When pin protrusion is 2-2 1/2" a standard nylon sling can be used for lifting the stop logs; By putting 1 eyelet around each end of the lifting peg. Use 2 slings per log.

What are fiberglass stop logs used for?

Fiberglass stop logs are used to control, isolate or divert water flow in water and wastewater treatment applications. They can be used in channels, basins and other treatment structures where temporary flow control or isolation is required.

What are Glass•Steel® stop logs made from?

Glass•Steel® stop logs are fabricated using fiberglass reinforced plastic (FRP) materials designed for water and wastewater treatment environments.

Are fiberglass stop logs corrosion resistant?

Yes. Fiberglass reinforced plastic will not rust or corrode like conventional metal materials, making FRP stop logs well suited for demanding water and wastewater treatment environments.

Can Glass•Steel®, Inc. fabricate custom stop logs?

Yes. Glass•Steel®, Inc. can fabricate fiberglass stop logs to meet project-specific dimensions, configurations and application requirements.

Where can fiberglass stop logs be installed?

Fiberglass stop logs can be used in water and wastewater treatment plants, channels, basins and other structures requiring flow isolation or control.

What are the advantages of fiberglass stop logs?

Fiberglass stop logs provide a durable, corrosion-resistant and lightweight solution for flow control. Their FRP construction can also help reduce maintenance requirements in water and wastewater treatment environments.

Glass·Steel®, Inc. stop logs use an isophthalic polyester resin system for both the skin and core. Because the skin and core utilize the same resin system, their coefficients of thermal expansion are identical, unlike designs utilizing a metal core.

Type 2 stop logs have a polymer concrete core with a 1/8-inch-thick FRP skin. Type P stop logs utilize a hollow-core design. Both types use sponge neoprene rubber seals attached to the bottom of each log to provide sealing between individual logs and between the bottom stop log and the floor or bottom closure.

Type 2 stop logs utilize J-bulb neoprene side seals located on both inside faces of the guide frames to provide sealing against flow from either direction. Type P stop logs utilize a seal on the side of the slide guide opposite the applied pressure.

Fiberglass Stop Logs Applications

Glass·Steel®, Inc. custom designs and fabricates fiberglass composite stop logs for temporary storage and control of water in flow channels at water and wastewater treatment plants. Stop logs are custom sized to meet project requirements, with thickness determined according to span and differential head pressure.

Glass·Steel®, Inc. fabricates two primary stop log designs: Type 2 and Type P. Both designs incorporate integral lifting pins and can be installed and removed using a specially designed lifting beam.
