We start our buildings with 4″ x 6″ pressure treated notched skids.
Floor joists are pressure treated 2″ x 4″ , spaced 16″ on center and are set into the notched skids to prevent any twisting. 12″ on center and 2″ x 6″ floor joists upgrades are available.
Floor decking is 5/8″ inch tongue & groove plywood flooring. Thicker 3/4″ flooring is also available.
