Introduction:
It is pressed by high temperature, impact resistance, wear resistance, high temperature resistance, corrosion resistance, can be resistant to water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium and potassium compounds, urine, asphalt, suitable for a variety of acid-base soil. Its service life can be as long as 30 years. It use the screen printing technology, and the warning effect is good, do not need to maintain. Another hand, light weight, easy to transport and install.
FRP stake is FRP pultruded profiles and the use of glass fibre and its products as reinforcing material, calcium powder as filler, synthetic resin as matrix material through FRP pultrusion machine disposable pultrusion.
Application:
It is commonly used in electric power, communication, gas, water, railway buried pipeline path indicator. For outdoor, green belt, bushes, pipe jacking on both sides of the pipeline route instructions.
