire compartment integrity.
*Reliable Hardware – Heavy-duty stainless steel hinges, latches, and handles designed for frequent operation and emergency conditions. Typically includes flush bolts or a coordinating mechanism for proper leaf sequencing.
Typical Applications:
*Ship interior and exterior bulkheads requiring wider access.
*Offshore drilling rig accommodation and machinery spaces.
*Naval vessel main corridor and equipment room doors.
*Ferry and cruise ship fire zone boundaries.
*Marine industrial facilities with high-traffic or equipment passage needs.
Why Choose This Double Leaf Version?
While single leaf doors suit narrower openings, the double leaf configuration offers distinct advantages:
*Wider access – Accommodates equipment, stretchers, and higher personnel flow.
*Operational flexibility – Daily use of one leaf while keeping the second leaf secured; both open fully for large passages.
*Same A60 protection – No compromise on fire safety despite larger dimensions.
For ship designers and operators who require wide, safe access points on A60 bulkheads, this double leaf fireproof door delivers uncompromising performance.
