Building a 10x24 garage/shed. Putting it on 4x4’s so it can be put on a trailer to be moved in the future but the longest 4x4’s I can find are 16’ long. What is the best way to secure a 16’ and 8’ beam so it can be drug “dragged” onto a trailer?

I am planning on building a 24x24 portable building. I'm not building a floor just make the bottom plate strong enough to sit directly on the ground. I want to use 3 1/2" oil well pipe. Strong, won't rot, and it's fairly cheap. It's 30' long so no need for any splices. Also you can weld it

6x6s would help a lot.
12x24 would make better use of material.

6x6 would be much better on a shed this size, and I'd just do a big lap joint (bolted) to get the length needed. The 6" gives a lot more "meat" to cut an angle in the ends, which will help get it in the trailer.

10' makes sense, as I think that avoids an oversized permit for transport

I believe that the "shed" builders use the wall structure design as more of the strength needed during loading/unloading than the 4x4 base.
I think that there's a standard spread/layout for these so that it matches the modern shed trailers "track" and support that I would find out first. They're more "runners" than structural support, a common Pt SYP 4x4 really doesn't have much strength.
Stagger your joints on your 4x4's is about all you can do.

I built a 4x16 in two parts (based on a 4x8 sheet of plywood as the floor) and then attached them. i can separate the halve if needed (the roof shingles would be the hardest part0.

On our sheds over 16’ we laminate four 2x6pt for the two main skids in the center and laminate two 2x6pt for the skids under the side walls. Put the center skids 5’ on center so that the building will slide onto a shed trailer. Anything over 8’-6” requires an oversized permit.

I like PC's idea with a little twist, instead of a Lap Joint side by side with a 4 to 5' overlap bolted together
with several carriage bolts, A 45 degree angle cut on all 4 leading edges to avoid any snags while loading.
Biggest reason for me is I would probally screw that Lap Joint up. Around here putting skids under a shed type
building makes it a portable building and not taxed as permanant structure.

Sounds like redhead is in the industry and I'd pay attention to this information. 👍

He should be able to find 20’ 6x6s.
Depending on where this shed will live, you could fasten up some 2x6s but if its not a very dry place they will rot faster than a solid beam.

This is a tool buying opportunity you simply must get a WOODMIZER saw mill and 8”x 8” x 24’ runners.

This type of mill is pretty common hobby you could likely find some one to make them for very little money.

Apparently a 3" runner is standard if the op wants a shed guy to move it. See post #12
Not many folks worried about making a relatively small building portable has the trucks and equipment to load and move something this bulky.
Those shed trailers are close to $100k with all the hydraulic functions, then there's a $100k +/- truck to pull it!
Building a "portable" building must consider the standard requirements of the specialized equipment it takes to move it.

There are specialized shed trailers and mules, but if it fits, it can also be dragged up onto a roll back

I don't think a typical Woodmizer isn't handling 24fters without sliding the log a ton of times.

Would need a bed extension, I think std LT40 can do 20ft... and that's a $50k+ mill. Mmore now in sure, that is 2010s pricing)

Lt10 is good for 10 or 12ft.

Shed places here just use a roll back tow truck.

I built a 8x16 shed years back that I had moved to the house I am in now. Shed was about 5 years old when I had it moved. I ran lags down through the floor joist into the 4x4s to secure them. I did every other floor joist IIRC. One lesson learned is to space your skids an appropriate distance apart. They use specialized trailers for hauling sheds, the trailers have rails spaced a set distance apart for the skids to land on. The trailer also has short straps that strap over the skids on each rail, meaning the skids can not be at the outer edge of the building. The hauler and I were able to make it work, but it was a headache.

Long story short, go to a shed seller company and measure how far apart the skids are. Also, I think the shed companies use 4x6s for the skids.
