Space-saving with high performance, plug&play, no wiring required and minimum interfaces.

Our customers benefit from the reduction to one single interface in order processing, significantly minimised effort due to:

  • Established processes and partnerships ensure solution-oriented engineering and on-time material procurement.
  • Our technicians are highly competent, friendly and weatherproof when installing and maintaining our systems, including offshore.
  • Due to our close cooperation with international insurers, we always find a safe solution during inspections.
  • Our documentation is precise, understandable and functional.

We are a system supplier and NFPA member.

Base Frame
Base Frame
  • made of self-developed edge profiles
  • completely hot-dip galvanised in a full bath, according to DIN EN ISO 1461 with a protection duration class C3
  • Due to steel sheets with increased material strength and corresponding construction, a considerably higher torsional stiffness is achieved than with comparable sectional steel base frames
  • On request divided for better handling on the construction site

On request with SCHALLEX – structure-borne sound insulation
