Decking Material List & Cost Comparison for a 12 x 10 Foot Deck
The following is material list that will enable you to construct a simple 12-foot-wide by 10-foot-deep deck. Your situation may require some specialized hardware, however, this list will get you 98% of the way.
The deck in question sits only several feet off the ground. If yours is higher, you may require longer posts to reach the ground.
6x6s Baby – The Only Post To Use
I prefer to use 6×6 posts instead of 4x4s. Six x six posts allow you to create a notch so the beams rest on a wood ledge. I then through bolt the beams through the remaining 3 inches or so of lumber that is left of the post.
The diagram below is a side view of a beam as it runs over the 6×6. If you build it this way, the floor joists sit on top of the two beams.
Free & Fast Bids
If you choose to keep the beam in the same plane as the joists, you would make a 3 inch deep singular notch in the 6×6. The two beam boards would end up side by side. This would allow joist hanger nails to penetrate both beams.
Material List & Prices (Cincinnati Prices – August, 1996)
Yes, I left in the prices for 1996 to show those in the future what lumber used to cost! It gives you an appreciation for inflation.
