FRP duct
FRP (Fiberglass Reinforced Plastic) duct - also called GRP duct(Glass fibre Reinforced Plastic) - is exhaust ductwork made from a thermosetting resin matrix (polyester, vinyl ester, epoxy, or phenolic) reinforced with continuous or matted fiberglass strands. It's engineered specifically for environments where metal ductwork fails due to corrosion - chemical fumes, high humidity, salt air, wastewater odors, etc
Typical Structure (Inside → Out)
Corrosion Barrier
Resin-rich inner surface with resin and fiber glass, no fibers exposed to the airstream.
Structural Layer
Filament-wound glass + resin for hoop/axial strength
Exterior Layer
Resin-rich topcoat with UV inhibitor for outdoor service
