Join 'The Container Guy' team as they unveil their latest shipping container modification - with a custom two-toned paint job that's hard to miss!

This innovative mine site shack looks sweet on the outside, and even sweeter on the inside... Follow along as we spray foam, insulate strut line, strut strap, install our Reline wall panels and custom paint.

We'll install heavy duty shelving down both sides, with a work desk, a nice little chair for a guy to work at, and some really nice Russo tool cabinets. We also put an anti-slip rubberized flooring down the walkway, electrified the container with lights down the center, put plugs throughout and installed a 120/240 volt panel with exterior junction box.

40-Foot High Cube Mine Site Shack Conversion

Channing McCorriston, The Container Guy, showcases the complete transformation of a 40-foot High Cube one-time-use shipping container into a fully outfitted mine site shack. This build highlights advanced insulation methods, modular interior systems, heavy-duty shelving, and a robust electrical setup designed specifically for demanding industrial environments.

The project demonstrates how a standard shipping container can be engineered into a durable, high-performance workspace tailored for field operations.

Spray Foam Insulation and Strut Lining System

The container is fully spray foam insulated to create a tight, efficient thermal envelope. Instead of traditional steel stud framing, the interior is lined entirely with strut channel and strut strapping.

This system offers several advantages:

• Strong structural mounting points

• Clean routing for electrical conduit

• Long-term durability

• Full modular flexibility

Special corner casting covers are installed before spray foam application to maintain a continuous vapor barrier. These covers eliminate cold spots around structural corners and preserve interior ceiling height.

The result is a fully encapsulated, insulated shell designed to perform in harsh industrial conditions.

Heavy-Duty Shelving and Interior Workstation

The mine site shack is built for function and load capacity.

Custom shelf brackets rated at 350 pounds each are mounted along both sides of the container. With four brackets per shelf assembly, each unit supports up to 1,400 pounds.

Additional interior features include:

• A Uline workbench with integrated power access

• Russo tool cabinets securely bolted into the strut framework

• Anti-slip rubberized flooring for improved safety

The layout supports both storage and workspace needs, making it ideal for industrial and maintenance operations.

Electrical System Integration

The container is fully electrified with a practical and expandable setup.

Key features include:

• Four 4-foot LED strip lights along the centerline

• Multiple interior outlets

• Two ceiling-mounted 5,000-watt heaters

• A residential-style electrical panel

• An exterior junction box for simplified site power connection

The exterior junction box allows electricians to safely connect power without opening the main panel, improving compliance and job site safety.

Electrical conduit is mounted cleanly using the strut channel system and P straps, allowing additional circuits or upgrades in the future.

Exterior Finishing and Details

Despite the additional labor involved, the container received a custom two-tone paint job, elevating its appearance beyond a typical industrial unit.

Important finishing details include:

• Careful masking of the CSC plate to preserve load information

• Installation of a container door flashing kit

• Proper spray foam insulation around doors without interfering with rubber seals

• Exterior lighting and power outlets near the man door

• Customer-supplied decals for branding

The final product balances rugged durability with professional presentation.

Modular Design and Future Flexibility

One of the strongest features of this build is its modularity.

The full strut channel interior allows shelving, pipe racks, cabinets, and equipment to be rearranged or expanded as operational needs change. Nothing is permanently locked in place.

Future improvements may include combining strut channels with alternating steel studs in office-style builds to reduce labor costs while maintaining durability.
