FRP Grating
From Self-sufficiency
Fiberglass reinforced plastic (FRP) grating is manufactured by combining a matrix of resin and fiberglass. That makes it a composite material. Fiberglass grating does not corrode like steel gratings. That is what gives them their value. They are used in corrosive environments. They lower maintenance costs.
Types
Molded Grating is made on a mold. Pultruded Grating made by joining pultruded profiles into the shape of a grating.
Resins
Many resin types may be used in pultrusion including polyester, polyurethane, vinylester epoxy, & isopthalic polyester
