Guardrail post, as a holder of highway guardrails, generally determines the barrier’s performance during collisions. The guardrail posts we supply are well designed and made of high quality steel, such as Q235, Q345 and Q255 or depend on your needs. Additionally, it features a long service life due to its anti-rust and corrosion resistant characters, which proceed from its superior zinc coating or PVC coating

According to the place of your intended application, we provide guardrail posts with or without flange plates. Generally, the post without flange plate is mostly fixed to soft soil by post anchors. But if you want to fix it on the concrete road, the post with plate is your best choice for easy installation: Just fasten the post to your desired place with bolts.

Different shapes of guardrail posts we can supply:

Galvanized guardrail post                 PVC coated guardrail post.
