What are the most common sizes of foldable warehouse cages? Here is a quick rundown. A collapsible wire mesh cage, also called a storage cage, keeps goods fixed, neat and visible, makes stocktaking easy, and raises storage-space utilization. It is durable, ships conveniently, and is reusable, which cuts labor and packaging costs for warehousing companies. The most common design size is 1000*800*840mm, with a wire diameter of about 5.8mm, a 50*50mm mesh, and a load capacity of about 1000kg. This traditional mid-size is the model most companies buy. Across dimensions, load capacity, transport suitability and turnover rate, it fits the needs of most users — the right size is the one that fits. Besides the standard A-5, two other regular sizes cover different needs: A-3: outer 800*600*640mm, wire diameter about 5.8mm, 50*50mm mesh, load capacity about 700kg. A-7: outer 1200*1000*890mm, wire diameter about 5.8mm, 50*50mm mesh, load capacity about 1300kg. How to choose: light goods, narrow aisles, and more cages per footprint point to the A-3. Heavy goods, big batches, and pairing with standard pallets point to the A-7. If you are unsure, start with the A-5 — it is the safest default.
