In 2025, the market size of China's 3D bent guardrail (also known as triangular bent guardrail mesh) segment has reached 4.87 billion yuan. It is expected to expand steadily at a compound annual growth rate (CAGR) of 11.3% from 2023 to 2030, with the market scale projected to break through the 8 billion yuan mark by then. Currently, the market presents a distinct pattern of "quality upgrading and replacement in the eastern region and incremental expansion in the central and western regions". Over 60% of the highway guardrails in the eastern region have been in service for more than 15 years, and the concentrated release of stock renewal demand has forced products to upgrade to protection standards above Grade S. Benefiting from the accelerated infrastructure construction during the 14th Five-Year Plan period, the upgrading of border security and the supporting construction of new energy bases, the incremental market in the central and western regions has achieved a growth rate as high as 14.2%, becoming a new engine for the industry's growth.

The advantage of life cycle cost (LCC) has further promoted market penetration. Although the initial purchase cost of 3D bent guardrails is 8%-10% higher than that of traditional products, relying on a 40% improvement in installation efficiency, a 31% reduction in maintenance costs and 100% recyclable property, their comprehensive cost over 30 years is 15% lower instead. Moreover, their carbon footprint is 42% less than that of traditional concrete fences, making them the preferred choice for government infrastructure projects.
