A cabinet framework includes a front door frame, a rear door frame, and depth components. The front door frame consists of four first section bars connected end to end. The first section bars are connected by two-way components which includes two sockets with insertion directions perpendicular to each other. The first section bar is a rectangular hollow beam formed by folding a rectangular sheet and is connected to the two-way component by insertion at the socket. The rectangular sheet includes a first edge and a second edge connected together. The first edge wraps around the second edge to form a flange which has multiple rectangular through holes. The rectangular through holes are step holes. The diameter of the holes on the first edge is greater than that on the second edge.
