For Alumi-Span Docks, they use a unique tongue and groove deck board that hinges together , eliminating the need for welding. Along that hinge and anywhere that metal meets metal, they apply a layer of outdoor-grade subfloor adhesive. The aluminum boards are still attached to the stringers using stainless steel fasteners, but the adhesive takes away the loud rattle often associated with welded metal docks.
The aluminum boards have built-in tread that runs the entire width of the board, so there are no smooth spots that can be slip points. This makes the aluminum dock safe to walk on, wet or dry.
Along the back of the dock section, there is an “I” beam that is supported by a rest on the crossarm. This makes the sections rock solid! In addition, Alumi-Span uses heavier walled aluminum extrusions on both side stringers and deck boards than most other manufacturers.
All these things combined make an aluminum dock from Alumi-Span up to 35% stronger than similar looking systems. And yes, they actually tested them!
