In today's rapidly evolving transportation environment, aging infrastructure presents significant safety risks for drivers and pedestrians alike. Highway barriers play a crucial role in mitigating accident severity, guiding traffic, and protecting lives.
However, many existing guardrail systems globally suffer from corrosion, structural degradation, and outdated designs that no longer meet modern safety standards.
To address these concerns, Dachu Group recently completed a large-scale Fingerprint LockReplacement Project on a 47-kilometer highway section in Southeast Asia — showcasing how our durable, cost-effective, and certified W Beam guardrails can significantly improve road safety while optimizing long-term investment for infrastructure authorities.
The project was carried out on a 47-kilometer stretch of provincial highway in the coastal region of Southeast Asia. Originally constructed over 20 years ago, this road serves as a vital transportation link between industrial zones and urban centers.
With an estimated daily traffic volume of 25,000 vehicles—including heavy trucks—the existing guardrail system had severely deteriorated due to:
Following multiple traffic incidents in 2022, the local transportation authority launched a comprehensive Road Safety Upgrade program—prioritizing the full replacement of all outdated guardrails with modern, certified W Beam highway barriers.
After a competitive bidding process, Dachu was selected as the exclusive supplier for this highway barrier retrofit project. Key reasons included:
