What force can a 2x6 use?
People also ask: What is stronger, 4x6 or 2x6?
The theory is that a 4x6 joint will be stronger than a 2x6 doubled joist, but it depends on the inherent weaknesses of each piece of lumber. #2 lumber can have nasty spike knots or large round knots that are not so tight.
Are two 2x6's stronger than one 2x8? A joist made up of two 2x6's (true dimensions 1.5 inches x 5.8 inches) is slightly stronger than one 2x8 true dimension 1.5 inches by 7.25.
How far can you stretch a 2x6 with no support?
In general, joists placed 16 inches apart on the center can span 1.5 feet more than their depth in inches. A 2x8 can span up to 12 feet, a 2x10 can reach 15 feet, and a 2x12 to 18 foot.
