SuperPlank® and Flowgrip® both are pultruded as a single profile and offer a unique tongue and groove joint to reduce the number of fasteners and eliminate trip hazards that plague traditional decking products. SuperPlank® and Flowgrip® are fiberglass decking systems that are pultruded in a constant cross-section with the legs and top surface integral to the profile. The unique tongue and groove joint system locks the panels together. The interlock permits shear loads to transfer between each panel while eliminating trip hazards. The profiles are offered as a solid surface or with perforations to allow sunlight or water to pass through.
