Guardrail Steel Posts with High Tensile Strength and Impact Resistance
Guardrail post, as a very important part of guardrail, is to be broken into foundation and support the corrugated sheet steel beam, which generally determines the performance of guardrail. Posts can be divided into ordinary steel posts and flange posts. Generally, steel posts are mostly fixed into the soil by post anchors, while flange posts are fixed on the concrete ground. As an outstanding guardrail manufacturer in china we supply several kinds of posts to clients, such round post, square posts, C-section post, U-section post, H-section post, also according to client’s requirements.

RGP-01: Round guardrail posts are installed on the roadside to support the guardrail beam and protect traffic safety.

RGP-02: Galvanized round flange post has well impact resistance and anti-corrosion performance.

SGP-01: Galvanized square posts are packaged in pieces for one bundle with steel strips.

SGP-02: Square flange posts are resistant to high and low temperature, and have long service life.

CSGP-01: C-section posts are usually installed with C spacers, it is also high impact resistant.

CSGP-02: C-section posts are installed on the roadside to protect traffic safety and form a beautiful landscape.

HSGP-01: H-section posts are used with thrie-beam guardrail beam, which can minimize the damage caused by accident.

USGP-01: U-section post is more anti-corrosive after galvanized surface treatment.
Features:
- Post is an important part to support corrugated sheet steel beam, which acts as a cushion.
