C-glass and E-glass roving produced by no twist strand through parallel winding to form a cylindrical package. The different roving adopt different composition, linear density and size can separately use for the FRP produced through SMC, BMC, spray up, filament winding and pultrusion process. Our glass fiber roving mainly include: E(C)R20roving, filament winding roving, SMC roving, spray up roving and so on.
