Choosing the Right Road Safety Barrier for Your Project: A Complete Guide
When it comes to traffic management and worksite safety, selecting the appropriate road safety barrier can make all the difference. At RPM Hire, we understand that every project has unique requirements, which is why we offer a comprehensive range of safety barriers designed to meet diverse needs across construction sites, roadworks, and special events.
Understanding Your Barrier Options
Road safety barriers come in various materials, deflection ratings and configurations; each suited to specific applications. The key is matching the right barrier to your project’s speed rating, installation requirements, and site conditions.


Water-Filled Barriers: Perfect for Events
Our ArmorZone Water-Filled Barriers are the ideal choice for events and temporary installations. Constructed from high-density polyethylene, these barriers are lightweight when empty at just 28kg per metre, making them easy to transport and position. Once filled, they provide protection with a speed rating of 70km/h and MASH TL-1 and TL-2 ratings, they’re perfect for controlled environments where quick installation and removal are priorities. A team of four can install an impressive 400 metres per hour, making them highly efficient for time-sensitive projects.

Concrete Barriers: Maximum Protection
When your project demands the highest level of protection, concrete barriers provide unmatched security. We offer both J-J Hook and DB80 K150 concrete barriers, both rated for 100km/h and MASH TL-3 compliant. These robust solutions are suitable for all uses and provide reliable, long-term protection for high-risk work sites.
Steel Barriers: The Construction Workhorse
For roadworks and construction sites requiring higher speed ratings, our HighwayGuard Steel Safety Barriers deliver exceptional performance. Rated for speeds from 90-100km/h (depending on vehicle) and meeting MASH TL-3 and TL-4 standards, these barriers offer a minimal deflection of 0.025m (MASH TL-3) at maximum impact speed. Their 6-metre sections allow for efficient coverage, with approximately 48 metres fitting per semi-trailer stack (or 144 metres when triple-stacked).
Making the Right Choice For Your Project
Several factors should guide your barrier selection. Consider the maximum speed rating required for your location, the available space for deflection upon impact, installation timeline and crew size, reusability needs across multiple sites, and compatibility with end treatments like QuadGuard, Absorb M, or Smart Crash Cushions.
