W-Beam Post or 6x6 post..


I believe a 6x6 post can only have a maximum height of 14'. I need something near 16'. Instead of using a pressure tread 6x6 post, could I use a W-Beam? Any recommendations regarding to the appropriate size? Thank you.

If you are needing a post of that length, you would be a fool not to consult with an engineer

I'll only need it on one corner of a 9'x12' patio. I can support the patio along a preexisting 12" thick reinforced concrete wall except on one end. I plan on using 2-2x12 beams. If anything I'm over-designing. I don't mind over-designing when it comes to the steel beam too.

Are you building a deck or a patio? If you are building a deck, what code are you designing to? Your post is so vague I can't tell what it is you are trying to accomplish, and I don't understand your basis for concluding that a 6x6 post is limited to 14 feet. Are you concerned about buckling, or did you read about the 14 foot limit in a local code book, or perhaps in an on-line article?

I'm building to NY code. What I'm building is a patio that adjoins to my house and reaches to my deck that is 9' away. Yes, I did read online that 6x6 posts can have a max height of 14' according to certain code. Not sure about NY, but either way I feel more comfortable using steel for such a height. Possibly a 1/4" thick, 5-1/2" diameter steel column. I would have the shop weld a 1/4" plate to the bottom of the column for the footing and a 1/4" steel U-Channel Flange at the top to accommodate the 2-2x12's or possible 3-2x12's.

Post a picture of the area. What you've posted doesn't really seem to explain the situation.

for what it's worth ....

According to publication by the American Forest & Paper Association a 6x6 douglas fir No. 2 wood column at 14' can handle 120 square feet of tributary load (when rated for 60 psf total load). at 17' it is rated for 84 square feet of tributary load.

Hopefully you are no where close to the ocean or salt water.

make sure you're steel column is galvanized or coated if exposed to weather.

You could always brace the 6x6 wood post in 2 directions with a knee brace. It should allow you to increase the length a couple feet.

However, If I was in need of a 16' high post, I'd definitely be in contact with an engineer.
