Better marine decking starts with better engineering
SunWalk® decking is designed and manufactured specifically for docks, marinas, piers and demanding waterfront environments. At the heart of our products is SunWalk® Microcellular Core Manufacturing Technology, a structural-foam molding process that produces strong, lightweight and dimensionally consistent marine decking panels.
Combined with precision molding, UV protection, integrated non-slip surfaces and purpose-built panel designs, this technology helps SunWalk® deliver the strength, durability, safety and manufacturing consistency required for life on the waterfront.

What Is SunWalk® Microcellular Core Technology?
Strength and durability engineered into every panel.
During manufacturing, a controlled cellular structure is created within the core of each SunWalk® panel. This structural-foam molding process helps reduce molded-in stress while producing a strong, lightweight decking panel with excellent impact resistance and dimensional stability.
Unlike natural wood, precision-molded SunWalk® marine decking isn’t subject to the same variations, splintering, rot, curling and cupping associated with lumber. Consistent dimensions and exceptional flatness also provide dock manufacturers and installers with predictable fit and repeatable results.
The result is marine decking engineered to be strong enough for demanding waterfront applications, yet lightweight enough to make handling and installation easier.

Precision Manufacturing for Better Dock Building
Consistent panels make better docks easier to build.
SunWalk® panels are precision molded to provide consistent dimensions, flatness and quality from panel to panel. For dock manufacturers, builders and installers, that consistency means less variability during assembly and more predictable installation.
Lightweight construction, larger panel options and fewer required fasteners can further reduce handling and installation time compared with traditional individual deck boards.

SunWalk® isn’t simply designed to perform once the dock is in the water. It’s designed to work better throughout dock manufacturing and installation.

— Perfectly Engineered
Engineered for Demanding Waterfront Environments
Marine decking should be designed for marine conditions.
Docks and marinas face constant exposure to sunlight, water, changing temperatures, heavy use, waves and severe weather. SunWalk® decking combines Microcellular Core Technology with UV protection and impact-resistant construction to provide dependable long-term performance in these demanding environments.
Our products are engineered for residential docks, commercial marinas, piers, waterfront walkways and other applications where durability, safety and low maintenance matter.
— Safety
Safe, Comfortable Non-Slip Marine Decking
Sure-footed and comfortable, wet or dry.
SunWalk® incorporates non-slip surface technology designed specifically for waterfront use, providing comfortable and secure footing in wet and dry conditions.
The 90-Series features a precision laser-etched, 360° non-slip surface and ADA-compliant design, making it particularly well suited to marinas, commercial docks, public waterfronts and other applications where accessibility and secure footing are priorities.
— Open Surface
45% Open-Surface Marine Decking
Designed for the waterfront environment.
SunWalk® 90-Series and 45-Series feature a 45% open-surface design that allows sunlight to pass through the decking to the aquatic environment below.
The open design also lets water move through the decking rather than forcing the entire dock surface to resist it, helping reduce hydraulic uplift from waves, storm surge, and high water.
For waterfront projects where light penetration, water movement and storm performance matter, SunWalk® provides an engineered alternative to traditional solid-surface decking.

Low-Maintenance Decking Built for the Waterfront
Less maintenance. More time on the water.
SunWalk® marine decking requires no painting or staining and won’t splinter or rot like traditional wood decking. UV protection and durable, precision-molded construction help maintain appearance and performance through years of waterfront use.
Dock owners
For dock owners, that means less time maintaining the dock.
Manufacturers & installers
For manufacturers and installers, it means a consistent, purpose-built decking system.
Everyone on the waterfront
And for everyone using the waterfront, it means more time enjoying it.
