Material properties:

根据用户对型材的具体力学，电学，防腐蚀，阻燃性等各项要求，设计者须做出合理的材料结构设计和选择合适的原材料组合，包括树脂和增强纤维以及其它各项材料。请参考拉挤玻璃钢物理性能表.

According to the specific mechanical, electrical, anti-corrosion, flame retardancy and other requirements of the user for the profile, the designer must make a reasonable material structure design and select the appropriate combination of raw materials, including resin, reinforced fiber and other materials. Please refer to the physical properties table of pultruded FRP

材料优势：

Material advantages:

高强度、重量轻、耐腐蚀、绝缘隔热、可阻燃性。无电磁性。热膨胀系数低、低温性能好、耐老化、可设计性强、外观美观等等。

High strength, light weight, corrosion resistance, insulation, flame retardant. No electromagnetism. Low thermal expansion coefficient, good low temperature performance, aging resistance, strong designability, beautiful appearance, etc.

玻璃钢拉挤型材呈正方形，各边壁厚均匀，表面光滑，有光泽。尤其观察内部铺毡分布情况，不出现毡覆盖不上的现象，不出现多余树脂堆积情况。表面上手感均匀，无纱线外漏情况，毡层分布均匀等。所以玻璃钢拉挤型材的报价也是不一样的。

FRP pultrusion profiles are square, with uniform wall thickness on each side, smooth and glossy surface. In particular, observe the distribution of the internal felt, and there is no phenomenon that the felt cannot be covered, and there is no accumulation of excess resin. The feel on the surface is even, there is no yarn leakage, and the felt layer is evenly distributed. Therefore, the quotation of FRP pultrusion profile is also different.

复合材料标志桩采用高强度玻璃丝纤维和不饱和树脂拉挤成型，具有外表美观，县泪心，易施工，耐高温耐腐蚀，抗氧化，强度高，不易碎，不可回收利用的优点。

The composite sign pile is made of high-strength glass fiber and unsaturated resin by pultrusion, which has the advantages of beautiful appearance, tear heart, easy construction, high temperature resistance, corrosion resistance, oxidation resistance, high strength, non fragile and non recyclable.

传统的标志桩整体为水泥铸造，字迹不明显，警示性不强，水泥柱体表面易褪色，无导代学头，施工不方便，不易维护，此为一代标志桩。

The traditional sign pile is cast with cement as a whole, with unclear handwriting and weak warning. The surface of the cement column is easy to fade, there is no guide and learning head, and the construction is inconvenient and difficult to maintain. This is a generation of sign pile.

而二代塑钢(PVC)标志桩虽然比重较轻，易施工，外表美观等优点，但是易老化，不有实温，可回收利用(易被盗)等缺点。

While the second-generation plastic steel (PVC) marker pile has the advantages of light proportion, easy construction and beautiful appearance, it is easy to age, has no real temperature, and can be recycled (easy to be stolen).

因此复合型材料地埋标志桩是水泥和PVC标志桩的佳替代品。现已广泛用在天然气、石油、电力、交通、通信、供水、等管道线路上方。

Therefore, composite material marker pile is a good substitute for cement and PVC marker pile. It has been widely used in natural gas, oil, electricity, transportation, communications, water supply, and other pipeline lines.
