Meigu cage is a common trade name for the warehouse cage; together with butterfly cage, warehouse cage and Qiaogu cage they basically mean the same product — a foldable, stackable metal-mesh turnover container. The different names mostly come from regional habits and manufacturer branding; when buying, do not get confused by the names — focus on structure and parameters.
In product form, a standard Meigu cage consists of a wire-mesh panel, metal frame, folding hinges, stacking feet and a bottom forklift slot. Empty it folds to save space; loaded it stacks four layers. It is essentially identical to a warehouse cage in material, load and surface treatment; when selecting, judge by internal dimensions, wire diameter, mesh opening and dynamic/static load.
Behind the name difference sometimes lies a specification difference. Some makers call a version with a hollow-board liner, casters or a tow device a 'Meigu cage' while calling the basic foldable cage a 'warehouse cage'; others call export models 'Meigu cage'. When requesting a quote, it is best to send drawings or photos and lock in dimensions and configuration, to avoid same-name-but-different-product.
To judge whether they are the same item, look at four hard indicators: internal length/width/height, wire diameter and mesh opening, load and stacking layers, and surface treatment. Nanjing Tongnuo Warehouse Equipment Manufacturing Co., Ltd., founded in 2013 with a 9,000 m² factory, covers standard warehouse cages and variants with doors, casters and liners, and can match against drawings or sample cages.
One-line conclusion: Meigu cage, butterfly cage and warehouse cage are usually different names for the same container class; when buying, skip the naming debate and compare directly by dimensions, load and configuration — the safest way to avoid the wrong purchase.
