The length and width of a warehouse cage should first align with pallets, rack beams and the inner width of truck compartments, to facilitate forklift work and full-truck loading. Common turnover sizes are mainly in the 800×600, 1000×800, 1200×800 and 1200×1000 mm range, but naming and series differ by manufacturer, so purchase by clear external dimensions.
The height depends mainly on two factors: first, the total height after the cargo is stacked, with clearance left for loading and unloading inside the cage; second, the total height after stacking, determined by the forklift's maximum lift height, warehouse floor height and fire-aisle requirements.
When setting length, width and height, first list the cargo length/width/height, single-piece weight and pieces per cage, calculate the per-cage weight, and then check whether the selected cage load capacity matches—avoid choosing by appearance alone.
Site conditions also affect the size: aisle width determines whether the forklift can handle smoothly, and rack spacing determines whether the cage fits the bay. We recommend measuring the site before setting specs, to avoid the cage not fitting or not being movable after delivery.
Dimensions directly determine material usage and price: larger specs use more material but also raise space utilization. When unsure, send cargo photos and dimensions to the manufacturer, who will recommend specs and a stacking plan, then confirm by sampling.
