Cantilever shelving is an important type of shelving. Cantilever shelves are suitable for storing long materials, circular materials, boards, pipes, and irregular goods. Cantilever shelves can be single-sided or double-sided, and they have the characteristics of structural stability, good load-bearing capacity, and high space utilization. Cantilever shelving columns are often made of H-shaped steel or cold-rolled steel. Cantilevers are made of square tubes, cold-rolled steel or H-shaped steel, and the connection between the cantilever and the column is plug-in or bolted. The connection between the base and the column is bolted, and the base is made of cold-rolled steel or H-shaped steel.
