Pultruded gratings are made by assembling the FRP pultrusions which are manufactured with a high percentage of glass fiber roving soaked with resin and finally designed to desired shapes by heating and pultrusion.
Pultrusion is a continuous process in which the glassfibers, glass matting and a synthetic surface veil are literally “pulled” simultaneously through a polyester or vinyl ester resin bath. The desired geometric shape is formed as they are pulled through a heated steel die as the composite hardens.
Pultruded gratings are light weight, strong, chemical and UV resistant with less maintenance. Pultruded gratings are well suited for highly corrosive environments and offers very high load bearing capacity.

Application of FRP grating:

-Water treatment: overhaul aisle, gutter cover, large container, washer, trash rack, flow tank, biochemical water treatment tank hanger, ventilation window, stairs, cooling tower console.

-Chemical plant: stair raft, operating platform, guardrail, double floor, trench cover, grating.

-Petroleum industry: offshore oil platform.

-Textile mill: instead of metal grille, wooden platform and covered with cement floor, bleaching and dyeing tank, floor, valve nearby, etc.

-Power plant: chemical water workshop trench cover, wastewater pool, etc.

-Metal surface treatment: pickling place, replacement of wooden floor around machine, high corrosive container, plating line walkway, double floor.

-Marine food processing plant: harsh environment such as slippery surface, on board.

-Transportation: platforms, ship decks, walkways, military minesweepers, stair seesaws.

-Beverage industry: stair rafts, alternative expensive stainless steel, loaded floor.

-Pulp and processing plants: Stairs and slabs, floor walkways, places with high humidity.

-Electronics industry: trench cover, pickling workshop, anti-static (anti-static grille) and high cleanliness workshop.

-Meat processing factory: easy to corrode the ground, stairs, slippery floor workbench and stair seesaw.

-Car wash room / car beauty shop: car wash room drainage board, parking space, car wash floor trench cover.

-Crane: on the aisle of a 3m or 6m long crane.

-Others: corrosion-resistant shelves, decorations, square fountains, scaffolding, civil building facilities, aquaculture fences and double-floors.
