Dock decking replacement
 

I am looking for input on what people have had good results with what product they have used in replacing their dock deck.

I think the choices are somewhat dependent on whether it is permanent or removed each season.

Aluminum for structural design/support strength and long life together with the DECK made with real natural LUMBER milled from a TREE such as mahogany, locust, cedar, cypress, or the #1 most used deck material, pressure treated PINE.

Lumber can always get sanded, stained or painted and will look totally excellent for years and years.

Have you walked the .3-mile X 6'-wide long dock on the Laverack Nature Trail out behind the Meredith Village Savings Bank ..... www.youtube.com/watch?v=X2EqbiTpUXE ..... made with LOCUST lumber from South Carolina ..... and is totally not stained or painted ...... and two years, new!

It is a permanent crib dock

My preference is to use pressure treated would for the decks, regardless of it being a season or permanent dock, I also recommend make the deck in removable sections....

Sections can be removed and brought on shore for cleaning etc.

At the end of the day, I have had very good luck, with pressure treated decking on my dock, every few years you hit it with a pressure washer and it cleans right up nice....

PT is heavy for a removable dock.

It would work on a permanent.

Just replace my first PT 5/4 board for rot on my crib dock after 20+ years. Pressure washed a couple of times over that span. That said, I’d go with PT durability & cost.

Modern ACQ will not last as long as the older PT.
It really would be about proper prep and care to lengthen its lifespan.
