In highway guardrail systems, posts play a critical role in providing vertical support and load transfer. When a vehicle collides with a guardrail panel, the impact force is transmitted through the energy-absorbing block to the post, which then disperses and transfers the force into the foundation, ensuring that the entire guardrail system does not overturn or shift significantly.

Our company offers a wide range of post types, including C-type, U-type, Z-type, and H-type posts. All posts are manufactured and inspected in strict accordance with international standards. The post surfaces undergo hot-dip galvanizing treatment simultaneously with the guardrail panels, ensuring long-term rust resistance in various outdoor environments, including humid conditions and industrial pollution. The standard post spacing for guardrail sections is 4 meters. At critical locations such as sharp curves, accident-prone areas, or bridge approaches, the spacing can be reduced to 2 meters to enhance overall crash resistance. Post caps are typically installed at the top of the posts to prevent rainwater infiltration and corrosion. Our company can also customize non-standard posts (such as different diameters, wall thicknesses, or lengths) based on customer-provided drawings or on-site conditions, and provide matching energy-absorbing blocks and bolted connectors to ensure the integrity and reliability of the guardrail system.
