Conventionally, pallets made of various materials, such as steel, wood, paper, and synthetic resin, have been released. However, steel pallets have excellent durability, but there are many restrictions on weight reduction. There was a weak issue.

In particular, wood pallets have hygroscopic properties in the wood itself, so that various microorganisms or larvae can inhabit the inside of the wood. Therefore, when exported as pallets, the wood pallets move between countries without undergoing the quarantine process of the exporting country. As it may affect problems and ecosystems, regulations on this situation are getting serious.

In addition, the plastic pallet made of a synthetic resin material uses a vacuum molding form during manufacture, but is heavy in weight, expensive, costly and time-consuming to manufacture a mold, and has considerable difficulty in repairing and changing the dimensions.

In addition, the paper pallet is light in weight and easy to change its dimensions, but it causes dents during long-term storage and distribution, and is weak against moisture, and is used with other materials or moisture-proof by wax, paraffin, etc. It has a problem that the weight becomes heavy and recycling becomes difficult.

In order to solve the problems of the conventional pallet as described above, an aluminum pallet is used, but the aluminum pallet is made of expensive aluminum as a whole, resulting in a cost increase. In addition, when reducing the thickness of the parts of the pallet in order to reduce the cost, there is a problem that can not support the load of the load to deteriorate the function of the pallet.

In addition, regardless of the adoption of the above materials, if the pursuit of weight reduction of the product in the design process of the pallet, the overall strength of the pallet occurs, and if the pursuit of high strength increases the weight and the cost of the raw materials increases. Since the price competitiveness of the product is lowered, research on the development of a technology for reducing the weight of the pallet while maintaining strength is still actively conducted.
