The lightweight AMERIBOARD FIBERGLASS (FG) 1203 pultruded fiberglass decking plank has been designed for exceptional performance in harsh corrosive environments. Exhibiting a bending strength greater than that of steel with nearly twice the stiffness of a typical pultruded plank, this high strength FRP decking will span further and hold greater loads than ordinary pultruded FRP deck planks. The AMERIBOARD FIBERGLASS (FG) 1203 PLANK features an integrated wearing surface that is formed during the pultrusion process. The integral wearing surface reduces the plank weight by eliminating the need for a secondary applied antiskid surface. The AMERIBOARD plank system has been designed for ultimate strength and stiffness. In fact, it was designed to replace 2.5in. thick solid timber decking.
