Secure Entrance Door Sets are purpose‑engineered security doors designed to protect controlled environments, high‑risk facilities and sensitive operational areas. Built for strength, stability and seamless integration, they provide a hardened access point that resists intrusion, supports operational control and delivers long‑term reliability in demanding environments. Each door set forms a critical element of the physical security envelope, ensuring that entranceways are protected to the same standard as the surrounding secure structure.

Developed for defence sites, utilities, nuclear facilities, data centres, secure commercial operations and specialist technical spaces, Secure Entrance Door Sets are built to withstand real‑world security demands. Heavy‑duty construction, reinforced frames and secure locking interfaces ensure that the door performs consistently where controlled access and asset protection are critical. Designed for both internal and external use, each door set offers robust functionality without compromising appearance or usability.

Secure Entrance Door Sets integrate seamlessly with Singular Security’s Modular Walling, Enclosure Systems and Aperture Protection products, enabling a complete, cohesive approach to secure‑facility design. Whether installed as part of a new build or retrofitted into an existing environment, these door sets deliver reliable protection and operational confidence.

For environments where independently tested forced-entry resistance is required, security door sets can be specified to recognised standards such as LPCB LPS 1175.

LPS 1175 is one of the most widely referenced physical security standards in the UK, assessing the ability of doors, barriers and security products to resist attack using defined tools and attack methodologies. Products that have successfully completed LPCB testing provide specifiers with a recognised benchmark for evaluating security performance.

LPCB LPS 1175 security door sets are commonly specified within:

• Defence and government facilities
• Critical national infrastructure
• Utilities and energy sites
• Nuclear and industrial environments
• Data centres and communications facilities
• Secure commercial buildings

By combining reinforced construction, secure locking systems and independently tested performance, LPCB LPS 1175 rated door sets help ensure that access points provide a level of protection aligned with the wider security requirements of the facility.

Where projects require certified entrance protection, suitable LPCB LPS 1175 security door sets can be incorporated into a wider physical security strategy alongside access control, surveillance, monitoring and protective infrastructure.

Secure Entrance Door Sets provide reliable protection and controlled access across a broad range of critical environments, including:

• Defence facilities, armouries and operational command spaces
• Utilities, substations, control rooms and remote infrastructure sites
• Nuclear, radiological and hazardous‑material facilities
• Data centres, server rooms and network distribution nodes
• Laboratories, cleanrooms and specialist technical environments
• Airports, rail infrastructure and logistics hubs
• Retail back‑of‑house spaces and high‑value storage rooms
• Residential secure rooms, safe rooms and private armouries

Whether your project requires a secure internal access point, a high-security external entrance, or an LPCB LPS 1175 rated security door integrated within a wider protection strategy, Singular Security can help identify the right solution for your operational and security requirements.

Our team can advise on door configurations, security performance requirements, access control integration, and compatibility with wider physical security measures to ensure a cohesive and effective solution.
