Hot Dip Galvanized Q235 Steel Two Wave Guardrail AASHTO M180 Road Safety Guardrail
Two Wave Guardrail, also known as Double Wave W Beam Guardrail, is a semi-rigid traffic safety barrier widely used for highways, roads, bridges, ramps, parking lots and scenic areas. It is composed of corrugated steel guardrail plates, columns, spacers, blocks and fasteners, which can effectively absorb collision energy, guide vehicles back to normal driving direction, reduce accident losses and protect pedestrians and vehicles.
Our two wave guardrail is made of high-quality Q235 / Q345 low-carbon steel, formed by automatic cold bending and rolling, with stable structure and high strength. The surface adopts hot-dip galvanizing or galvanized + powder coating treatment, with strong corrosion resistance, anti-aging, sun resistance and long service life, suitable for long-term use in outdoor harsh environments.
It has the advantages of easy installation, convenient replacement, good adaptability to terrain, beautiful appearance and coordinated with road alignment. It can be widely used in small radius curves, slopes, mountain roads and other complex sections, and is an ideal choice for road traffic safety protection.
