ATI Dainese fire doors, with one or two leaves, are REI 120 and REI 60 certified, according to Italian UNI 9723 standards. REI doors consist of a frame in “Z” shaped pressed galvanised steel profile 15/10 mm thick, and door leaf flush with the frame made of double galvanised steel sheet packed with high density insulating material. The hinges are made of steel with double ball bearings. The closing mechanism is spring-loaded, inserted in the adjustable hinges and invisible from the outside, while a hinge bolt is fitted between the two hinges. The door is equipped with a fireproof lock complete with cylinder and keys. On the secondary leaf, there is a self-locking latch with lever handle. The handle is made of black PVC with steel core, U-shaped against accidental snagging and there is an intumescent gasket on the frame. Finishing is with epoxy-polyester powder coating, embossed according to our standard. The leaf rebate is 19 mm deep to limit the risk of injury in the event of a collision with people.
