Conical Steel Drums

Conical Drums: Nestable Steel Drums

Nestable steel drums that stack full and nest empty.

The nestable alternative to standard and reconditioned steel drums.

Tapered steel drums designed to nest inside one another when empty, which cuts the space and freight cost of returning or storing empties. Used for decades in juice concentrate, purée and paste applications, and increasingly for viscous chemical products.

Same Operation. Smarter Empty Drum.

If your operation already uses straight-wall steel drums, moving to conical drums does not require reinventing how you handle steel drums. When full, they perform much like the steel drums you already know — filled, closed, handled, stacked, stored, palletized and transported using familiar industrial practices.

They are not simply “export drums.” The fundamental difference is the geometry: a controlled expansion toward the top lets empty drums nest inside one another.

When full: familiar steel-drum functionality.

When empty: dramatically better space efficiency.

That reduces the space required for empty-drum storage, handling and transportation without sacrificing the basic functionality processors expect from a steel drum.

The advantage appears when the drum is empty.

Not every conical drum performs the same way.

With more than 25 years of experience sourcing and evaluating conical steel drums, we pay particular attention to the manufacturing details that affect real-world handling — proper steel preparation, welding, forming, coating and paint curing. One especially important consideration is clean separation after nesting: high-quality coating and manufacturing help drums separate smoothly rather than binding together, making them easier for operators to handle in day-to-day production.

Our focus is simple: reliable drums. Consistent handling. Fewer operational headaches.

The electric car of steel drums

An electric car drives the same roads as any other car. A conical drum works the same way: it does the same job as the metal drums you use today, with smarter geometry.

Same road, smarter engine

Same filling, closing and handling. Smarter geometry.

Fewer fill-ups

5 truckloads instead of 35 for 10,000 empties.

Lower emissions

Up to 35% lower transport CO₂ per drum.

1,900 empty drums. Stop paying to move air.

A cylindrical empty drum is mostly empty space, and you pay to store it and to ship it back. Conical drums nest inside one another, so the same pallet, truck and warehouse bay hold several times more empties. Exact figures depend on the size and configuration you order.

Why it is used

  • Empty drums nest, so return freight and warehouse space drop sharply.
  • Steel handles hot fill, cold storage and long transit without deforming.
  • Widely reused and fully recyclable at end of life.

Typical options

  • ✓Multiple capacities
  • ✓Open head with lever-lock ring
  • ✓Lined or unlined interior
  • ✓Painted or galvanized exterior
  • ✓Pallet configurations to suit your storage

How they are built

  • Body formed from pre-painted steel sheet, assembled after the paint has cured, so the finish does not peel or stick.
  • Galvanized bottom base to keep rust out of the seaming area.
  • Standard lithography: blue enamel outside, pale yellow food-contact epoxy-phenolic varnish inside; see Specifications.
  • Anti-rust exterior paint; BPA-free paint available on request.
  • Cold-rolled steel sheet to EN10130 and EN10131.

Sizes and closures

  • Working capacity around 58 US gal (220 L) or 60 US gal (230 L); other heights available.
  • Body dimensions worked out to load efficiently in standard ISO containers.
  • Galvanized steel cover, plastic cover, or cover with two bungs.
  • Zinc-coated versions available where the shipment is regulated.

Handling and logistics

  • Empties arrive shrink-wrapped in bundles on pallets and come off with a forklift, so unloading is quick.
  • Nesting cuts the space empties take in storage and on return freight.
  • Well-made drums separate cleanly after nesting — coating and curing quality matter.
  • Maximum storage height for full drums depends on body thickness and drum weight; see the full-drum storage limits below.

Reuse and end of life

  • Built to be washed and reused rather than discarded after one trip.
  • Steel is fully recyclable at end of life.
  • New drums avoid the contamination risk that comes with repurposed containers.

One truckload of empties: 6.9× more conical drums, 7× fewer trucks

A 53-foot dry van carries about 2,000 nested conical drums — 6.9 times as many as the roughly 290 straight-sided drums in the same space. For 10,000 empty drums, that is 5 truckloads instead of 35: fewer trucks, fewer pallets, less handling, and up to 35% lower transport CO₂ per drum moved.

Where they are used

Food and ingredient packaging

Packaging for tomato, fruit and vegetable processors

Conical steel drums are used around the world to store and transport liquids, powders and other materials safely. Their tapered walls support familiar industrial handling when full and compact nesting when empty.

They serve food and beverage, agriculture, chemical and manufacturing operations, with configurations selected for the product, process and destination.

Available configurations

  • Aseptic bags for tomato paste, fruit paste and purées
  • Plastic liners and bags for frozen citrus juice
  • Plastic, metal, galvanized or aluminized-steel lid options
  • 55, 58 and 60 US gallon capacities (approximately 208, 220 and 227 liters)
  • Automatic de-nesting compatibility available by configuration
  • Outdoor-storage, collection and reconditioning suitability confirmed for the selected drum and use case

Options and capacities are subject to the selected drum configuration and availability.

Food-contact and compliance requirements

Available drum, lining, lid and bag configurations can be sourced for applicable FDA food-contact, HACCP-program and/or ISO 22000 requirements.

For regulated goods, UN-certified configurations are also available for the transport of hazardous materials, including heavy, viscous liquids and dry goods: UN 1A1 and 1A2 steel drums rated for the applicable Packing Groups, tested and marked for the required performance standards.

Certifications and ratings apply to the selected drum and its manufacturer—not automatically to every configuration. Tell us the product, fill temperature, required UN rating or Packing Group, destination and handling requirements, and we will confirm the correct documented configuration.
