A steel beam guardrail is a formed steel roadside barrier component supplied in W-Beam or Thrie-Beam profiles. Select it by the required material grade, rail geometry, thickness, coating, hole pattern and complete system drawing. Before ordering, confirm posts, spacers, fasteners, terminals, inspection records, quantities and destination requirements against the project BOQ.
Conclusion: Select the steel beam profile and material configuration specified by the approved project drawing.
Applicable conditions: Grade, thickness, coating, dimensions and matching parts depend on the contract, site environment and authority requirements.
Evidence: Verify the drawing, BOQ, material certificate scope, coating records, dimensional checks and complete component schedule.
Exception: A material grade or coating value that appears suitable does not approve a different rail profile or untested complete system.
Available with material, geometry and coating requirements defined by the project specification. Confirm the complete barrier-system documentation separately from the steel beam material specification.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. supplies Q235B and Q345B steel beam guardrails in W-Beam and Thrie-Beam profiles for drawing-based procurement. Material grade, rail geometry, thickness, coating and hole pattern must be confirmed against the project documents before production.
These components can be configured for roadside, median, bridge-approach and other barrier applications when the approved system drawing defines the required arrangement. Complete-system suitability depends on posts, spacers, fasteners, terminals, transitions, installation and site conditions.
| Parameter | Technical Specification |
|---|---|
| Material Grade | Q235B or Q345B. Confirm the required grade and mechanical-property requirements in the project documents; cross-standard equivalence requires approval. |
| Profile Types | W-Beam Guardrail (2-Wave) | Thrie-Beam Guardrail (3-Wave) |
| Standard Dimensions | Reference dimensions may be available for W-Beam and Thrie-Beam profiles. Confirm total and effective length, width, depth, hole pattern and tolerances from the approved drawing. |
| Steel Thickness | 2.5 mm to 4.0 mm product range references; specify nominal base-metal thickness and tolerance in the approved order. |
| Surface Treatment | Hot-Dip Galvanizing (HDG) / Electrostatic Powder Coating (Green, Blue, White, etc.) |
| Zinc Coating Mass | Product records may list 550 g/m2 or 1100 g/m2 options. Confirm the governing coating document, measurement basis, inspection method and acceptance criteria. |
| Applicable Standards | Use only the standards named in the contract. Material and coating documents do not replace complete barrier-system performance documentation. |
| Matching Posts & Spacers | H-Post (W150 x 13.5), C-Post, Sigma Post, U-Post, Round Post (114 / 140 mm) |
Use the approved engineering drawing and BOQ to confirm the complete guardrail component schedule:
Heavy-duty posts designed for ground embedded or base plate installation.
Full set of high-strength fasteners with anti-rust treatment.
High-containment barriers for high-risk crash zones & bridges.
Drawing and BOQ review: Confirm rail profile, dimensions, hole pattern, post spacing, terminals, transitions and quantities before production.
Material and coating records: Agree the required grade, thickness, coating basis, test method, lot traceability and inspection records in the purchase specification.
Complete-system documentation: Keep material, galvanizing and any project-required system-performance documents distinct and tied to the approved configuration.
Inspection and packing scope: Confirm marking, packing, destination, delivery terms and inspection points before production release.
Send the approved drawing, BOQ, material grade, thickness, coating requirement, inspection scope and destination for a project-specific quotation.
