Usually, the materials used for marker piles can be divided into various types, with cement being one of them. It is composed of concrete and steel bars, which are traditional materials that can easily blur handwriting and are not acid resistant, making transportation and installation inconvenient. The plastic steel is mainly made of PVC, which has the characteristics of portability, acid and alkali resistance, corrosion resistance, aging resistance, etc. Fiberglass reinforced plastic is made by pressing at a high temperature, and has the characteristics of impact resistance, wear resistance, and corrosion resistance. Due to its ability to resist gasoline, alcohol, electrolytic salts, acetic acid, and hydrochloric acid, fiberglass is suitable for various acidic and alkaline soils. Resin sand is a material that has been molded in one go, and its long service life is one of its highlights. Its surface is treated with intaglio, and the font and pattern are not only clear, but also very beautiful. Magnesite is a modified magnesite cement used as a cementitious material, which can solve the problem of important underground facilities being cut off. It is widely used in various areas such as busy markets, scenic spots, green belts, and shrubs.

在选购标志桩时，需要选择大型厂家生产的产品，大型厂家的产品一般生产技术较为完善，产品质量好，对客户来说既有保证，又有良好的售后服务，遇到问题可以及时。看产品的质量，俗话说，一分价钱一分货，好货不便宜，便宜没好货，所以好东西上的差别不会太大。注意警示桩的颜色，大厂家生产的产品颜色鲜明，警示性好。该产品主要用于室外，需要适应各种的恶劣天气，如果它上面的字体被侵蚀，就不能起到警示作用了，所以购买时需要特别注意产品的颜色。标志桩使用寿命的长短也是影响我们购买的一个因素，好的产品使用寿命在30-50年，采用的材料达到了要求，有利于保护环境。产品的生产工艺也是比较重要的，好的工艺决定产品的质量，只有生产工艺精细，才能有好的产品。

When purchasing sign piles, it is necessary to choose products produced by large manufacturers. Large manufacturers generally have relatively complete production technology, good product quality, and provide customers with both safety assurance and good after-sales service. If problems are encountered, they can be solved in a timely manner. Judging by the quality of the product, as the saying goes, you get what you pay for. Good goods are not cheap, and cheap goods are not good. Therefore, the price difference of good things is not too big. Pay attention to the color of warning posts. Products produced by large manufacturers have bright colors and good warning performance. This product is mainly used outdoors and needs to adapt to various adverse weather conditions. If the font on it is corroded, it cannot serve as a warning. Therefore, special attention should be paid to the color of the product when purchasing. The length of the service life of the marker post is also a factor that affects our purchase. A good product has a service life of 30-50 years, and the materials used meet environmental requirements, which is beneficial for protecting the environment. The production process of a product is also quite important. Good technology determines the quality of the product, and only with fine production technology can good products be produced.

燃气玻璃钢标志桩的安装事项主要有以下几个方面，一是安装时可能会有两种情况发生，在管道的正上方进行安装或者管道正上方并没有安装条件，但是必须要安装，遇到这种情况，我们可以设置在距离较近的路边绿化带内，但是一定要在产品上设置管道走向图，指明管道的具体位置。二是一般情况下它的安装间距是50-80米之间为宜，安装间距必须要便于日后观察，还要考虑到经济性、实用性和目前实际应用情况。三是燃气玻璃钢标志桩的位置可以适当提升一些，这样更便于观察，增强实际运用，如果是设置在街坊管处的产品是可以适当低一些的，这个不作具体的规定，可以根据自身的情况来决定。

The installation matters of gas fiberglass marker piles mainly include the following aspects. Firstly, there may be two situations during installation: installation directly above the pipeline or installation conditions are not available above the pipeline, but installation must be carried out. In such cases, we can place them in nearby roadside green belts, but it is necessary to set up a pipeline routing diagram on the product, indicating the specific locations of the pipeline. Secondly, in general, the installation spacing should be between 50-80 meters. The installation spacing must be easy to observe in the future, and consideration should also be given to economy, practicality, and current practical applications. Thirdly, the position of the gas fiberglass marker post can be appropriately raised to facilitate observation and enhance practical application. If the product is set at the neighborhood pipe, it can be appropriately lowered. There is no specific regulation for this, and it can be determined based on one's own situation.
