FRP PULTRUDED FIBERGLASS
TYPICAL COUPON PROPERTIES
Below are test results for typical coupon
properties of San Diego Plastics' structural fiberglass profiles
(Standard, Fire Retardant, & Vinylester shapes). Properties are derived per the
ASTM test method shown. Synthetic surfacing veil and ultraviolet inhibitors are
standard.
