### How far can a triple 2x6 beam span?

For normal deck loads, a triple 2x6 beam over a span of **10' feet** should be enough. The maximum span is 9' feet for a single 2x6 #2btr yellow pine.

### 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 much weight will a 6x6 post hold?

A 6x6 with 12' span can support **2000 lbs.** if you assume a conservative 1400psi bending stress. If you do a good job bonding the two members together, your double 6x6 can support more than 4,000 lbs.

### Can a 2x6 span 12 feet?

The maximum distance a 2×6 can span, according to the 2018 IRC, for a floor joist, is **12'-6”**, ceiling joist 20'-8”, rafter 18'-0”, deck board 24”, deck joist 9'-11”, deck beam 8'-3”, and 6'-1” as for header. Always check the codes for determining factors or consult a Structural Engineer.

### 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.

### Are two 2x6 stronger than a 2x8?

In bending, a joist composed of two 2x6's (true dimension 1.

### Are 6x6 fence posts better than 4x4?

The standard is 4x4. **6x6 posts make it look more substantial** if you do it as a privacy fence. You can use 6x6's if you're doing a "good neighbour" style fence. ...

### 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.

### How big is a 2x6 post in inches?

Just remember that 3 2x6s is actually going to be 4.

### Are there really 2x6's instead of 6's?

They are actually a true 6"x6" post too and they are not usually just 2x6's glued and spiked -they are milled lumber glued spiked and then ran through a jointer to finish the outer dimension.

### 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.
