Road Safety Guardrail and Impact Attenuator for GCC Infrastructure
Errant vehicles striking fixed hazards, guardrail ends, and roadside infrastructure cause severe injuries and fatalities across highways and construction zones. A road safety guardrail and crash cushion system absorbs and redirects impact energy away from the hazard, reducing crash severity and protecting both vehicle occupants and roadside workers across permanent and temporary installations.
Ideal for highways, urban roads and construction sites, this road safety guardrail reduces impact severity with advanced MASH TL3 tested technology. Reliable protection for UAE and GCC traffic. We supply the full crash cushion barriers range including MASH TL3 impact attenuators, rolling barriers, motorcycle-friendly guardrails, flexible steel guardrails, and end terminal systems for permanent highway and temporary work zone applications.
At Dutco Tennant LLC, we source road barriers and civil infrastructure safety solutions from established international manufacturers for highway, urban road, and infrastructure projects across the UAE and GCC, covering all safety barrier requirements across the region's most demanding road safety applications.

Application Area
National Highways and Expressways
- Highway authorities use highway crash barrier and crash cushion systems to shield gore points, median ends, and fixed hazards across high-speed carriageways
- Rolling barrier median installations reduce severe injury outcomes from high-speed cross-median collisions on divided national highways
- Highway safety end terminals shield guardrail ends and transition points where head-on vehicle contact risk is highest
Urban Roads and Intersections
- Urban road authorities use plastic safety barriers and crash cushions to protect pedestrians, cyclists, and workers at intersections and roundabouts
- Plastic traffic barriers provide rapid deployment protection across urban road works without permanent installation or ground preparation
- Water-filled plastic road barriers suit temporary lane closures and event traffic management across urban environments
Construction and Work Zones
- Highway contractors use road safety attenuator plastic and steel crash cushions to protect workers at active construction site boundaries
- Truck-mounted attenuator configurations protect slow-moving maintenance vehicles operating on live carriageways during inspection and repair
- Safety barrier plastic and modular crash cushion systems allow rapid reconfiguration as construction zone boundaries change during project progression
Bridge and Elevated Structures

FAQ
Where are crash cushion barriers typically installed on roads?
Crash cushion barriers are installed at high-risk locations such as median ends, exit ramps, toll areas, and fixed obstacles where vehicle impact needs to be controlled.
How does a crash cushion system improve safety on highways?
A crash cushion system absorbs and dissipates impact energy, reducing collision severity and helping protect vehicle occupants in high-speed environments.
What is the role of a highway crash barrier in road infrastructure?
A highway crash barrier helps contain and redirect vehicles, preventing them from leaving the roadway or colliding with hazardous roadside structures.
Are plastic safety barriers suitable for temporary traffic control?
Yes. Plastic safety barriers are lightweight, easy to install, and widely used for temporary applications such as roadworks, diversions, and event traffic management.
What is the importance of guardrail end treatment in safety systems?
Guardrail end treatment is essential to prevent vehicle snagging or abrupt stops at barrier ends, reducing the risk of severe impact injuries.
Where are rolling barrier systems most effective?
A rolling barrier system is particularly effective on curved roads, medians, and accident-prone zones where controlled redirection and impact energy management are critical.
