| Basic Definition | Reusable metal storage and transport container | A collapsible wire mesh container is made from welded steel wire panels, a base, corner posts, and folding side sections. It is designed to hold, move, store, and return materials efficiently. |
| Common External Footprint | Approximately 800 × 600 mm to 1,200 × 1,000 mm | The footprint is selected to match pallets, shelving bays, forklifts, and available warehouse space. Larger models may use footprints close to 1,200 × 1,200 mm. |
| Typical External Height | Approximately 600–1,000 mm | Height depends on the intended load and stacking configuration. Lower units are often used for small parts, while taller units provide greater volume for bulky goods. |
| Mesh Opening | Commonly about 25 × 25 mm to 100 × 50 mm | The opening size affects visibility, ventilation, containment of small items, and overall weight. Smaller openings help prevent smaller components from falling through the sides. |
| Wire and Frame Material | Welded low-carbon steel wire and formed steel sections | Steel provides the rigidity required for repeated handling. The frame normally carries concentrated loads while the wire panels provide containment and visibility. |
| Surface Finish | Electro-galvanized, hot-dip galvanized, or painted steel | Zinc coatings improve corrosion resistance. Painted finishes can provide additional protection and visual identification, but suitability depends on the operating environment. |
| Typical Load Capacity | Approximately 500–2,000 kg per container | Capacity varies with base construction, wire diameter, container dimensions, load distribution, and stacking requirements. The manufacturer's rated working load should always be followed. |
| Folded Height | Often reduced to about 15%–30% of the assembled height | The side panels fold inward or down onto the base, creating a compact nested package. The exact folded height depends on panel thickness, hinges, and the folding sequence. |
| Folding Mechanism | Hinged side panels with locking pins, latches, or drop gates | When assembled, the panels are raised and secured to the corner posts or adjacent panels. Releasing the locking hardware allows the sides to fold onto the base in a controlled sequence. |
| Typical Folding Sequence | Remove or release the top restraint, unlock the side panels, fold the ends, then fold the long sides | The precise order depends on the design. Operators should keep hands and feet clear of hinge points and confirm that all panels are fully locked before loading. |
| Stacking Capability | Commonly 3–5 loaded units, subject to design rating | Stacking legs, corner posts, or locating sockets transfer the load vertically. Stacking must be performed on a level surface and within the specified working-load limit. |
| Empty Return-Space Reduction | Often approximately 60%–85% less volume than assembled containers | Folding empty containers reduces truck, trailer, and warehouse space requirements. The actual saving depends on the folded height and the number of units nested together. |
| Handling Equipment | Forklift, pallet truck, or lifting equipment with compatible entry points | Many designs include fork-entry channels or reinforced base members. Forks should be fully inserted and centered before lifting to reduce tipping and frame damage. |
| Access Features | Drop-down gates, hinged doors, or removable panels | Access openings allow operators to retrieve goods without unloading the entire container. Gate height and position should match the stored material and handling process. |
| Visibility and Ventilation | High visibility and continuous airflow through the mesh walls | The open structure makes contents easier to identify and inspect while allowing air circulation. It does not provide weatherproof or dust-tight protection without additional covers. |
| Typical Applications | Automotive components, fabricated parts, warehouse picking, recycling, and returnable logistics | The containers are suitable for durable goods and parts that benefit from reusable handling equipment, clear visibility, ventilation, and efficient empty returns. |
| Main Advantages | Reusable, stackable, space-saving, visible, and durable | Their folding structure reduces return logistics costs and storage volume, while the rigid steel construction supports repeated use in industrial material-handling environments. |
| Important Limitations | Not inherently waterproof, airtight, or suitable for every load type | Loose, very small, corrosive, or weather-sensitive materials may require liners, trays, lids, or a different container design. Sharp loads must not exceed the mesh or base limitations. |
| Safe Operating Practice | Inspect the base, mesh, hinges, locks, and stacking points before use | Do not use containers with cracked welds, bent posts, damaged locking hardware, or unstable bases. Keep loads evenly distributed and never exceed the rated working load. |
