Load-bearing structures keep their fire-resistance rating through approved board claddings, fire-protective coatings or mineral-wool build-ups — installed in Hennef and Region Regierungsbezirk Köln.
Unlike fire doors or seals, claddings don't form compartments — they stabilise load-bearing structures. The steel beam, the duct, the timber stays load-bearing under fire for the defined duration. In Hennef, this matters most in car parks where a beam collapse means a section collapse.
What we install in Hennef depends on the structure, appearance and construction phase.
