GS2 GS4 W Beam Guardrail System

This document introduces the GS2/GS4 W Beam Guardrail System, a core semi-rigid road safety facility. Originating in France and widely used globally, GS4 differs from GS2 only in post spacing. Composed of C posts, box spacers and W beams, all components share the same material and anti-corrosion treatment, forming an integrated rigid-flexible protective system via welding-free bolt assembly. Its specifications are adjustable and it suits various installation methods. Compared with traditional guardrails, the system features superior protective performance, easy installation and maintenance, and wide adaptability.

AASHTO Standards: The Definitive Code for U.S. Highway Engineering

This document analyzes the core AASHTO standards for U.S. highway engineering, the universal norms for American highway construction, covering all highway fields and adhering to the principles of safety, functionality and suitability. It features strong field applicability and rigorous quantitative technical requirements, specifying various indicators for components such as guardrails, integrating mainstream standards and balancing local and international units. The standards adopt a balanced quality control approach, embed life-cycle management, evolve with the industry, and their core concepts serve as an important reference for global highway engineering.

EN 1317 European Standard: The Core Certification Criterion for European Road Safety Barrier Systems

This document analyzes the EU's EN 1317, the core certification standard for road barriers, introducing its performance grading system centered on containment level, working width and impact severity as well as strict certification requirements, with a digital passport system added by the 2025 new EU regulation. It presents Safebuild's design drawings of various barrier products meeting different grades of the standard, compares EN 1317 with the US AASHTO MASH standard, and points out that EN 1317 has become a universal technical reference for global road barriers.

AASHTO MASH TL4 Passed-Roller Barrier (100km/h)

This document introduces that the roller barrier of Shandong Safebuild Traffic Facilities is the only domestic product passing the AASHTO MASH TL4 crash test. It explains its core principle of absorbing energy and guiding vehicles via rolling friction, presents its six core features, and also shows design drawings and lists specifications of 10 customizable rolling barrel accessories.

Interpretation of the EN1317 Standard for Highway Guardrails

Impact Performance Evaluation of Ezy-Guard High Speed Guardrail System

The performance of untested steel guardrail systems has been observed and commented on by experts in the field of the Middle East, with common observations showing that impacting vehicles have "splintered" W Beam Guardrails. This risk can be mitigated by using a system that has been tested to the standard (US NCHRP350 or MASH) such as Ezy-Guard.

The Historical Evolution of Chinese Highway Guardrail Standards

In order to improve road safety, Chinese highway guardrail standards are constantly improving. This paper will briefly introduce the evolution of Chinese highway guardrail from the surface treatment of waveform guardrail and the standard specification from two angles.

The Significance of The New Rolling Barrier System for Life Safety

Studies have shown that approximately 1.25 million people die in road accidents each year. Any research that can be used to reduce this number would be a welcome move. In many cases, vehicles hit guardrails on the side of the road, and this impact can cause greater injuries. Originating in South Korea, rolling barrier technology was created, a rotating guardrail technology that will increase the likelihood of saving lives.
