Plastic steel sign pile: easy to damage, the material is plastic steel (PVC, polyvinyl chloride). Light material, good elasticity, acid and alkali corrosion resistance, good anti-aging performance. Easy to install and transport. No recycling value, natural anti-theft.
FRP mark pile: the cost is slightly higher, and it is made by pressing at high temperature. Impact resistance, wear resistance, high temperature resistance, corrosion resistance, can resist water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, urine, asphalt, suitable for a variety of acid-base soil. Service life up to 30 years. The content adopts screen printing technology, which has good warning effect and does not require maintenance. Light weight, easy to transport and install. No recycling value, natural anti-theft.
