A warehouse cage is a common unit-load tool in logistics turnover, widely used in automated warehouses, production shops, and logistics distribution centers. A warehouse cage - also called a storage cage, butterfly cage, metal cage, folding cage, warehouse turnover cage, logistics cage, or wire cage - is indispensable in storage and transport. Its strengths: 1. Metal-reinforced structure keeps cages stacked stably on top of each other. 2. Multi-point spot welding keeps the cage sturdy and durable. 3. Reinforced hinge structure strengthens the hinges. 4. Spiral hinges fold the cage flat when idle, cutting occupied space. 5. The bottom U-channel is welded for reinforcement, holding up the load. 6. A special foot structure keeps the cage stable when stacked to height. 7. Bent metal handles sit naturally in hand and open and close easily. 8. A latch structure lets the door open even when cages are stacked, for easy access. Size, wire diameter, and mesh spacing can all be built to customer needs, and non-standard warehouse cages can be made to special requirements.
