FRP Composites Grating Manual for Pultruded and Molded Grating and Stair Treads
Fiberglass grating has been manufactured and used since the 1960s. 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, light weight, high strength-to-weight, electrical and thermal non-conductivity and molded-in colors. Due to the relatively low modulus of elasticity of glass fiber reinforced polymers, fiberglass grating is always controlled by the serviceability (deflection) limit state rather than strength limit states. This design methodology results in very high, real safety factors. ACMA is the registered trademark of the American Composites Manufacturers Association. This standard was developed under procedures accredited by the criteria for American National Standards. The list of canvasses that reviewed this standard was balanced to assure that individuals from competent and concerned interests had an opportunity to participate. The standard is available for public input. ACMA does not approve, rate or endorse any item or property device described in this standard. Participation by federal/state agency representatives or persons associated with industry is not to be interpreted as an endorsement of this standard.
