Flame Retardant Biaxial Geogrid
http://www.geosynthetics.com.cn        www.geogrid.biz
FR geogrids are well suited for mining grating; they do not contribute significantly to the fire propagation and to the generation of smoke while burning (ISO 9705), being stabilized with fire retardant additive; they are clearly visible, being white in color, when used underground environment; they are strong, durable and easy to install.

[Typical applications]

 

Mining grating - indoor grid - rock protection grid for tunneling - indoor fence.
