Company Profile
Dachu Traffic Facilities (Tianjin) Co., Ltd. supplies highway safety hardware including guardrail beams (W-beam and thrie beam), posts, spacers, washers, bolts, nuts, and scaffolding. This breadth allows procurement teams to source multiple barrier components from one entity, reducing supply chain complexity. No factory certifications or production capacity data are listed in this product brief; request a supplier qualification pack before shortlisting.
Applications
European Union member states are tightening road restraint system specifications under EN 1317. The standard covers performance classes for containment, impact severity, and working width. Thrie beam guardrails appear in high-speed corridors where a deeper, three-wave profile offers a different containment envelope than two-wave W-beam sections. This product, a 3 mm galvanized thrie beam, is positioned for such projects, though the specific performance class must be confirmed with the supplier.
The shift from generic galvanized W-beam to thrie beam in certain corridors reflects a broader trend: road authorities are demanding more than just a barrier line; they want predictable crash performance, reduced maintenance, and compatibility with modern vehicle fleets. Thrie beam's three-wave geometry is not a universal replacement, but it offers specifiers an additional option when project constraints demand different deflection characteristics. Procurement teams should map the specific EN 1317 class required — N1, N2, H1, H2, etc. — against the supplier's certified products.
In practice, thrie beam guardrails are deployed on medians, bridge parapets, and work zone barriers. Their use is typically driven by traffic volume, heavy vehicle share, and available deflection space. The galvanized finish addresses corrosion concerns in humid or coastal environments, while custom zinc coating allows project-specific durability requirements. Sourcing teams evaluating EN 1317-compliant systems should ask for third-party crash test reports and installation manuals before committing to this SKU.
Product Description
The product name defines the core configuration: a 3 mm thick galvanized thrie beam highway guardrail per EN 1317, with customizable zinc coating. The thrie beam profile includes three corrugations, which increases section depth relative to a two-wave W-beam. The 3 mm steel thickness is a nominal value commonly used in guardrail manufacturing, but actual thickness tolerance must be verified. Galvanization provides barrier protection against atmospheric corrosion; the coating mass can be specified according to project needs.
Pricing is listed at US$ 900.00–1,100.00 per unit. Buyers should clarify what constitutes a unit: a single beam panel, a set length, or a packaged section. This information is not specified in the product listing. For comparison, use the following feature-versus-advantage bullets.
- Feature: Thrie beam (three-wave) cross-section — Advantage: Greater section depth than conventional W-beam for projects where a stiffer barrier face is preferred.
- Feature: 3 mm nominal steel thickness — Advantage: A baseline material thickness that aligns with many national guardrail specifications, subject to confirmation.
- Feature: Galvanized finish — Advantage: Corrosion resistance for extended service life; coating can be customized for aggressive environments.
- Feature: EN 1317 reference — Advantage: Signals alignment with European road restraint system standards, enabling use in EU-funded or regulated road projects, pending class documentation.
No dimensional drawings, weight, or packaging details are provided in this brief. Contact the supplier for a full technical datasheet.
OEM & Customization
The product name explicitly mentions "Zinc Coating Customized." This means buyers can specify galvanizing thickness or an alternative coating system after engineering review. In addition to coating, Dachu Traffic Facilities lists related components — posts, spacers, washers, bolts, and nuts — which suggests the potential for complete guardrail kits or OEM supply programs. Customization of beam length, hole patterns, and coating color may be available, but these options require direct negotiation.
For OEM procurement, define your target EN 1317 performance class, site conditions, and installation method. Share these with the supplier to confirm that the 3 mm thrie beam can be produced to your exact specification. Request samples or a first-article inspection for large-scale highway programs.
CTA
Shortlist this 3 mm galvanized thrie beam guardrail if your project requires an EN 1317-referenced, customizable zinc coating. Request a supplier-qualified datasheet, including steel grade, coating mass, and independent crash test results, before finalizing your specification. Engineering approval must be based on verified performance data, not marketing language.
Disclaimer
The product details presented here are limited to the information available in the public listing. Final engineering approval and procurement decisions must rely on supplier-confirmed specifications, third-party test reports, and applicable national regulations. Dachu Traffic Facilities (Tianjin) Co., Ltd. should provide all missing parameters — including galvanized coating thickness, beam dimensions, and EN 1317 performance class — before any purchase order is issued.
