A15 Steel Fire Door

A15 Steel Fire Door

Ensure the highest level of passive fire protection on your vessel with our premium marine steel fireproof doors. Engineered to contain fire and prevent its spread, these high-quality doors are essential safety components for any ship or offshore installation. Constructed entirely from steel, they are designed to meet the rigorous fire division standards required in modern maritime construction.

Our ship fire doors are available in multiple fire resistance classes, including A60, A30, A15, A0, B15, and B0. This range allows you to select the exact level of protection needed for different areas of the vessel, from high-risk zones to general accommodation. The doors are specifically designed for installation in locations with A-class or B-class fire divisions, such as cabin entrances and alleyways.

To maximize functionality without compromising safety, these marine fire doors can be customized with a variety of fire door accessories. You can choose to integrate escape ports (for emergency passage), ventilation grills (for airflow), fire holes (for fire hose access), and fire windows (for visibility). Please note that these doors are designed for interior use and are not applicable to areas such as outer walkways or open deck houses.

Frequently Asked Questions (FAQ)

1. What is the difference between an A-class and a B-class fire door?
The difference lies in their ability to resist fire and heat passage.

• A-class fire doors (A60, A30, A15, A0) are constructed of steel and must be capable of preventing the passage of flame and smoke for 60, 30, 15, or 0 minutes respectively. Crucially, they must also be insulated with fire-resistant material so that the average temperature on the unexposed side does not rise significantly.

• B-class fire doors (B15, B0) are also constructed of non-combustible materials but have lower insulation requirements. They must be capable of preventing the passage of flame for 15 or 0 minutes, but the temperature rise on the unexposed side is less restricted.

2. What are the standard accessories available for these marine doors?
We offer several functional accessories that can be integrated into the door leaf:

• Escape Port / Escape Louver: A small, quick-acting door within the main door, often used for emergency escape or passing fire hoses.

• Ventilation Grill / Ventilation Louver: Allows for airflow through the door while maintaining the fire rating when closed.

• Fire Hole / Fire Hose Hole: A small hinged or spring-loaded flap that allows a fire hose to be passed through without opening the main door.

• Fireproof Window: A glass installation rated to the same fire class as the door, allowing for visibility.

3. Where should these fireproof doors be installed on a vessel?
These doors are specifically intended for interior applications where fire division standards are required. This includes cabins, alleyways (corridors), stairway enclosures, and machinery space boundaries. They are not applicable for exterior areas exposed to the weather, such as outer walkways, open deck houses, or bulkheads directly exposed to the sea.

4. What certifications do you provide for these fire doors?
Our marine steel fireproof doors are manufactured to meet the requirements of SOLAS and the International Code for Application of Fire Test Procedures (FTP Code). They can be supplied with type approval certification from major classification societies, including CCS (China Classification Society), BV (Bureau Veritas), EC (European Community), and ABS (American Bureau of Shipping) , as specified in your project requirements.

5. Can you manufacture doors in non-standard sizes?
Yes, customization is a key feature of our service. The table provides standard dimensional ranges (e.g., Clear Size L: 1500-2000mm, B: 500-1000mm). However, we can manufacture custom door sizes to fit specific bulkhead cutouts and design requirements. Please provide your exact “clear opening” dimensions and bulkhead thickness when requesting a quote.
