What a Flatbed Load of Totes Teaches You About Securement
Two rows of ten, stringers fore and aft, strapped over the cage rail. Everything else is a way to fold a cage.
The short version
Strap over the steel cage top rail, never across the bare bottle. Never stack full containers in transit. Never stack unlike pallet types. Those three rules prevent nearly every load failure we see.
Containers are forgiving cargo right up until they aren't. Get the pattern and the securement right and a load of forty travels from Austin to Odessa without anyone thinking about it. Get one of three things wrong and you arrive with folded cages and a shifted load.
The pattern
- 1Two rows of ten, with the pallet's 40-inch dimension across the trailer. That gives two rows across an 8.5-foot deck with a few inches to spare.
- 2Heaviest units to the front. Standard weight distribution — keep the load off the trailer tail.
- 3Valves turned inboard, toward the centre of the deck, so nothing catches on a strap, a post or a passing wall.
- 4Two straps per row, over the top rail of the steel cage, tensioned firm rather than crushing.
- 5Corner protectors on the cage edges. Cheap, and they stop a strap cutting into galvanizing on a long run.
The three failures
1. Stacking full containers
The single most expensive mistake. A cage top rail is rated for static stacking on level ground — not for 2,400 lb bouncing over a farm-to-market road. Braking, potholes and lane changes all put dynamic loads through a frame that was never designed for them.
The result is folded cages, a shifted load and sometimes a bottle failure. Empties stack two high without issue. Full containers stack one high, always.
2. Strapping across the bottle
HDPE creeps under sustained load. A strap tensioned across the bare bottle deforms it over the course of a long haul and can craze the shoulder. The cage exists precisely so there's something structural to strap to — use it.
3. Mixed pallet types stacked
A steel-base container stacked on a composite-base container concentrates load exactly where the lower deck is weakest. The load paths don't line up. Stack like on like, or don't stack.
Freight class, if you're booking your own carrier
We ship truckload and consolidated, so classification rarely appears on our quotes. It matters a great deal if you book LTL yourself, because empty containers are low density and high cube — which puts them in the higher NMFC bands.
| Configuration | Weight | Cube | Density (lb/cu ft) |
|---|---|---|---|
| Single 275 gal, empty | 130 lb | 51 cu ft | ≈ 2.5 |
| Single 330 gal, empty | 160 lb | 59 cu ft | ≈ 2.7 |
| Two 275s stacked, empty | 260 lb | 102 cu ft | ≈ 2.5 |
| Cut second-life build, nested | 110 lb | 34 cu ft | ≈ 3.2 |
Treat that as budgeting orientation only. NMFC classification depends on the carrier's own item interpretation, packaging and stowability assessment — confirm the actual class with them, and expect a reclass if you guess low.
Tarping
Not for weather protection. HDPE and galvanized steel don't care about rain. We tarp food-grade and rebottled stock to keep road grime off units that will be filled soon, and to protect the wash records travelling with them.
Inspect before you sign
Walk the load. Cage corners, bottle condition around the outlet, valve seats, lids. Note anything on the delivery paperwork before the driver leaves — resolving it at the tailgate is dramatically easier than resolving it a week later, and every honest supplier would rather you did.
