Heavy-duty turned-down end anchorage system engineered for highway crash barrier terminals. Compliant with AASHTO M180 Class A/B, ASTM A123, and EN 1317 standards, providing critical tensile anchoring and impact redirection.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. designs and manufactures high-tensile Steel Ground Anchor Highway Guardrail Systems (also referred to as buried-in-backslope anchorages or turned-down terminal anchors). Installed at the beginning and trailing ends of roadside barrier runs, the ground anchor system secures the corrugated steel beam into a solid foundation or soil slope, establishing essential tensile ribbon strength throughout the entire guardrail line.
Manufactured from premium structural steel grades (SS355JR, Q345B, Q235B, ASTM A36), our steel ground anchors ensure that oncoming vehicles striking the barrier downstream receive continuous redirection without rail detachment. Each assembly is fully treated with hot-dip galvanization up to 1100 g/m² (80µm - 160µm), preventing subsurface and atmospheric corrosion across the desert regions of Saudi Arabia and the UAE, as well as humid tropical highways in Southeast Asia and South America.
