Storage Container with Three Roll Up Doors One Open

Custom Storage Containers

Interport’s customized storage containers offer a durable, secure, and flexible solution for virtually any storage need. Built from heavy-duty steel ISO shipping containers, these units provide ground-level access, a weatherproof design, and the ability to customize layouts, access points, and interior features to match your exact requirements.

Whether you’re expanding a self-storage facility, protecting valuable equipment on a job site, adding storage space at a business, or securing personal belongings at home, Interport’s modified containers deliver dependable, long-lasting performance.

Built for Strength, Designed for Versatility

Each custom unit begins with a steel, wind- and watertight shipping container — engineered to withstand harsh environments and secure your stored materials. From there, Interport’s in-house modification team can tailor the container with features such as:

Our containers can be configured as single-bay units, multi-bay roll-up door storage, or large-volume storage options — all delivered ready to use.

Common Applications for Modified Storage Containers

Interport’s customizable storage units support a wide range of industries and personal needs:

Corporate & Commercial Storage

Ideal for businesses needing extra space for equipment, surplus inventory, seasonal merchandise, or document archives. Add shelving, multiple doors, or climate control for improved organization and accessibility.

Self-Storage Facilities

Operators can instantly expand rentable units with steel, ground-level storage bays featuring roll-up doors, multi-unit layouts, and branded paint. Durable, secure, and far more economical than new construction.

Personal & Residential Storage

Use as a backyard shed, garden center, hobby workshop, tool storage, or additional household storage. Containers keep items safe from weather, pests, and theft.

Moving & Relocation Storage

Perfect for temporary storage during a move — or for protecting goods during overseas shipping or long-term transition periods.

Vehicle & Equipment Storage

A secure option for storing tractors, classic cars, motorcycles, ATVs, or race cars. Containers can be modified with ramps, ventilation, and reinforced flooring.

Agricultural & Farm Storage

Containers protect hay, feed, fertilizers, tools, and farm machinery from rain, snow, and sun exposure. Add shelving or roll-up doors for easier access.
