Fire and blast resistant

sliding Doors

Our heavy duty sliding doors are available for all fire ratings in accordance with the IMO FTP code and SOLAS 74. All of our heavy duty sliding doors have been extensively tested and approved by Lloyd’s Register, DNV-GL, ABS and USCG.

Our door range consists of the following heavy duty door types:

  • A0 / A60 rated single leaf sliding door
  • H0 / H60 / H120 rated single leaf sliding door

Nowadays, besides fire- and blast protection, there is a rising demand for bullet resistance. With some modifications inside the doorleaf, we can make our doors bulletproof until BR7 class.

InterDams’ sliding doors incorporate a heavy duty sliding mechanism – a stainless steel railing system with supports and rollers – and include standardly-provided heavy duty hardware such as stainless steel door handles and a hook latch. Sealing around the doorframe ensures a weathertight fit for the entire unit.

Cost-effective Ergo Latch© Design
To meet specific Norsok requirements for our heavy duty sliding doors, we have designed a special mechanical device that ensures a maximum opening force of 50N. This opening device is called the Ergo Latch©, and it operates like a standard door handle. It reduces purchase and maintenance costs – you won’t need special pneumatic or electrical opening systems to comply with Norsok opening force requirements – and it fits doors from all heavy duty door manufacturers.

Pneumatic/electric opening system
We have also developed our own pneumatic and electric opening system for all sizes of heavy duty sliding doors.
