4×8 Aluminum Dock Frame Section

Patriot Docks Truss Dock Frame – Ultra-Strong. Built to Last.

The Patriot Docks Truss Dock Frame is the backbone of our modular dock systems—engineered with generations of ingenuity in every detail. Perfected through years of real-world shoreline use, customer feedback, and practical refinement, this ultra-strong aluminum frame delivers exceptional strength, stability, and long-term performance.

At the heart of its design is our extra-tall 13-inch truss system—the tallest in its class—built to resist flexing under load and to stand firm against waves, wind, and shifting lakebeds. Whether you're building a stationary dock, a rolling dock, or a custom platform layout, this frame is built to take on the toughest waterfront conditions.

Designed for builders and DIYers alike, the frame is compatible with standard 5/4" x 48" decking boards or Patriot Docks 4×4 drop-in decking panels—available in Western Red Cedar, Reinforced Poly, or Unbeatable Aluminum. Choose the material and mounting method that fits your dock vision.

Key features include:

• Tall 13" aluminum truss frame for unmatched rigidity and durability
• Marine-grade aluminum construction – lightweight, rust-resistant, and field-tested
• Works with bolt-down or drop-in decking
• Pre-drilled utility holes for pipe supports, jack legs, floats, and accessories
• Includes hardware for connecting dock sections
• Requires 4 ft end rail for terminal ends (sold separately)

Whether you're starting from scratch or replacing old dock components, this frame is designed for quick assembly, modular expansion, and decades of use on the water.
