FRP ductwork and exhaust stacks are used to control corrosion in corrosive air pollution and odor abatement HVAC systems.  Ducting and stacks fabricated of FRP are usually substantially superior to duct systems fabricated using lower grades of stainless steel or lined steel.  Since FRP ducting is lighter than metal ducting, it is more economical to install and is easily field modified.
