Heavy duty external fire doors and fire door maintenance

InterDam Merford fire doors constitute a heavy duty, fully certified range that covers fire ratings from A0 up to H120 including jet fire requirements. Doors are also able to withstand a blast overpressure (up to 2.5 bar blast).

Doors will be pre-assembled as complete units and provided with heavy duty special in-house designed hardware. For example, to meet the specific Norsok requirements we have designed a special mechanical opening device that ensures a maximum opening force of 5kg for heavy duty sliding doors, called the Ergo Latch©.

The door designs are versatile and can be adapted to meet our clients' particular requirements. Early consultation can result in a detailed design best suited to the overall platform design philosophy.

Our door range consists of Lloyds / DNV approved:

A 60 IDM single leaf hinged door
A 60 IDM double leaf hinged door
A 60 IDM single leaf sliding door
H 120 IDM single leaf hinged door
H 120 IDM single leaf sliding door
