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.

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.
