RGC Truss Dock

RGC’s Truss Dock features extreme stability and durability. The open truss design allows the waves to roll through, while maintaining stability and strength yet is lighter than solid sided frames, making this dock ideal for removal at the end of the season.  The truss design also makes the truss freestanding dock ideal to withstand the rigors of busy waterways.

We can top your dock with powder-coated aluminum or DeckWave® poly decking. You can also choose from multiple size options for the sections, ramps and decks, with individual sections up to 16 feet long.

RGC Marine Truss Dock Features

CUSTOMIZE. Your dock, your way.

RGC docks offer a wide variety of section sizes to best suit your needs and requirements, so nearly any configuration is possible.  Choose from 2′, 4′, and 5′ wide sections in varying lengths, sundecks, ramps and corners for endless design possibilities.  Here are just a few possible configurations:

Possible T9 Dock configurations

The Truss Dock is easily adaptable for various water depths and shorelines and can be configured to accommodate break walls. In addition, this dock can be set up as a floating dock using our high density foam floats.  Adjustable external legs offer further installation flexibility. Available in your choice of decking options: mill finished aluminum and DeckWave® poly decking.  Finally, accessories such as dock stairs, benches, ramps, wheels and more let you customize this dock your way.


DURABLE & LOW MAINTENANCE. So you can spend more time relaxing and having fun.

The Truss Dock frame is built with only marine-grade aluminum that will never rust or corrode. In addition, all our decking choices are durable, long lasting and do not require painting or sanding.  Cool to the touch and fade and stain resistant are also features of Powder-Coated Aluminum and Poly Decking.  You can rest assured that the truss dock frame and decking will stand up to the elements of the harsh weather and marine environment.

EASY installation, adjustments and removal.

Easy-to-assemble sections can be modified and repositioned without needing special tools or equipment. In addition, easy-to-adjust Screw Adjustable Legs make for easy alteration and leveling from the top of the dock without the need to get in the water.  All of this in a lightweight truss design, for fast, easy installation, adjusting and removal of your dock.

SAFE.  Safety is in the design.

Safety is a top priority at RGC Marine.  Our docks are designed with your safety in mind, for outstanding stability even in rough waters.  We only offer decking options that are slip resistant and will never splinter or rot.  In addition, you can choose from a variety of accessories that further enhance the safety of your dock.
