Contemporary projects - from prestigious residences to public buildings and institutional headquarters - require protection that is not limited to meeting minimum standards. Investors and architects expect solutions that combine the highest classes of security, long-term reliability and design without compromise. The DFM DEFENCE line of doors from DFM Polska was created precisely to "protect more than space". - provide peace of mind, risk control and aesthetics that harmonize with the architectural concept.

DFM DEFENCE - the answer to real
design challenges

DFM brand portfolio

The DFM Polska portfolio includes steel doors (including large-format doors) and Forster system doors and profile walls, available in burglar-resistant RC2-RC4, bullet-resistant FB4-FB7 and fire-resistant EI30-EI120 classes.

Product characteristics

Additional options - such as smoke tightness, high mechanical durability or solutions dedicated to the implementation of access control - allow you to precisely match the product to the security scenario and functional requirements of the future user.

Steel door DFM DS RC4 FB4-1S
- DFM's flagship offering

In the segments with the highest requirements, the DFM DS RC4 FB4-1S model stands out in particular : a steel door with a leaf thickness of 65 mm, with a thick rebate, combining the features of FB4 bullet resistance, RC4 burglary resistance and EI₂ 90 fire resistance. The structure is based on 0.75-0.9 mm steel sheets for the sash and 1.8 mm for the frame; the filling is lightweight, durable mineral wool. Standard features include INOX 304 hinges with 3D adjustment, a multi-point slat lock, intumescent seals and self-closing slats. Options are also available for electromotive locking adapted to distance control systems and equipping doors with surface-mounted door closers (according to EN 1154).

DFM DEFENCE combines technical parameters with flexibility of form.
Forster systems are available for single and double-leaf doors,
full or glazed, as well as fixed walls and sets with fanlights.

Profiles powder-coated in any RAL color (other palettes on request) or made of stainless steel with an aesthetic cut allow consistency with the material and color palette of the project. Fillings are selected according to the target resistance class - burglar-proof (according to EN 1627) or bullet-proof (according to EN 1522/EN 1523; glass according to EN 1063) - with the possibility of improving acoustic and thermal parameters. Fire- and smoke-resistant variants are available in both steel and profile solutions.

Of particular interest to architects are the Forster UNICO configurations (available in RC2-RC4 burglary and FB4-FB7 bullet resistance classes, also for exterior use) and Forster Fuego Light (a combination of EI30 and FB4-NS in fire doors). Thanks to them, it is possible to design modern glazing with increased protection, without sacrificing the slenderness of the profile and purity of detail.

Examples of applications:
from special-purpose buildings
to modern offices

The DFM DEFENCE product line meets the needs of:

diplomatic facilities and financial institutions - ballistic protection (FB4-FB7), a high level of access control and burglar-proof parameters are required; Forster profile structures perform well in customer service areas, offices and corridors with large glazing, combining transparency with security;
office buildings, management and data processing centers - fire resistance (EI30-EI120), smoke tightness, mechanical durability and integration with evacuation (EN 179/EN 1125) and access control systems are key; steel and profile solutions can perform fire zoning functions while maintaining a consistent architectural language;
premium residences - steel doors in RC2-RC4 classes, complemented by acoustic and thermal parameters, provide comfort, privacy and discreet security, while wide finishing options (including woodgrain surfaces) allow them to be harmoniously integrated into the aesthetics of interiors;
military and special-purpose facilities - such as command centers, protected areas, arms depots or critical infrastructure, where the highest classes of ballistic protection, resistance to forced entry and the ability to design solutions tailored to individual threat scenarios are crucial; in this type of realizations, DFM DEFENCE offers structures with increased durability, compatible with advanced security systems;
museum buildings, archives and collection storage facilities - spaces requiring special protection of property of high cultural and historical value, where not only burglary and fire protection parameters are important, but also access control, durability and the ability to combine security with aesthetics neutral to the exhibition and historic architecture.
