Many customers ask how a foldable warehouse cage differs from a regular one. In fact, the foldable warehouse cage is the same product; it simply folds, stacks, has upper and lower front doors, and a galvanized surface, and the name just states those features up front. As a foldable warehouse cage manufacturer, Xintongnuo regularly supplies three standard specs (units in mm): A3: external 800*600*640, internal 760*570*500, wire 6, mesh 50*50, load 700kg, volume about 0.22 cubic meters, leg height 100. A5: external 1000*800*840, internal 960*770*700, wire 6, mesh 50*50, load 1000kg, volume about 0.52 cubic meters, leg height 100. A7: external 1200*1000*890, internal 1160*970*750, wire 6, mesh 50*50, load 1200kg, volume about 0.84 cubic meters, leg height 100. If these three standard sizes do not fit your materials, Nanjing Tongnuo Storage Equipment Manufacturing Co., Ltd. can also build non-standard foldable warehouse cages to order.
