STEEL FIRE RESISTANT DOORS DFM DS

TECHNICAL SPECIFICATION OF FIRE RESISTANT DOORS DFM DS EI30 EI60

FIRE RESISTANT DOORS EI 30 DFM DS

Fire resistant doorsets and wall hatches DFM DS are characterised by disctinctly stiff construction. The door leaf is built up of two steel skins 0.75 mm thick edged with rigid rebate 18 x 18 mm, and is peculiarly light due to special filling- rockwool 120 kg/m3. Total thickness of door is 65 mm and weight- 25 kg/m2.
Door leaves up to 2500 mm are hung in aluminium moulded frame with minimum 2 pcs of stainless steel hinges of class AISI 304 according to EN 1.4301.

Altogether this minimised construction causes less operational forces working on the doors’ hinges, lock, door closers, this having a direct positive effect on enhanced functional durability.

FIRE RESISTANT DOORS EI 60 DFM DS

Fire resistant doorsets DFM DS and wall hatches are characterised by distinctively stiff construction. The door leaf is built up of two steel skins 0.75 mm thick edged with rigid rebate 18 x 18 mm, and is peculiarly light due to special filling- rockwool 140 kg/m3. Total thickness of door is 65 mm and weight- 27 kg/m2.
Door leaves up to 2500 mm are hung in aluminium moulded frame with minimum 2 pcs of stainless steel hinges of class AISI 304 according to EN 1.4301.

Altogether this minimised construction causes less operational forces working on the doors’ hinges, lock, door closers, this having a direct positive effect on enhanced functional durability.

DOOR FRAMES

Steel doors DFM DS  are standardly fitted in with aluminium moulded frame.
This ingenious solution effects in high aesthetics and quality of installation of door frames in all wall types.

Standard model of frame is angled- corner type. Optionally, rectangular and wall embracing frames are available, these additionally in variant of warm frame (thermal break)
The undisputable advantage of such door frame construction accompanied by the rigid rebate of door leaf results in noticeable minimising of structural opening required for installation of fire doors.

Additionally, contrary to typical steel frame, aluminum frames are not jeopardised with corrosion if installed in exterior or in wet rooms. Aluminum frames are also characterised by ultimate quality of making due to no-welding corner connection technology.
As standard, door frames are powder coated to RAL palette, however, customised anodised models are also provided on request.

INSTALLATION

Installation of doors DFM DS is innovative due to light and at the same time rigid aluminium door frame.

Contrary to standard typical steel frames, our aluminium frames are not load bearing elements of doors. 2 of total of fixing studs are fitted through the hinges. The stud is settled in wall construction through a steel plate affixed in door frame and takes over some load off the door leaf.

The advantage of such installation is elimination of tensions and deformations typical for steel frames as well as aesthetics of final looks (the studs are invisible)
