By using different sizes of lumber you can build the post to any dimension you require.
Building your own laminated posts useing 2 x 6 lumber.
The beams will be three ply pressure treated sp number two 2 by 12s using 12 foot long lumber cut to fit the distances between the supporting posts.

I m building a ground level deck maximum 24 inches above the ground it s l shaped and it ll have two long beams.
Most stock beams widths for residential construction include 3 1 8 3 1 2 5 1 8 5 1 2 and 6 3 4 inches.
It is also relatively easy to find stick glulam beams available in i joist compatible depths.
About 10 apart in a grid.
To compare built up wood beams i multiply beam width by beam depth squared and then i divide the product by 6.
The moment resisting ability of a wood member is calculated from fb x cd duration of load 1 6 for wind x cm 0 85 wet service factor for dimensional lumber x cr repetitive member factor for 3 members.
There s nothing inherently wrong with building up a 6x6 column out of four 2x6s as long as you can keep water out.
It will exceed load ratings for a solid 6 x 6 because of the varying grain of the separate members.
Another consideration to keep in mind when you are specifying a beam is its resistance to bending.
This procedure produces an 10 foot long 8 by 8 laminated post.
Shop quality framing posts and columns and save big on your construction project with menards.
If you re using glulam for nonresidential applications you can also have custom members made.
A triple 2 10 beam has a bending resistance factor of 64 2.

In fact there may be a few advantages.
Can i use rough saw lumber full dimension 2 x6 to laminate a 6x6 post.
One is 27 and a half feet the other one is 31 feet.
Use 6x6 s 4x4 s are too flimsy and almost instantly twist and split in the sun.
Add to list click to add item 2 x 6 laminated 4 ply column 2400 msr to your list.
Add plywood between the 2x10s and the factor increases 15 to 73 7.
In woeste s testing three ply 2 6 2 dense syp nail laminated posts were compared in strength to 6 6 2 syp solid sawn columns.
Be your own.
Q instead of supporting decks with treated 6x6 posts is it okay to assemble support columns using four treated 2x6s instead.
Post frame laminated columns.
