6 Road Safety Barriers Types & When to Use Each One: A Practical Guide
Modern transport networks rely on carefully selected road safety barriers types to reduce impact severity, guide traffic, and protect people and assets. Selecting the correct barrier is a critical decision in roadside safety
planning for engineers, contractors, and road transport departments, as each design addresses a specific risk scenario and traffic environment.
At Armco Superlite, we are a leading importer, manufacturer, supplier, and distributor of premium-quality road safety equipment across southern Africa. With decades of experience and a portfolio specifically designed to align with international testing standards, we deliver compliant barriers, traffic guides, and other road safety equipment for highways, urban roads, heavy industry facilities, and construction zones, helping planning professionals meet performance and safety expectations.
Road Safety Barriers Types in Today’s Categories
Before selecting an entire system, it helps to investigate how road safety barriers types fit into broader barrier categories. Each option manages vehicle redirection, energy absorption, or impact termination differently. However, they all contribute to effective crash attenuation and long-term roadside safety. For example:
1. Steel Guardrail Systems:
Product: W-Beam Guardrails.
Steel guardrails are arguably the safest solution along highways, high-speed routes, and mountainous passes. Their corrugated steel profile redirects errant vehicles back toward the carriageway while absorbing kinetic energy, reducing the risk of rollovers, head-on crashes, and secondary collisions. These systems are frequently positioned along embankments, medians, and bridge approaches where controlled redirection is essential.
At Armco, we manufacture superior-quality steel W-beam guardrails available in both plain and galvanized steel. We can manufacture and deliver, including treated wooden posts conforming to SANS 457, or specialised steel posts manufactured to your requirements.
2. Waterfilled Safety Barriers:
Product: New Generation Waterfilled Safety Barriers.
Although not suitable for high-impact obstacles, these barriers offer a formidable boundary between traffic, workers, and equipment. They deliver rapid deployment and visible separation in temporary traffic management. Filled units absorb impact energy through controlled water displacement, making them ideal near roadworks, events, and lane closures. Available in various colours, their modular nature allows quick reconfiguration while maintaining roadside safety in changing conditions.
3. Wire Rope Safety Fences:
Product: Wire Rope Safety Fence.
Wire rope systems rely on high-tension cables mounted on steel posts. During a collision, the cables deflect and dissipate kinetic energy, providing effective crash attenuation with reduced vehicle damage. These barriers work particularly well along medians and thinner verges where controlled deflection space is limited.
4. The EuroNEAT™ Safety System:
Product: The EuroNEAT™ Impact Cushioning System.
Impact cushions mitigate hazards at fixed object sites, such as concrete barrier starting points, toll plazas, and structural ends. This system absorbs frontal impacts and reduces occupant deceleration, protecting drivers during head-on collisions with heavy, stationary objects by instantaneously inflating a self-contained, lifesaving cartridge. This solution is vital within modern, frequently moving roadside safety strategies. It is easy to install and meets EN 1317-3 criteria for non-re-directional crash cushions.
5. End Terminals:
Product: EuroET™ End Terminal.
End terminals prevent exposed guardrail ends from becoming rigid road hazards. The EuroET™ terminal dissipates energy during an impact by guiding the vehicle along a controlled path, reducing penetration risk. It integrates with steel guardrails to complete a safe and compliant installation.
6. More Lifesaving End Terminals:
Product: Trend CEN End Terminals.
The Trend CEN terminal meets stringent European safety standards, including the ENV-1317-4 criteria, and enhances safety at barrier terminations. Along with our wider W-beam and other barrier offerings, these solutions manage diverse traffic volumes, site constraints, and regulatory requirements across southern Africa. Their use strengthens network-wide safety planning and long-term asset performance.
