As a manufacturer based in Hengshui, Hebei, with a 5,000–10,000 square meter production facility and a dedicated team of 51–100 employees, Anping Xinye Metal Wire Mesh Products Co., Ltd delivers reliable steel infrastructure components to buyers worldwide. The Roll-Formed Steel Municipal Guardrail Post (114mm diameter, 4.8mm wall thickness) is engineered for demanding roadside safety applications, offering excellent impact resistance and long service life. Each post is manufactured with precision roll-forming techniques, ensuring consistent dimensions and structural integrity for dependable performance in municipal and highway projects.
Our guardrail posts are crafted from high-quality steel coils, processed through continuous roll forming to achieve a uniform cylindrical profile. The result is a post that provides strong structural support for W-beam or thrie-beam guardrail systems. With a 114mm outer diameter and a 4.8mm wall thickness, this post balances strength with workability, making it suitable for a variety of installation methods including direct driving, concrete embedment, or bolt-down connection.
- Consistent quality: Roll-formed manufacturing ensures uniform roundness and wall thickness across every post length.
- High strength: Robust steel construction withstands vehicle impact and harsh weather conditions.
- Full documentation: Each shipment includes a mill test report, verifying the chemical and mechanical properties of the steel.
- Versatile mounting: Pre-punched holes or custom configurations are available to match your existing guardrail hardware.
- Length options: Standard lengths or cut-to-size per your drawings, with a typical range from 1.2m to 3.0m.
- Surface protection: Hot-dip galvanizing (optional) enhances corrosion resistance for coastal or humid environments.
