### 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. You should be fine with triple 2x6.

### What is the strength of a 6x6 post?

As this screencap from it will tell you, a 6x6 post can **support 20,000 even when 12' high**—if cross-braced and secured properly.

### 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).

### How much stronger is a 6x6 than a 4x4?

The load capacity of a 3-foot #2 grade 4×4 is 17,426 pounds, and a similar 6×6 is **20,834 pounds** or 16% better. However, an 8-foot 4×4 supports 6468-pounds and 2339-pounds at 14-feet, while a 6×0-pounds respectively – or 64% and 78% more load capacity.

### How far can a triple 2x6 beam span without support?

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.

### What size lumber can span 20 feet?

For 20-foot spans, the wood beam has to **be at least 18 inches in depth**. There are online calculators available to help when it comes to determining what size beams are required for specific spans. How Far Can a 2 x 8 Beam Span Without Support?

### How far can a 6x6 beam span without support?

What is the maximum span of a 6x6 beam? Each 6x6 beam only spans **12 feet**, with 2 of those feet supported by a toggle. So technically, the rafters only extend 10 feet.

### Can I use a 6x6 as a deck beam?

First, the IRC only allows certain dimensional lumber to be used for deck beams. In the past, 4x4s and 6×6 lumber could serve as beams, that is no longer the case. You must use **2x material bolted together** to create a deck beam, or use metal or engineered lumber.

### Is a 4x6 as strong as a 6x6 post?

As long as you are talking about comparing posts with the same species of wood, then no, **a 4x6 post is not as strong as a 6x6 post**. A 4x6 is just a 6x6 with a third of the material cut away.

### How far can a 2x6 span without support?

A 2×6 can support up to 50 pounds per square foot of weight without sagging with a maximum span of **about 12 feet when spanning a distance horizontally**, with the 2×6 standing in a vertical position. This number includes both live and dead weight.

### Which is stronger a 6x6 post or a built up post?

**A**. Frank Woeste, P.E., professor of wood construction and engineering at Virginia Tech, responds: The built-up**post**you describe may be**as strong as**the**6x6**, depending upon the grade and species of the lumber, and how the 2x6s**are**nailed together.

### Which is stronger a solid 6x6 or a triple 2x6?

- The
**S**and I of**a**solid**6x6**beam**are**both 22% greater than that of**a**triple**2x6**'**s**simply because the solid beam is 22% wider. However, the fiber strength in bending (Fb) of the triple**2x6**'**s**is allowed to be multiplied by**a**"Repetitive Member Factor" (Cr) of 1.15.

### Which is stronger a 5x6 solid beam or a 2x6 built up beam?

**A**5x6 solid beam is weaker than**a**triple**2X6**built-up beam with the same exterior dimensions but that is not true for**a 6x6**vs triple**2x6**'**s**although the difference is not great. The resistance to bending Moment (M) of**a**beam is equal to its Fiber strength in Bending (Fb) times its Section modulus (**S**).

### Which is stronger solid post or multiple studs?

- We've found that the (
**3**)**2x6**ends up being**a**stronger column in most cases even though it is smaller because when you go to**a 6x6**we specify**a Post**and Timber Grade of lumber**as**opposed to the 2-4 grade for the studs, and the PT grade has mostly weaker design values. RE: Solid**Post**or Multiple Studs?
