玻璃钢标志桩得到广泛应用的原因。随着地下管线的大力发展，玻璃钢标志桩也得到了很大的应用。玻璃钢标志桩是一种FRP拉挤型材，它是采用优质复合材料通过高温固化一次性拉挤成型的，产品耐用，能提供长久的保护作用。 The reasons for the wide application of glass steel mark pile. With the development of underground pipelines, glass reinforced plastic is also widely used. Glass fiber reinforced plastic signs pile is a kind of FRP pultrusion profiles, it is made of high quality composite material through high temperature curing of disposable pultrusion, product durability, can provide long-term protection. 玻璃钢标志桩性能优势： Glass steel mark pile performance advantage: 　　1、玻璃钢标志桩的颜色鲜艳美观，字迹图案清晰且长时间不会褪色。 The color of the glass steel mark is bright and beautiful, the writing pattern is clear and the long time will not fade. 　　2、重量轻强度高，使得运输及安装更加的方便快捷，可减轻工作人员的劳动强度。 The light intensity is high, make the transportation and installation more convenient and quick, can reduce the labor intensity of the worker. 　　3、具有极高的绝缘性且拥有耐腐蚀，耐高温，耐磨损等性能。 High insulation and corrosion resistance, high temperature and wear resistance. 　　4、玻璃钢标志桩还具有防盗性，因为玻璃钢是没有回收价值的，自然也就会防盗。 4, glass steel mark pile also has the security of theft, because glass steel is not recovered value, nature also will guard against theft. 　　5、抗冲击性极强且不形变。 Strong resistance to impact and not deformation. 　　6、使用时间长。 Use your time.
