Has anyone ever worked on a project involving shipping containers? I have a potential project that will involve stacking a series of these to create a building. There will be openings that are cut into the walls. I'm curious about how these are framed and if anyone has any other pitfalls to watch out for.

Someone from Christchurch NZ, where they used containers for years as temporary shops.

Get the specifications from the ISO list.

Assume NOTHING more than the absolute minimum of any thickness, length or weld quality. Certainly, "some" are better than minimum, but don't bet that way.

I don't like the idea because the shape of the walls and hollow areas between containers are natural food traps and rat/vermin nests on the accumulated debris that human's throw in the crevices.

Remember that there are engineered and constructed to standards.

if YOU cut holes in them, YOU are responsible.

Are they new, or used? There's been some movement to re-purpose used shipping containers for various applications.

Pitfalls? I have never used one of these on a job, so I can't say for sure.

I watched an NASCC presentation on these this past spring. Mostly, I was thinking that it's hard enough to coordinate with architectural when I'm NOT stuck with an 8 ft module! The whole idea seemed asinine to me. However, if people are making money by designing safe structures with them, then more power to 'em.

I recall reading long long ago of hippie efforts to build geodesic domes from the roofs of old cars, and it was pointed out then, that much of the cost of a house is in the foundation, piping, electrical, heating/AC, windows, etc., so if you come up with a free "frame", you don't save that much.

And I've read of people wanting to repurpose old school buses, which are cheap enough. But one problem is, they're generally not insulated, not tall enough, just not made to use as RVs, etc.

With the containers, I will point out that if they need to be recoated, with a regular abrasive blast and heavy duty coatings, that is expensive. So factor that into the building and maintenance cost.

Assuming you are not using these right next to the shipyard they come from, you'll run into a pretty good chunk of change hauling them and unloading/placing them as well.

You may have a lot of strength in these things, but trying to show that if you don't have mechanical properties, material certificates, etc., may be a challenge.

There was just an article of containers being used for a house in Brandon, Manitoba, Canada... a classy looking house... but, there was no cost savings in the article. House cost $500,000. I can't see that, myself.

I had a client that used them for 'blast' resistant office space at a chemical plant.

A few quick thoughts:

1. Definitely find and watch the presentation from Dr. Ioannides from NASCC.
2. Before modification these things are very strong. The sides essentially work compositely with the top and bottom rails.
3. These routinely see higher loads than any earthquake ground motion could cause while in transport on ships.
4. As soon as you cut holes in them #2 goes out the window (see #1).
5. You need to think about sequencing and access to attach the modules together. You may end up with a lot of blind connections and tricky spots as they get stacked and oriented.

Seems like you would need prior approval from the building official. More specifically, what is the lateral resisting system....some concoction of stacked shear wall system? I buy the shear wall analogy but I have not seen any information of corrugated steel plate shear walls. AISC has a design guide for steel plate shear walls, but I think that would be a stretch.

The huge problem I see here is getting it permitted. I had a client seriously approach me about this last year; a month or so later he said the meeting with the city was about 5 minutes and they basically laughed him out of there. I know it can be done but there is alot more going on then just a steel box and I dont think its worth the time and headaches to make it happen at least here in our area. They all look great on HGTV tho.....

Complete Guide to Shipping Container Framing

If you&#;ve ever built a wooden structure, you probably know all about frames. These rigid members impart support and shape to traditional structures. The heavy-duty steel body of a container, however, offers adequate support and does not require interior framing. Instead, shipping container frames help you attach drywall, spray foam insulation, or make extra doors and windows. 

The application isn&#;t the only thing that changes when you apply frames to container walls; the process also varies. Below, we&#;ll walk you through how to attach frames to shipping containers, the different types available, and the various purposes they serve. 


How Do You Frame a Shipping Container?

You can add framing to your container by selecting a suitable design and installation method.

Consider an appropriate design, and secure the base plate to the floor and ceiling with angle brackets. Refer to the steps below if you're planning on adding frames to your shipping container homes yourself.

 

Step 1: Select an Appropriate Material

First, you need to determine which material you're using - wood, steel, or aluminum framing. We've covered the advantages and disadvantages of each material for internal framing in the subsequent section.

 


Step 2: Finalize the Design and Layout

Here you'll probably need professional help. You will also have to determine a layout that appropriately houses the electrical fixtures, accessories, plumbing lines, and other outlets.

If you're using frames to add insulation, you'll need suitable segments that close all underlying air gaps. Building codes and standards can help you determine the size and width of frames that you'll require.


Step 3: Assembling the Framing

Securing the frames in their positions can be a bit tricky. If you attach the frame directly to the shipping container wall using nails and screws, it may cause leakages.

Such gaps can affect the wind and water-tight capabilities of a container, leading to condensation and moisture build-up.

As a preventative measure, you should make sure there is at least a 1" gap between the frame and the walls.

Start by placing the frame in an accurate position. Use pocket-hole joinery or toe-nailing to secure the vertical beams with the horizontal base plate. Fix the horizontal ceiling beam with the vertical beams using hurricane ties. You'll have a single assembly ready for installation in your container office or home.

 

Step 4: Installing the Frame

Secure the base of the framing to the floor using screws. Ensure that you appropriately space them out to avoid any unwanted movement. Use angle brackets or D-ring tie-downs to secure the top section of the framing. The frame should now be ready for use.


Different Types of Frames for Shipping Containers

You can either use wood or metal for framing your shipping container home. Metal framing can come in either steel or aluminum.

Each type offers its unique set of pros and cons that make it suitable for specific applications.


Wooden Frames

Wood is one of the most widely used materials for framing, which is why you're likely to find more resources and help for building wooden frames.
 

 


Advantages of Wood

  • Wood is a natural insulator. It acts as an excellent thermal barrier in extreme cold.
  • Cutting and framing wood usually takes less time because it does not require heavy tools.
  • Since wooden framing is quite popular, you can easily find contractors, designers, and the workforce with experience working with wood.

 
Problems with Wood

  • Wood can rot with time.
  • Wooden framing can attract termites and other insects.
  • These frames have lower strength than metal. Therefore, they form bulkier structures with more components.
  • A wooden frame can easily catch fire and present additional hazards.


Metal Frames

While some prefer steel to build homes, others recommend using aluminum to create frames of ideal thickness. Below are a few factors to consider while using metal framing for your container home.

Advantages of Metal

  • Steel and aluminum are more robust and provide more structural stability.
  • Because they require fewer members, their designs are relatively more straightforward.
  • There is less potential for a fire hazard.
  • Your framing is safe from insects, termites, and fungus.

 
Problems with Metal

  • Metals are good conductors of heat, but instead of containing that warmth, they make it difficult to insulate your walls.
  • Welding aluminum requires complex machinery and skilled expertise.
  • Metal framing is prone to rust which can impair its functionality.

Typical Uses of Shipping Container Frames

  • Framing is a prerequisite for insulating your shipping container home. You can add spray foam or fiberglass panels to retain warmth in your container.
  • Frames can act as support beams for additional doors and windows.
  • You can conceal your electric lines, plumbing, and other utilities behind a plywood-framed wall.
  • A steel frame can add more structural integrity to your containers.

 
Conclusion

Shipping container frames can help you add insulated walls, fill air gaps, and make design modifications to your structure. Depending on your level of comfort and expertise, you can select wooden or metal framing. 

Because framing requires immense labor and skills, it is always best to consult an expert before modifying your shipping container building.

FAQs

Do Shipping Containers Need Insulation?

Shipping containers may require insulation, depending on your location. The metal structure doesn&#;t contain heat very well and easily allows cold in. 

Can I Screw Into a Shipping Container?

Although you can screw into a container's wall, drilling can cause leakages. Such gaps can affect the container's wind and water-tight abilities.
