NEW KIT! - Join Two Shipping Containers Using NO WELD Brackets | DIY Pitched Roof For Home Or Garage
Вставка
- Опубліковано 19 тра 2024
- Follow along in this video as we showcase our NEW concept for connecting two or MORE 40-foot shipping containers together!
For the first time ever, Channing thinks he's found a way to safely use wood on a shipping container. It is not as easy as cutting out the center walls and pushing them together. It’s a lot more difficult than that, but we have a new concept kit that makes this process easier! And it DOESN'T REQUIRE WELDING!
This center-split container will be used as an underground mining office, but you can use a double wide sea container for many purposes. You can convert this sea can building into a container house, garage, workshop or whatever you would like to modify it into. It is a 20' x 16' OR 40' x 16' structure, so you have a lot more room to create what you want!

Thanks for the vid Container Guy. Over the last 7 years, I’ve sliced and diced dozens of containers into multi-level dwellings of many different shapes. This is my favourite way to prefab for building in remote locations.
Love this! I’ve taken down an old 60s Brunswick bowling alley, and am making portable individual bowling lanes inside conexs that can be shipped to remote locations and ran off solar. This is a great way to get more width in the sitting area.
Looks like you’re taking building with containers to the next level. I really like this. Maybe a cathedral ceiling?
Just knowing that even an old sea can can be retrofitted to become something awesome like what's presented here gives an eye opener into the possibilities that the multiple millions of available shipping containers can have in regards to the homeless problem. ... Don't let em rust!!!!💪🏻
What a great innovation. I really like that you are always candid about how an idea gets refined by your real world experience on actual orders. So many practical and cost-saving concerns are addressed by the header kit and 2-way upper decker brackets and being able to use the cut out sides as roof panels. 🎉🎉🎉
Thanks Wendy 🙏 Appreciate your feedback. Keep it coming!
This looks like a very promising concept, can't wait to see the first build.
Always learn from you folks.Thank You and Regards
Thanks for watching Rickey
Lots of incredibly smart concepts.
The genius of this will be realized in hot environments. The roof keeps the heat off and the space creates a breeze to keep it cooler. If you're trying to air-condition your setup this is worth it for energy savings alone.
Good things to come with these brackets😎
There's a Farm not too far from me and the man took two containers and made a barn out of it for horses. There were seven stalls and one tack room he surrounded it with wood and you can't tell it's made with containers now. I thought that was pretty ingenious. Yours on the other hand is awesome. I wrote this before I saw the drawing that you had with basically the same thing I just said except your drawing was way wider than his
Young bloke + Great Trade Skills + Clever Deeper Thinking = WINNING!!!
Don't let others nor yourself hold you back, knocking it well out of the park
I would never have though of recycling the side corrugations as roof. I would never have thought of spilting a container either to make that roof pitch.
Huge credit to you guys using unrestained free thinking.
Sadly I think I'm usually not easily impressed...I am after watching this video & yup I learned a lot.
Keep on keeping on
World needs more guys like you
Great ideas! Keep them coming, thank you
This is all brilliant. Can't wait to get a container structure started.
do some research. these things are a waste of money
@@samgriess438 I've done the research honey in fact I've been a highly successful contractor who does nothing would build and renovate homes for 40 years. Which is quite possibly longer than you've even been on this planet 🤣😂🤣😂😂 when they are constructed properly, with proper architectural engineering plans. They are actually one of the best forms and structurally sound homes you can build. Withstanding hurricanes and some of the most aggressive winter storms you can imagine. As well as flooding conditions.
I signed it existentially hilarious that you were so deluded as to assume that I have no idea about structural Integrity or engineering when in fact I have been doing this for forty years. LMAO b guess again oh wise and omniscient one 🤣😂🤣😂🤣😂🤣 putz
I love this channel and the products you are developing. You are the first person that I have seen that is creating brackets to solve easy connect of roof to container. Love it
5:32 We have a video on this coming out soon which will go into more detail on the brackets
I like what you guys do 😁
Another great video - can't wait until you finalize the design and it is ready for public 'consumption'. Love how you are continuing to innovate.
Very informative video Channing. I’m interested in getting something very similar to the container home project for my homestead.
Thanks Todd!
Excellent.
Great video, gives a lot of ideas, for building an outdoor garden DIY Workshop, or a combined Potting Shed and Greenhouse, or a Garden Office come Sewing and Craft Room too.
Even off Grid Solar Electric and Hot Water Panels and Wind Generation Shed, with recharging electric battery energy pack, as well as large Hot water Tanks and back up wood burning boiler unit too.
Maybe housing a domestic drinking water purification unit, working with either a rainwater capture and recycling storage tank system, or supplied by private water borehole system too.
Housing all or most of your off grid systems, in one shipping container building.
Though if you have off grid drainage and a domestic separate "Black Water" and "Grey Water" waste, capture and recycling plus treatment system, you house these in a smaller shipping container too.
Have you done shipping container conversions, along these lines at all?
I really like your innovative, solid reasoning and ideas!!
Thanks Thomas🙏
You could use a plasma cutter to split those containers. If I were you I would make a custom jig. Basically a full stick it 2"×3/8 and mount custom cut out pieces on the bottom side so that when you mount the stick on the top of the container that its flush on the metal from end to end including all the dips. Then the plasma cutter should have a drag tip thats typically 3/8 " from the tip center.
Mark the center point of the container on the ends, then set the bar 3/8 from center, then drag the plasma cutter across the container using the bar as a straight edge. If done correctly it will create a razor sharp line. Clean the edges with a grinder after its cut in half, and ta da.
First cut will take a while, however if you keep your jig you can use it many many times. So to mark the container, set up the jig, do the cut, and clean the edges will take....🤷🏼♂️ 20min or so. Depends on your workers really.
I agree it depends on who we have on staff at the time and their skillset. What about a big custom bandsaw and push the container through?
@@TheContainerGuyTV expensive. Blades would not last that long.
I make hoppers, forklift platforms, shoots, wall mounts for warehouses. Basically all large stuff. Plasma will be the quickest, and least expensive. The trick will be to get a decent plasma cutter with a long lead. They run about 4 to 6 thousand. (Depending on the brand and capacity. ) I'll send you the info on the one i use at work. It's great and i have cut half inch cold rolled with it no problem. Trust me, once you create some custom jigs to serve as a straight edge for the plasma cutter its REALLY easy to do. It will cut those containers like butter.
@@J.D.Mc. We have a nice Thermodynamics plasma cutter. The guys used to use our Milwaukee 8" metal cutting skill saw. Not sure why they used the angle grinder this time. I think because the corrugations bind the blade from the weight of the guy in the roof.
We've found the plasma sparks burn the container flooring so we needed fire blankets to prevent burning. It is especially bad at the top and bottom of the corrugations where it blows through the caulking and shoots firey balls everywhere.
@@TheContainerGuyTV mmmmm...... i see. It's a interesting dilemma no doubt about it.... I'll chat this over with my journeyman monday, spit ball some ideas back and forth. Quick question, is it possible to flip the container upside down to do the initial cutting? I'm not sure how the floors are made to be honest. If its possible then you could put down some bricks all the way around the edge keeping the container a couple inches off the ground to be able to do a clean cut. Not to mention it would be easier to set up the jig. 2 guys just walk it in and put it in place. 🤷🏼♂️ let me know if the floors are anchored down. Floors are wood right?🤔
Yep
Thanks for your consistent development in perfecting these containers! You are going to be a game changer once it's perfected!
We hope so. Lots of new developments to announce. Everything takes time though.. stay tuned!
Is there away you have to stack ne on the top
Very Impressive :)
Thank you
So many ideas! LOVE THIS!
Good episode and you got your message over quite well about currently being undecided of final design direction. I guess each location will require its own solution. I know at the recent Qatar World Cup site they used hundreds of these as airB&B bedrooms for visiting fans.
I am looking at your designs with great anticipation well thought
Awesome Sauce!!!!! Way to go boys!!!!
LOVE IT
Great ideas can't wait for the finial product.
I will keep my eye on this concept.
Most containers are fairly expensive unless heavily damage and or contaminated.
Their dimensions are not ideal as living accommodations, they can make fairly good portable offices, kitchens or ablution blocks and of course storage sheds.
They usually need special transport and site permits to be located in many residential areas.
For the roughly ten thousand dollars it will cost to simply acquire and ship a container you can buy a purpose built transportable home module of similar size already equipped with interior panels insulation wiring and even plumbing.
The last time I looked you could buy a demountable home the size of three or four containers for about $40,000 erected on site ready to move into.
The benefit is that because they’re designed as habitable structures from the start you get higher ceilings and room layouts from the get go .
The only way container homes make any sense is if you can get the containers for free.
This right here
@@SNOUTxTOUT I tried to buy one recently and wasn’t impressed with how over priced they were.
I wanted one to move house and use as a storage shed. I could have gotten one in very used condition for a reasonable price but the cost of delivery and transport was more than the cost of the container.
So I ended up just hiring movers for about half the cost, who ironically used a truck with a large container on it.
The container I wanted wasn’t available except brand new for about $12,000 . Small ones in poor shape were about $800
Transporting them was the biggest hurdle as it would have cost several thousand dollars due to the distance and other logistical issues.
This is getting close to what I designed. The "normal" roof system allows for snow and water shedding, just be sure to raise it up enough to allow outside insulation to extend past the can's roof, now an interior ceiling. Regular batts or blow in can be used between the two to save $$s. Wiring can be routed above the ceiling and dropped down into the living spaces.
Insulation is the cost driver for residential usage and I found it necessary to have both interior and exterior insulated to meet code and keep interior width. The trick was not to frame both in a conventional way and still allow drywall and vinyl siding.
I await the next video on this to see what you do to the top (folded) beams to support the roof structure.😮
You're onto it. I think spray foam on the exterior for insulation and a mineral wool interior insulation would be a perfect flash & batt system which is the best insulation system out there. Foam is the air barrier and vapour barrier. Mineral wool is a mold resistant batt for sound and added R value.
Comes down to budget. If money isn't an issue, I may have been wrong in this video in saying one side or the other needs to remain a container.
It seems like money is an issue for anyone looking for a container home. The rich live on yachts haha
@@TheContainerGuyTV well if you're doing/imagine a house for it's own person, then, it's really worth to spent at the begginning extra money to make a good build right from first try !
love the exterior brackets
so you would recommend spray foam even for exterior insulation. i guess it would be cheap to put 2" closed cell on the outside, wood frame, rockwool in the batts, and use like shiplap or fiber cement for the siding. keep the corrugation as the interior wall and you are good to go! this way would save you space on the inside.
You're pretty much 100% on track.
The foam is a good insurance policy. I'd like to try batt only but would take 5 to 10 years before we could see if it holds up or rots/molds.
The spray foam locks in the structure and will prevent excess movement. Without it, my guess is you'll see cracks in the cement board or gaps/bows in the shiplap.
I wondered why There hasn't been more about the double containers and if there could have been three or more. Now I know!. Great ideas are coming to fruition.😁
Even better ideas in the pipeline to get the costs WAY down. Stay tuned
@@TheContainerGuyTV I missed the video about attaching a standard container to a hi-cube container. I have searched and cannot find it.
Find an experience welder and they can figure out how to cut metal the best way possible. New technology is always making it easier. Keep working this container project , don't give up.
I'm doing 4 48 insulated containers so far working great.
That's awesome!
Looks like a good solution for many people
Really liked this and look forward to see what's next.
Thx for the updates.
Quite interesting and informative
Great idea.
So much information and great advice!! Thank you, Channing!
🙏
neat idea to utilize these. I have a few on my property we use as sheds but this gives me more ideas i could use them for.
great video
Have you considered using reefer cans for some of the residential builds? I worked for a major shipping company years ago used mostly reefer boxes. They built a few of their maintenance offices out of old/damaged reefer boxes. They worked great
I'd like to see some ideas using short/tall container on the inside ceiling area.
Opens it up to lots of possibilities. Could play with hidden up-lights and coffered ceilings. Maybe narrow windows up there.
Also, if support posts are needed, they are only 4' in from the side walls inside of smack dab in the middle of the room. This way will work so much better with floor plans.
Waiting to see a finished final version.
Great idea, would make for a great garage/shop option. Can't wait to see this all finalized 👍🏻🇨🇦
Thank you. Where in Canada are you?
@@TheContainerGuyTV I'm in Ontario.
SOOOOO EXPENSIVE
just build a garage ffs
I wish you guys would develop a weld in inside framing set up that would strengthen the walls and roof to allow the thing to be buried. Something like interior cross frames of the walls, and across headers to tie in to strengthen the walls and ceiling. Then the outside could be sprayed in bed liner for water proofing. This way they can be set undergroud enough to get the roof line deep enough for a slight dirt layer for grass. So many people have tried to bury one as is for underground storage and failed.
You should be able to easily find a truss manufacturer that can make you a truss for this system
Great video. Yo container guy, I have a container home I have been working on, down in Arizona, I think you are in Canada, but I chose reefer container that had stainless steel interior, exterior, and raised t flooring. Anyway, I wonder why I never see any container videos with quality like yours using reclaimed insulated containers. Is that something maybe you might have in a future video? Thanks!
I love the idea of the roof beackets; I am definitely going to purchase this as soon as it's available. I've been looking for the bridge system that connects the containers, but haven't seen them yet on the Amazon site.
Can these addon's be mobilized as a portable on-site workshop. So that the whole assemble can be de-constructed, transported and re-constructed elsewhere as needed for a contract workshop?
Great work!
Your ideas are wonderful. But living in FL. I would not want wood. Stability and termites are just some concerns. Looking forward to your next vid✌️
An insulated fire proof emergency pod with temporary oxygen supply sounds like a great idea for the flash wild fires that rip across the western US. If it was placed in an area with no vegetation around it the fire would not actually contact it but it would withstand the blowing embers until the firestorm passed?
Good stuff!
Thanks so very much!
Amazing. Intel.
Thanks for watching
Love it! I WANT SOME!
Hi, do not know much about the R factor of spray foam, as you developping a new method of framing for the roof and wall did you think of using Rockwool insulation, it is fire and water resistant you can use outside and inside.
I love mineral wool. At my lake I did a 2x8 wall with ~3" of spray foam plus mineral wool. It's around R40. Not cheap though.
We are filming a video today (pending rain) comparing fibreglass, mineral wool, spray foam, and Insofast.
Spray foam is R6-7 per inch
You’re on to something here! Earned a subscription
WOW good stuff
Great idea for the brackets you designed. I’m thinking that if you can change the bracket by having a bolt or a pin through the bracket so people can adjust the pitch of the roof depending on their needs. I think this would be more forgiving for the DIY ‘er on their projects.
Keep good going!
This is a good idea but for me in the near future after getting my land I'm going to build my house with multiple 40 ft containers.
Glad we could help
@@TheContainerGuyTV my house plan is to take 3-4 40 ft containers put them side by side and take 3-4 40 ft containers and put them side by side also but at the same time run them long ways like 2 on one side and 2 on the other side with a porch going all the way around and a roof on top
Hi Tom how are you progressing with the land purchase? (Did you need outline planning permission first?)
@@philtucker1224 well as of right now the land purchase is on hold because of job issues as far as the outline permission I live in the rule area of my county so that is not a big problem
@@thomasvincent9027 hi Thomas I hope you eventually get to realise your dream and good luck with your job buddy.🙏
We really want a 4 x 40 seacan home, open concept, with pitched roof for high snow loads. Hoping to start the build early 2025.
How much would a 50 foot, double wide container cost? I went to your website and couldn’t find a price guide.
I live in New Brunswick so wasn’t sure if you had an outlet close by or if I would have to go all the way to Saskatoon?
Seems like it would be much more cost effective, and structurally sound, to build such a structure using conventional construction methods.
Pretty Cool !!
Just wondering what's the flip side of leaving the top uncovered except for solar panels? Thinking of joining two containers side by side to be used as a farm house in Portugal so snow is not an issue. Love the channel BTW.
I have been entertaining the thought of burying two containers: one stacked upon the other (like they ship on train cars). Place a 20' on top of a 40' and a stairwell into the 40 footer. I'd spray the interior and polymer spray and foam insulation sheet cover the exterior.
Very good idea
Great information thank you I subscribed for more
Thank you
Hi
I am interested in the clips for the roof of a shipping container, I am using 4x2 and two high cube and a normal cut in half as per the video where can I but the roof clamps and side clamps from theae are 20ft container.
Nice!👍
I want to see more of these brackets for roof connection to sea container.
3:32 this?
I'm trying to utilize three 40' REEFER containers, currently housing the equipment for my custom shop. They are obviously insulated
and setup in a U shape measuring 40'w x 48l. Do you offer a bracket system to roof the 40' width, wood or metal with a 4:12 pitch. The façade or open end will be finished with traditional construction. This design utilizes the containers for siding and I expect 26 x 36-40 new interior space.
Great inspiration!!
I think the base brackets turned 90 degrees would work.
Maybe prebuilt scissor trusses would be an option. A bit more roof pitch, but could be sized to span multiple bearing points.
Very interested in having an off grid getaway would like more info about cost, delivery and build time when you get things all locked down
Great video. This is for the algorithm
Seems like you are building a house shell around your containers
If you are going to build a building around your containers exactly what purpose do the containers serve?
Structure. Foundation.
Nice job. When are you going to develop a kit to cover the space in between my 20 or 40' containers so I can park my car or tractor in between them? Thanks.
Still waiting!
Hello I just joined the channel an am loving the videos … few questions I thought I just watched a video that said keep it to 1 container ? Lol I’m glad you have found a way to put a few together. Do you deliver to the US ? And I did kind of have my heart set on stacking 2 side by sides but with the truss system will it support a second floor ? Thank you
Hi Michael. This bracket system will support trusses across two containers that are double stacked and spread apart from each other. To go back to sticking with a single container, I still suggest that in each of the 4 containers you plan to use. ie// don't heavily modify the containers. Put your doors, windows and glass in the end wall. Especially the top two containers as they bridge the load to the 4 corner posts and down to the foundation.
I'm looking at putting 2 - 40ft high cube containers together. I'm planning on offsetting it 10ft. I understand the headers and bracing that you are recommending. My question is can you put the containers on pillions or do you have to use a full slabs?
Metal screw piles work great. I'm not a fan of concrete piles for shipping containers. Best to stick with metal. Can run an I-beam across them as a footing.
Do u have a cost brake down. I just have a feeling if you do all that framing around the containers you could prob just have a stick built building concidering the cost of the containers aswell and the labor and abrasives for cutting.
Very industrious! I think if you saved the cost of several sea cans and put that money into a concrete floor you'd be further ahead ! Cheers
I'm not understanding...
If you're going to use wood studs all around the perimeter, what are the containers for? It would be cheaper and easier to just build a stick framed structure at that point. Maybe I'm missing something 🤔
I never understood it either. Storage containers are for storage. Once you cut them up its useless. The cost of spray foam along would pay for framing and batt insulation.
@guyod1 I'm not fond of fiberglass batts, but you're right about the cost. Blown in blanket fiberglass or dense pack cellulose in a double framed wall is highly effective and long-term economical .... and would be cheaper than repurposed containers after all is considered. But what do I know 🤷♂️?

Your interior, at 2:27, is that un-slotted uni strut that you've used to fir out your walls? Will you spray foam the channels? Do you plan to sheet the interior and if so, how do you plan to deal with the bolt heads/strut brackets that stick out over 3/8"? And BTW bro...you are very crafty and you do nice work! Soon I'll be framing my interiors with 1/5/8" steel studs/track. I still have not figured out what I am going to do on my exterior.
ua-cam.com/video/GZ2QSzWlnqQ/v-deo.html
We have a bunch of videos on the strut-lined interiors. Made our own strut-strapping that allows you to secure interior wall covering to either side.
Or…set two 8'WX9'-6"HX53'W wide containers set 24' clear span apart, add arched opening(s), maybe add roll up doors for secure tool storage by bay, on these two containers' interior facing long walls, and set three 8 foot wide sea container style metal framed laminated wood floors or trex plastic composite decking, or Tanzite brand stone decking between the two high cube shipping containers. Then use VersaTube Building Systems 3"-12" pitch metal bolt together 2"X4" web truss system to span the five 8' foot wide sea container's wide three open floors. Ship the three flat 8' wide floors inside, with four 24' spanning channels that bolt to the two outer shipping containers interior walls. So ship all floor parts in the two 9'-6" high cube sea containers. Also ship the pre bundled VersaTube 2"X4" metal truss parts pack in one of the shipping containers. Ship pre-cut heavy gauge commercial metal studs. Also shipped in a container matching pre cut metal outer wall corrugated metal panel sheeting sold in the marketplace as commercial floor B-Decking. Now a nearly pre-cut to size 21' High X 40' Wide X 53' Long building arrives in just two 8'WX9'-6"HX53'W long shipping containers to be set quickly together, roof trussed assembled quickly, assemble end exterior metal stud walls with preferred door window openings. All screws bolted together in three days. Even add roof installation, or skin the bottom of the metal trusses inside the building with lightweight exterior corrugated metal roof sheathing, and add foam insulation board to the lower truss cord. The possibilities to customize are endless to meet the owner's and/or H.O.A. requirements. Move in.
FYI - the wooden floors in the containers are soaked with insecticide to kill any bugs that may invade the container. This done so that bugs are not traveling to other countries. Care should be taken when working with the wood floor .
I have a question. I have a friend that lucked up more than several of these containers.. she wants to join three taking out the inner walls on the two outside and both side walls of the middle container for one bigger room.even though she is paying a fraction of the cost . I still think she will still up spending more.. or is it possible to do what she wants.
Let's just go for the whole enchilada here: Pre-assemble the roof panels with solar panels and ship the panels out with the container sections.
Got a question why don't we just screw the timber on to the container side panel?
Or design a new type of insulation panel can be directly installed outside the container?
This will save the cost.
ty for the video, only thing i dont agree with, "it sheds snow"
Thank you for your video. I'm not so sure about spray foam because it's very difficult to get the formulations right without off gassing issues. I've built a couple of units with shipping containers i've even had them engineered and approved for my county. I'm about to do some again now in Florida. My thought and I'm not sure about this is to use the foam panels normal ones you would get at Home Depot or something. Chemically more stable from what I can figure out. Is anybody comment on this i'm trying to learn
