Before purchasing a steel material box, think through three questions: what the box holds, where it is placed, and how it is turned over. The outer dimensions of the material determine the box's length, width and height; the storage method determines whether stacking feet or a folding structure are needed; the handling method determines whether forklift slots, lifting lugs or casters are required. Once these three points are settled, discussing specifications will not go off track.
Common steel material boxes use a frame structure: the bottom is welded from steel panels and support legs, while the four sides can be corrugated plate, flat plate or wire mesh panels. Corrugated-plate side walls are strong and suit heavy loose loads; mesh side walls are open, easy to count through and lighter; for material that must be sealed to prevent spillage, steel-plate side walls are recommended. Posts are usually square tube or angle steel, with hanging lugs often welded at the top for stacking or lifting.
Load capacity is the key to selection. It is recommended to leave a safety margin for the actual full-load weight, generally using 80%-90% of the rated load. Whether stacking feet are welded at the four corners of the box, whether the bottom frame is reinforced, and how thick the side steel plate is all directly affect how many layers can be stacked. Regular boxes can stack 2-4 layers, depending on the strength of the bottom frame and floor conditions.
If you need custom sizes and load capacity, please provide Nanjing Tongnuo Warehouse Equipment Manufacturing Co., Ltd. (tel +86 025-84935609) with the material length, width and height, the weight per box, the number of stacking layers, and whether forklift or lifting is used. We will produce design drawings and manufacture to order, supporting sampling for confirmation before bulk supply.
