Abstract

Parallel spaced elongated deck planks are extruded of a rigid plastics material, and each plank includes opposite vertical side walls integrally connected by a generally flat top wall and a contoured bottom wall. The bottom wall of each plank is formed by coplanar bottom edge portions and a bottom center portion integrally connected by a pair of inverted U-shaped or semi-cylindrical portions defining parallel spaced downwardly facing semi-cylindrical cavities. Radially positioned and thinner internal reinforcement walls integrally connect the top wall to each semi-cylindrical bottom wall portion, and a vertical center wall integrally connects the top wall with the bottom wall center portion. Elongated aluminum carrier strips cover the wood supporting joists, and each carrier strip has outwardly and downwardly projecting opposite edge portions to direct water from the joists. A series of attachment strips are secured to each carrier strip, and each attachment strip has a metal base strip with a pair of upwardly projecting opposing plastic snap clips. The snap clips engage corresponding flanges projecting inwardly from the bottom wall edge portions of each plank. A cross score line is formed in each base strip between each pair of snap clips which are bonded to the metal base strip along with pads of resilient plastics material located under the bottom wall edge and center portions of each plank.
