Steel pipe bed frame and production process thereof

The invention relates to a steel pipe bed frame. The steel pipe bed frame comprises a base, a first supporting seat, a second supporting seat and a third supporting seat. The first supporting seat, the second supporting seat and the third supporting seat are hinged in sequence. When the steel pipe bed frame is in an unfolded state, the upper end faces of the first supporting seat, the second supporting seat and the third supporting seat are located on the same horizontal plane and located above the upper end face of the base. When the steel pipe bed frame is in a folded state, the first supporting seat and the second supporting seat are bent to form a backrest, and the third supporting seat forms a cushion and abuts against the upper end face of the base. The invention further relates to a production process of the steel pipe bed frame. Passivation treatment is conducted multiple times before and after welding, the passivation effect is good, and the anti-corrosion effect is good. The steel pipe bed frame has
