When evaluating cooling tower structures, pultruded FRP offers massive lifecycle advantages over wood, concrete, and steel. Wood vs. FRP: Wood is prone to rot, biological decay, and fungal attacks due to constant water exposure. FRP is entirely immune to biological decay and requires zero chemical treatment. Steel vs. FRP: Galvanized or carbon steel rapidly rusts in water-treatment environments. FRP resists chemical additives, chlorine, acids, and high-salinity water without degrading. Concrete vs. FRP: Concrete requires complex, lengthy on-site pouring, curing, and expensive foundation engineering. FRP modules are lightweight, prefabricated, and bolt together rapidly on-site.
