Available Configurations
Fire-Rated Doors
- B-15 Class Doors — Designed for installation in B-class divisions requiring a certified fire-resistance performance of 15 minutes.
- A-0 Class Doors — Intended for A-class divisions where structural fire integrity is required without a specified insulation period.
- A-30 Class Doors — Designed for A-class divisions requiring fire insulation performance for up to 30 minutes, subject to the approved project configuration.
- A-60 Class Doors — Designed for high-protection areas requiring fire integrity and insulation performance for up to 60 minutes.
Tightness Configurations
- Weathertight Doors — Designed to limit the ingress of rain, spray and external water under normal marine operating conditions.
- Watertight Doors — Engineered for compartments and access points requiring controlled resistance to water penetration. The required pressure and leakage performance are established according to the vessel specification and applicable classification requirements.
- Gastight Doors — Designed for spaces requiring controlled sealing against gas or vapour transfer. Sealing performance, gasket materials and locking arrangements are defined according to the intended application.
