LPS 1175 Swinging Security Doors

LPS 1175 swinging security doors are designed for buildings where resistance to forced entry is essential but access must remain practical and reliable for everyday use. In many commercial and public environments the entrance door is the first point an attacker will target, which means its performance is critical to the overall security of the building.

Unlike standard commercial doors, LPS 1175 rated doors are independently tested to ensure they can withstand physical attack using defined toolkits and methods. The certification applies to the entire door assembly rather than just individual components, meaning the leaf, frame, hinges, locking system and fixings all work together as a tested security system.

At Premier SSL, we manufacture and install LPS 1175 certified swinging security doors engineered for demanding environments where both durability and certified protection are required.

LPS 1175

LPS 1175 is the UK’s most widely specified standard for resistance to forced entry.

LPS 1673

LPS 1673 specified standard for resistance to forced entry.

What is LPS 1175 Certification?

LPS 1175 is one of the most widely recognised physical security standards used in the UK and internationally. It is developed by the Loss Prevention Certification Board (LPCB) and focuses on resistance to forced entry.

During testing, engineers attempt to break through the door using a range of tools and techniques that simulate real world burglary methods. The door must resist the attack for a specified period of time depending on the security rating achieved.

Rather than testing individual parts, the certification evaluates the complete door system, including:

  • Door leaf construction

  • Frame structure

  • Hinge assemblies

  • Locking hardware

  • Mechanical fixings

This approach ensures that the door performs as a complete security barrier when installed on site.

Understanding LPS 1175 Security Ratings

LPS 1175 doors are classified using Security Ratings (SR). Each rating corresponds to the type of attack tools used and the level of resistance required.

Lower ratings typically protect against opportunistic attacks using simple tools, while higher ratings are designed to resist more determined attempts using heavier equipment.

Common ratings include:

SR2: Provides protection against opportunistic attack using basic hand tools. Often specified for commercial premises and public buildings.

SR3: Designed to resist more determined attacks using a wider range of tools. Suitable for higher risk commercial environments and infrastructure facilities.

SR4 and above: Used for environments where a higher level of protection is required, such as secure infrastructure or sensitive facilities.

Selecting the correct rating normally depends on the building risk assessment and the wider security strategy.

Where LPS 1175 Swinging Doors Are Used

LPS 1175 swinging security doors are widely specified across both public and private sector projects. They are particularly useful where access must remain simple for daily operation but security cannot be compromised.

Typical applications include:

  • Data centres

  • Utility buildings and substations

  • Commercial offices

  • Cash handling facilities

  • Transport infrastructure

  • Secure service entrances

  • Healthcare and public buildings

In these environments the door must withstand attempted forced entry while continuing to operate reliably under frequent use.

Construction of LPS 1175 Security Doors

The strength of an LPS 1175 door comes from the combination of its structural design and the hardware used.

Door leaves are typically manufactured using reinforced steel or stainless steel construction with an internal core designed to resist bending or deformation under attack. Frames are engineered to anchor securely into the building structure, preventing the door from being levered out of position.

Heavy duty hinges and integrated dog bolts help prevent the door being forced away from the frame, while multi point locking systems distribute locking forces across multiple areas of the door.

These elements work together to create a door assembly capable of resisting sustained attack.

Automation and Access Control

Many modern buildings require automated entrances or integration with electronic access control systems. LPS 1175 swinging doors can often be configured to support these requirements without compromising their certification.

Automatic operators, access control readers and electronic locking systems can be incorporated into the design provided they are installed in accordance with the certified specification.

This allows the entrance to remain both secure and easy to use, particularly in high traffic environments such as hospitals or transport facilities.

Security Without Compromising Appearance

Security doors do not have to look industrial or intrusive. Many projects require a clean architectural appearance, particularly in public buildings or commercial developments.

LPS 1175 swinging doors can be manufactured in a wide range of finishes and colours to match the surrounding façade. Glazing panels can also be incorporated using laminated or security rated glass systems that are compatible with the certification.

The result is a door that provides certified protection while still fitting naturally into the overall building design.

Why Choose Premier SSL

Premier SSL specialises in the design, manufacture and installation of high security entrance systems. Our LPS 1175 swinging security doors are engineered to meet the operational demands of real world environments where both security and reliability matter.

Every project is assessed individually so the door configuration, hardware and installation method align with the risk profile of the building.

Our systems can also integrate with wider security strategies that include LPS 2081 stealth protection and LPS 1673 blast resistant door systems where required.

FAQ’s

LPS 1175 is a recognised security standard developed by the Loss Prevention Certification Board (LPCB). It tests doors against forced entry using defined attack tools and timed testing procedures. An LPS 1175 certified swinging door has been independently assessed to ensure the entire door assembly, including the frame, hinges and locking system, can resist physical attack.

The appropriate security rating depends on the level of risk associated with the building. Many commercial premises specify SR2 or SR3 rated doors as a baseline level of protection. Higher ratings may be required for sensitive environments such as data centres, infrastructure sites or buildings storing valuable assets.

LPS 1175 swinging security doors are commonly used in locations where protection against forced entry is required but daily access must remain practical. Typical applications include commercial buildings, utility facilities, data centres, transport infrastructure, healthcare environments and secure service entrances.
