Follow along in this video as we showcase how to cut a shipping container in HALF for 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! 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!
Cutting Shipping Containers in Half to Build a Double Wide with a Pitched Roof
This project documents the ongoing development of a method to cut shipping containers in half and reassemble them into a double wide structure with a pitched roof. The process is complex and still evolving, but it represents a major step forward in modular container construction.
The goal is to create a wider living or working space while achieving a 3 over 12 roof pitch, improving snow shedding and residential compatibility.
The Double Wide Concept
The method involves cutting a standard height container in half and attaching each half to the sides of a high cube container. This configuration allows vertical structural posts to sit four feet off the wall instead of in the center, creating more usable interior space.
The pitched roof design improves drainage, meets common building standards, and gives the structure a more traditional appearance.
Exterior Studding Bracket System
A new exterior studding bracket system supports this process. The brackets allow exterior framing to be added to the container walls, increasing flexibility for roofing and finishing.
This system plays a key role in supporting the structural changes required for the double wide configuration.
The Cutting Process
The cutting process is methodical and must be done safely.
First, the cross members underneath the container are cut while the container sits on modification beams outside the shop. This provides safer access.
Inside the shop, a wood cutting skill saw is used to cut the plywood floor to approximately one inch depth. A metal cutting saw then cuts through the cross members.
The floors of the two halves separate first. After that, additional cuts are made to the headers, footers, roof sheeting, and side walls.
Structural Challenges
Once cutting begins, structural issues appear.
The roof corrugations tend to sag inward as the structure separates. This sagging causes headers to bow and complicates alignment. The halves must be manually squared before reassembly.
To stabilize the structure after separation, vertical posts are installed quickly. This maintains alignment and simplifies further measurements.
Alignment and Assembly Solutions
Several features have been developed to improve assembly accuracy.
A pin and dowel system in the footers allows the floor sections to auto align when brought together.
A drip cap is installed on the header to shed water and prevent pooling at the joint.
Bolt style bridge fittings are used to pull the two halves together. In some cases, a crane lifts the connected header pieces to straighten them and create a cleaner joint.
These techniques improve precision but require careful execution.
Welding Complications
Welding plays a major role in the current process, but it introduces challenges.
Heat from welding causes steel to warp, leading to misalignment. This makes final fitting more difficult and time consuming.
To reduce these issues, the team is exploring alternatives such as folded sheet metal systems that could simplify connections and minimize heat distortion.
Reducing welding is a key goal for improving efficiency.
Iso Corner Castings
Iso corner castings are required when containers are used underground because they provide secure lifting points.
However, adding them increases complexity. Cutting, welding, and preheating are necessary during installation.
For above ground container homes, iso corner castings are not required, which simplifies the build.
Experience and Refinement
The team has cut containers in half six times and continues to refine the process. Each iteration reveals new lessons.
At this stage, the method is not suitable for do-it-yourself builders. The process requires heavy equipment, structural understanding, and careful planning.
The long-term vision is to have containers manufactured in a way that allows them to be split upon arrival. Pre-designed split containers could dramatically reduce local labor and cost.
This concept could take about a year to develop into a market-ready solution.
Final Thoughts
Cutting and joining shipping containers to create a double wide with a pitched roof is technically possible, but it is complex.
Structural sagging, header bowing, welding distortion, and alignment challenges all require thoughtful solutions.
Innovations such as pin and dowel alignment systems, drip caps, and improved bracket designs show promise.
With continued refinement and possible pre manufactured solutions, this approach could become a practical way to build wider, pitched roof container homes in the future.
