Olfen has steel halls, ventilation runs and load-bearing structures that must keep their function under fire. We install, renovate, document audit-ready.
Unlike fire doors or seals, claddings don't form compartments — they buffer temperature. The steel beam, the duct, the timber stays load-bearing under fire for the defined duration. In Olfen, this matters most in public buildings where a beam collapse means a section collapse.
What we install in Olfen depends on the structure, appearance and construction phase.
