The GB2 Barrier is a heavy-duty construction site barrier designed for highway and site delineation where both pedestrian and vehicle safety are required. With a 2-metre working length and 900mm height, it provides effective low-level perimeter demarcation across roadworks, site boundaries, and access control zones. The GB2 Barrier is MIRA wind speed tested to 78mph, making it a reliable choice for exposed highway sites and longer-duration deployments.
The pin locking device allows each barrier to be set at up to 35 degrees of angular adjustment, so the system follows curves, corners, and angled boundaries without the need for specialist configuration items. The fully stackable design simplifies transport and storage, and the standard red and white colouring ensures high visibility from approach.
For sites requiring greater height or security, anti-climb mesh and Hoarding Panels attach to the top of the GB2 to increase the overall barrier height. The system is suited to central reservation separation, footpath segregation, contractor access demarcation, and urban perimeter control.
Key Features and Benefits
MIRA wind speed tested to 78mph: Independently verified stability rating for exposed highway and site locations
2m working length, 900mm height: Effective coverage per unit reduces the total number of barriers required for long perimeter runs
35-degree pin locking configuration: Adapts to curves, corners, and angled site boundaries without specialist parts
Fully stackable: Reduces transport and storage costs with a compact, stable stacking profile
Mesh and hoard topping compatible: Accepts anti-climb mesh and hoarding panels to increase height and security at the perimeter
Red and white as standard: High-visibility colouring for compliance with site and highway visibility requirements
Frequently Asked Questions
Q. What makes the GB2 Barrier suitable for highway delineation?
A. The GB2 Barrier combines a 2-metre working length with a 900mm height and a MIRA wind speed rating of 78mph, giving it a higher wind resistance than many comparable low-level barriers. The pin locking system allows 35-degree angled configurations, which means the barrier follows the line of the road or carriageway without gaps or misalignment. These characteristics make it suitable for central reservation work, lane closures, and extended perimeter runs on exposed highway schemes.
Q. Can the GB2 Barrier be used for both pedestrian and vehicle management?
A. Yes. The GB2 Barrier is designed for dual use across Pedestrian And Vehicle Management on construction sites and highways. For pedestrian separation, the standard barrier height and high-visibility colouring provide clear demarcation. For sites requiring additional access control or anti-climb security, mesh and hoarding panels attach to the top of the barrier to increase the overall height. Pedestrian And Vehicle Gates are also available where controlled access points are needed within the barrier line.
Q. How does the pin locking system work on the GB2 Barrier?
A. The pin locking device on the GB2 Barrier allows each unit to be adjusted to up to 35 degrees relative to the adjacent barrier. You lock the pin at the required angle to hold the configuration in place without additional fixings. This makes the system adaptable to curved roads, angled site boundaries, and non-linear perimeters. The fully stackable design means the barriers transport and store efficiently between deployments.
