ABSTRACT:
A decking plank for attachment to a support structure, such as wood deck joists, said decking plank comprising a unitary, elongated steel member including an upper panel, first and second generally upstanding walls for supporting the upper panel, and first and second mounting flanges for mounting the decking plank to the support structure, and wherein an outer surface of the upper panel is provided with a non-slip coating, and wherein the generally upstanding walls are spaced a selected distance from one another and the upper panel has a width exceeding the selected distance so as to create an overhang adjacent each generally upstanding wall for at least partly concealing the mounting flanges upon the installation of multiple ones of the decking plank in adjacent, side-by-side relationship. In another preferred form the invention comprises a method of manufacturing a steel decking plank for attachment to a support structure, such as to wood deck joists. The method comprises a first step of roll-forming corrosion-resistant steel to obtain a roll formed steel element with a desired shape including an upper panel, side walls, and mounting flanges. The roll formed steel element is then cleaned to prepare it for a subsequent coating operation. A coating is then applied to at least an upper surface of the roll formed steel element and the coating is then cured. Before the coating is fully cured, a grit is applied to the upper panel.
