Ninz is Italy’s largest manufacturer working solely on fire doors, producing the Proget, Univer and Rever ranges from Ala in the Vallagarina. Its published product data gives the EN 13501-2 fire classifications directly — the Univer range is listed at EI2 60 and EI2 90 CE and Proget at REI 60, REI 120 and EI2 60 CE, the CE suffix marking the doorsets certified under EN 16034. Every door is supplied with a dichiarazione di conformità, an Italian omologazione and an installation, use and maintenance booklet, and the firm runs a per-door certificate lookup keyed to the production data stamped on the leaf. The individual certificate numbers and the notified body sit behind that lookup rather than on the public site.
