Description

Steel frame for pallet

The present invention relates to a steel frame for pallets, and more particularly, the upper frame and the lower frame are mutually coupled using a column member, and a plurality of column members are configured between the upper frame and the lower frame to provide overall strength of the steel frame. It relates to a steel frame for pallets that can improve the efficiency of storage, transport and operation by reducing the weight of the steel frame.

In general, pallets used in industrial sites are used as a storage support to prevent various loads from being scratched or damaged on the ground, and have a structure that can be transported by a forklift while the loads are loaded.

The frame used for these pallets is made of various materials such as wood, synthetic resin, and metal depending on the use.

On the other hand, in recent years, when a load is loaded on a pallet, many steel frames have been developed to improve the strength of the pallet in relation to the weight of the load, and the structure is also varied and used.
