Steel Hinged Doors

Level 4 High Security Steel Hinged Doors

With Safety and Security increasingly becoming a concern across the UK, Tomahawk Doors offer our most secure and highest anti-cut rated LPS 1175 level 4 tested steel hinged door that is available in single or double doors (outward opening only). The LPCB have tested our level 4 steel hinged door to withstand attack and unauthorized entry with heavy duty & power tools for up to 30 minutes. A large variety of locking systems can be specified including manual and electric as well as a limited choice of glazing units, louvre panels and removable transoms are also available.

Our Level 4 high security steel hinged door is the next step up from our level 3 high security steel hinged door and offers added security with the attack side made from 1.5mm zintec steel with a 2mm drill resistant steel plate sat behind the zintec sheet and the back face out of 1.5mm zintec steel giving it that more added protection to the level 3 high security door with the anti-cut facility. The Tomahawk LPS 1175 level 4 door can be found in many high security locations such as schools, universities, leisure facilities, retail outlets, banks, MOD buildings and sub stations.
