The Heavy Duty Titeseal® Copolymer Slide Gate is a non-metallic, corrosion resistant gate that provides the engineer with a superior alternative to stainless steel and cast iron slide gates, often called sluice gates. It is designed to handle high head applications of 10 feet or more in seating or unseating service. The guide includes a top closure bar that allows the gate to seal around all four sides. A wedging bar and adjustable wedging bolts allow the leakage rate to be adjusted to the lowest possible levels.

Industrial Slide gates are commonly used in open channel and moderate head applications to isolate equipment, divert flow, close off a wall opening, or cover a pipe that is flush with the wall. Plasti-Fab slide gates are manufactured of gray fiberglass reinforced plastic containing ultraviolet inhibitors. Plasti-Fab penstock is reinforced to withstand the specified maximum operating head. Where required neoprene j-seals can be included to meet low leakage rates. The frames are constructed from Plasti-Fab designed FRP pultrusions with polymeric fiber surfacing material and UV inhibitors for high corrosion resistance.

Plasti-Fab stop gates are individually molded using fiberglass reinforced polyester resin containing UV inhibitors to the exact size required for each application. Most stop gates utilize a sandwich construction with a closed-cell polyisocyanurate foam core for high strength and corrosion resistance. A totally encapsulate internal steel structural matrix is often used to meet deflection requirements for larger gates. The frames are constructed from Plasti-Fab designed FRP pultrusions with polymeric fiber surfacing material and UV inhibitors for high corrosion resistance. Guides may be embedded, surface mounted or in-channel mounted.

Plasti-Fab heavy-duty stop logs feature a unique seamless construction that fully surrounds an internal structural skeleton. This means that there are no seams, glued joints or cracks in the outer skin that can allow seepage to penetrate the interior steel support structure. Composite stop logs are the perfect alternative to use for a long-term solution compared to metal or wood logs.

Plasti-Fab was a leader in the flume fabrication revolution that began over forty years ago and has thousands of flumes working in corrosive environments around the world.


All Plasti-Fab flumes have precise throat dimensions for accurate flow measurement, and are coated with a premium grade isophthalic gel coat providing a smooth non-porous surface for enhanced flow passage and long term UV protection. Head gages for visual fluid level checking are standard on all flumes.

The FRP Rotating Scum Skimmer is designed for rectangular basins. Typical sizes range from 6 ft. to 20 ft. in length, and 6 inches to 18 inches in diameter. Most are manually operated with a lever arm. A handwheel or electric operator are available options. Normal maintenance consists of routine plant wash down. Typical applications include: grease and scum in primary basins; surface oil in oil/water separators; foam and process debris in industrial basins; byproduct decant in certain industrial separation basins; and/or the removal of leaves and other floating organic debris in water plant sedimentation and chlorination basins.

The Plasti-Fab Composite Baffle Wall provides superior corrosion resistance while providing the flexibility of custom fabrication to meet specific application needs. All composite parts are guaranteed against corrosion.

As a leader in corrosion resistant equipment for fluid measurement and control, Plasti-Fab has thousands of gages installed in corrosive environments around the world. Plasti-Fab products are fabricated from highly corrosion resistant composite fiberglass reinforced plastic (FRP) with a 25 year corrosion warranty. Plasti-Fab has made Fiberglass head Fluid Level Gages for use in open channel flumes for over 20 years. Due to market demand, we now offer this same durable construction in all sizes of custom level fiberglass gages.

Plasti-Fab fiberglass Launders and backwash Troughs are typically designed for clarifiers and gravity filter systems in water/wastewater treatment plants. Long lasting Troughs are available in all sizes with flat,round, or V-shaped bottoms. Weir Plates and Scum Baffles are available for FRP or concrete troughs. Plasti-Fab troughs are made of highly corrosion resistant composite FRP. They are light-weight and easy to install and are virtually maintenance free.
