Is 2 2x6 or 1 4x6 stronger?

A 4x6 joist is theoretically stronger than a doubled 2x6 joist because it's 1/2" thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).

What is the strength of a 6x6 post?

If you assume a conservative 1400psi allowable bending stress, a single 6x6 with 12' span can support about 2000 lbs. So your double 6x6 can support at least 4000 lbs (possibly more if you do a good job bonding the two members together so that there's no slip between the faces).

How far can a 6x6 beam span without support?

What is the maximum span for a 6x6 beam? Each 6x6 beam only spans 12 feet, of which 2 of those feet are supported by a knee brace. So technically the beams only span 10ft.

How far can a 2x6 span?

2-grade 2×6 joists can span up to 10 feet 9 inches from beam to beam when spaced the standard 16 inches apart with a maximum live load of 30 inches per square foot. In comparison, No. -1 grade lumber can span slightly further to 10 feet 11 inches under the same parameters.

Should I use 4x4 or 6x6 deck posts?

Unfortunately, a 4×4 post may not be able to withstand the weight, causing the entire porch to buckle. A 6×6 post gives you a little more long-term stability, particularly in those colder climates. Not only does it perform better when carrying heavier loads, but it also makes the heading for your roof more secure.

What makes a 6 by 6 post stronger?

Posts cut from the center of the tree are stronger than posts without a centered grain pattern. To check for heartwood look at the end of the post. The closer the concentric pattern is to the center of the post, the stronger the 6-by-6. The higher the density of circles per inch, the stronger the wood.

Which is stronger 2x6 or 4x4?

But by comparison, a 2x6 would have more vertical support than a 4x4. The single 2x6 is 68% stronger than the 4x4 for vertical loads as you describe.
