Improved water cooling towers are provided which include pultruded fiberglass reinforced plastic (FRP) structural components and assemblies. To this end, integrally formed, pultruded channels (26, 26a) are provided having central web sections (28, 28a), endmost flanges (30, 30a, 32, 32a), and obliquely oriented, reinforcing legs (34, 34a, 36, 36a). Pultruded tubular columns or beams (68) are also provided having thickened central wall sections (94, 96, 98, 100) and relatively thin corner sections (102, 104, 106, 108). In order to connect the beams (68) and channels (26, 26a), use is made of connectors (110) having pultruded FRP sleeves (118) and an associated bolt and nut assembly (112, 114). The sleeve (118) is designed to pass through aligned apertures (120, 124, 122, 126) in the beam walls and channel member sections to provide greater strength and shear capacity.
