Can you use 2 2×4 instead of 4×4?

Granted 4x4s when used vertically are still rather strong for most applications, but should never be used horizontally for something structural. Also remember and remind yourself (repeatedly, if need be … ) that two 2×4 is NOT dimensionally the same as a 4×4. In this case, two 2x does NOT equal a 4x.

Are 3 2×6’s as strong as a 6×6 post?

One 6×6 will be 22% stronger than three 2×6’s. This assumes, of course, that the long side of the thinner boards is vertical, and that we’re talking standard dimensional lumber where a 2×8 is really 1.5×7. 5, etc. Beam bending strength is proportional to the width of the beam, but to the cube of the height.

How much weight can a 4×6 hold?

about 105 lbs.2 and better (no loose or missing knotholes), then a 4×6 spanning 18′ will support about 105 lbs. loaded at the mid-span (slightly higher if it’s loaded at third points or further from the center point).

Is a 4×4 strong enough for a swing set?

Yes, a 4×4 that is 20′ long will work. A 4×4 that is 12′ long will support about 4,000 lbs. … The metal braces look strong enough, (those are fillet welds which will hold about 1,000 lbs. per inch), but the entire swing set will want to “parallelogram” on you (with enough force).

How deep should a swing set post be?

Use an auger to dig a hole for each of the posts. Make sure to dig the holes deep enough; for this project, the crew digs holes 3 feet deep and 12 to 18 inches wide.

How much vertical weight can a 4×4 hold?

With the post in the vertical position, total height of 9 feet it is estimated to be around 5000 lbs with a perfect weight repartitions on both 4×4 ends. This does not allow for twist and side loads for posts above 4 ft. if you are building a deck or shed.

How much weight can a pressure treated 4×4 hold horizontally?

How much weight can a 4×4 beam support horizontally? In general, a 2×4 wooden beam can support the weight up to a ton horizontally, and thus, a wooden beam of 4×4 can easily support double of the weight mentioned above horizontally.

Should I use 4×4 or 6×6 for pergola?

For a very small pergola with only 4 to 6 feet between posts, 4×4 supports will work. For anything larger, though, the 6×6 stock will not only offer a beefier look and greater carrying capacity, but 6×6 also resists the twisting associated with the more spindly 4x4s.

How much weight can a pressure treated 6×6 hold?

If you assume a conservative 1400psi allowable bending stress, a single 6×6 with 12′ span can support about 2000 lbs. So your double 6×6 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 long can you get a 4×4 post?

How long a PT 4X4 lasts in the ground is dependent on where you live, your environment. Basically, It won’t last more than half a decade. I’ve seen treated posts that were under a roof last 40 years. Untreated wood lasts one year, max.

A 4×6 will be stronger, as it’s actual dimensions are 3 1/2 x 5 1/2. two 2×6’s would total 3 x 5 1/2, which is approximately 15% less cross-sectional area.
