A-60 Class Weathertight Double Leaf Fireproof Door
Product Introduction:
The A-60 Class Weathertight Double Leaf Fireproof Door is a high-performance marine-rated door system designed for demanding offshore and shipboard environments. Engineered to meet stringent SOLAS (Safety of Life at Sea) and IMO (International Maritime Organization) requirements, this door combines A-60 fire resistance, weathertight sealing, and the operational convenience of a double leaf configuration—making it the ideal solution for larger access points on vessel exteriors, deckhouses, and offshore installations.

Key Features:
*A-60 Fire Rating – Certified to withstand fire for 60 minutes, preventing the passage of flames and limiting heat transmission in accordance with IMO FTP Code Part 3.
*Weathertight Performance – Provides effective sealing against water ingress, wind, and sea spray, suitable for exposed exterior locations subject to harsh marine conditions.
*Double Leaf Configuration – Features two independently operating leaves, allowing for wider passageways while maintaining full fire and weather integrity. A standard active leaf and a passive (or alternately active) leaf facilitate both daily personnel movement and emergency access.
*Heavy-Duty Steel Construction – Fabricated from high-strength steel with a robust core of ceramic or mineral fibre insulation to ensure structural integrity under fire and mechanical stress.
*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 requirements.
*Corrosion-Resistant Finish – Protected with hot-dip galvanising, epoxy coating, or marine-grade paint systems to withstand saltwater, humidity, and UV exposure over extended service life.
*Approved Sealing System – Integrated intumescent seals (expand under heat) and weathertight rubber gaskets provide dual protection for fire integrity and water/air tightness.
*Quick-Acting Latches & Hinges – Heavy-duty stainless steel hardware designed for reliable operation under heavy use and emergency conditions.
Typical Applications:
*Ship exterior bulkheads on main decks and superstructures.
*Offshore drilling rigs and accommodation modules.
*Ferry and cruise ship weather decks.
*Naval vessel external access points.
*Offshore wind substations and platform control rooms.
*Marine industrial facilities requiring wide, fire-rated weathertight openings.
Why Choose This Double Leaf Version?
While single leaf doors suit smaller openings, the double leaf configuration offers distinct advantages:
*Wider access – Accommodates equipment movement, stretchers, or higher personnel traffic.
*Operational flexibility – Daily use of one leaf while keeping the second leaf secured; both open fully for large passages.
*Same A-60 protection – No compromise on fire safety or weather integrity despite larger dimensions.
For ship designers and operators who require wide, safe, and weathertight access points on exposed decks, this double leaf A-60 door delivers uncompromising performance.
