Storage: Dry Van vs shipping container

[Wis Bang]

I didn't think that the outside walls were double walls but they are corrugated inside and out. This is certainly stronger than a flat plate wall but I don' think it is the same as double wall.

Look at the original vents [small perforations in one section] in the sidewall and then examine the same spot inside...you won't see the holes...the corregations are staggered between the two walls, you can feel the difference if you stand near the door and feel inside and outside at the same time.

This is how they can be the bottom of a stack 10 - 12 loaded containers high on the ship. When you see the stack above deck, you don't see the ones stacked below out of sight. If they were single walled they would buckle. I've had loaded units rolled and as long as the front corner doesn't dig in the sides just get scratched up.

BTW 'corten' steel is the best, the box should be marked that it it made from that.

No wheel on these. They look almost like shipping containers. I saw an ad that looks like this.

I saw those last week! (Mervyn's boxes, removed from trucks). In West Sacramento near the CHP Academy.

A standard dry shipping container is a single thickness wall.

I work on shipping container boxes every day in some form or fashion.

The sides of the unit don't support anything, 100% of the weight is on the corner posts.

All ships have water tight deck plates. Above deck containers sit on these plates, they do not sit on the below deck containers.

I usually drag my camera with me when I have to go aboard.

I had two 40 ft containers and my brother has one right now. I've drilled into all three of them, and cut out sections of mine and my brothers. The sides are single wall. Here is a picture of a section that I cut out of a container to make room for an entertainment center.

Sorry, WE have a 20 footer for records storage that is double, maybe our repair guys did that as the shelving is bolted to the interior and does not show on the outside. Our sister company does repairs w/ ILA labor off the pier and buys salvage units they fix up and sell. The entire repair shop support, locker room, parts even the welders & air compressor are made from containers...the guys work outside year round 'cause when we were in the port the owner wouldn't build a building as it would eventually end up in the pirt authorities hands...

I have seen one 40 that is double, it was a lease unit that my company returned for ACL from off-lease to the depot that ended up at our Motorcycle club; I ran the number in our computer after the club got it for free for storage. It was not a refer either...

I ASSumed they all were, my bad!

I have a ton of pictures on my work computer including some of the stuff adrift after Katrina & ships, post storms, with missing units and tipped rows. They are tough units.

Willl: Thanks for those shipboard pictures. Containers and the way they are handled are an amazing thing to me. I know boxes are up to 53' now and I just wonder how long it will be before they become wider. I know the issue with how wide they are is due to being trucked, but mobile homes are also trucked and I'd think some shipments of speciality items would be worth having the "Wide Load" banners and escort vehicles. The snag would surely be that all the equipment is made to handle the smaller boxes. Even the 53' boxes still have the braces and lift points at the same location as the 40' boxes. Do you know how they handle these aboard ship? Are they always the top box on the stack?

I'd love to spend a day just watching a container ship load and unload. I'd pay to do it. They could call it "container ship tourism."

On the subject of double-wall containers. I know they have refrigerated containers. Are those not double-wall?

Maybe some of these are for sale cheap!

Any container over 40' must go above deck. 45' and above aren't necessarily left for the top, I've seen them in the middle of a stack but its gota be planned out.

Yes. You can also get insulated dry boxes (with or without heat) that are double walled.
