This guardrail offers high value for its price, addressing rural road safety pain points. Made from Q235 carbon steel, it meets AASHTO M180 Level 1 crash standards, withstanding a 2-ton vehicle colliding at 40km/h to prevent vehicles from running off roads into ditches or farmland. The hot-dip galvanizing process with a coating thickness of ≥60μm provides salt spray test resistance of ≥600 hours, ensuring no rusting for 15 years in rural open-air environments. The simplified wave structure reduces material usage, making the product 30% cheaper than standard guardrails without compromising safety. Its modular bolted design has simple installation steps, requiring no large equipment, improving construction efficiency by 30% and enabling local rural teams to operate independently. Widened column bases enhance stability on soft rural soil, and customizable lengths and colors cater to personalized rural road needs.
Technical parameters are optimized for rural road conditions: W-beam dimensions are 4000mm (length) × 310mm (width) × 750mm (height) with a 3.0mm thickness; columns are 114mm (diameter) × 4.0mm (wall thickness) × 2000mm (total height), requiring a 550mm burial depth. Connection bolts are M16×40 galvanized fasteners. The Q235 steel has a yield strength of ≥235MPa and tensile strength of 375-460MPa. In crash tests, it limits maximum deformation to ≤1000mm when hit by a 2-ton vehicle at 40km/h. The hot-dip galvanizing process ensures salt spray resistance of ≥600 hours without red rust. The standard color is silver gray, with optional traffic yellow customization. Installation spacing is 4000mm for straight sections, adjustable to 2000mm for curved roads. The total weight per meter, including columns, is approximately 48kg.
This guardrail is primarily used in rural highways, county roads, village roads, scenic area branch lines, farmland roads, and cliff-side rural roads. In mountainous rural areas, it prevents vehicles from falling off cliffs or into valleys; in plain rural areas, it avoids intrusion into farmland and reduces crop loss. It is also suitable for rural school zones and village entrances to protect pedestrian safety. For rural roads with soft soil, widened column bases improve stability; in rainy rural areas, hot-dip galvanizing resists rainwater erosion. As a core product for rural road safety poverty alleviation projects, it effectively enhances rural road safety levels with minimal investment, reducing accident rates and property losses in rural areas.
