Warrior Doors manufactures high-security, LPS 1175-certified aluminium doors engineered for the unique requirements of data centres, server facilities, colocation sites, and critical digital infrastructure.
Our fully glazed SR2 and SR3 Security Doors, SR3 Sliding Doors, and interlocking lobby systems deliver certified physical defence while supporting seamless access control and operational efficiency.
As one of the very few UK manufacturers offering fully glazed SR2 & SR3 doors and SR3-rated sliding security doors, Warrior Doors offers a level of capability unmatched in the UK market.
Our stainless steel data centre security sliding doors are designed for entrances where both security and accessibility are critical. Each single-leaf sliding door is engineered to providing a robust, reliable barrier against forced entry.
Data centres face evolving threats including targeted intrusion, hostile reconnaissance, insider risks and vehicle-based attempts. Warrior Doors helps operators protect:
Fully glazed SR2 and SR3 aluminium security doors.
These doors combine certified anti-intrusion performance with maximum visibility—ideal for security teams who depend on uninterrupted sightlines and CCTV integration.
Typical applications:
Internal secure areas
Security operations entrances
Controlled circulation points
Sliding doors are increasingly preferred in data centres due to:
Space efficiency – No swing path
High traffic capability – Staff & contractors
Fast controlled access – Works with card, fob, biometric systems
Excellent for interlocking systems
Reduced air disturbance – helpful in temperature-controlled facilities
Warrior Doors’ SR3 Sliding Door is specifically engineered for high-security technical environments.
Warrior Doors is a Birmingham-based manufacturer specialising in high security stainless steel doors. By designing and fabricating our single-leaf security sliding doors in-house, we maintain full control over materials, build quality and finishing.
Our team manages everything from stainless steel fabrication and glazing to powder coating and hardware integration. Every door is checked and tested before it leaves our facility, so you receive a security sliding door that is consistent, robust and ready for real-world use.
Each Warrior Doors stainless steel security sliding door is bespoke to your opening, risk profile and brand. Typical features include
Provides proven resistance against forced entry using advanced tools, delivering the level of physical security required for mission-critical digital infrastructure.
Engineered for seamless use within mantrap lobbies, airlocks and controlled-access zones that prevent tailgating or unauthorised entry.
Allows clear visibility for security teams and CCTV while maintaining exceptional anti-intrusion strength — a rare capability at SR2/SR3 levels.
Built for continuous use in busy data centres, with hardware, frames and mechanisms that maintain performance through constant daily cycles.
Designed to work with biometrics, PAC systems, encrypted readers, interlocks and monitoring contacts for precise, auditable control of all user movements
Can be integrated into protected entry vestibules and vehicle mitigation zones, reinforcing the door as part of a complete physical security strategy.
SR3-rated sliding security doors are ideal for data centres, providing certified protection while supporting high traffic flow, interlocking lobbies and advanced access control systems. Built for mission-critical environments, these doors ensure only authorised personnel move between secure zones without disrupting operations.
Secure glazed or solid SR2/SR3 doors at reception, staff or contractor entrances to control and monitor all access into the facility.
Use security doors to separate server halls, rack floors, network rooms and other high-value internal zones from general access areas.
Create controlled vestibule systems (airlocks) to prevent tailgating, piggybacking and unauthorised entry — ideal for high-security access control
Protect loading bays, service entrances and perimeter vehicle access points — integrating security doors with vehicle mitigation to safeguard against forced or vehicular intrusion.
Data Centre Security Doors provide LPS 1175 SR2/SR3 certified resistance to forced entry, far beyond what any conventional door can offer.
Unlike standard doors, fully glazed SR2/SR3 door sets maintain clear sightlines while delivering exceptional protection against attack.
These doors are designed to work seamlessly with biometrics, PAC systems and monitoring hardware, ensuring precise control over every user entering the facility.
Data Centre Security Doors enable secure mantrap and anti-tailgating systems that conventional doors cannot support.
Purpose-built for constant operation, including SR3 sliding models, they deliver smooth, reliable performance in mission-critical facilities.
Security doors integrate into fortified entry zones and vehicle mitigation systems, eliminating weak points in the building’s physical defence
Offers minimal resistance to forced entry and is not tested to any recognised security standard. This places your premises at risk by not using accredited, certified technology.
Uses basic glazing or solid panels that create blind spots and provide no certified protection against attack whereas the preference is for high strength visbility
Often incompatible with advanced biometrics or access systems, leading to unreliable or insecure integrations that put data, people and property at risk.
Cannot support controlled interlocking or anti-tailgating systems due to weak frames, hardware and tolerances.
Wears out quickly in 24/7 environments and causes operational bottlenecks due to limited cycle durability, requiring frequent repair/replacement
Standard Door: Creates vulnerable entry points and cannot be paired effectively with vehicle mitigation or hardened security zones.
