Security doors and physical security in Bristol

Bristol’s security map stretches from aerospace plants to harbourside apartments, taking in engineering, creative and university sites. ArxBridge supplies and installs rated security doors, shielding and glazing protection across the city, working with architects, contractors and consultants.

Engineering, technology and test facilities

Engineering and technology sites need protection for labs, test rigs and prototype stores. LPS 1175 security doors secure the rooms, while RF shielded rooms protect sensitive test environments from electromagnetic interference.

Shielding is specified by attenuation in dB over a frequency range, and it is verified after installation. Our testing and surveys service measures installed performance against the specification, so the room is proven, not assumed.

Where the threat picture includes deliberate attack on equipment, bullet resistant doors and glazing to EN 1522 and EN 1063 can be combined with the shielding in the same room.

Harbourside and creative quarters

The harbourside’s converted warehouses and new creative workspaces need security that suits brick and timber architecture. Rated doors in heritage styles, attack-rated glazing and discreet grilles protect without spoiling the character.

Ground-floor studios and galleries use retractable security grilles that vanish during opening hours. Service yards take security shutters and security gates.

Planning officers in conservation areas usually accept rated products that match the existing architecture. We supply the technical details the application needs.

Rating guide for Bristol sites

Use this as a starting guide. The threat assessment and the shielding specification set the final requirements for every room.

Test and research buildings often need the widest mix of ratings on one site. We schedule each room from the consultant’s specification, so shielding, fire and attack ratings are all covered.

Universities and research buildings

University estates combine historic colleges, science buildings and student housing. MRI shielded rooms need RF shielding, and RF shielding is different from magnetic shielding: many suites need both, verified after installation.

Secure meeting rooms for research partnerships use sound masking against eavesdropping, alongside LPS 1175 doors on the room itself. Education estates bring all of these needs together on one campus.

Shielding must be verified, not assumed. We test installed RF shielding and report attenuation against the specified frequency range, so the room’s performance is documented.

EMP protection for critical systems

Some Bristol technology sites need protection against electromagnetic pulse as well as everyday interference. EMP shielding goes beyond a standard RF room: power and signal entries must be filtered, or the pulse enters through the cables.

Testing and surveys verify the installed room against its specification. Where the risk assessment also calls for forced entry resistance, LPS 1175 security doors are built into the shielded envelope.

EMP protection is specified from a threat assessment, not from a catalogue. The assessment decides which rooms need it and what attenuation the shield must achieve across the frequency range.
