In mid-2026, Shandong Sino Guardrail Traffic Facilities Co., Ltd. successfully dispatched a bulk order of high-grade W Beam Galvanized Guardrail and Thrie Beam Guardrail systems directly to our client in Singapore. The shipment is destined for an expressway widening and roadside crash mitigation project, adhering to rigorous international highway safety criteria.

Due to Singapore's high traffic density and humid tropical marine climate, the local Land Transport Authority and civil engineering contractors require road crash barriers with extreme impact deflection capabilities and superior corrosion resistance. For this project, standard crash protection was reinforced with heavy-duty W beam galvanized guardrail on standard highway corridors, and multi-wave thrie beam guardrail at high-risk transition zones and bridge approaches.
All delivered safety barrier elements comply strictly with AASHTO M180 Class A / Class B standards and international quality certifications (CE, ISO 9001, SGS, BV). Below is the confirmed shipment configuration:
| Product Item | Dimensions / Model | Steel Grade | Zinc Coating |
|---|---|---|---|
| W Beam Galvanized Guardrail | 4320 × 310 × 82 × 3.0 / 4.0 mm | Q235B / Q355B (SS355JR) | Hot Dip Galvanized (550 - 1100 g/m²) |
| Thrie Beam Guardrail | 4320 × 506 × 83 × 3.0 / 4.0 mm | Q355B (SS355JR) | Hot Dip Galvanized (≥ 600 g/m²) |
| Guardrail Posts (H Post / C Post / Sigma Post) | Custom lengths (1800mm - 2150mm) | ASTM A36 / Q235B | Hot Dip Galvanized (≥ 600 g/m²) |
| Guardrail Accessories | Spacers, M16 Bolts & Nuts, Washers, Terminal Ends | Grade 4.8 / 8.8 High Strength | Hot Dip Galvanized Anti-Rust Finish |
As an industry-leading manufacturer with over 25 years of production and export experience, we applied our 15-step Quality Control (QC) workflow prior to loading:
Raw Material Verification: Checking steel coil chemical composition and tensile strength.
Precision Roll-Forming: Ensuring consistent wave curvature and accurate hole punching to eliminate on-site installation misalignment.
Galvanizing Thickness Measurement: Utilizing magnetic thickness gauges to guarantee zinc uniformity, preventing premature coastal corrosion.
Trial Assembly Testing: Pre-assembling sample beams, H posts, spacers, and fasteners to verify 100% fitting accuracy.
To avoid transit damage and white rust during ocean freight from Qingdao Port to Singapore Port, all W beam galvanized guardrails and thrie beam guardrail panels were bundled with heavy-duty steel strapping, wood cushioning between layers, and moisture-proof plastic wrap. Fasteners and small hardware were packaged in export-standard seaworthy wooden boxes with palletized support for rapid forklift unloading.
