There are primarily two types of fiberglass grating:
2.Conductive fiberglass grating
Fibergalss grating itself is an insulator, non conductive, non thermal conductivity, but in some specific places, it also has a conductive requirements. The detailed operation method is to eliminate the damage of static charge inoculation in the rock layer with a thickness of about 3~5mm. The conductive grating also has same characteristics with traditional glass steel grille ,such as corrosion resistance, flame retardant,anti strike, skid resistance, light weight and practical in refinery and armaments manufacturing factory, high-tech industry, computer room, chemical plants, dry areas and underground mining operations.
