  • What is FRP?

    FRP (Fiberglass-Reinforced Plastics) is a general term relating to the reinforcement of plastic with fibrous glass. Typically, this extends the operating temperature of the material to approximately 230℉ (110℃) and the tensile strength (in psi) to approximately ten times that of PVC.

  • Why are some series of gratings marked with "ADA"?

    ADA stands for Americans with Disabilities Act. Gratings marked with "ADA" means they are ADA-compliant in design.
