Geogrid grille read Shan or Zha?
Geogrid - geosynthetic material used for reinforcement by a regular mesh tensile band,
Normal should read Zha, but because of the dialect or engineering terminology habits, read Shan, habit, this is just a personal idea.
The traditional geogrid is mainly plastic grille and glass fiber grid, but because of the large deformation of plastic grille and glass fiber grille is mainly suitable for the reasons of the road engineering, and a new type of steel plastic composite geogrid.
