Is 3 4 Plywood Enough To Hold A Floor

A 12 by 36 inch piece of 3 4 inch fir plywood can support up to 50 lbs.

Is 3 4 plywood enough to hold a floor.

It last me for years and through 3 moves i was military at the time. This is so the fasteners don t go through the back and puncture the plastic sheeting between the slab and the plywood. I would use 4 x 4 s or doubled up 2 x 4 s since that would be cheaper tahn 4x4 s for the corner posts. Under the deck were two 1 2 inch plywood crosses plywood cut 1 2 way at the center so locked two 3 long pieces of plywood.

If you look at old bank barns you will see people parked tractors and trucks inside. 2x4 and 3 4 plywood will not handle that load. A plywood subfloor generally uses 1 2 inch to 3 4 inch thick sheets of plywood that have one rough side which faces down and one smooth side which faces up. The bamboo install instructions say that 3 4 plywood is sufficient to support the floor.

Then use a brace 6 10 from the floor the lower the better in the corners where the braces attach which should be 2 x 4 s you want to notch the 4 x 4 posts so the 2 x 4 s fit flush. They use real 2 or wider lumber for joists and often 10 12 deep. Floor was 2x4 pt joists 12 oc. Load is 2000 pound per square foot.

The sheets are generally 4 x 8 or 4 x 12 feet in size. The load it can hold usually depends on how much support it receives from adjacent wooden members. The owner of the sales lot had his bugatti parked in it when i checked it out. He has sold these buildings now for years and years.

Those joists are covered by full 2 or 3 thick 2x8 or 2x10s. However one room has solid oak in it and it appears to be sitting on a 3 8 plywood underlayment. Nwfa specifies 1 5 to 2 fasteners for 3 4 solid strip and plank. Osb oriented strand board.

So a total of four 3 foot plywood boards. The floor was surprisingly flat and took only a small amount of sanding shimming. Use the alternating glued veneer layers of 3 4 inch plywood make it stronger than solid wood. Bank barn is a barn built in the side of a hill.

The framing was 1 2 inch plywood deck. The deck was 3 4 pt plywood. The floor held the tire weight with no signs of strain. The reason for the allowance of 1 5 fasteners is for 3 4 plywood directly over a concrete slab.
