Which is stronger 2×6 or 4×4?

The single 2×6 is 68% stronger than the 4×4 for vertical loads as you describe. However, I caution you that it may be a good idea to have someone design this beam properly so the job is done right. If you’re willing to have a 4″ wide beam, why not create a double 2×6 beam, this will be 237% stronger!

What is stronger 4×6 or 2 2×6?

A 4×6 joist is theoretically stronger than a doubled 2×6 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).
