A shelving board is used in conjunction with a bracket or rack in a shelving system, for carrying items. The shelving board comprises a board body and a connecting piece. The board body may be a hollow structure or a recessed-and-raised structure, to reduce the material consumption and reduce the cost without affecting the strength. The connecting piece is used to hinder a relative movement between the board body and the rack or between the board body and the bracket, so as to improve the stability of the shelving board. The shelving board may be made by an extrusion process and cut into any length as required. Shelving boards may also be made into prefabricated pieces by an injection molding process, which are spliced into a desired length by means of splicing portions processed on the shelving boards.

A shelving system comprises a horizontal beam, a vertical beam, a bracket, a rack, and a position-limiting piece. The vertical beam is slidably connected to the horizontal beam, the bracket is detachably connected to the vertical beam, the rack is in contact with an upper edge of the bracket, the position-limiting piece is detachably connected to the bracket through a gasket, and the position-limiting piece is connected to the bracket and can prevent the rack from moving relative to the bracket. In the present application, the strength of a connecting part between the bracket and the vertical beam is enhanced by the gasket, and the stability of the bracket and the rack is increased by the position-limiting piece, thereby improving the goods carrying capacity of the shelving system as a whole.
