Hereof, is a 2x4 stronger than a 2x6?
Yes, a 2x4 is stroger than a 2x3 as is a 2x6 stronger than a 2x4, but using one over the other does not necessarily make the structure stronger, it just may be overkill.
One may also ask, are two 2x6 stronger than a 2x8? In bending, a joist composed of two 2x6's (true dimension 1.5 inches x 5.5 inches) are slightly stronger than a single 2x8 true dimensions 1.5 inches by 7.25 inches.
Consequently, how far can you span a double 2x6?
|Douglas Fir-Larch, Hem-Fir, Spruce-Pine-Fir, Redwood, Cedars, Ponderosa Pine, Red Pine||3X6 OR 2-2X6||5'-2"|
|3X8 OR 2-2X8||6'-7"|
|3X10 OR 2-2X10||8'-1"|
|3X12 OR 2-2X12||9'-5"|
What is stronger a 4x4 or 2 2x4?
Now, I knew two 2x4s sistered would be stronger than a 4x4 since you have opposing grains, what I didn't realize is that 4x4s are actually cut from the core of the tree which is the weakest part of the tree (thanks Dad for the lesson in lumber). So a standard 4x4 is actually much weaker than two 2x4s side by side.
