Engineered for coastal high-corrosion environments, this duplex steel guardrail uses 2205 duplex stainless steel material, which offers 5 times higher corrosion resistance than ordinary galvanized guardrails. Passing the 1000-hour salt spray test without red rust, it can withstand long-term erosion from seawater, salt fog, and high humidity. With a 3.2mm thick structure and H4+ impact resistance grade, it can withstand collisions from 12-ton vehicles traveling at 100km/h, fully meeting the safety needs of coastal highways. Its 10-year maintenance cycle eliminates the need for coating replacement, significantly reducing long-term costs. Certified by ASTM and ISO standards, it is an ideal choice for coastal roads, port access roads, and island highways where corrosion resistance and durability are critical.
