ANSI Standard: FRP Composites Grating Manual for Pultruded and Molded Grating and Stair Treads (Digital Download)

The Fiberglass Grating Manufacturers Council (FGMC) of the American Composites Manufacturers Association (ACMA) has issued a new FRP Grating Manual Standard to educate engineers, designers and end-users about the properties, performance and uses of fiber reinforced polymer (FRP) grating. The engineering community relies on recognized standards when specifying materials and the Fiberglass Grating Manual Standard will enable engineers to design and use FRP with confidence.

FRP grating, a composite material manufactured by combining a matrix of resin and fiberglass, is used in many different applications, from walkways in industrial plants to flooring on ships to decorative grids on commercial and residential buildings. It exhibits many features (as compared to metal gratings or wood decks) that are beneficial in a variety of applications. These features include corrosion and rot resistance, lightweight, high strength-to-weight, electrical and thermal non-conductivity and molded-in colors.

The Fiberglass Grating Manual Standard has three sections:

  • Load Tables: A quick reference for engineers to compare the performance of FRP grating types under specified load conditions. 
  • Code of Standard Practice: Representation of generally accepted standard practices in the FRP grating industry.
  • Generic Specification: Suggested guidance for engineers and owners when procurement purchases the grating, keeping all manufacturers on a level playing field; this specification also promotes the manufacturing of gratings that will have minimum performance standards.
