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.
Floor Load Capacity Table
- psf = Pounds Per Square Foot, meaning the maximum allowable weight in a one square foot area
- All floor joists supported by 4×6 skids on 8ft OC max spacing. Skids are supported by concrete block piers or similar.
- To get Total Floor Load, multiply building square footage by figure above. Example: A 10×20 size with 20 psf would be capable of holding 4000 total pounds, spread out so as to not exceed the Point Load.
- Floors may be capable of supporting more but may cause sagging or settling that would not be covered under warranty
- Total of Point Loads may not exceed Total Floor Load
- Doubling the layers of floor decking will double the point load, but not the total floor load.
- Point loads shown are based on the allowable shear strength of the plywood floor sheathing and to minimize sagging of the floor sheathing between the floor joists.
