The double wave beam guardrail, sized at 4320×310×85 mm with thickness options of 2.5 mm, 3 mm, and 4 mm, is engineered for standard highway applications, offering reliable crash protection and easy installation. The three wave beam guardrail, measuring 4320×506×85 mm with 3 mm and 4 mm thicknesses, provides enhanced structural strength and impact resistance, ideal for heavy-duty sections such as bridges, ramps, and high-traffic highways.
BeiFang Group’s guardrails utilize high-quality Q235/Q345 steel, formed via precision cold-bending technology to ensure dimensional accuracy and mechanical performance. The three surface treatment processes are adopted to further enhance the durability of the products, with specific process characteristics as follows:
Hot-dip galvanizing: Forms a dense zinc layer, providing long-term rust protection in harsh environments.
Powder coating: Offers a smooth, colorful finish with excellent weather resistance and aesthetic appeal.
Epoxy zinc-based coating: A new eco-friendly technology combining anti-corrosion performance and low carbon emissions, suitable for green highway projects.
All products comply with national and international standards including JT/T 281 and AASHTO M180, and have passed rigorous crash tests. With advanced production lines and a professional R&D team, BeiFang Group is committed to providing high-quality, durable traffic safety solutions for global highway construction projects.
