Using our standard high-quality galvanised steel fully-welded frame and a wooden fire door with the standard intumescent strips and sealers, the door and frame failed after 38 minutes in the standard 30-minute test at the Warrington test centre.
Therefore, the combination of an easy-to-fit metal door frame and a wooden fire door are unique to KLM engineering.
With our proven engineering, we put the safety of our valued customers first and foremost.
When it comes to composite doors manufacturers, could you expect this level of safety from anyone but KLM Engineering?
