3.Micro fiberglass grating
The corridor of the cellular fiberglass grating is lower than aluminum and steel, and it also corrosion resistance. The micro fiberglass grating especially useful for walking on the trolley and the wheelchair,the double layer micro grid can prevent the appearance of the grid and other objects.

Fiberglass Grating is the contemporary and modern alternative to metal grating, it is not only architecturally more attractive; but is also highly resistant to corrosive environments. Fiberglass reinforced plastic grating, commonly referred to as FRP grating is a composite material, which is manufactured by the combination of a matrix of resin and fiberglass. Fiberglass grating is also fire retardant in nature, along with being non-conductive and light weight, making it a popular grating option for industrial structures and various other usages such as; fire escapes, raised floors, platforms, drain covers, protective shields, stair treads, walkways, docks and trench covers. Commonly used for floor grating, FRP is simpler to install than metal grating, due to its light weight. It does not require heavy machinery for the installation.
