Fiberglass Reinforced Plastic (FRP) fiberglass duct products serve a wide variety of applications both industrial and commercial. Our FRP ducting is highly customized and durable.

With decades of experience, Industrial Plastic Systems can manufacture and fabricate the fume removal system that you need. While the majority of duct systems are round, we offer square and rectangular sizes to suit your application. The straight Fiberglass duct is typically filament wound for its stiffer wall and better support spacing. Fittings and joints would be contact molded. Most FRP Fiberglass duct is built with a fire retardant vinyl ester resin system which is cost effective and meets most service conditions.
