Generally speaking, it is used outdoors, so the FRP marker posts have relatively high requirements for materials. Because outdoor products are easily corroded by harsh environments, and the other is that the long-term temperature difference may lead to deformation, and the third is because of the air corrosion for many years, which may lead to oxidation. Therefore, in the specific use process, it is still necessary to analyze the specific problem according to the specific problem. FRP marker post products mainly play a warning role, if the surface text fades, or there is a corrosion phenomenon.

In this way, the warning effect of it will be greatly reduced, and there will be a phenomenon that the pipeline is dug, and there are great safety hazards. Therefore, the current FRP marker posts are generally made of FRP materials, because this material has better corrosion resistance. At the same time, the wear resistance and impact resistance of this product are very good. And its installation and construction are relatively simple, and the quality is relatively light. Pile text adopts screen printing technology or laser engraving technology, which will not fade, and the service life is as long as 20 years. Electrical environmental protection marker posts are being used more and more now.

It is widely used in various fields, and it has many excellent performance characteristics. Electrical environmental protection marker post is a vertical ground sign, which is a protective umbrella of underground power cable pipelines. It ensures the smooth transportation of our energy life and ensures our normal life order. Generally, it exists in places with underground power and cable pipelines, which play a good warning role for people. At the same time, it is necessary to avoid unnecessary losses caused by the excavation of the underground pipeline. The advantages of FRP electric power environmental protection marker posts: low density, high strength, stronger than steel, and the mechanical strength is about 3-4 times that of steel.

Light weight, easy to carry and install, and the weight is only between one-fourth and one-sixth of ordinary steel. It greatly reduces labor intensity and improves labor efficiency. High temperature resistance, can withstand the high temperature that comes in an instant. Corrosion-resistant, can be well adapted to various harsh environments, lifetime maintenance-free, long service life, and no rust. The anti-theft and FRP material marker posts have no recycling value, which effectively reduces the economic loss caused by theft.
