Profile: Indiana Group of Companies is a manufacturer of floor gratings, safety handrails, cable trays, cable management systems, welded wire mesh, conveyors, and bulk material handling equipment. Our FRP gratings are manufactured by inter-weaving of wetted fiber glass strands with a thermosetting resin system. Liquid resin and glass rovings are poured into the standard mold manually. They are suitable for working platforms, walkways, ramps, stair treads, and bridges. They are used in chemical, petrochemical, refineries, oilfields, ports, and sewage water treatment plants. Slat conveyors are used for packings such as handling bags of fertilizer and cement. Slats are wooden or metal mounted conveyors on double strand roller type pin and bush chain.
