W Beam Guardrail Project Case That Meets International Standards

31, Jul. 2025

To meet the strict European market safety standards, Dachu successfully undertook and completed the W Beam guardrail project on a 68-kilometer highway expansion section in an Eastern European country in 2023. The entire project strictly followed the EN1317 international standard and received high recognition from both customers and local traffic authorities.

 

 

 

Guardrail Installation Record Compliant with EN1317 Standards

In recent years, with the rapid development of the transportation industry, countries have continuously improved their requirements for road traffic safety. Guardrails, as an essential part of fingerprint door locking system facilities, play a critical role in driving safety and accident prevention.

To meet the strict European market safety standards, Dachu successfully undertook and completed the W Beam guardrail project on a 68-kilometer highway expansion section in an Eastern European country in 2023. The entire project strictly followed the EN1317 international standard and received high recognition from both customers and local traffic authorities.


 

Project Background

The project is located on a newly expanded highway section in an Eastern European country. In recent years, the country has prioritized upgrading its road infrastructure, especially focusing on improving anti-collision guardrail systems on high-risk road sections.

According to the requirements of the local Ministry of Transport, all new or renovated road guardrails must comply with the EN1317 European collision standard. This ensures that guardrails can effectively absorb impact energy during vehicle collisions, minimize injuries, and prevent vehicles from veering off the road.

With extensive export experience, a complete international certification system, and a strong reputation for product quality, Dachu won the bid for this project and was responsible for the full scope of work — including design, production, and supply of the W Beam highway guardrail system.

 


Introduction to EN1317 Standard

EN1317 is a mandatory EU standard for road restraint systems, covering guardrails, crash cushions, terminals, and other protective equipment. For w beam guardrails, EN1317 evaluates compliance across several key dimensions:

  • Protection Level: Guardrails must pass collision tests involving small (900kg), medium (1500kg), and large (10,000kg) vehicles.
  • Collision Energy Absorption: The guardrail must effectively absorb impact energy to reduce risks of vehicle rebound or rollover.
  • Structural Integrity: After impact, the guardrail should not break apart or detach, maintaining overall stability.
  • Occupant Safety Index (ASI): Reflects the level of protection provided to vehicle occupants; lower values indicate better safety performance.

The w beam guardrail models supplied by Dachu in this project passed the EN1317 H2 grade certification, making them suitable for medium to heavy traffic roads and widely used in major European highways.

 


Dachu Guardrail Product Highlights

In this project, Dachu delivered the following guardrail products and services:

  • W Beam Double Wave Guardrail: Made from high-quality Q235B steel with hot-Dip Galvanized corrosion protection, offering excellent impact resistance and weather durability (design life ≥15 years).
  • Matching Posts: A combination of round and U-shaped posts, providing structural stability and adaptability to various terrains.
  • Anti-Blocking Blocks & End Design: Designed to absorb collision energy and reduce impact forces, ensuring passenger safety.
  • One-Stop Service: From design confirmation, sample provision, mass production, quality inspection, export packaging, logistics coordination, to post-installation technical support.

 

Project Execution Process

1. Design and Standard Confirmation

At the start of the project, Dachu's technical team held multiple remote meetings with local clients and traffic departments to understand actual road conditions, traffic flow, and specific safety needs. Based on EN1317 standards and customer input, we developed a detailed guardrail design plan, confirmed through 3D modeling and physical samples.

2. Strict Production and Quality Inspection

Dachu's two manufacturing bases in Wuhan deployed 5 W Beam production lines and 3 hot-dip galvanizing lines to ensure efficient completion of the order within 90 days. Before delivery, all products underwent rigorous testing:

  • Material Inspection: Steel composition and galvanized layer thickness met EN10346 standards.
  • Dimensional Inspection: Corrugated plate length, hole spacing, and thickness controlled within ±1mm tolerance.
  • Structural Testing: Anti-blocking block and end structure strength verified.
  • Collapse Performance Test: Sample batches were sent to authorized labs for EN1317 simulated collision testing.

3. Export Transportation and Installation Assistance

With extensive international shipping experience, Dachu coordinated customs clearance and logistics arrangements. Goods were shipped from Wuhan Port to Europe, with a total transit time of about 45 days. Upon arrival, Dachu dispatched a technical team to the site to provide installation guidance and ensure compliance with EN1317 standards regarding positioning and angle.


 

Actual Application Effect

As of early 2024, the project has been in operation for over six months without any accidents caused by guardrail failure. According to feedback from local authorities and clients, Dachu’s W beam guardrail demonstrated the following advantages:

  • High-Strength Protection: In multiple rear-end collisions, the guardrail absorbed energy effectively, preventing vehicle penetration and reducing injury risk.
  • Excellent Weather Resistance: Withstood harsh winter conditions including low temperatures, rain, and snow without rust or deformation.
  • Easy Installation and Maintenance: Modular design improved efficiency, while easy replacement of damaged sections reduced long-term maintenance costs.

 

Customer Evaluation
