WHAT IS A PORTABLE STORAGE CONTAINER?

A portable storage container is designed for transportation, on-site storage, and on-demand delivery. The most common applications include residential storage projects, retail inventory overflow and holiday staging, moving and relocation, restoration and remediation work, and active construction job sites. Portable storage companies typically store the containers at a warehouse or yard and deploy as requested via truck and trailer.

HEAVY-DUTY STEEL CONSTRUCTION

Every Boxwell portable storage container is built with heavy-duty steel construction engineered for long-term durability, transportation, and repeated jobsite use. Reinforced corner posts, cross-members, and structural framing help maintain container strength and stability during delivery, lifting, stacking, and placement.

HIGHEST GRADE, BEST QUALITY STEEL

Similar to ocean containers, Boxwells are built with premium Corten steel that resists corrosion and weathering to ensure long-lasting durability. SPA-H and SPA-C grade steel are utilized in the fabrication of Boxwell containers. 

STAINLESS STEEL HARDWARE WILL NOT RUST

The door lock assembly, hinges, T-latches, and hardware are made of stainless steel. 

EASY-TO-ASSEMBLE CONTAINERS

Shipped flat-packed for cheaper freight, assembly of the portable units is fast and easy. Assembly is fast and straightforward with just 24 total nuts and bolts, allowing installation in as little as 30 minutes.

Stackable Storage Containers

10,000 LB LOAD CAPACITY

Every Boxwell portable storage container is engineered to handle up to 10,000 pounds of cargo. 

FORK POCKETS IN BASE FOR EASY MANEUVERING

Built into the base of Boxwell portable containers are a number of transport-ready features. This includes fork pockets for easy moving, loading, and stacking.

STACK THREE-HIGH, FULLY LOADED

Even while fully loaded, Boxwell units stack up to three-high. This is ideal for businesses that store container inventory in warehouses, depots, and outdoor storage yards where maximizing vertical space is critical.

GOLD STANDARD PORTABLE STORAGE ROOF DESIGN

Corrugated roof designs have been proven across the global shipping industry for decades due to their superior strength, drainage, and long-term durability. Boxwell applies the same proven engineering principles used in marine shipping container roofs to our portable storage containers, delivering a stronger, more reliable roof system built for transportation, outdoor exposure, and daily commercial use.

CORRUGATED ROOFS VS. FLAT ROOFS FOR PORTABLE STORAGE CONTAINERS

Similar to marine shipping containers, Boxwell portable storage containers feature corrugated steel roofs engineered for long-term strength and durability. The corrugated roof design increases structural rigidity during transport, resists sagging over time, and mitigates pooling water.

Unlike flat roof designs that flex, pool water (leading to corrosion and rust), and weaken over time, corrugated roofs have been proven across the global shipping industry for decades in demanding real-world environments.

Despite the added strength of the corrugated design, Boxwell containers remain fully stackable for efficient storage.

Boxwell roof fits "shoebox" style over walls, guiding water away from the container.

OVERHANGING ROOF DESIGN KEEPS WATER OUT

Boxwell portable storage containers feature a shoebox-style roof design that fits over the container walls.

The roof overhang directs water runoff away from the walls, eliminating leaks and water intrusion, and improving long-term weather resistance.

TRANSPORT-READY, FULLY SEALED DOORS

FULLY SEALED AND GASKETED SWING DOORS

Boxwell swing doors are fully sealed and gasketed to protect against water, wind, dust, and pests. Designed for over-the-road transport and long-term outdoor exposure, the door system keep contents protected in demanding real-world conditions.

HEAVY-DUTY SECURITY LATCH SYSTEM

Boxwell’s latch mechanism is engineered for strength, security, and daily ease of use. Welded and riveted components, along with a solid steel locking pin, help protect renters’ belongings during transport and storage.

Each door includes a built-in space for an override lock, plus an interior emergency release pull cord with a glow-in-the-dark safety marker.

DOORS OPEN FULLY WITH 180° HINGES

Boxwell container doors swing fully open to 180 degrees for easier loading, unloading, and access.

T-LATCHES FOR SAFER LOADING

Stainless steel T-latch catches securely hold the doors open during loading operations, helping improve convenience, safety, and jobsite efficiency.

BUILT-IN MOBILITY FEATURES

Boxwell portable storage containers come ready-made with a range of transportation-focused features engineered for safe, efficient delivery and repeated over-the-road use. Designed specifically for portable storage businesses, Boxwell containers deliver long-term durability, reliable performance, and smooth compatibility with a wide range of delivery systems.

The standard features on our portable containers include vertical e-track (interior), tie-downs (interior), forklift pockets, mule pockets, heavy-duty receiver tubes, extra-strength D-ring, and rubber feet.

DESIGNED FOR VENTILATION AND MOISTURE CONTROL

Boxwell portable storage containers are engineered with multiple moisture-control features designed to keep contents dry in a wide range of climates. The result is a storage container built to better protect stored contents during transportation and long-term outdoor use.

An anti-condensation desiccant spray is applied to the ceiling of all Boxwell containers.

Anti-Condensation Spray Applied To Ceiling

A military-grade anti-condensation spray is applied to the ceiling of all Boxwell containers. This lightly textured desiccant material absorbs moisture present in the environment, protecting the stored contents within. 

A Boxwell portable storage container includes wall vents for proper air flow.

Wall Vents Allow Proper Air Flow

All Boxwell containers feature built-in wall vents designed to promote consistent airflow and reduce moisture buildup inside the container. Each container includes ocean container-style vents with integrated bug screens to help keep pests, insects, and debris out while maintaining proper ventilation.

Raised Floors for 360-Degree Breathability

Every Boxwell portable storage container is built on a steel base that elevates the floor off the ground. This raised-floor design allows air to circulate around all sides of the container, promoting 360-degree airflow beneath and around the unit. Improved airflow helps reduce trapped moisture, enhances interior breathability, and supports a drier storage environment in a wide range of climates.
