Thermosetting urethane acrylate resin takes the rigors of manhole and drain covers installed in roadways.

Scott Bader Co. Ltd.’s Crestapol resin is used in resin transfer molded covers made by Structural Science Composites Ltd. of Barrow in Furness, England. Such manhole and drain covers are lighter in weight than conventional steel and concrete covers, yet match the materials in load-bearing properties, according to Scott Bader.

Scott Bader, based in Wellingborough, England, says Crestapol is a low-viscosity material with a rapid, low-temperature cure that allows Structural Science to make the covers efficiently.

Structural Science’s covers in its Thrubeam lineup typically weigh a third to a quarter as much as steel or concrete covers — simplifying installation and maintenance — but they also provide long-term performance. Road safety standards specify that covers need to withstand loads of up to 22,000 pounds.
