Heavy-duty structural W150 × 13.5 steel posts and blockouts designed for W-Beam and Thrie-Beam crash barriers. Fully compliant with AASHTO M180, ASTM A36 / A123, and EN 1317 standards.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. specializes in manufacturing high-strength Highway Guardrail H Posts (I-Beam / Wide Flange Posts) and matching H Spacers (Offset Blocks). As the structural foundation of roadside barrier systems, our H-posts are precision-cut and punched from high-quality structural steel (ASTM A36, Q235B, Q345B / SS355JR) to provide superior dynamic load resistance during vehicular impacts.
Every post undergoes an advanced hot-dip galvanizing process delivering heavy-duty zinc coating protection from 550 g/m² up to 1100 g/m² (80µm - 160µm). This ensures 30+ years of maintenance-free service life even in extreme desert climates across Saudi Arabia, UAE, and the harsh tropical conditions of Southeast Asia and South America.

Sinoguardrail manufactures a full spectrum of highway crash barrier posts and energy-absorbing systems to meet international tender standards:
An H post must be selected with its matching rail, spacer or blockout, hardware and approved ground connection. Use the following guides before confirming a project BOQ or a replacement order.
Read the Highway Guardrail Post Types Guide to compare H, Sigma, U, C and round posts by profile and approved connection arrangement.
Use the Highway Guardrail Components and BOQ Checklist to verify rails, spacers, bolts, washers, terminals and transition items before quotation.
For post replacement after an impact, follow the Highway Guardrail Maintenance and Repair Guide and inspect adjacent rails, connections and ground condition first.
