A W-Beam guardrail is a two-wave corrugated steel rail supplied for roadside and median barrier projects. Configure it by the required profile, length, thickness, steel grade, coating, hole pattern and matching posts, spacers, terminals and fasteners. Send the approved drawing and BOQ so the supplier can confirm compatibility, production scope and quotation details.
Conclusion: Purchase the W-Beam configuration specified by the approved project drawing and BOQ.
Applicable conditions: Rail dimensions, steel, coating and components depend on the contract, site environment and authority requirements.
Evidence: Compare the drawing, material records, coating requirement, component schedule and inspection scope before production.
Exception: A similar-looking rail or a catalog dimension is not a substitute for the approved complete barrier configuration.
Hot-dip galvanized corrugated steel guardrail beams with Q235B or Q345B material options, project-specific lengths and thicknesses, and AASHTO M180 reference configurations. Final production is based on the approved drawing, bill of quantities and purchase specification.
Sinoguardrail supplies custom W-beam guardrails for roadside and median barrier projects. The beam is roll-formed from structural steel and can be supplied with a hot-dip galvanized or powder-coated finish according to the confirmed project specification.
Available material options for this product include Q235B and Q345B steel. The general base-metal thickness range is 2.5–4.0 mm, while the AASHTO M180 reference configurations below use a nominal uncoated thickness of 2.67 mm. These values are kept separate because they describe different ordering conditions and must not be treated as one fixed model.
| Parameter | Available or Reference Specification |
|---|---|
| Product profile | W-beam corrugated steel highway guardrail |
| Material options | Q235B or Q345B; the final material grade must be stated in the approved order |
| General thickness range | 2.5–4.0 mm base metal, customized by project |
| Reference standard | AASHTO M180 configuration available; final compliance scope is defined by the contract and inspection documents |
| Surface treatment | Hot-dip galvanized or powder coated |
| Zinc-coating mass options | 550 g/m² or 1100 g/m²; specify the required coating mass in the RFQ and purchase order |
| Galvanizing sequence | Galvanizing before or after fabrication can be discussed according to the project specification |
| Color | Customized when a powder-coated finish is required |
| Length | Reference AASHTO dimensions are shown below; custom length is subject to drawing approval |
| Application | Roadside and median highway barrier systems |
| Configuration | Overall Length | Effective Length | Nominal Uncoated Thickness |
|---|---|---|---|
| Type I | 4130 mm | 3810 mm | 2.67 mm |
| Type II | 4320 mm | 4000 mm | 2.67 mm |
Review the dedicated hot-dip galvanized W-beam guardrail page when corrosion protection is the primary project requirement.
See the Q235B and Q345B W-beam guardrail option for material-focused RFQs and mill-certificate requirements.
Use the AASHTO M180 W-beam guardrail page when the tender documents explicitly call for that standard.
For a broader comparison of thicknesses, gauges and purchasing considerations, read the W-beam guardrail dimensions and specification guide.
A beam alone does not define a complete roadside barrier system. Include the required posts, spacers, fasteners, terminals and transition details in the RFQ so every component can be checked against the same project drawing.
A correct W-beam quotation starts with the complete approved barrier arrangement, not the rail panel alone. Review the resources below before confirming your bill of quantities or replacement list.
Use our Highway Guardrail Components and BOQ Checklist to verify rails, posts, spacers, bolts, terminals and transition items before sending an RFQ.
Compare H, Sigma, U, C and round profiles in the Highway Guardrail Post Types Guide, then match the selected post to its rail, spacer and approved ground connection detail.
For replacement work after an impact, follow the Highway Guardrail Maintenance and Repair Guide and inspect adjacent connections before ordering parts.
Applicable standard and the latest project drawing
Overall length, effective length and required quantity
Base-metal thickness, tolerance and material grade
Zinc-coating mass or other required surface treatment
Hole pattern, splice direction and any curved-beam requirements
Post type, spacer type, bolts, terminals and transition sections
Inspection documents, marking, packing and destination port
State the required documentation in the RFQ before production. Depending on the contract, the inspection scope may include material certificates, dimensional inspection, hole-position checks, coating verification, bundle marking, packing lists and third-party inspection arrangements. Acceptance criteria should follow the signed specification rather than general website text.
Yes. Length and thickness can be customized within the available manufacturing range. Production dimensions still need to be confirmed through the approved drawing and order specification.
Both are available coating-mass options. The RFQ must identify which value applies; neither option should be treated as the automatic default for every project.
No. System behavior depends on the full configuration, including posts, spacers, fasteners, terminals, transitions, installation details and site conditions. Follow the project engineer's approved system design.
Send the target country, applicable standard, drawings, bill of quantities, material grade, thickness, coating requirement, component list, destination port and required delivery schedule.
Send your drawing and BOQ for review. The quotation can then identify the selected beam configuration, material, thickness, coating, matching components, packing and shipping terms.
