The material of the marker post: In the traditional craftsmanship, the marker post is generally made of concrete, and some materials with steel bars inside are glued into fixed columns through high temperature, and then printed different characters on it. , so that it is produced and formed, but with the progress of society and the development of human civilization, the handwriting is easy to blur due to the limitations of transportation and the traditional material of the cement, and needs regular maintenance. It is not resistant to acid, heavy in material, and inconvenient in transportation and installation. It has been gradually eliminated by people.
FRP marker posts are generally divided into organic FRP and inorganic FRP, which are well known are inorganic marker posts formed by fiberglass wire, which are pressed by high temperature. Impact resistance, abrasion resistance, high temperature resistance, corrosion resistance, can resist water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium and potassium compounds, urine, asphalt, suitable for various acid and alkali soils. The service life is up to 30 years. The content adopts screen printing technology, the warning effect is good, and no maintenance is required. Light weight, easy to transport and install. No recycling value, natural anti-theft.
