Structural materials in common use on cooling towers include galvanized steel, stainless steel and fiberglass (actually a matrix of fiberglass reinforced polyester, the term “fiberglass” is used throughout this report to describe the composite material — also commonly known as FRP).
Industrial Cooling Towers are made from a variety of materials depending on cost, application, and environmental need.
Fiber-reinforced polyester (FRP) has been used as a cooling tower casing material for some time. Pultruded FRP, when made heavy enough, can handle cooling tower loads and provide good corrosion protection. Good quality FRP towers, however, can be nearly as expensive as stainless steel towers.
