The invention discloses a guide rod of a lifting column. The guide rod comprises a metal rod body. The metal rod body is the metal rod body obtained by using salt bath nitrogen treatment. The invention further discloses the lifting column. The lifting column comprises the guide rod. The guide rod adopts the above guide rod. The metal rod body obtained by using the salt bath nitrogen treatment is used as the guide rod of the lifting column. Hardness of the guide rod is reinforced, and abrasive resistance, corrosion resistance, fatigue resistance and surface flatness thereof are greatly improved. At the same time, an annular step structure is formed between an upper end and a lower end of the metal rod body. A step surface of the step structure is a smooth flat step surface, so flatness andperpendicularity of the rod body can be guaranteed after the rod body is installed, the lifting column can be normally descended and ascended in a long-term using process, and problems that lifting isunsmooth and noise is large are avoided, thereby later-period maintenance cost of the lifting rod is reduced.
