Engineered flared terminal end sections designed for standard W-Beam Guardrails. Fully compliant with AASHTO M180 Class A/B, ASTM A123, and EN 1317 standards with heavy-duty 1100 g/m² zinc protection.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. manufactures heavy-duty W-Beam Fishtail End Terminals (also known as flared wing terminal sections) conforming strictly to international highway safety standards (AASHTO M180 / ASTM A123 / EN 1317). Positioned at the starting and trailing ends of corrugated W-Beam Guardrails, the flared curved geometry safely anchors the terminal run, eliminates blunt beam edges, and prevents errant vehicle impalement during head-on or shallow-angle impacts.
Precision cold-formed from high-tensile structural steel (SS355JR, Q235B, Q345B, ASTM A36), our W-beam fishtails are treated with heavy-duty hot-dip galvanizing from 550 g/m² to 1100 g/m² (approx. 80µm to 160µm thickness). This provides 30+ years of maintenance-free service life, built to withstand arid desert environments across Saudi Arabia and the UAE, as well as high-humidity coastal and tropical highways throughout Southeast Asia and South America.
