Marker posts, also known as marker posts, instruction piles, identification piles, ground piles, marker posts, and marker posts

Divided by shape: square, circle, triangle

Classified by material: cement marker posts, plastic steel marker posts (PVC, polyvinyl chloride), composite material marker posts

Production method: pultrusion and molding

The fiberglass marker post is made of fiberglass as the reinforcing material, calcium powder as the filling agent, and synthetic resin through high-temperature one-time extrusion molding

Processing technology: screen printing, laser engraving, mechanical engraving

The characteristics of fiberglass marker posts (FRP advantages include: ① lightweight and high-strength; ② chemical corrosion resistance; ③ good heat resistance and insulation, insulation, suitable for handling, convenient installation, environmental protection, and beautification effect)

Application: Commonly used in power, communication, gas, tap water, buried railway pipelines, and path indication signs. Outdoor, green belts, shrubs, both sides of top pipes, pipelines, including gas pipelines, power pipelines, cable routing, optical fiber channels, oil pipelines, water pipelines, etc

Specification thickness: 80 * 80 * 1000 mm Wall thickness 3-5 mm

100 * 100 * 1000 mm wall thickness 3-5 mm

120 * 120 * 1200 mm wall thickness 3-5 mm

150 * 150 * 1000 mm wall thickness 3-5 mm

Installation method: The buried depth of the excavation pit is generally 30 cm, and two 25 cm steel bars are crossed in front, back, left, and right, and fixed with cement stones. Circular road tiles are drilled through the road surface using a circular hole opener according to the required size of the pipeline. The lower part is fixed with cement slurry, and the upper part is flush with the road surface

The surface of PVC marker posts is relatively smooth, while the surface of fiberglass marker posts is relatively rough. However, the strength of fiberglass marker posts is stronger than that of PVC marker posts, and PVC is easily damaged

Cement marker post: The material is concrete, and some parts have steel bars inside. The handwriting is easy to blur and requires regular maintenance. Not acid resistant, heavy material, inconvenient transportation and installation.
