General Design

All FRP (fiberglass reinforced plastic) stop logs are manufactured of reinforced
copolymer composite (fiberglass reinforced polyester), totally encapsulating an internal
reinforcing structures. To protect and to assure maximum service life, the resin is
treated with ultraviolet-stabilizers. Our logs are seamless to protect the inner structural
members from corrosion and corrosive chemicals.

Structural reinforcing is utilized to attain the necessary stiffness needed to meet
deflection requirements and the entire log is encapsulated with a laminate not less than
1/4" thick on each side to insure against any permeation by water to the core areas.
Stop logs will be provided with stainless steel allthread lifting pins that extend
through the gate, and permanently secured to the logs with stainless steel nuts and

Each stop log will be marked to reference its intended location.


Stop Log Guides

Stop Log Guides will be made of FRP and are designed to be embedded in grout.
Stop Logs will be built to Engineering specifications, unless otherwise noted.
