Core-samples from Five Bridges using GFRP were
analyzed in High Corrosion Environments, in two studies 5
years apart; the samples were sent to 4 different
laboratories for evaluation, using different test methods;
the bridges were in service up to 15 years.

In 2010, Intelligent Sensing for
Innovative Structures Canada
updated guidelines for buildingwith GFRP.
In 2006, the Intelligent Structures
of Canada developed a Product
Specification Manual for GFRP
reinforcement for civil application.

TUF-BAR is manufactured using;
Owens Corning Advantex ECR Type Glass
In Corrosive environments, Advantex® glass performance is 12
times that of a laminate made with E-glass.
Ashlands - Derakane™ epoxy vinyl ester resin
offers proven excellence in corrosion-resistant fiberglass
reinforced plastic (FRP) applications, including exceptional
durability, superior heat resistance, low maintenance and high
performance for even the most challenging environments.
