Thru Flow® decking panels are both a safe and environmentally friendly. they are an ideal decking surface due load bearing and anti-slip qualities. thru flow panels are also well liked by environmental protection agencies, due its construction and non-light impeding and non-leeching design.

Thru Flow® is also a great decking for docks that are in areas with large amounts of wind and waves. the grate style surface allows both water and wind to pass through the dock. these type of conditions can move, flip or even destroy other docks. The aluminum stringers provide a rigid support and added durability for this vinyl dock system, and are constructed to be used in conjunction with any of the max dock supports.

Freestanding dock supports for this system can be found here.

Frequently Asked Questions
Question:How do you install a corner section - Michael (05/20/2013)
Response:It is designed to work on 4' wide MAX Standard dock sections. It comes standard with three triangle hanger brackets and attaching hardware. The three brackets attach on the under-side of the lip on thestinger extrusion, one on each end of the triangle stringer and one on either corner of triangle. The bottom bolts tighten against the bottom of stringers and the longer bolt presses hanger brackets together sandwiching the dock triangle and dock section stringers together. Triangles have machined ends with hidden machined corner blocks, so corners are bolted solid in lieu of welding. This allows for stringer to be removed in case of deck panel damage for replacement.
