Shipping Container Modifications

At Supreme Shipping Containers, we know that a standard steel box is just the beginning. Our mission is to transform these rugged structures into functional assets through professional shipping container modifications that solve real-world problems. Whether you are outfitting a remote site in the oil patch, expanding a farm near Lethbridge, or building a backyard workshop, we provide the engineering and craftsmanship to make it happen.

Every modification is handled by our own in-house team in Edmonton, Alberta. We don’t cut corners; we use industrial-grade materials specifically selected to withstand the coldest temperatures and the hottest summers on the Canadian Prairies.

Painting & Protective Coatings

Appearance matters, but protection is paramount. Every modified unit at Supreme Shipping Containers undergoes a rigorous prep process. We grind away surface rust and apply a high-build, marine-grade coating designed to resist fading and corrosion.

High-Access Roll-Up Doors

Standard container doors are heavy and require significant clearance. Our roll-up doors offer one-handed operations and are ideal for frequent access.

Sizes: Choose from 7ft, 8ft, 10ft widths.
Durability: Features weather-stripping to keep out snow and dust, and integrated locking mechanisms for security.

Windows & Security Bars

Bring natural light into your workshop or office. We install 3' x 3' and 3' x 4' double-pane windows that are fully sealed against the Alberta wind.

Security First: For added peace of mind, we can install custom-welded security bars or shutters to protect the glass when the site is unattended.

The "Supreme" Security Lockbox

Don't settle for bolt-on accessories. We weld heavy-duty, oversized steel lockboxes directly to the door frame. These are designed to fully shroud your padlock, making it impossible for bolt cutters or prying tools to reach the shackle.

Partitions

Partition walls are ideal for dividing your shipping container into separate compartments. This is perfect for setting up public storage or creating unique areas within a single container.

Available as a complete wall or a welded frame for you to add wood and drywall to.

Insulation & VentILATION

In Alberta, condensation (or "sweating") is a major concern. We offer several levels of protection to keep your cargo dry and your team comfortable.

Insulation: Choose between rigid board insulation or high-R-value spray foam for year-round temperature control.
Ventilation: From simple louvered vents to solar-powered turbine vents and framed HVAC openings, we ensure your container "breathes" properly.
