Many first-time buyers ask for a “warehouse cage specification table.” What actually sits behind it are four things: structure, materials, accessories, and whether customization is possible. Structure first. Cages are spot-welded from cold-drawn wire mesh panels, with U-channel steel welded to the bottom for support — sturdy and reliable. When stacked, you just open the door on the layer you need, without tipping the upper layers down. On usage. When not in use, cages fold flat and store together, taking very little floor space. You can add PVC liner boards inside so plastic or scratch-prone parts do not get marked. Cages can also mount on a mobile cart or be fitted with caster wheels to act as a turnover trolley. If standard sizes do not match the job — oversized items, special load needs, or going onto racks — special specifications can be customized.
