How We Build Your Dock

Watch our modular aluminum sections connect with precision-machined beam joiners. Each dock is engineered for decades of maintenance-free performance.

6061-T6 Marine Aluminum

The same alloy used in yacht hulls. Corrosion-resistant, incredibly strong, and never needs painting or staining.

Modular Design

Standard 8′×6′ sections connect with beam joiners. Add, remove, or reconfigure your dock layout as your needs change.

HDPE Floats

High-density polyethylene floats provide stable buoyancy. UV-resistant, impact-proof, and rated for 25+ years of service.

The Engineering Behind the 50-Year Warranty

Every component is commercial marina-grade. The same construction used in public waterfront facilities—built to last generations.

Modular Assembly System

Tongue-and-groove connections. No welding on site. No special tools. Two people can assemble a 200 sq ft dock in under four hours.

Precision Connection System

Each section locks to its neighbor with 4-foot aluminum joining bars—50×70mm extruded aluminum with 4mm wall thickness.

Ø14mm bolt holes accept marine-grade stainless hardware. The double-nut locking system eliminates vibration loosening, even in heavy chop.

Bolt through both rails simultaneously. The joining bar bridges the gap and becomes a structural member, not just a connector.
