Storage rack for steel plates of multiple sizes

The invention discloses a storage rack for steel plates of multiple sizes. The storage rack consists of longitudinal beams, stiffening beams, upright columns, cross beams and skid-proof hooks; each longitudinal beam and the corresponding stiffening beam are fixedly connected through a bolt; the longitudinal beams and the stiffening beams are mutually perpendicular; the longitudinal beams and the stiffening beams are separately arranged in multiple groups, and are arranged in parallel at an equal interval; each upright column is fixedly arranged at middle positions of the corresponding longitudinal beams and is perpendicular to the longitudinal beams; each upright column is fixedly provided with the corresponding cross beams; and each longitudinal beam is provided with the corresponding skid-proof hooks. The storage rack disclosed by the invention is simple in structure, reasonable in design and low in manufacturing cost, can be used for storing the steel plates of multiple sizes, and is capable of expanding s
