Our smoke protection doors are tested in accordance with EN 1634-3, have been issued building authority test certificates in accordance with DIN 18095-1 (only RS-1/2-62), and satisfy the requirements of future European standard specifications: S200 according to EN 13501-2. If a fire breaks out in a room, the smoke-protection doors tested in accordance with DIN 18095 are automatically closed by door closers. A special seal on three sides and the floor seal adapted to the particular application reliably protect against the penetration of smoke. Our smoke-proof steel door “RS-1/2”has a double-leaf door element, which is 62 mm thick and rebated on 3 sides. The door is equipped with corner frame 1.5 mm thick, with 3-sided seal and lower bottom threshold for sliding threshold seal in the door leaf. The galvanized and prime coated leaf and frame are similar to RAL 9002 (Grey white).
