A-60 Stainless Steel Sliding Fire Door for Marine Accommodation Spaces

Product Overview

The A-60 stainless steel sliding fire door is intended for openings in A-class divisions within ship accommodation blocks and superstructure spaces where horizontal sliding operation is required because a hinged leaf would obstruct a passageway, working area, or nearby equipment. The assembly consists of an insulated sliding door leaf, stainless steel exposed surfaces, frame, upper track and hanger arrangement, bottom guide, closing mechanism, sealing arrangement, and operating hardware. Left-opening and right-opening configurations can be supplied subject to the approved design and installation drawing.

The A-60 classification applies to the complete tested and approved door assembly, not only to the stainless steel surface. Door size, leaf and frame construction, insulation, track and roller arrangement, clearances, fixing method, closing or control system, and any optional fixed light, ventilator, or escape opening must remain within the approval scope. Manual, pneumatic, electric, or hydraulic operation can be discussed, but the selected configuration and emergency operating functions must be confirmed before quotation.

Quick Specifications

• Fire classification: A-60 → the complete door assembly is selected for an A-class boundary requiring 60-minute insulation performance within its approved configuration.
• Door arrangement: Single-leaf horizontal sliding → suitable where swing clearance is limited and side-running space is available beside the opening.
• Application position: Marine accommodation and superstructure internal boundaries → the exact location must match the vessel fire control plan and class-approved arrangement.
• Reference clear opening range: 800 × 1800 mm to 2000 × 2200 mm → covers personnel access and larger passage openings shown in the supplied dimensional table.
• Material concept: Stainless steel exposed surface with insulated steel-based door construction → exact stainless steel grade, leaf core, frame material, and finish are to be confirmed.
• Opening direction: Left-opening or right-opening → handing must be defined from an agreed viewing side and coordinated with the available track run.
• Operating options: Manual, pneumatic, electric, or hydraulic → availability depends on the approved door and control-system configuration.
• Optional performance: Gastight, watertight, weathertight, sound-reducing, fixed-light, ventilator, escape-opening, or anti-piracy features → each requires separate confirmation and must not be assumed from the A-60 rating alone.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm the required product as an A-60 single-leaf sliding fire door and identify the installation boundary on the vessel fire control plan, including flag and classification society requirements.

Step 2: Provide the clear opening, steel wall cut-out, bulkhead thickness, available wall length on the opening side and closing side, headroom for the track, sill or floor-guide condition, and the required left- or right-opening direction.

Step 3: Confirm the stainless steel requirement, including grade, surface finish, and whether stainless steel is required for the leaf skin, frame, trims, exposed hardware, or the complete visible assembly.

Step 4: Select manual, pneumatic, electric, or hydraulic operation and confirm local operation, remote release, fail-safe closing logic, emergency/manual operation, power supply, control voltage, and interface signals where applicable.

Step 5: State any additional requirement for gastightness, watertightness, weathertightness, acoustic performance, fixed light, ventilator, escape opening, removable sill, or anti-piracy locking. These features are separate from the A-60 rating and must be included in the approved configuration.

Step 6: Provide quantity, vessel type, newbuilding or replacement status, required certificate scope, delivery destination, required delivery time, and the existing door drawing or installation photos when available.

Structure

Insulated sliding door leaf | Stainless steel exposed skin / cladding | Steel or approved equivalent frame | Upper track and hanger rollers | Bottom guide | Closing and locking arrangement | Perimeter sealing arrangement | Manual or powered control system according to project

Fire Safety, Installation & Quality Advantages

• The complete leaf, frame, insulation, clearances, hardware, and fixing arrangement are coordinated as one fire-door assembly; changing any critical component may affect the approved A-60 performance.
• Horizontal sliding motion reduces the operational footprint in narrow accommodation corridors and service areas, but sufficient side-running space and track support must be reserved in the ship structure.
• Track straightness, hanger alignment, roller adjustment, and bottom-guide positioning are controlled to support smooth movement and reliable engagement with the closing and sealing arrangement.
• Insulation continuity around the leaf edges, frame, joints, and hardware penetrations is treated as a fire-boundary detail rather than a cosmetic lining detail.
• Stainless steel exposed surfaces provide a clean accommodation finish and can reduce routine coating maintenance; the exact grade, finish, and extent of stainless construction should be stated in the order.
• For powered versions, the actuator, controls, release logic, closing mechanism, guide rollers, and emergency functions should correspond to the tested or approved control-system arrangement.
• Installation dimensions are checked against the bulkhead opening, available track run, surrounding stiffeners, deck level, ceiling panels, and nearby piping or cable trays before production.

Custom Attributes

• Fire Rating: A-60 → applies to the complete tested and approved door assembly for installation in an A-class division.
• Standard Basis: SOLAS chapter II-2 and IMO 2010 FTP Code; CB/T 3234-2011 when specified → final compliance basis follows the vessel flag, class, and approval certificate.
• Door Motion: Horizontal sliding → requires side-running space, track support, and installation alignment.
• Leaf Type: Single leaf → double-leaf construction is a different approval configuration and should be ordered separately.
• Opening Direction: Left-opening / Right-opening → confirm the viewing side used to define handing.
• Material: Stainless steel exposed surface with insulated steel-based construction → stainless grade, frame material, core construction, and finish are to be confirmed.
• Operating Mode: Manual / Pneumatic / Electric / Hydraulic → select only a configuration covered by the required approval and project control philosophy.
• Additional Tightness: Gastight / Watertight / Weathertight available when specified → separate sealing design and test requirements apply.
• Optional Opening: Fixed light / Ventilator / Escape opening → permitted only when included within the tested or approved fire-door construction.
• Certificate Requirement: Type approval, MED conformity, class product certificate, or maker documents according to order scope → certificate availability must be confirmed before quotation.

How It Works

Door opens and travels along the upper track → Local command, remote release, or manual action initiates closing → Hanger rollers and bottom guide control the sliding path → The leaf engages the frame, seals, and locking arrangement → The closed assembly restores the fire boundary within its approved configuration → Emergency/manual operation remains available as specified

Applications

Passenger vessel accommodation corridors | Crew accommodation blocks | Ship superstructure internal boundaries | A-class passage and service-space boundaries where approved | Newbuilding projects | Replacement and retrofit projects subject to opening verification

FAQ

Q1: Does an A-60 fire rating also mean the door is gastight, watertight, or weathertight?

A1: No. A-60 is a fire-resistance classification for the complete door assembly. Gastightness, watertightness, and weathertightness are separate performance requirements with different sealing, structural, and test conditions. They must be specified and confirmed independently.

Q2: Can the clear size, stainless steel finish, window, ventilator, or operating system be customized?

A2: Customization is possible only within the limits of the applicable type approval or after approval review. The maximum tested door size, fire-exposure orientation, leaf and frame construction, insulation, hardware, track system, optional openings, and control system determine the permitted configuration.

Q3: What information is required for a reliable quotation?

A3: Provide the required fire class, clear opening, cut-out size, bulkhead thickness, available track run, opening direction, stainless steel grade and finish, operating mode, additional tightness or locking functions, vessel type, class requirement, quantity, destination, delivery time, and an installation drawing or existing-door photo.
