Conical steel drum
Tapered body; empties nest
Straight-sided steel drum
Cylindrical body; empties do not nest
Side by side
| Conical steel drum | Straight-sided steel drum | |
|---|---|---|
| Typical use | Bulk food, pastes, chemicals, especially where empties return | General industrial liquids, powders and solids |
| Relative capacity | Slightly less internal volume for a similar footprint | Full cylindrical volume for the footprint |
| Empty volume | Nested empties occupy a fraction of the full height | Empty occupies the same space as full |
| Reusable potential | Designed with return loops in mind | Reusable, but the empty leg costs more |
| Transportation | Far more empties per trailer | Empty returns move mostly air |
| Storage | Empties stack into a small footprint | Empties consume warehouse or yard space |
| Material | Steel, coated or lined to suit the product | Steel, coated or lined to suit the product |
| Sanitation | Open-head versions clean easily; liners remove most of the burden | Same, depending on head style |
| Handling | Care needed separating nested empties | Familiar handling everywhere |
| Advantages | Attacks the cost of the empty leg directly | Ubiquitous, simple, no handling learning curve |
| Limitations | Only pays back where empties travel or are stored in quantity | No answer to the empty-volume problem |
Conical steel drum — When this makes sense
- Empties come back, or empty storage is a real constraint
- You want reuse to work without the return freight eating the benefit
- Yard and warehouse space is tight
Straight-sided steel drum — When this makes sense
- Drums are consumed one way and never return
- Maximum internal volume per footprint matters most
- Existing automated handling assumes a cylindrical body

What is a conical steel drum?
A tapered steel drum that nests when empty, so the empty leg stops costing what a cylindrical drum costs.
LearnWhy are some drums tapered?
The taper is not styling. It is what lets empty drums nest instead of shipping air.
LearnHow do empty containers affect freight cost?
Rigid packaging is efficient in one direction. The other direction is where the money leaks.

TermConical drum
A tapered steel drum shaped so empty units nest inside each other.
TermNestable
Empty units sit inside each other, so empties take much less space than fulls.
TermOpen-head drum
A drum with a fully removable lid, closed by a ring and clamp.
TermReturnable packaging
Packaging designed to come back and be used again, usually within an agreed loop.
