1. FRP composite material signs pile is the use of glass fiber as a reinforcing material, a synthetic resin as a matrix material of a composite material using a refined pultruded glass fiber reinforced plastic composite material signs pile (tension forming) is our patent product 2. FRP composite material stakes have light weight, corrosion resistance, aging resistance, good sealing performance, safe and beautiful, all-weather protection, to meet the needs of the outdoor projects in all kinds of environments and locations. 3 FRP composite mark pile with excellent insulating material, high performance insulation resistance to prevent leakage at high frequencies to maintain good dielectric properties, non-reflective, non-blocking microwave transmission, does not rust long-term safety. 4 FRP composite mark pile has good corrosion resistance, can resist water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium and potassium compounds, urine, asphalt, for a variety of acid soil, the product itself has a good rain 5. A strong anti-aging properties of FRP composite mark pile impact, the impact is not deformed, high tensile strength, flexural strength and impact toughness, fully meet the outdoor use of safe, it has a good impact resistance
