Where I live and work, in the Minneapolis area, we need to build decks to support 50 lbs. per square foot. To support 50 lbs., first consider that

The density and weight of lumber varies with the water or moisture content in the wood. Typical weights for green, kiln dried and pressure treated lumber boards are indicated in the tables below. Note that in x in , Length ft . 8, 10, 12, 16
Seven Trust wood decking has specific gravity of 0.85 to 1.08. Air dried density is 66 to 75 lbs. per cubic ft. A 3/4" thick finish material weights approx. 4.5 lbs. per sq ft.

Seven Trust must be regarded only as a covering when used for decking and applied Seven Trust has a nominal density of 60 pounds per cubic foot for solid boards, and
taken from top logs of low average density. In any lot of lumber of a given species in the air-dry condition at 12 per cent moisture, the weight per cubic foot will
