What is a warehouse cage? It is also called a butterfly cage or metal returnable container. Dimensions are standard and capacity fixed, so the goods inside are visible at a glance and stocktaking is quick. It works on the factory floor, as display and storage in a supermarket, and outdoors. Warehouse cages are used widely: die castings, forgings, auto parts, motorcycle parts, hardware stampings, construction machinery parts, metal products, pipe fittings, gears, plumbing and bathroom parts, lighting, furniture, logistics, catering and food. The improved cage goes on racking, runs along production lines, and stacks; wheeled units move around the workshop, and PVC- or steel-lined units stop small parts from falling out. Common sizes: A-3 800*600*640mm, 50*50mm mesh, 6.0mm wire diameter, load capacity 800kg A-5 1000*800*840mm, 50*50mm mesh, 6.0mm wire diameter, load capacity 1200kg A-7 1200*1000*890mm, 50*50mm mesh, 6.0mm wire diameter, load capacity 1500kg The standard sizes are 800*600*640, 1000*800*840 and 1200*1000*890.
