What sets Heinen apart is that every performance available on our steel doors is also available in stainless steel: fire resistance up to EI<span class=\"s1\">\u2082<\/span> 240, burglar resistance up to RC5, acoustic insulation, weather-tightness and heavy-duty use \u2014 with no compromise.

However, some technical accessories are not available in stainless steel, in particular certain door closers or specific equipment.
