LPS 1175 SR3 at the perimeter. SR4 on the data hall envelope where the tier rating demands it. Mantrap pairs at the staff entries. EMC and TEMPEST shielded fabric on the highest-classified tiers. We manufacture the steel core for the doors and windows protecting every uptime layer.
Data centre physical security is the outermost layer of a much wider data security framework. The door fabric has to do its job without becoming the weak link in a system that also includes biometric access, video surveillance, intrusion detection, and the operational security policy that wraps all of it.
Fort Engineering manufactures for hyperscale operators, colocation providers, telecommunications carriers, financial sector data hall estates, and the edge data centre operators building out the next layer of the network. Same factory, same engineering team, same certification scheme for a 100-rack edge facility as for a hyperscale campus.
The tier rating differs. The manufacturing standard does not.

Threats and response
The three security scenarios that drive most data centre procurement, and the manufacturing response that handles each.
01 / Scenario
The outer ring of the physical security framework. SR3 as the campus boundary and gatehouse baseline, with SR4 on the data hall envelope where the tier rating calls for it. LPCB-tested fabric, third-party verified attack resistance.
LPS 1175 SR3-SR4
02 / Scenario
Mantrap door pairs at staff and contractor entries – interlocked, single-occupancy enforced. Dual-occupancy detection integration. Biometric reader integration into door fabric rather than bolted on. Audit-trail-ready.
Mantrap pairs · Biometric-ready
03 / Scenario
The genuinely data-centre-specific concern. Faraday-cage door fabric, suppressed emissions, shielded gasket sets. EN 50147 attenuation testing on request. Specified where the data classification or the regulated environment demands it.

Products that fit
Most data centre projects pull from these two product lines. Hyperscale halls are mostly windowless on the hall envelope, so window applications concentrate at the perimeter and admin block.
01 / Capability
LPS 1175 SR3-4 across perimeter, mantrap pair, and data hall envelope applications. EMC and TEMPEST shielded variants with integrated gasket sets. Biometric reader cutouts and cable routing designed in rather than retrofitted. Audit-trail-grade hardware.
02 / Capability
Fixed glazing as standard at perimeter and admin block. Ballistic glazing options where the threat assessment requires it. EMC shielded glazing on the higher tiers with attenuation testing on request. Matched window resistance to the door spec across the same SR range.

Detail
LPS 1175
Perimeter and data hall envelope. SR3 on the campus boundary, SR4 on the hall door fabric where the tier rating or the customer classification requires it.
Uptime Institute
Tier classification reference for the wider facility. Physical security is one input among many – power, cooling, redundancy. SR-rated fabric supports the physical perimeter requirements.
Tier reference
EN 50600
European data centre infrastructure standard. Sections on physical security and protection against environmental threats. Referenced on most European hyperscale and colocation procurement.
EN reference
EN 50147 / TEMPEST
Attenuation testing for shielded enclosures (EN 50147). TEMPEST classifications for emissions suppression. Specified on regulated and classified data environments.
EN reference
The four rows above are the standards a data centre procurement team will check first. Project-specific specifications may layer on others – environmental (IP / IK ratings), fire compartment, ISO 27001 alignment on the wider security framework. The LPS 1175 page covers the most-asked-about rating in detail.

Selected projects
Case studies for the data centre sector are in preparation. Selected hyperscale, colocation, and edge data centre projects will appear here as they’re cleared for publication – many remain under NDA. In the meantime, the full case studies index covers projects across all six sectors.
Fort Engineering manufactures. Hyperscale, colocation and edge data centre procurement is fulfilled by Fort Security Doors, our commercial customer brand.
