Quick Answer: A retired cube van box is the cheapest steel-ish shed on Kijiji, and a 20ft shipping container outlasts it on every line that matters: corten walls instead of box-knife aluminum skin, a 28 mm marine plywood floor at ground level, a snow-rated steel roof instead of cracking translucent fiberglass. Van Blanc grades and delivers real bins across Ontario in 1-3 days.

The Auction Buy That Looks Like a Bargain
Every farm auction and equipment liquidation in Ontario ends the same way: a retired cube van box, pulled off its chassis, hammer-priced at less than a weekend of groceries, and somebody’s neighbour hauling it home for “storage”. Kijiji has a whole category for them. The listings say it plainly: no longer roadworthy, makes a great shed.
Sometimes it does, for a while. We sell against these boxes every week from our Brantford yard, and this page is the comparison we walk buyers through on the phone: what a van body is actually made of, what fails first, and where a 20ft shipping container earns the difference. We will also tell you when the cheap box is honestly all you need, because a fair comparison is the only kind worth publishing.
What Is a Cube Van Body Actually Built From?
A dry-freight van body is engineered to be light, because every kilogram of box steals a kilogram of payload. Body manufacturers build them as aluminum or thin galvanneal frames skinned with sheet aluminum or fiberglass-reinforced plywood panels, riveted or screwed at the seams, over a floor of roughly 28-32 mm laminated hardwood or softwood ply on crossmembers sized for highway loads, not decades of ground contact. That is the right recipe for a truck. It is the wrong recipe for a building.
A shipping container is built to the opposite brief. ISO 668 governs a welded 14-gauge corten steel shell engineered to carry over 28,000 kg gross, stacked nine high, through ocean salt spray for decades. Nothing on a van body corresponds to that. The container’s problem was never being tough enough; it was only ever getting the box to your yard, which is what our tilt-deck delivery does.
The Skin Test
Stand at the wall of each box with a utility knife. Sheet aluminum van skin cuts; FRP panel delaminates and cuts; 14-gauge corten laughs at anything short of a grinder with a cutting disc. If the contents matter enough to lock, the wall has to be worth locking.
Why Does Every Old Van Body Leak From the Top?
Look up inside a cube van box and you will usually see daylight glowing through a translucent fiberglass roof panel. Manufacturers fit them so drivers can find freight without a lamp; it is a genuinely clever feature for a delivery truck. Ten Ontario winters later it is the failure point: the panel clouds, embrittles under UV, and cracks under snow it was never rated to hold, and the seam caulking that sealed it on the highway dries out standing still. Trailer and body shops publish long-term storage checklists for exactly this reason, and resealing the roof is a standing line item on all of them.
The container roof is the same 14-gauge corten as the walls, welded, crowned to shed water, and rated for a loaded container stacked on top of it in a ship’s hold. A Haliburton snow load is not a consideration; it is a rounding error. There is nothing to reseal because there is no seam to open. One rag-wipe of the door gaskets a year is the entire maintenance calendar.
What Happens When a Truck Box Sits on the Ground?
Three things, in order. First, the floor: van-body crossmembers expect airflow underneath from highway speed, and parked on soil they trap damp against the hardwood ply until it delaminates from below. Second, the frame: the thin rails rust where they touch grade, and the box slowly racks out of square until the roll-up door jams in its tracks. Third, the mice arrive, because a roll-up door on a wooden floor seals like a screen door, and every van body in a field becomes a rodent hotel by its second winter.
Containers sit on the ground for a living. The four corner castings carry the weight on blocking or a gravel pad, the floor rides above grade on steel crossmembers, and the marine door gaskets that kept Pacific spray off cargo keep mice out of your seed. This difference is not cosmetic. It is the difference between a box designed to be a structure and a box improvising as one.
Van Body vs Sea Can, Line by Line
| Factor | Retired cube van body (typical 16ft) | 20ft shipping container |
|---|---|---|
| Walls | sheet aluminum or FRP over light framing | welded 14-gauge corten steel |
| Roof | translucent fiberglass panel, caulked seams | welded corten, ocean stack-rated |
| Floor | ~28-32 mm hardwood ply on highway crossmembers | 28 mm marine plywood, forklift-rated steel frame |
| Ground contact | never designed for it; rots and racks | engineered for it via corner castings |
| Door | roll-up, worn tracks, loose seal | double cargo doors, marine gaskets, lockbox-ready |
| Security | knife-openable skin, hasp on aluminum | corten shell, shielded puck lock |
| Typical remaining life as a shed | a handful of years before roof and floor go | 25+ years on newer grades, decades even used |

The Honest Apples-to-Apples: Our As-Is Grade
The fair price comparison for a retired van body is not a new container; it is our cheapest one. Van Blanc sells four grades: new (one-trip), Cargo Worthy, Wind and Watertight, and As-Is. An As-Is bin has structural questions we point out honestly, floor damage, a stiff door, real rust, and it still starts life as a welded corten structure that was built to carry thirty tonnes through a hurricane. At auction-adjacent money, the As-Is container and the van body finally compete on price, and the steel wins the next fifteen years. One step up, a Wind and Watertight 20ft costs more than the auction box and removes every one of the failure points on the table above. That gap is what a quote conversation is for: call 519-754-6844 and we will price both grades against whatever the auctioneer is waving at.
Paul LeBlanc, owner: “A Burford farmer told me he had bought three truck boxes over the years because they kept being cheap. The first roof cracked, the second floor went spongy, the third became the chicken coop. He put one Wind and Watertight 20-footer beside the barn five years ago and told me last fall it was the first box he never had to think about.”
When the Van Body Is Still the Right Buy
Buy the cheap box with a clear conscience when the job is genuinely low-stakes: covering firewood, sheltering calves out of the wind, holding fence wire and fuel jugs where a leak or a mouse costs you nothing. At near-scrap prices doing near-scrap jobs, it is honest value, and no container salesman should pretend otherwise. The line crosses the moment the contents matter: tools with resale value, seed and feed that must stay dry, documents, equipment with copper in it. Steel that seals and locks stops being a luxury exactly there.

Frequently Asked Questions
Is a used cube van box cheaper than a shipping container?
At auction, usually yes, and it is priced that way because it is at the end of its life. Our As-Is grade competes closest on price while starting from a welded corten structure. Grade, size, and delivery distance set the real number, so call 519-754-6844 for both figures side by side.
Do cube van boxes leak?
The translucent fiberglass roof panel is the usual culprit: it clouds, embrittles, and cracks under snow load, and the seam caulking dries out once the box stops moving. Body shops list roof resealing as routine storage maintenance. A container roof is welded corten with no panel and no seam to fail.
Can you put a cube van body directly on the ground?
You can, and that is what kills it: the floor traps damp and delaminates, the thin rails rust at grade, and the box racks until the roll-up door jams. Van bodies were engineered for a chassis with airflow underneath. Containers carry their weight on corner castings designed for ground contact.
How long does a van body last as a shed?
Owners typically get a handful of useful years before the roof panel or floor gives, depending on how it started life. A Wind and Watertight container routinely gives decades in the same duty, and a new (one-trip) unit carries a 25-plus year expectancy.
What is the container equivalent of an auction truck box?
Our As-Is grade: the cheapest bin in the yard, sold with its faults pointed out honestly. It is the fair price comparison, and it still brings a welded steel shell the van body never had. We will tell you plainly whether As-Is or Wind and Watertight fits your use.
How fast can Van Blanc deliver compared to hauling an auction box?
1-3 days to most of Ontario from our 4 Brantford yards, placed exactly where you point by a tilt-deck driver who calls before the run. No borrowed float trailer, no crane favours, and you pay when the bin is on your ground.
