Specify a hot-dipped galvanized W-Beam guardrail by separating the steel base-metal requirements from the zinc-coating requirement, then matching both to the approved barrier system drawing. Confirm the governing document, rail geometry, coating measurement basis, tolerance, posts, terminals, inspection method and complete component schedule before quotation or production.
Conclusion: Buy the hot-dipped galvanized W-Beam configuration required by the approved project documents, not a generic rail with a similar coating description.
Applicable conditions: Steel, coating, dimensions, components and test records depend on the governing standard, approved drawing, exposure environment and contract.
Evidence: Compare the drawing, BOQ, material records, galvanizing records, inspection method and component schedule before release.
Exception: A rail may meet a material or coating requirement yet still be unsuitable when the complete barrier-system configuration is not approved for the project.
Reference basis: AASHTO M180, corrugated sheet-steel guardrail beam specification. Confirm the applicable edition, coating document and complete-system requirements in the contract.
W-Beam rail and matching components can be quoted to the project drawing and named material or coating requirements. Confirm the complete barrier-system documentation separately from the rail material specification.
Shandong Sinoguardrail Traffic Facilities Co., Ltd. supplies hot-dipped galvanized W-Beam rails (two-wave corrugated profile) and matching components for drawing-based procurement. Steel grades, rail geometry, hole pattern and coating requirements must be stated in the project documents. A rail component alone does not establish the performance of a complete roadside barrier system.
Available product records list zinc-coating options of 550 g/m2 or 1100 g/m2. The required coating mass, measurement basis, inspection method and acceptance criteria must follow the contract and exposure environment. Do not convert a coating mass to an assumed thickness or service life unless the applicable project document defines that method.
| Parameter | Configuration to Confirm in Project Documents |
|---|---|
| Product Profile | Hot-dipped galvanized W-Beam (two-wave profile), subject to the approved drawing |
| Standard Dimensions | Confirm total and effective length, width, wave depth, thickness, hole pattern and tolerances from the approved drawing. Do not treat catalog dimensions as universal system dimensions. |
| Steel Material Grades | State the required grade and mechanical-property requirements in the contract. Do not assume grades from different standards are interchangeable without project approval. |
| 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 in the order. |
| Matching Post System | Confirm the specified post type, dimensions, spacing, embedment, coating and compatibility with the rail from the approved system drawing. |
| Matching Offset Block | Confirm spacer or blockout type, dimensions, hole locations and compatibility with the selected rail and post. |
| System Hardware | Confirm bolt type, diameter, length, strength grade, washer, coating and quantity from the approved component schedule. |
| Applicable Standards | Use only the documents named in the contract. Material and coating specifications do not replace complete barrier-system performance documentation. |
Use the approved drawing and bill of quantities (BOQ) to confirm the complete component schedule for the project:
Approved drawing and BOQ: Confirm rail profile, length, hole pattern, post spacing, terminal layout, transitions and quantities.
Material and coating records: State the steel grade, thickness, coating requirement, measurement basis, test method and lot traceability required by the contract.
Complete-system documentation: Keep material, galvanizing and any project-required system-performance documentation distinct, and verify the relevant scope for the approved configuration.
Inspection and packing scope: Agree inspection points, acceptance criteria, records, marking, packing, destination and delivery terms before production.
Send the approved drawing, BOQ, material and coating requirements, quantity, inspection scope and destination. We can review the requested rail and matching components before quotation.
