SUBSTRUCTURE:
Sub-frames consist of a 12” box truss design composed of side panels which feature 1 ½” x 1 ½” x 3/16” angle for the top & bottom cords and 1 ½” x 1 ½” x 3/16” angle members for the diagonal web in the side panels. Cross trusses are located every 4’ with a diagonal between each truss on the bottom of the section against the floatation. 3” x 3” x 3/16” angle corner members are used where sections are joined with grade 8 bolts. COMPONENTS are hot dipped galvanized

CONSTRUCTION METHOD:
Finger are positioned between head pier sections creating a pre-engineered reinforced joint where members meet. This is much stronger than simply attaching each section to the head pier as many builders do. Each finger section and head pier section are fabricated as an individual member then hot-dip galvanized. We also utilize underwater bracing as required for additional support, especially for wider or longer slips, or slips without roof systems. Wind bracing is also used for taller roof systems.

FLOTATION:
Floatation is roto-molded polyethylene tubs filled with white expanded polystyrene. Size and spacing of floats are determined in the engineering process to achieve load specifications for the project.

DECKING CHOICE:

• Treated lumber; 2”x6” cross decked and screwed to treated 2”x4” sills tech screwed to sub-frames.
  
• Composite; Choice Dek and other popular brands, installed directly to subframe. Many dock manufacturers use treated lumber runners to simplify the installation of the composite material. We tech screw composite decking to frames at recommended intervals by the manufacturer, to increase the life of the deck.
  
• Concrete tiles: available per customer specification. We have many choices of concrete, ranging from a plain grey concrete to a natural looking aggregrate, painted surfaces, and even a tile with a marble look and feel.

Samples of Concrete:

METAL CANOPY:
Our standard roofing system consists of vertical columns constructed of 2 ½” sq. tubing which are bolted to the sub-frame with cross trusses in the substructure between each pair at their base.

Purlins are 2 1/2 or 3 ½” x 8” galvanized 14 ga. “Z” with a maximum spacing of 8’. Heavier columns and purlins are used as required for larger slips and docks.

Roofing consists of 26-ga. "R-Panel" attached to purlins with gasketed, self-tapping hex head roofing screws and the seams are fastened with stitching screws. Many choices of roofing are available with a veriety of colors, gauges and rib patterns to match your job's requirements.

Wind bracing on superstructure is used as determined in the engineering process on a per job basis.

ANCHORING:
Anchoring typically consists of size D galvanized cast iron winches attached to our corner mounted winch towers.

Winches are spooled with ½”galvanized aircraft cables, which terminate at concrete sea anchors outboard and shore anchors on land.

We utilize spud poles and stand off systems where conditions are appropriate.

GANGWAY:
Gangway's have handrails on both sides.

The Signature series features 3” square tubing handrails trussed with 1 ½” square tubing.

The Standard series features 2” x 3/16” angle handrails trussed with 1 ½” x 3/16” angle.
