In the security sector, genuine innovation is structural, driven identifying weaknesses, understanding how they are exploited, and engineering them out. For Warrior Doors, that philosophy has culminated in a sliding stainless steel security door that is quietly redefining high-risk entrances across the UK.
Designed and manufactured at the company’s Birmingham facility, Warrior’s single-leaf sliding security door has been developed around what it calls its proprietary Warrior Door Technology — an approach rooted in strength, durability and independently verified performance rather than adaptation of standard shopfront systems.
“It’s about removing weaknesses,” explains Managing Director Brett Barratt. With our sliding system, we’ve engineered out the hinge side completely. That changes the security dynamic from day one.”
Traditional swing doors carry inherent vulnerabilities. Hinge pins can be attacked, frames can distort under leverage and repeated heavy footfall accelerates wear at pivot points. Warrior’s sliding configuration removes the hinge line entirely, eliminating one of the most common forced-entry methods rather than simply reinforcing it.
“Hinge-side attack is one of the most common techniques used against traditional doors,” Barratt explains. “By removing the hinge altogether, we eliminate that vulnerability instead of trying to strengthen a weak point.”
The structural redesign is supported by independent third-party certification. Warrior’s stainless steel sliding doors are tested and certified by LPCB at BRE to LPS 1175 SR2 and SR3, as well as LPS 2081 SRB standards. They are listed in the LPCB Red Book, allowing specifiers, housing providers and retailers to verify performance independently.
“Anyone can claim performance,” says Barratt. “What matters is independent verification. Our sliding doors are LPCB certified to LPS 1175 and LPS 2081, and they’re publicly listed in the Red Book, trusted by Secure by Design. Specifiers don’t have to take our word for it — they can check it themselves.”
The company is also a Secured by Design member, aligning its products with the UK Police’s official crime prevention initiative and reinforcing their suitability for higher-risk environments including communal residential developments, high-value retail and critical public sector sites.
Material choice is central to the system’s long-term performance. Warrior’s sliding doors are constructed using sustainable, high-strength stainless steel framing designed to withstand both environmental exposure and sustained operational stress. Laminated or toughened security glazing is specified to the risk profile of the site, while high-security locking arrangements are engineered to resist forced entry attempts.
“We use stainless steel because these doors are designed to be installed once and perform for decades,” Barratt says. “It’s a buy-once philosophy. In communal housing, retail or public buildings, failure isn’t just inconvenient — it’s expensive and disruptive.” A growing frustration with local authorities is the rise in anti-social behaviour, we are busy replacing poor quality doors which have not stood up to their environments inside a few months or a year or two after being fitted. We have yet to replace a Warrior Door. Given the scrutiny of public spend, this is irresponsible to buy without considering the long term picture – its not sustainable, or fair to residents, to leave them unprotected when these are later disputed.”
Operational performance has been engineered alongside security. The single-leaf sliding action delivers smooth, controlled lateral movement, allowing continuous two-way foot traffic without the bottlenecks often associated with swing doors. The low-threshold design supports accessibility for wheelchair users and trolleys, ensuring inclusive access without compromising structural integrity.
“Sliding doors shouldn’t be a design choice or aesthetic preference,” Barratt adds. “In high-footfall entrances they manage traffic better, integrate more naturally with access control and avoid the wind and wear issues you often see with swing leaves. You gain operational efficiency as well as security.”
Increasingly, security doors sit at the centre of a layered access control strategy. Warrior’s sliding systems are designed to integrate seamlessly with proximity fob readers, card access systems, PIN keypads, audio and video intercoms, multi-occupancy entry systems and automated sliding operators with safety sensors.
“Modern security is layered,” says Barratt. “The door is one part of a wider system. Our sliding doors are designed to sit at the heart of access control, giving building owners control over who enters and when.”
Applications span communal residential apartment blocks, social housing, high-value retail shopfronts, education facilities, government buildings and defence-related or critical infrastructure sites. In each case, the fully glazed stainless steel framed design delivers a contemporary aesthetic that signals quality and security simultaneously — increasingly important for premium developments seeking to balance openness with resilience.
Warrior Doors emphasises that certified performance must be matched by proper installation and long-term aftercare. Every project begins with a detailed site survey and measured design process before manufacture in Birmingham. Installation is carried out by trained teams, followed by commissioning, testing and handover, with preventative maintenance and compliance support available to protect long-term performance.
“Our responsibility doesn’t end at manufacture,” Barratt concludes. “A security door is only as good as its installation and maintenance. That’s why we control the process from survey through to aftercare. Certification sets the benchmark — but delivery protects it.”
In a marketplace often driven by cost, Warrior Doors’ sliding stainless steel security door represents a shift towards engineered resilience and whole-life value. By combining proprietary design, UK manufacture and independently verified certification to LPS 1175 and LPS 2081 standards, the company has created a solution that is structurally different rather than superficially adapted.
In modern security architecture, resilience begins at the threshold — and increasingly, that threshold slides rather than swings.
