Marine Composite Decking

Marine Composite Decking

Superior water- and UV-resistance makes Latitudes® Marine decking shipshape for building docks, boardwalks and other waterfront structures. Wood decking in the same application severely fades, warps, splits and rots, while Marine decking keeps looking great and performing well year after year. Plus, its slip-resistant finish provides more sure footing—an especially nice quality for surfaces that are often wet.

Latitudes Marine decking is offered in stouter boards (1-1/4" thick by 5-7/16" wide) designed for 24" on-center joint spans are common to marine construction. It is made using the same exclusive Strandex® technology as all of our Latitudes marine boards, comes in the same four colors, and provides the same exceptional longevity and low maintenance requirements. All of which makes Latitudes Marine decking the peerless choice for your next waterfront project.
