W-Beam Guardrail
W-Beam Guardrail
Our Custom W-Beam Guardrail is designed for contractors, infrastructure developers, road-safety distributors, EPC companies and government project suppliers that need more than a standard off-the-shelf barrier. The key purchasing question is not simply whether a W-beam highway guardrail is available, but whether the beam profile, steel thickness, hole pattern, coating, posts, accessories and packing can be matched to the project drawings, local standard and installation conditions.
As an integrated manufacturer and exporter with more than 10 years of international trade experience, we support both standard supply and project-based customization. Buyers can source guardrail beams together with compatible posts, spacer blocks, bolts, nuts, fasteners, end terminals and transition components, reducing the risk of receiving parts that do not match on site.
| Item | Specification |
|---|---|
| Product type | W-beam (two-wave) highway guardrail |
| Base material | Q235B / Q345B structural steel |
| Panel length | 4,320 mm (effective overlap length 3,810 mm); 4,000 mm EN-length also available |
| Wave width x height | 310 mm x 85 mm |
| Plate thickness | 2.5 mm – 4.0 mm (approx. 12–10 gauge) |
| Surface treatment | Hot-dip galvanized, 550–600 g/m² standard, up to 1,200 g/m² for coastal / high-corrosion sites; galvanized + powder coating optional |
| Post types | C-post, U-post, Sigma post, or box-section post to match your road design manual |
| Spacer / block-out | C-block, Sigma spacer, or timber block-out |
| Reference standards | AASHTO M180, EN 1317, GB/T 31439, and regional road-authority specifications |
| Containment level | NC-2 / NC-3 / NC-4 depending on post spacing and beam configuration |
| Tolerance | Dimensional tolerance controlled to keep bolt-hole alignment consistent across mixed-batch installation |
Standard dimensions cover the majority of highway and rural-road projects, but very few real projects use only "standard" parts — curves, bridge transitions and local design manuals almost always call for at least one adjustment.
A Custom W-Beam Guardrail should be specified around the actual road project rather than selected only by unit price. We can review project drawings and procurement specifications to confirm:
Beam length and effective installation length
Steel gauge or thickness
Hole pattern and connection requirements
Zinc coating requirement
Surface finish and project color
Straight or curved beam configuration
Post type and post spacing
Spacer or block-out configuration
Matching bolts, nuts and fasteners
End terminal and transition component requirements
Wooden or steel pallet packaging
Packing method based on container loading, unloading and site handling
For international tenders, please send the required standard, drawing, bill of quantities and coating requirement before quotation. This helps prevent dimensional mismatch, incompatible accessories and unnecessary rework after delivery.
The correct galvanized highway guardrail configuration depends on where and how the barrier will be installed.
Choose the beam, post system and spacing according to the approved road restraint design. Confirm the required steel thickness, zinc coating and terminal configuration before ordering.
Check the installation layout, available working width, post arrangement and connection details. The complete highway safety barrier system should be quoted as one coordinated package whenever possible.
Provide road geometry and drawings. Curved beam sections, transitions and connection details should be confirmed before production rather than adjusted on site.
Give the supplier the exposure conditions and required corrosion-protection specification. Zinc coating should be selected by project requirement and expected service environment, not only by the lowest initial cost.
Provide existing beam dimensions, hole spacing, post type and connection details. Photos and measured drawings are useful when matching an existing road restraint barrier.

We manufacture W beam guardrails according to:
AASHTO M180 (USA standard)
EN 1317 (European standard)
AS/NZS 3845 (Australia/New Zealand)
ISO 9001:2015 quality management
All products can be customized to meet specific project specifications and tender requirements.
W beam has a double-wave profile, while thrie beam has three waves and provides higher impact resistance.
It depends on your region:
USA → AASHTO M180
Europe → EN 1317
Others → project-specific standards
Common zinc coating ranges from 550 g/m² to 1100 g/m², depending on environmental conditions.
Yes, we provide all components including posts, spacers, and fasteners.
Guardrail beams are bundled and secured for ocean freight, with posts and hardware boxed separately to prevent damage in transit; pallet type (wood or steel) and bundle size are set to match container capacity and your unloading equipment on site. We work on EXW, FOB, CFR, CIF and DAP terms and can mix guardrail, posts and hardware in the same container to reduce your overall freight cost per project.
If you are sourcing reliable highway safety barriers for infrastructure projects, our W beam guardrail systems offer proven performance, standard compliance, and scalable supply capacity.
