High-containment bridge safety barrier engineered for overpasses, viaducts, and river-crossing structures. Fully compliant with AASHTO M180, ASTM A123, and EN 1317 (H2 / H4b) standards, preventing errant vehicle rollover and bridge deck breaching.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. designs and manufactures heavy-duty Galvanized Metal Bridge Crash Barriers. Designed specifically for elevated highways, bridges, flyovers, and mountainous viaducts, our bridge barrier systems utilize reinforced multi-beam configurations—such as Thrie-Beam Guardrails or double-stacked W-Beam Guardrails—mounted on robust flanged structural steel posts.
Engineered from high-yield structural steel (SS355JR, Q355B, Q235B, ASTM A36), our bridge crash barriers feature flange-welded base plates anchored directly to reinforced concrete decks. With hot-dip galvanizing up to 1100 g/m² (approx. 80µm to 160µm thickness), they offer 30+ years of maintenance-free service life against severe marine salt fog, high humidity, and extreme desert temperatures across the Middle East, Southeast Asia, and South America.
