Birmingham-based manufacturer Warrior Doors has highlighted the critical role of UK manufacturing oversight in delivering certified stainless steel security sliding doors for high-risk environments, including critical infrastructure, defence industry sites and high-security public buildings. As demand for robust, fully certified entrances continues to grow across the UK, the company is positioning its Birmingham facility as a benchmark for quality assurance and independently verified security performance.
Warrior Doors designs and manufactures its single-leaf stainless steel security sliding doors entirely in house, combining precision-engineered stainless steel framing with high-performance laminated or toughened glazing. The result is a modern, fully glazed entrance that maximises visibility and accessibility, while providing a hardened barrier against forced entry in some of the most sensitive and demanding locations in the country.
Managing Director Brett Barratt says the company’s insistence on complete manufacturing oversight is central to its reputation for reliability. “When you are manufacturing security products that protect people, assets and national infrastructure, oversight is everything,” he explains. “By keeping every aspect of fabrication, assembly and testing under one roof in Birmingham, we maintain control over materials, tolerances and finishing. That means our customers receive a door that performs exactly as intended, not just in a test environment but in real-world operational conditions.”
This commitment to control and traceability is reinforced by Warrior Doors’ extensive programme of independent testing and certification. Its sliding doors are assessed by LPCB at BRE to LPS 1175 and LPS 2081 standards, and are listed in the publicly accessible LPCB Red Book, which provides external verification of a product’s security performance. The company is also an active member of Secured by Design, the national police crime-prevention initiative. Barratt says this level of independently validated security is essential when serving industries where the consequences of a breach are severe.
“In critical national infrastructure, in government facilities, in defence-related manufacturing and supply-chain environments, there is no room for uncertainty,” he says. “When a door is certified, listed in the Red Book and approved by Secured by Design, the client knows it has been tested under rigorous and repeatable conditions. That transparency keeps the marketplace accountable and gives organisations the confidence they need when procuring security-critical equipment.”
Warrior Doors’ stainless steel sliding doors are increasingly being specified for sites where high footfall and high threat levels intersect. In communal residential blocks, high-value retail units, healthcare estates, schools, local authority buildings and defence-sector facilities, the sliding mechanism offers a smooth, controlled movement that supports accessibility while also eliminating the hinge side, traditionally one of the most vulnerable attack points on a conventional swing door. This feature is particularly valued in critical infrastructure and defence settings, where resistances to common forms of attack must be predictable and repeatable.
Each door is manufactured to measure at the company’s Birmingham facility, where teams oversee stainless steel fabrication, glazing, powder coating, locking-system integration and automation compatibility. Installation, commissioning and maintenance are also carried out by Warrior Doors’ own trained engineers, ensuring consistency between the door tested in the laboratory and the door ultimately installed on site. According to Barratt, maintaining control over installation is as important as the integrity of the manufacturing process itself. “A security door’s effectiveness can be compromised by poor installation. We ensure the door performs exactly as the certified specification demands, whether it is protecting a block of apartments, a high-value retailer or a classified defence-sector facility.”
Barratt believes that the company’s Birmingham location continues to strengthen its manufacturing ethos. “Birmingham’s engineering heritage gives us a unique advantage,” he says. “We have access to a regional talent base that understands precision manufacturing and takes pride in producing security doors that are ready to protect people and critical assets. Customers value the traceability and accountability that comes with UK manufacturing, particularly in sectors where security standards are non-negotiable.”
For organisations seeking verified protection, Warrior Doors makes all relevant LPCB certificates, Red Book listings and Secured by Design approvals publicly available. Barratt says openness is essential in an industry where quality varies widely. “This is about giving clients confidence,” he notes. “If you’re securing critical national infrastructure, defence facilities or essential public services, you need clear, independently validated evidence of performance. Manufacturing oversight and certification sit at the heart of that trust.”
