About
Plasti-Fab, operating as a brand within NOV's Fiber Glass Systems division based in Tualatin, Oregon, manufactures fiberglass-reinforced plastic (FRP) flow control and flow measurement products for water and wastewater treatment. With over 40 years of experience in corrosion-resistant fluid management, the company designs products specifically for harsh chemical and wastewater environments. Plasti-Fab's flow control line includes FRP flap gates with flexible neoprene seals, standard-duty and heavy-duty gates, penstocks for channel isolation, and heavy-duty stop logs for emergency shutoff. On the measurement side, Plasti-Fab is recognized for fiberglass flumes and weirs installed worldwide in corrosive environments, along with packaged metering manholes that integrate measurement structures into single-unit installations. Additional products encompass scum skimmers, troughs, launders, baffles, and custom-engineered structural composite components. The FRP construction delivers superior corrosion resistance compared to metal alternatives, making these products suitable for seawater, low-pH, and chemical-laden wastewater applications. Plasti-Fab serves municipal wastewater treatment plants, industrial process water facilities, and corrosive fluid handling installations across North America.
