With the continuous rapid development of China's economy, the speed of urbanization construction in various regions is accelerating, and the construction of urban water, electricity, natural gas and other underground infrastructure pipe networks also ushered in rapid development. In particular, the underground gas pipeline network is responsible for the energy supply, information transmission and life development of the whole city, which is closely related to life and production. Therefore, it is necessary to install unified markers near the underground official website.
According to the requirements of relevant laws and regulations, signs must be installed near the underground natural gas, power cables, communication facilities, water conservancy equipment, railway geographic pipelines, etc. This is called marker post, also known as marker post. Generally speaking, marker posts can also be installed in green belts, bushes, scenic spots and other places where pedestrians and vehicles need to be warned.
Marker posts are widely used in electric power and other industries, and selecting marker posts is no small learning. Take the gas marker post as an example. How to select the gas marker post with long service life and convenient maintenance often gives many purchasers a headache.

Most of the common gas marker posts on the market are made of fiberglass. FRP material is a new composite material, mainly composed of glass fiber, resin and other materials, and glass fiber determines the strength of FRP material. Good fiberglass fiber, such as alkali free fiberglass fiber, has higher strength than steel wire, and also has a certain degree of toughness.
The advantages of gas marker posts are more than that. Because the alkali free fiberglass fiber is stable in nature, has good weather resistance, almost does not absorb water, and will not burn in case of fire, there is no doubt about its safety. Of course, the price of this alkali free FRP material will be slightly higher than that of inferior FRP materials.
The strength of the marker post is not inferior to that of steel. Compared with steel, the quality of the marker post is lighter, which is only one fourth of the steel and one tenth of the concrete material. It is convenient for transportation and handling, which saves manpower, reduces workload and improves work efficiency. In addition, it also has the characteristics of strong external impact resistance, chemical corrosion resistance, wear resistance, high temperature resistance, and can be used for a longer time in the outdoor environment of wind and rain.
