Gas marker posts are generally made of FRP. Why use FRP gas marker posts? Because FRP gas marker posts have unique advantages:

1.比重轻、抗腐蚀、耐老化、密封性能好，美观，具有全天候防护功能，能够满足室外工程项目中各种恶劣环境和场所的需要.

1. light specific gravity, corrosion resistance, aging resistance, good sealing performance, safe and beautiful, with all-weather protection function, which can meet the needs of various harsh environments and places in outdoor engineering projects

2.具备优异的绝缘材料，高性能的绝缘电阻防止漏电，在高频下能保持良好的介电性能,不反射,不阻断微波的传播,不生锈长期使用.

2. it has excellent insulating materials, high-performance insulation resistance to prevent electric leakage, can maintain good dielectric performance at high frequency, does not reflect, does not block the transmission of microwave, does not rust, and is safe for long-term use

3.有良好的耐腐蚀性能,可以抵抗水，汽油，酒精，电解盐，醋酸，盐酸，钠钾化合物，尿，沥青，适合各种酸碱土壤,防雨产品本身具有良好的抗老化性能,

3. it has good corrosion resistance and can resist water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, urine and asphalt. It is suitable for all kinds of acid-base soil. The rain proof product itself has good anti-aging performance,

4.抗冲击力强，撞击不变形,有很高的拉伸强度，弯曲强度和冲击韧性，,完全可以满足户外使用。

4. it has strong impact resistance, no deformation upon impact, high tensile strength, bending strength and impact toughness, and can fully meet the safety requirements for outdoor use.

5.质量轻，适于搬运，安装简单防偷盗，该材料无回收价值，自然防盗.可以地下重要设施被挖断的问题,具有重大的社会效益和经济效益.

5. light weight, suitable for handling, simple installation and theft prevention. The material has no recycling value and is naturally anti-theft It can solve the problem that important underground facilities are cut off, and has great social and economic benefits

6.完全符合要求的材料，满足未来发展需要。在桩体表面印有明显夜光效果的警示标识；补足了水泥标志桩的不足！

6. environmental protection materials that fully meet national requirements and meet future development needs. Safety warning signs with obvious luminous effect shall be printed on the surface of the pile; It makes up the deficiency of cement marker pile!

7.玻璃钢标志桩桩体表面使用特制特种油漆具备性能特点：附着力好；光泽高；丰满度好；硬度高；，能为复合材料玻璃钢标志桩表面提供长久的保护作用！

7. special paint is used on the surface of glass fiber reinforced plastic marker pile, which has performance characteristics: good adhesion; High gloss; Good fullness; High hardness; Environmental protection, can provide long-term protection for the surface of composite FRP sign pile!

燃气标志桩的形状有：

The shapes of gas marker posts are:

方形：80*80*高、100*100*高、120*120*高、140*140*高、150*150*高等，燃气标志桩绝大部分都是方形的。

Square: 80*80* high, 100*100* high, 120*120* high, 140*140* high, 150*150* high. Most gas marker posts are square.

三角形：100*100*100*高、120*120*100*高、150*150*150*高、180*180*180*高等，也有部分使用三角形燃气标志桩。

Triangle: 100*100*100* high, 120*120*100* high, 150*150*150* high, 180*180*180* high, and some use Triangle gas marker posts.
