Yingnai FRP flat bar is a solid pultruded profile for bracing, spacers, connection plates, kick plates, cover strips and electrical insulation components. Continuous fiberglass reinforcement provides high longitudinal strength while resisting moisture and corrosion. Bar width, thickness, resin formulation, colour, length and machining requirements can be customized for structural fabrication and industrial assembly.
