水泥标志桩：材质是混凝土，部分内部有钢筋。传统材质，字迹容易模糊，需要定期维护。不耐酸，材质较重，运输安装不方便。
Cement marker pile: material is concrete, part of which contains reinforcement. Traditional material and handwriting are fuzzy and need regular maintenance. Acid proof, heavy material and inconvenient transportation and installation.
菱镁标志桩：菱镁标志桩是以改性菱镁水泥为胶凝材料、辅以必要的填充料、再以增强材料增强而制成的，是一种新型的标志桩，是水泥、塑钢及树脂标志桩的良好替代品，可有效解决地下重要设施被挖断的问题，主要用作电力、通信、燃气、自来水、铁路等管线路径通道的指示标志兼警告牌。现已广泛应用于各地区闹市、风景区、绿化带、灌木丛及顶管两侧管线路径的指示，市场前景巨大。
Magnesite marker pile: MAGNESITE marker pile is made from modified magnesite cement as cementitious material, supplemented with necessary filling material and reinforced with reinforced material. It is a new type of marker pile, which is a good substitute for cement, plastic steel and resin marker piles. It can effectively solve the problem of excavation of important underground facilities. It is mainly used as electricity. Signs and warning signs for power line, communication, gas, tap water and railway lines.
