SunWalk® 45-Series combines large-format efficiency with our original bi-directional design to create marine decking that installs faster and delivers a clean, consistent appearance.
Available in panel sizes up to 5′ × 4′, 45-Series covers more dock surface with fewer panels and fewer fasteners than traditional deck boards. Its 45% open-surface design allows sunlight and water to pass through while helping reduce hydraulic uplift from waves, storm surge and high water.
Lightweight, durable and designed specifically for waterfront environments, SunWalk® 45-Series is an ideal dock decking solution for residential docks, marinas and light-commercial waterfront applications.
From boating and swimming to fishing and relaxing, your dock should be a place you enjoy—not another maintenance project. SunWalk® 45-Series eliminates the painting, staining, splinters and rot associated with traditional wood decking, giving you more time on the waterfront and less time maintaining it.
— Core Technology
Large-Format Panels for Faster Installation
Cover more dock with fewer panels and fewer fasteners.
SunWalk® 45-Series is available in 3′ × 4′, 4′ × 4′ and 5′ × 4′ panels, dramatically reducing the number of individual pieces required to surface a dock compared with traditional deck boards.
The lightweight, precision-molded panels are consistently sized and ready to install, helping dock manufacturers, builders and installers reduce handling, fitting and installation time while achieving clean, repeatable results.
For dock manufacturers in particular, large-format construction means a decking system that’s designed to work efficiently with the manufacturing and assembly process—not against it.
— What sets it apart
How 45-Series is engineered.
Original Bi-Directional Design
Clean, consistent lines—even when your dock changes direction.
The original SunWalk® 45-Series bi-directional design maintains a consistent visual pattern through changes in decking direction. This lets builders create corners, transitions, and more complex dock layouts without sacrificing the clean, uniform appearance of the finished surface.
The result is a large-format marine decking system that combines installation efficiency with an attractive, purpose-built waterfront design.
45% Open Surface Design
Better for the waterfront above and below the dock.
The SunWalk® 45-Series 45% open-surface design allows sunlight to pass through the decking to the aquatic environment below. The open structure also allows water to move through the dock surface, helping reduce hydraulic uplift from waves, storm surge, and high water.
The result is grated marine decking designed to address both the environmental and physical demands of waterfront construction.
SunWalk® Microcellular Core Technology
Strong, lightweight and purpose-built for marine environments.
SunWalk® 45-Series is manufactured using our Microcellular Core Manufacturing Technology, a structural-foam molding process engineered to produce strong, lightweight and dimensionally consistent dock panels.
The technology helps reduce molded-in stress while providing the durability and impact resistance required for waterfront use. Precision molding also provides consistent dimensions and flatness—important advantages for dock manufacturers and installers looking for predictable fit and repeatable assembly.
— Benefits
SunWalk® 45-Series Benefits
Maintenance-Free
No painting, staining, splinters, insects or rot. Spend less time maintaining your dock and more time enjoying it.

Precision Manufactured
Consistent dimensions, exceptional flatness and repeatable quality help manufacturers and installers achieve predictable results.
— Panel Options
Choosing the Right 45-Series Panel
Both 45-Series Premium Reinforced and 45-Series High-Impact provide the large-format efficiency, 45% open design and marine performance of the SunWalk® 45-Series. The primary difference is how each panel is engineered to balance rigidity and impact resistance.
45-Series Premium Reinforced
Maximum rigidity and a more solid feel underfoot.
SunWalk® 45-Series Premium Reinforced incorporates fiberglass reinforcement into the microcellular core, increasing panel stiffness and creating a firmer, more rigid feel underfoot.
It’s an excellent choice for applications where maximum rigidity and structural feel are priorities.
45-Series High-Impact
Enhanced impact performance with excellent everyday durability.
SunWalk® 45-Series High-Impact uses our microcellular core technology without fiber reinforcement. This provides slightly more flexibility than Premium Reinforced while enhancing the panel’s ability to withstand impact.
High-Impact offers an excellent balance of durability, performance and value for residential docks and other recreational waterfront applications.
