The Decks I Designed and Built were Always Set on 16" Center.
2 x 6 Pressure Treated Joist Framing System Was The Standard.
The Upright Posts & Supports were .40 Grade
(In The Ground Use) Pressure Treated 4 x 4 Inch Stock.
These Post Go Through The Frame And Are One Solid Piece
You Could Literally, Drive A
Small Truck On These Decks,
However I don't Recommend This
It Would Probably Leave
Unsightly Tire Marks On The Beautiful Decking.
These Past Project pages
are for reference only
to show customers the experience
I've had working with wood
and other various materials.
I am not building decks at this time.
