DIY Shipping Container Organization - MODULAR INTERIOR SHELVING SYSTEM

Do you own a shipping container that is completely disorganized from front to back? Are you looking for a way to organize your storage container more efficiently?

Follow along in this video as we install our Modular Interior System with strut channel and CSM Brackets and show you how you can modify your sea can’s interior wall for shelving.

With this framing setup, you can install anything to the struts, such as shelving brackets, pipe racks, tire rack kits, or really anything to design your own organization system inside your shipping container. You can install these struts every corrugation, 2nd, 3rd, or 4th corrugation, or as many as you need for your container. These can also be installed in both the insulated and non-insulated position.

What comes with the CSM Brackets:

2 x Base Bracket
2 x Angle Bracket
4 x 1/4" Thread Cutting Bolt
2 x 5/16" Flange Head Sheet Metal Screw

Tools Required: Strut Channels
Marker
Drill
7/32” Drill Bit
⅜” Hex Head Impact Bit
½” Socket Spring Nuts
Nyloc Nuts (only if you’re not installing roof struts)
⅜” Bolts and Washers

Building a Modular Shipping Container Interior with CSM Brackets and Strut Channel

In this walkthrough, Channing McCorriston, The Container Guy, demonstrates how to install a modular interior system using CSM brackets and strut channel inside a shipping container.

This method focuses on flexibility, minimal container damage, and long-term adaptability. The result is a clean, organized storage system that can be configured for shelving, pipe storage, tire racks, and more without welding or penetrating the container walls.

Why Use a Strut-Based Interior System?

Traditional container interior builds often involve welding or drilling multiple holes through the container walls. That can damage paint, compromise structural integrity, and increase the risk of leaks.

The CSM bracket and strut channel system eliminates those issues.

Key advantages include:

  • No welding required

  • No bolting through container walls

  • Preservation of factory paint and coating

  • Fully modular and adjustable layout

  • Installation achievable with basic tools

The only penetration typically required through the container is for power entry. Everything else mounts directly to the corrugations using self-threading screws.

Bracket Spacing and Layout Options

Shipping container corrugations are spaced approximately 11 inches center to center.

Brackets can be installed:

  • On every corrugation

  • Every second corrugation

  • Every third or fourth corrugation

Spacing depends on your load requirements and budget. Closer spacing increases strength, while wider spacing reduces material cost and installation time.

Strut channels can be mounted flush to the corrugation for non-insulated builds or offset to allow space for spray foam insulation and thermal breaks.

Installation Process Overview

The installation begins by marking the corrugations and pre-drilling holes using a 7/32 inch drill bit.

Bottom brackets are secured to the floor using 3/8 hex head sheet metal screws, which do not require pre-drilling. Top brackets are center-punched, drilled, and fastened with self-tapping screws to ensure proper alignment.

Once brackets are mounted, the strut channel slides into place.

The system uses spring nuts inside the strut channel. These specialized nuts include a spring backing that holds them in position while bolts are tightened. They insert one way and resist spinning, making installation efficient and adjustable.

Modular Storage Accessories

One of the biggest advantages of this system is its flexibility.

Heavy Duty Shelving Brackets

The 18-inch shelving brackets allow adjustable height placement and can support two 2x10 boards, creating a shelf roughly 19 to 20 inches deep.

When shelving is installed on both sides of the container, a center aisle greater than three feet remains, preserving usable walking space.

Bolt holes spaced every four inches allow precise height adjustments.

Pipe Racks

Pipe racks mount using the same spring nut system and are ideal for storing pipe, ladders, chains, extension cords, and straps.

Because of angled mounting profiles, some bolts require tightening with a wrench. Rubber caps can be added to exposed edges to reduce injury risk.

Tire Rack System

The tire rack setup uses galvanized angle brackets, strut channel, and 1¼ inch EMT conduit to create a triangulated frame.

Crossbars are secured with strut clamps, and spacing can be adjusted to fit different tire sizes. This system can also be adapted for other bulky storage needs.

Technical Details

  • Corrugation spacing: approximately 11 inches

  • Drill bit size: 7/32 inch

  • Screws: 3/8 hex head sheet metal screws and self-threading screws

  • Shelf bracket width: 18 inches

  • Tire rack tubing: 1¼ inch EMT conduit

Why This System Works

The CSM bracket and strut channel approach delivers:

  • Strong mounting without structural compromise

  • Modular flexibility

  • Reusable and adjustable connection points

  • Expandability for future upgrades

  • Clean, professional interior layout

Spring nuts create solid anchor points that can be repositioned as storage needs evolve.

Final Thoughts

Transforming a shipping container into a modular storage system does not require welding or permanent structural alterations.

With CSM brackets, strut channels, and adaptable accessories, you can build a flexible interior that grows with your needs while maintaining the integrity of the container.

This system offers a practical, durable, and professional solution for maximizing container storage space.
