Backlinks HubProtecting a commercial, industrial or public building requires more than alarms and CCTV. Doors are among the most important physical barriers between valuable assets and potential intruders, which makes their construction and security performance an important consideration.
In the UK, certified steel security doors provide building owners and specifiers with independently assessed evidence of how a doorset performs against particular threats. Understanding certification can therefore make it easier to choose appropriate protection rather than relying solely on a manufacturer’s security claims.
Why Certification Matters
A steel door may appear extremely strong, but appearance alone does not establish how well it will withstand an attempted break-in. Security certification provides a more objective way of assessing performance.
Independent testing subjects products to defined attack methods under controlled conditions. Certification can also involve ongoing oversight to confirm that products continue to meet the relevant standard. For organisations comparing steel security doors, checking the standards and certifications applying to a specific doorset can provide valuable information about its suitability.
Understanding LPS 1175
LPS 1175 is one of the important security standards encountered in the UK. Developed by the Loss Prevention Certification Board, it assesses the resistance of physical security products to unauthorised access.
The current Issue 8 approach uses security ratings that reflect both the tools used during an attack and the minimum delay provided by the product. This allows specifiers to select protection appropriate to the anticipated threat rather than assuming every building requires the same security level. Higher-security environments may require doorsets tested against more capable tools or longer attack periods.
What About PAS 24?
PAS 24 is another standard commonly associated with door security in the UK. It sets enhanced security performance requirements for doorsets and windows and uses a combination of mechanical loading and manual intervention testing.
LPS 1175 and PAS 24 should not simply be viewed as interchangeable ratings. They address security performance in different ways, so the appropriate certification will depend on the project, risk assessment and specification.
Consider the Complete Doorset
Security depends on more than the steel used to manufacture the door leaf. The frame, hinges, locks, glazing, louvres and other components can all affect resistance to forced entry. This is why buyers should examine certification for the complete doorset and its chosen configuration. Adding hardware or altering a tested design without confirming that the change is covered by certification could affect the expected security performance.
Match Security to the Building
Not every property faces the same risks. A general commercial building may have very different requirements from a data centre, utility site, warehouse containing high-value stock or critical infrastructure facility. Before selecting security doors, consider the value of the assets being protected, likely methods of attack, location of the entrance and other security measures already in place. The door may also need to satisfy additional requirements, such as fire resistance, emergency escape, ventilation, acoustic performance or weather protection.
Installation and Maintenance Are Essential
A certified doorset still needs to be installed correctly. Poor installation could create weaknesses around the frame or prevent locks and other hardware from operating as intended. Maintenance is equally important once the doors are in use. Hinges, locks, closers and access-control components should be inspected regularly, with damage addressed promptly.
Choosing With Confidence
Certified steel security doors provide something that an untested security claim cannot: independently assessed evidence of performance against defined criteria. For UK building owners and specifiers, the most effective approach is to identify the risks associated with each entrance and then select a complete doorset with suitable certification. Combined with professional installation, regular maintenance and other appropriate security measures, certified steel doors can form a robust first line of physical protection.
