Guardrail Post Caps

guardrail post caps for sale

The guardrail post cap is also called rain-proof cap. It is an important part of the guardrail system. Without the post cap, the rainwater will be stored inside the post, and it is hard to evaporate. As there is acid material in the rainwater, the post will be corroded badly. As a result, the service life of the guardrail post will be shortened.

To improve the anti-corrosion performance, the surface of guardrail post caps are always treated by galvanization or galvanization + powder coating.

Regarding the sizes, RANHUA offers multiple choices. The guardrail post cap size is selected according to the size guardrail post.
