The present invention relates to a grid packing of a distillation column for separating substances on the basis of distillation in petroleum refining, petrochemical and fine chemistry, etc. The embossing process is performed so as to form, and the blocking grooves 3 are formed vertically at the upper end and the lower end of the bent portion of the main body 1. The structure is simple and easy to manufacture. By spreading the material evenly throughout the grid packing, it can maximize the effect of distillation, and also embossing at regular intervals throughout the grid packing to form long grooves for maximum mechanical strength. It is a useful design.
