What Is a Steel Container Cover?

A steel container cover — also called a sea can cover, conex cover, ISO container cover, shipping container roof kit, or container canopy — is a pre-engineered steel roof structure that spans between two shipping containers.

The containers act as your walls and foundation. The steel roof creates a fully covered, clear-span space underneath with zero interior supports. The result is 100% usable space — no columns, no beams, nothing in the way.

Container covers are used across Canada for equipment storage, vehicle shelter, covered workspaces, agricultural applications, oil and gas operations, mining, construction staging, logistics, and industrial use.

How Does a Container Cover Work?

The concept is simple. You position two shipping containers parallel to each other at the spacing that matches your cover width. The steel roof kit mounts directly to the top of the containers using engineered mounting plates and hardware.

Once assembled, you have a covered, weather-protected space between your containers — protected from snow, rain, wind, and UV damage — engineered to last decades.

End walls, man doors, overhead doors, skylights, vents, and insulation can all be added to customize your cover for your specific application.

What Sizes Are Available?

CNC container covers are available from 20 feet wide up to 60 feet wide and beyond, in any length. Common widths include 20, 25, 30, 35, 40, 45, 50, 55, and 60 feet.

Length is flexible — match it to your containers (20ft or 40ft) or extend it as long as your project requires.

Arch Style or Straight Wall?

Two main styles are available:

Arch style — a curved, rounded roof profile. Naturally sheds snow and rain. Fast to assemble. Most popular for farms, job sites, oil and gas, and agricultural applications across Canada.

Straight wall — vertical walls with a peaked roof, similar to a traditional building shape. Maximizes interior space at the edges. More traditional appearance. Popular for commercial, industrial, and logistics applications.

Both styles are available in all widths and lengths. Both are engineered for Canadian snow and wind loads.

What Does a Container Cover Cost in Canada?

Every container cover is custom-engineered for your specific project and location, so there’s no single published price. Cost depends on width, length, style, accessories, and your location in Canada.

What we can tell you is that a container cover is significantly less expensive than a traditional steel building of comparable size — often by tens of thousands of dollars — because you’re not paying for a foundation, wall panels, or a construction crew.

Do You Need a Permit?

Permit requirements vary by province and municipality. Container covers are generally considered non-permanent structures in most Canadian jurisdictions, which means they typically require fewer permits than traditional buildings.

In agricultural zones across Canada, container covers often require no permit at all. In urban and commercial zones, a simplified permit process is typical.

Every CNC container cover comes with stamped engineering drawings, which is what municipalities need if a permit application is required.

Always check with your local municipal building department before installation.

How Long Does Installation Take?

Most standard container cover kits can be installed by a crew of 2-4 people in one to two days using basic tools. No specialized contractors required for most installations.

Larger or more complex spans may benefit from a telehandler or boom lift to speed up panel installation.

What Accessories Are Available?

End walls — close in the ends for full weather protection and security

Man doors — pedestrian access without opening the full end

Overhead doors — vehicle and equipment access with closure

Skylights — natural light inside the covered space

Ventilation — airflow for livestock, equipment, or work areas

Insulation — temperature control for sensitive equipment or year-round work

Gutters and downspouts — water management
