Each of the cross beams is connected to a corresponding support portion by a connector, and a side face of each of the cross beams has a rest face for placement of a corresponding rest portion. At least two opposite ends of the rest portion are arranged on the rest faces, in the same plane, of at least two corresponding cross beams. The plurality of cross beams and the plurality of support portions are profiles formed by die extrusion-stretching. Compared with a traditional shelf, the shelf according to the present invention has the advantages of light weight, having less tendency to rust and corrode, being easy to disassemble and assemble, being free of stress concentration problem, and the like.
