What Is a Collapsible Cage Pallet and How Does It Contain Heavy Metal Parts Without Cardboard?
Sebox
Sebox collapsible cage pallet: Q235A structural steel frame, mesh or steel-plate doors, 1000kg reference load, foldable for reverse logistics. Built for automotive, machining, and closed-loop buyers.
A Collapsible Cage Pallet Built for Heavy Metal Parts
Sebox is a foldable steel pallet box engineered for automotive, machining, and closed-loop logistics buyers who need to contain heavy metal parts without relying on cardboard.
Where a standard flat steel pallet only gives you a deck, Sebox adds a full perimeter cage: a reinforced base plus a front gate, side gate, and an optional auxiliary gate. The structure is assembled from quality carbon structural steel tubing using full-penetration welds at the joints and bolted connections between modules, so the stillage is rigid under load yet can be unbolted for replacement or export packing. For each door and the base, mesh panels or steel plate are selected according to the part profile to prevent spillage and drop-through.
- Base + front gate + side gate (+ auxiliary gate) assembled with full welds at steel joints and bolts between modules
- Q235A carbon structural steel tube frame; doors and base select mesh or steel plate to suit the part
- Static powder-coated finish (default blue) for indoor warehouse and production-floor use
- Stackable when loaded by forklift or crane; folds flat when empty to cut return-trip volume
- Reference static load up to 1000 kg per unit when used as a stacked stillage (project-dependent)
Three Sebox Builds Buyers Actually Use on the Floor
Build A
All-Mesh Four-Sided Cage Pallet
Four welded mesh sides plus half-drop front gate for visual inventory of small machined parts, fasteners, and stampings.
- Doors & base: welded wire mesh on all four sides
- Best for: machined parts, fasteners, small stampings
- Handling: forklift pockets on the base frame
Build B
Mixed Mesh + Plate Floor Cage
Mesh sides for visibility, steel plate on the base and lower rails to catch sharp blanks, oily scrap, and falling swarf.
- Doors: mesh upper / steel plate lower
- Base: reinforced steel plate against swarf damage
- Best for: CNC blanks, oily parts, scrap collection
Build C
Closed-Loop Export Pallet Stillage
Folds flat for reverse logistics and sea-container return, then rebuilds on the customer line for repeated trips.
- Doors: mesh or steel plate per part
- Folding: collapses to roughly 1/3 of working height
- Best for: closed-loop, sea-container export, tier-1 supplier loops
Why a Sebox Cage Pallet Beats Cardboard and Flat Pallets
Cage vs. Flat Steel Pallet
A standard flat steel pallet only carries a deck. Sebox adds a perimeter cage — base + front gate + side gate (+ auxiliary gate) — so heavy metal parts cannot slide off the fork deck during transit, lifting, or cornering. The cage is the load-security surface, not just packaging.
Why Cardboard Cannot Carry Heavy Metal
Corrugated boxes crush under concentrated metal weight, absorb oil and coolant, lose strength when wet, and fail European Gitterbox / heavy-industry safety expectations. Sebox uses Q235A structural tubing and bolted modular panels, so the box itself becomes the load-bearing structure instead of the contents.
Containment that Prevents Drop & Spill
Doors and base are specified per part — wire mesh for visibility and ventilation, steel plate for sharp blanks, oily swarf, or scrap. The half-drop front gate allows picking from a lower layer even when the stillage is stacked three high, so operators are not climbing onto stacks.
Fold-Flat Return, Stack-Full on Outbound
Empty Sebox units fold down and stack on top of each other to cut reverse-logistics volume; loaded units stack three-high under forklift or crane handling. One container out, one collapsed container back — without re-buying packaging each trip.

Share part size, weight per piece, units per batch, oil / coolant exposure, and whether you need mesh or steel-plate doors. Our team reviews fit for your line.
Select Reference Build
We map your profile to Build A (all-mesh), Build B (mesh + plate floor), or Build C (closed-loop export) and confirm base dimensions, gate layout, and finish.
Confirm Spec & Drawing
You receive a dimensioned drawing with load rating, door swing, and forklift-pocket position. Adjustments are folded in before tooling moves to production.
Production & Container Loading
Sebox units are welded, bolted, powder-coated (default blue), folded, and container-loaded for export. Spare bolts and gate latches ship with the order.
Buyer Questions on Sebox Cage Pallets
How is Sebox different from a flat steel pallet?
A flat steel pallet is only a load deck — no sides, no gates, no containment. Sebox adds a full perimeter cage: a reinforced base plus a front gate, side gate, and an optional auxiliary gate, so heavy metal parts cannot slide off during forklift moves, crane lifts, or cornering.
Why won’t cardboard work for heavy metal parts?
Corrugated cardboard crushes under concentrated metal weight, absorbs oil and cutting fluid, loses strength when damp, and does not meet heavy-industry / European Gitterbox safety expectations. Sebox uses a Q235A carbon steel tube frame so the container itself is the load-bearing structure, not the contents.
How does the cage actually prevent parts from falling?
Each door and the base are specified by part profile: welded mesh for small stampings and fasteners where visibility and ventilation matter; steel plate on the base or lower rails for sharp blanks, oily swarf, or scrap. The half-drop front gate also lets operators pick from a lower layer while the stillage is stacked, so no one climbs on the stack.
Can Sebox be stacked with a forklift or crane?
Yes. Loaded Sebox units are designed to stack three-high under forklift or overhead-crane handling. Reference static load is up to 1000 kg per unit when used as a stacked stillage; project-specific ratings depend on part weight, dimensions, and stacking height.
What does the surface finish look like?
Sebox ships with a static electrostatic powder-coated finish, default blue, suited to indoor warehouse and production-floor use. Other RAL colors are available on request for fleet identification.
Is Sebox a one-size-fits-all product?
No — Sebox is a reference build system. Final dimensions, mesh vs. plate selection, and gate layout are configured to your part, batch size, and handling method. This page describes the reference main version, not a single universal SKU.
Can the cage be disassembled for export or repair?
Steel joints are full-penetration welded for rigidity, while modules (gates, base frame, side panels) are bolted together. Bolted connections can be unbolted for replacement panels, gate swaps, or export packing, then reassembled on site.
How does Sebox cut reverse-logistics cost?
Empty Sebox units fold flat and stack on top of each other, typically reducing return-trip volume to roughly one third of the working footprint. For closed-loop automotive and tier-1 supplier flows, this means one container out and one collapsed container back, without re-buying expendable packaging.
Where do I get pricing and lead time?
Pricing depends on dimensions, mesh-vs-plate selection, finish, and quantity, so it is not published on this page. Submit your part size, batch weight, and destination port through the inquiry form and our team will return a quotation with lead time.
