Next-generation safety rolling barrier certified under MASH TL4 / TA (100 km/h) standards. Converts hazardous linear collision momentum into smooth rotational kinetic energy, redirecting errant vehicles and preventing secondary crashes.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. is China's premier manufacturer holding authentic MASH TL4 (100 km/h) crash test reports. The New Type Trigard Rotor Roller Barrier is an advanced safety innovation engineered for severe collision-prone zones such as sharp highway bends, mountain cliff edges, bridge transitions, tunnel entries, and expressway split ramps.
Structured with continuous high-elasticity EVA/PE composite rotating barrels supported by high-strength tubular steel posts and longitudinal channels, the Trigard rotor barrier functions like an upright dynamic abacus:
Kinetic Energy Conversion: Activates rolling friction immediately upon impact, converting direct lateral impact shock into forward rotational energy.
Vehicle Redirection & Stability: Safely guides the vehicle along the travel direction without severe deflection, preventing vehicle spin-outs, rollovers, or vaulting over barriers.
Long-Term Durability: Combines UV-stabilized weather-resistant polymers with heavy-duty hot-dip galvanized steel frames (up to 1100 g/m²) for a 30+ year service life in extreme desert heat (Saudi Arabia, UAE) and humid tropical regions (Southeast Asia, South America).
