EnviroProtect® SR1 (A1) LPS 1175 High Security Railings

EnviroProtect® SR1 (A1) LPS 1175 Vertical Bar Railing Kits: High-Security Perimeter Solutions

Protect sites immediately from the perimeter by deterring intruders and stopping unauthorised access. The EnviroProtect® SR1 (A1) LPS 1175 Vertical Bar Railing Kits from First Fence offer a strong and reliable solution. They are suitable for many commercial, industrial, and institutional settings for full protection and flexibility.

Understanding LPS 1175 SR1 (A1) Certification

LPS 1175 is an internationally recognised standard for testing the strength of security barriers like fencing systems. This standard is set by the Loss Prevention Certification Board (LPCB), which is part of the Building Research Establishment (BRE). Fencing systems and gates require extensive testing to reach this certification.

The SR1 (A1) rating shows that the product can resist an attack for at least one minute. This attack uses basic hand tools like pliers, screwdrivers, or cable cutters. While one minute may sound brief, it is highly effective in practice.

This delay makes it harder for an intruder, and they often abandon their attempt to breach the railing. It also gives security teams or police important time to notice the attempt and respond.

The EnviroProtect® range fully meets this certification level, meaning experts have independently tested and verified its strength. With its clean vertical bar design, it delivers proven security without sacrificing a professional appearance.

A Range of Heights for Different Security Needs

The EnviroProtect® SR1 (A1) kits are available in four heights: 1.8m, 2.0m, 2.4m, and 3.0m. Each is designed to meet specific site requirements, to ensure top-notch security no matter where you need it.

1.8m High Kit

The 1.8m kit offers an excellent balance between visibility and deterrence. The kit creates a clear boundary while still allowing visibility through the bars. This railing is good for places like retail parks, businesses, and public areas where style and security are important. The vertical bars are 100mm apart. Manufacturers create them from 25.4mm thick pre-galvanised steel tubing. This design helps resist corrosion and physical damage.

2.0m High Kit

The 2.0m option provides an additional layer of deterrence with its extra height. It strengthens the barrier against intruders while maintaining clear visibility for monitoring and CCTV. This version is well-suited to office complexes, warehouses, and medium-security industrial sites. Like the 1.8m kit, it uses robust pre-galvanised construction with the same high-quality spacing and thickness.

2.4m High Kit

For higher-risk environments, the 2.4m railing kit offers stronger protection. Its added height creates a more challenging obstacle for potential intruders, while still maintaining sightlines for security teams. This makes it ideal for utilities, transport sites, and industrial facilities that house valuable equipment or assets.

3.0m High Kit

The tallest option in the range, the 3.0m railing kit provides maximum perimeter defence. Designed for critical infrastructure and high-security sites, it creates a formidable barrier that meets strict SR1 (A1) standards. Its pre-galvanised tubular steel design is made to handle tough conditions. It provides lasting performance and peace of mind.

Long-Lasting Construction and Protection

Every EnviroProtect® railing kit is built from pre-galvanised steel that complies with BS EN 10346 standards. This finish protects against corrosion and ensures the fencing can withstand long-term exposure to the elements.

The design features 25.4mm tubular steel bars spaced at 100mm centres. This provides excellent strength while maintaining visibility, making it compatible with CCTV and security patrols. The pre-galvanised finish also allows for additional treatments, including powder coating in corporate colours or standard finishes such as green and black. This flexibility means the fence can be tailored to match its surroundings or reinforce a professional brand identity.

Flexible Installation Options

The EnviroProtect® kits are designed to adapt to different site conditions with bolt-down and dig-in installation options.

• Bolt-down posts are perfect for solid surfaces such as concrete or paved areas, using ground anchors for a secure fit.
• Dig-in posts are set directly into concrete, providing enhanced strength on softer ground.

This flexibility allows users to install the system on flat, sloped, or uneven terrain without compromising its security performance.

Applications Across Multiple Sectors

The EnviroProtect® SR1 (A1) Vertical Bar Railing Kits are suitable for a wide variety of environments, including:

• Commercial and industrial estates
• Utilities and critical national infrastructure
• Transport hubs, airports, and logistics centres
• Schools, colleges, and universities
• Retail and business parks
• Any site requiring LPS 1175 SR1 (A1) certified protection
