Stacking refers to stacking commodities regularly to form a stack shape. For some commodities, there is a certain limit on the number of layers that can be stacked on the commodity body to avoid crushing. In this case, a material frame is usually used. Hold the goods, and then stack the material frames with the material frames to form a stack, which reduces the floor space and facilitates storage and transportation.

The existing material frame will have ribs on the sides to increase the strength and avoid deformation of the material frame columns. However, in some cases, such as when the size of the product exceeds the limit, in order to facilitate the placement of the product, it can only be placed on a pair of the material frame. Set up ribs on one side and leave the other side empty or set up a flexible net bag. When there are a large number of products in this type of material frame, the products at high places can easily slide to the side with the ribs, squeezing the frame columns. , causing it to tilt outward. When its tilt angle exceeds the limit, it is difficult to place subsequent material frames stably above it.
