Security doors - fortidoor
FortiDoors offers custom manufacturing of special security doors.
We manufacture safety anti-pressure doors. These are one of the most important elements of any civil defence shelter or other protective structure. They can protect against pressure waves, gunfire, explosions and the intrusion of chemical and biological warfare agents, including radiation.
FortiDoor anti-pressure doors are designed for simplicity, reliability and minimal maintenance. A range of options are available including motorised/remote operated mechanisms, special hinges for everyday use and other safety features.
The standard safety door is designed to withstand multiple long-term pressure loads with reflected pressures from 2 bar (200 kPa) to 18 bar (1800 kPa). Ballistic resistance from FB2 to FB7 Level4.
We offer a wide range of pre-engineered standard doors with varying levels of blast resistance that are designed to stop the progression of pressure waves through penetrations into protected areas in civil defence and military blast resistant shelters.
Our doors are made of structural steel with solid homogeneous steel plates, ballistic plates ARMOX, RAMOR, can be opened and closed manually from both sides, are equipped with safe locking systems. The recessed design of their frames allows for easy installation in reinforced concrete walls, and the door sheet/frame assembly is made of an optimized pattern that transfers any compressive force to the surrounding walls.
Our standard doors are available in a wide range of sizes and as single or double leaf doors. We offer custom manufacturing to your specifications.

Civil Protection Shelter Doors

It is the treatment of exterior or interior doors with ballistic protection (also applies to partially glazed doors), which is a ballistic plate that ensures the bulletproofness of the door in ballistic resistance FB2, FB4, FB6.
In this context, the existing door frame construction should be assessed and, if necessary, adapted to the increased weight of the door leaf. In addition, the door will be fitted with security fittings whereby the outside of the door will not be a handle but a ball, making it impossible for an attacker to open the door. A mechanical or electronic lock (deadbolt) may be additionally installed on the inside of the door, which will be closed in the event of an emergency. This additional internal lock will ensure that the possibility of the door being forced open is eliminated.
From any existing door, we can make an impregnable and bulletproof door at a fraction of the cost of a new ballistic door.
Doors with ballistic resistance FB2, FB4, FB6, FB7 Level 1 to Level 4
We carry out revitalization of existing doors in civil protection shelters. These are light (steel) back pressure doors, heavy (steel, concrete) back pressure doors, emergency hatches and hatches.
- Door frames
- Door leaves
- Panty
- Closing levers
- Seals
- Pressure relief valves

Anti-pressure garage door

We manufacture safety pressure relief measures for residential buildings. These are anti-pressure garage doors, which perfectly and safely close the main entrance to the underground garage and thus create a short-term shelter for the inhabitants of the house. The special door is always in an open state and only closes (mechanically or electronically) in the event of an emergency. Our largest garage doors reach up to 6m in length with a thickness of 35cm.
Safety hatch hinged
This is a standard hatch design that opens upwards. The installation of such a hatch should be carried out in a non-overhanging area.
Pressure hatches are primarily designed to stop the progression of the pressure wave, but are also airtight to prevent the entry of toxic substances. All hatches are designed for simplicity, reliability and minimal maintenance.
The hatches withstand a pressure of 2 bar (200kPa) and have ballistic resistance FB4, FB6 according to FB/BR according to EN 1522,1523, TBO according to EN 395360
- construction made of high quality solid SM steel
- ARMOX ballistic plates
- locking levers 2 to 4 pieces
- seals to ensure gas tightness
- internal protected hinges
- hatch shapes square, round
- standard dimensions 600,700,800,900,1000 mm
- possibility of customized production

Safety hatch hinged
It is designed in such a way that the lid of the hatch does not lift upwards when opening, but opens downwards, which helps to open the hatch in the event of a possible cave-in and allows protected persons to leave the shelter.

Sliding safety cover
It is designed in such a way that the lid of the hatch does not lift upwards when opening, but opens sideways. The main advantages include the invisible opening of the hatch on uncovered land. The biggest advantage is that debris such as house debris or other materials can fall on the hatch, which would make it impossible to open with conventional upward opening hatches. In this design, the lid of the hatch slides into its own housing. In the event that a several tonne load of debris falls on the hatch, the hatch lid can simply be released and the lid drops into the escape passage.

Security shutters, ballistic resistance, radiation protection
If you need to secure a room that is not underground and has windows, this is not impossible either.
