DFM OS swinging fire doors

door leaf characteristics

Steel fire swing gates of DFM OS type are made as rebated gates with thick rebate and pressed from two steel sheets of 0.75mm thickness. They are made as double-leaf. The weight of the sash, which is lowered in comparison with traditional designs, has a beneficial effect on reducing the operating forces acting on the structure.

In the basic version, wings and frames are powder-coated in any RAL color. Gate type DFM OS are also available as a gate without fire resistance and as external gates.

The gates in the standard version are equipped with:

  • latch and lock,
  • a set of stainless steel handles of the U-form type on a sign,
  • cylindrical cylinder with a set of 3 keys,
  • 3 or 4 3D adjustable stainless steel hinges (per sash),
  • 2 anti-balance pins (per sash),
  • rubber gasket and intumescent seal.

Optional equipment:

  • door closers in accordance with EN 1154,
  • stainless steel handles,

  • ventilation grilles,
  • bumpers (kick-plate) made of stainless steel
  • Holders and electromagnetic jumpers,
  • thresholds or self-climbing slats.
