Do you know what's required to remove the entire floor from a shipping container? Did you know of the many myths going around that the floor is toxic and not safe to remove. In this video Channing is going to demonstrate a new way of removing the floor out of a container a way that doesn't require heavy equipment.
Stay tuned for the end where Channing goes into detail of the misinformation on the toxic chemicals in the floor boards. If you enjoy this video please do us a favor and give it a like. If you'd like to see more, please subscribe to our channel and ring that bell for notifications.
How to Remove the Wooden Floor from a Shipping Container
This guide walks through the proper method for removing the wooden flooring from a shipping container. It covers the tools required, structural considerations, practical techniques, and addresses common misconceptions about container floors.
Whether you are modifying a container for a home build or replacing damaged flooring, understanding the process is essential.
Why Remove a Container Floor?
There are several reasons someone might remove a container floor:
-
Converting a container into a home or office
-
Replacing damaged or contaminated flooring
-
Adding insulation beneath the floor
-
Reconfiguring the container structure
Removing the floor properly ensures the container maintains structural integrity.
Tools and Equipment
Professional operators may use heavy equipment such as a top lift to pop up entire floor sections after screws are removed. However, most home builders will not have access to that machinery.
For DIY removal, the following tools are recommended:
-
Phillips screwdriver or drill bit
-
Skill saw
-
Oscillating multi tool
-
Utility knife
-
Pry bar
-
Ratchet straps
-
Bolt on D rings
-
Container jackers and bottle jack
Bolt on D rings can be attached directly to the floor and used with ratchet straps to lift floor panels. Container jackers attach to corner castings and allow hydraulic lifting with a bottle jack.
Step by Step Floor Removal Process
1. Remove All Screws
Modern containers typically use hardened self drilling Phillips head screws similar to trailer deck screws. Every screw must be removed before attempting to lift the flooring.
Skipping screws will make removal significantly harder.
2. Cut Only Where Necessary
If sections need to be removed selectively, use a skill saw to cut the plywood to about one inch depth. Follow up with an oscillating tool for cleaner edges.
Avoid cutting large panels unnecessarily. Once removed, panels rarely fit back perfectly due to sealants and compression.
3. Cut Through Sealant
Container floors are sealed along the edges with caulking or bitumen sealant. Use a utility knife to cut around the perimeter to free the boards.
This step prevents splintering and makes lifting easier.
4. Pry Carefully
Use a pry bar to gently lift boards. If you plan to reuse them, work slowly to avoid cracking or splitting.
Take care not to damage the steel cross members beneath the floor.
Understanding Container Floor Construction
Shipping container floors are typically constructed as follows:
-
Approximately 1 1/8 inch thick wood planks
-
Often 19 ply teak plywood in shipping line specification containers
-
Budget containers may use bamboo composite or engineered board sealed with bitumen
-
C channel steel cross members approximately 4 3/4 inches tall
-
Cross members spaced roughly 11 inches on center
Sealants and coatings around the perimeter help prevent moisture and pest intrusion.
Avoid cutting or drilling into the steel cross members. They are structural components and weakening them compromises container strength.
Lifting Panels Without Heavy Equipment
An experimental method involved attaching bolt on D rings using 5/16 inch sheet metal screws and lifting panels with ratchet straps.
Even using one inch ratchet straps, the floor panel lifted successfully. This demonstrates that heavy machinery is not always required.
For improved safety and performance, two inch ratchet straps are recommended.
Always prioritize safe lifting practices.
Addressing the Floor Toxicity Myth
There is a widespread claim online that shipping container floors are toxic and unsafe for human use.
Independent laboratory testing commissioned by the National Portable Storage Association has shown that container floors are safe for normal occupancy. The flooring materials are not hazardous under typical use conditions.
The only concern would involve ingesting the material, which is not a realistic scenario in standard building applications.
It is important to rely on verified data rather than internet rumors.
Additional Practical Advice
-
Used containers may be more difficult to work with due to age and hardened sealants
-
Modern containers often use improved anti corrosion components
-
Spray foam insulation can be applied beneath the floor if desired
-
Running plumbing through the cross member cavity is not recommended
Preparation and patience make the process much easier.
Final Thoughts
Removing a shipping container floor is straightforward when done correctly.
The key steps are removing all screws, cutting only where necessary, separating sealants, and protecting the structural cross members.
With the right tools, even DIY builders can remove flooring safely without heavy equipment.
Understanding the structure and avoiding unnecessary damage ensures the container remains strong and ready for its next stage of modification.
