Nordor Technologies manufactures hinged, double-leaf and sliding fire doors in steel and timber at its workshop near Caen, and installs and maintains them on site. The company states that its doorsets hold NF certification as recognised by the arrêté du 22 mars 2004 — through AFNOR Certification for metal products and FCBA for timber — and carry CE marking to NF EN 16034, with classification reports issued by Efectis France following EN 1634-1 testing. Successor to the SMSL door brand, it equips nuclear sites including La Hague and CEA Cadarache.
