In the past a very long period of time,All the tree protection guards on the both sides of the urban roads were iron materials. However,more and more iron tree gratings were replaced by the FRP grating in city reconstruction.Which materials of grating is much better,the iron grating or the frp grating? which materials has more advantages?
   As you know,If the iron materials'grating exposured humid air for a long time, it would corrosioned and rust.what's more,without good safety measures ,the grating are easy to be stolen. While compared with the iron grating,The FRP grating is corrosion resistant,anti-theft,never rust.and long service life.
  When compared with the wood grating,The excellent features are clear to see.it's high intensity, excellent loading capacity,possessed better properties of toughness.not easy to be damaged while the wood grating easy to go rust,the quality decreased. The FRP grating even are anti-slipping and good wear resistant.As the FRP composite materials no any recycle value,the FRP grating is anti-theft! this feature improved the safety of the traffic roads,avoid the people losing into the mud tree hole as the missing iron covers.
