Engineered flared terminal end sections designed for high-containment Thrie-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 Thrie-Beam Fishtail End Terminals (also referred to as wing end sections or terminal flares) conforming strictly to international highway safety specifications (AASHTO M180 / ASTM A123 / EN 1317). Mounted at the leading and trailing ends of triple-corrugated Thrie-Beam Guardrails, the flared fishtail eliminates blunt spearhead edges, preventing vehicle impalement and providing continuous kinetic energy dissipation.
Precision cold-formed from high-tensile structural steel (SS355JR, Q355B, Q235B, ASTM A36), our fishtail end sections undergo 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, engineered to withstand extreme desert heat across Saudi Arabia and the UAE, as well as high-salinity coastal highways in Southeast Asia and South America.
