Description

When a collision occurs, something has to give. With standard rigid bollards, that “something” is often your expensive concrete foundation or the vehicle itself. Our Breakaway Double Flanged Bollards offer a smarter solution.

Engineered for high-risk environments, these posts feature a specialized Double-Flanged Base System designed to “yield” or detach upon significant impact. This sacrificial mechanism absorbs the energy of the collision, minimizing injury to vehicle occupants and—crucially—preventing the bollard from ripping up the concrete footing.

Standing at a substantial 1900mm height, they are perfect for high-speed zones, road edges, and industrial thoroughfares where visibility is paramount.

Preserves Your Foundations

The most costly part of a bollard collision isn’t replacing the post; it’s repairing the cracked concrete slab.

 

  • The Problem: Rigid bollards transfer force directly into the ground, often destroying the footing.

  • The Solution: The double-flanged design creates a weak point above the ground. Upon impact, the bollard shears away safely, leaving your foundation intact and saving you thousands in ground repairs.

Maximum Visibility & Signage Support

At 1.9 meters tall, these are among the most visible safety posts on the market.

 

  • Road Edge Safety: Ideal for highways and driveways where drivers need early visual warning.

  • Signage Ready: The extended height makes them the perfect structural support for mounting speed limits, stop signs, or directional signage directly onto the post.

Two Heavy-Duty Finishes

Select the finish that suits your environment:

 

  • Hot Dipped Galvanised: The industrial choice. A raw, metallurgical zinc bond that offers superior rust protection. ideal for harsh weather or coastal roads.

  • Safety Yellow Powder Coat: The high-visibility choice. Applied over a galvanised base for double protection, ensuring the bollard is easily seen day or night.

Ideal Applications

  • Road Edges & Highways: Reducing severity of accidents for stray vehicles.

  • Industrial Thoroughfares: Protecting walkways near heavy trucks where turning circles are tight.

  • Signage Mounting: Dual-purpose safety barrier and signpost.

  • Car Parks: Areas where minor bumps are frequent and floor damage must be avoided.

How does the breakaway mechanism work?

The bollard utilises a “Double Flange” system. The bottom flange bolts to the ground, and the top flange (attached to the post) bolts to the bottom one. The connection hardware is designed to be the “fuse” shearing or deforming under heavy load so the post falls over rather than tearing out of the concrete.

Can the bollard be re-used after impact?

It depends on the severity of the impact. In many cases, you simply need to replace the connecting bolts or the bollard itself, while the ground anchor and concrete remain undamaged. This is significantly cheaper than re-pouring concrete.

Why are they so tall (1900mm)?

The extra height provides visibility for heavy vehicles with high cabins and allows the bollard to double as a mounting post for traffic signage at eye level.
