Introduction to some other parameters of fiberglass marker posts: The panel text is made of imported ink and screen printed, without fading!

1. Tensile strength ≥ 160 MPa

2. Bending strength after immersion ≥ 150 MPa 2. Bending strength ≥ 190 MPa

3. Ring steel degree (5%) ≥ 50KPa4, Babbitt hardness ≥ 38

4. Thermal deformation temperature ≥ 160 ℃

5. Oxygen index 26%

Plastic steel marker post: Plastic steel marker post is based on hard PVC material as the base material, and is made into different forms of square columns, triangular or circular piles through extrusion and cutting with grinding tools. Similar to fiberglass marker posts, imported ink is produced into different text layouts through screen printing.

The advantages and characteristics of plastic steel marker posts:

1. Lightweight material, easy to install and transport.

2. Simple materials and low cost

3. Antioxidant, acid and alkali resistant, suitable for long-term use in saline alkali or desert areas!

Buried marker posts are divided into cable marker posts, oil and gas marker posts, communication marker posts, optical cable marker posts, tap water marker posts, railway marker posts, and highway mileage piles according to their different purposes. Mainly classified based on the purpose of the product and the content printed on it.

According to the installation location, it is also called marker post, marker post, corner pile, hydrological pile, section pile, etc.

Material of marker posts: In traditional craftsmanship, marker posts are generally made of concrete, with some internal materials such as steel bars glued together to fix the columns at high temperatures. Different words are printed on them to create them. However, with the progress of society and the development of human civilization, cement marker posts are prone to blurred handwriting due to transportation limitations and traditional materials, and require regular maintenance. Not acid resistant, heavy material, and inconvenient transportation and installation are gradually being phased out by people, replaced by the widely used fiberglass and plastic steel marker posts at present.

Fiberglass marker posts are generally divided into organic fiberglass and inorganic fiberglass. They are widely known as inorganic marker posts formed by pulling and extruding fiberglass wire. These fiberglass marker posts are made by high-temperature pressing. Impact resistant, wear-resistant, high-temperature resistant, corrosion-resistant, can resist water, gasoline, alcohol, electrolytic salts, acetic acid, hydrochloric acid, sodium potassium compounds, urine, asphalt, suitable for various acid and alkali soils. The service life can reach up to 30 years. The content adopts screen printing technology, with good warning effect and no need for maintenance. Lightweight, easy to transport and install. No recycling value, natural anti-theft.
