We Modified a 10' Shipping Container Into a Bottle Storage Shack

Follow along as we modify this 10’ shipping container into a Bottle Storage Shack. In this container modification, we will be replacing the wood floor with bar grating, installing strut channels along the wall, putting a partition wall down the middle, installing Big Air 45 vents, and then inserting slotted struts horizontally to hold the bottles in place against the wall.

Hope you learn something!

Converting a 10-Foot High Cube Shipping Container into a Gas Bottle Storage Shack

In this walkthrough, Channing McCorriston, The Container Guy, demonstrates how a 10-foot high cube shipping container can be modified into a secure and ventilated gas bottle storage shack.

This build focuses on safety, ventilation, structural reinforcement, and modular mounting systems to ensure compressed gas cylinders are stored properly and securely.

Removing the Wood Floor

The first major step was removing the original wood floor.

Because the container is intended for gas storage, eliminating flammable materials is critical. Once the wood panels were removed, the exposed steel surfaces were treated with a rubberized spray coating to protect against corrosion.

Steel stiffeners were welded underneath to provide solid support for a longitudinal partition wall that divides the container into sections.

Installing Steel Bar Grating

Instead of reinstalling a solid floor, steel bar grating was installed.

This serves two important purposes:

  • Eliminates combustible flooring

  • Acts as a lower ventilation system

The open grating allows heavier-than-air gases to dissipate downward and escape safely. The grating was aligned squarely and secured with longer self-tapping screws to ensure strength and stability.

The result is a floor system that improves both safety and airflow.

Dual Ventilation Design

Proper ventilation is essential when storing gas cylinders.

This container uses a dual ventilation system:

  • Lower ventilation through the steel bar grating

  • Upper ventilation via large vents installed on both sides

This design allows gases to exit regardless of density. Lighter-than-air gases rise and escape through upper vents, while heavier gases move downward and out through the grated floor.

The combination creates a passive ventilation system that reduces the risk of hazardous gas buildup.

Installing the Partition and Strut System

A partition wall was installed down the center of the container to create organized storage bays.

Strut channels were welded and secured to serve as mounting points for modular interior systems. Slotted strut was installed along the walls and partition, allowing adjustable anchor points for securing gas bottles.

Spring nuts and heavy-duty self-tapping screws were used to create strong, adjustable connections.

Gas cylinders can be secured using:

  • Chains

  • Ratchet straps

  • Bungee cords

The slotted design allows bottle height and spacing to be adjusted as needed.

Exploring Square Tube Mount Brackets

This build also tested square tube mount brackets as a potential alternative to traditional bracket systems.

These brackets are galvanized, gusseted, and simpler to manufacture. The goal is to reduce cost and minimize exterior penetrations while maintaining strength.

They provide strong internal anchoring and represent a practical option for modular container interiors.

Technical Highlights

  • Container type: 10-foot high cube

  • Floor material: Steel bar grating replacing wood

  • Sidewall thickness: Approximately 1.6 mm

  • End wall thickness: Approximately 2 mm

  • Fasteners: 3/8 inch hex head and quarter-inch self-tapping screws

  • Interior system: Slotted strut with spring nuts

  • Corrosion protection: Rubberized coating on exposed steel

Why This Build Works

This modification prioritizes safety and adaptability.

Key advantages include:

  • Removal of flammable materials

  • Passive dual-direction ventilation

  • Reinforced support for interior partitions

  • Fully adjustable modular strut system

  • Protective coatings for long-term durability

The integration of ventilation and structural upgrades ensures the container performs reliably in an industrial environment.

Final Thoughts

Transforming a 10-foot high cube container into a gas bottle storage shack requires more than simply adding racks.

By removing combustible flooring, reinforcing structural elements, installing proper ventilation, and building a modular interior system, the container becomes a purpose-built solution designed around safety and flexibility.

The result is a durable, adaptable storage unit ready for industrial gas cylinder use.
