EnviroProtect® Anti-Climb SR1 (A1) LPS 1175 High Security Railings

EnviroProtect® Anti-Climb SR1 (A1) LPS 1175 Vertical Bar Railing Systems

The EnviroProtect® Anti-Climb Vertical Bar Railing Kit is a revolutionary perimeter security system. Designed for sites where an aesthetic appearance must be seamlessly blended with LPS 1175 certified protection.

This unique solution presents the clean, professional look of a traditional vertical bar railing to the public, while incorporating a covert, maximum-security layer of 358 "prison mesh" welded to the internal face. This ingenious design eliminates hand and footholds, making the railing virtually impossible to scale.

Fully certified to the stringent LPS 1175 SR1 (A1) standard, this system provides a formidable, dual-layered defence against both climbing and forced entry. This makes it the definitive choice for securing prestigious sites, government buildings, and critical infrastructure.

A Groundbreaking Dual-Layered Defence

The core innovation of the EnviroProtect® Anti-Climb railing lies in its unique dual-layered construction, combining strength, security, and visual appeal. On the exterior, 25.4mm vertical steel tubes are set at 100mm centres, delivering the classic look of a high-quality railing system while preserving an open feel and clear visibility for effective site surveillance. Hidden within this framework, however, is the true security enhancement: a full sheet of high-tensile 358 "prison mesh".

Designed for the most secure environments, this dense mesh, featuring 76.2mm x 12.7mm apertures, prevents any finger or toe holds, eliminating the common vulnerabilities of standard railings. Its 4mm wire gauge further resists cutting by conventional hand tools, ensuring uncompromising protection.

By intelligently fusing these two designs, the EnviroProtect® Anti-Climb railing achieves an elegant balance. This offers an aesthetically pleasing perimeter solution that doubles as an impenetrable barrier against even the most agile intruders.

LPS 1175 SR1 (A1) Certification

A visual deterrent is not enough for high-risk locations; security must be proven and certified. Every EnviroProtect® Anti-Climb Vertical Bar Railing Kit is tested as a complete system and is formally certified to the LPS 1175 A1(SR1) standard by the Loss Prevention Certification Board (LPCB).

This certification is a trusted benchmark for police, insurers, and security professionals across the UK. It provides verifiable proof that the entire railing assembly, including the vertical bars, horizontal rails, welded mesh, and their fixings, can withstand a sustained 60-second attack from an opportunist using a range of tools.

This critical delay is designed to frustrate an intruder's efforts, forcing them to abandon their attempt and providing your security team with vital time to respond to a breach.

Choosing this certified system ensures your perimeter defence is not just strong, but has been independently proven to be effective against a recognised threat level.

Engineered for Lasting Durability

The EnviroProtect® Anti-Climb system is engineered for exceptional longevity and resilience. All the components are made from pre-galvanised steel, which prevents rust and corrosion. This is a useful feature as it helps ensure a long life for your system and low maintenance expenses.

The EnviroProtect® Anti-Climb range is also available with a Polyester Powder Coated (PPC) in a choice of colours. This can add branding and style to your system by creating an easy-to-recognise perimeter. Choose from a range of RAL colours for your EnviroProtect® Anti-Climb system, including:

• Black
• Green
• Blue
• Red
• Yellow
• Grey

System Integration and Installation

We have designed a full security system, which is EnviroProtect® Anti-Climb approved and LPS 1175 certified.

These are available in both blot-don and dig-in configurations to suit the ground conditions.
