(1) The materials of warehouse shelves are generally cold-rolled steel profiles, preferably national standards, but few manufacturers use national standards (mainly expensive), so the simplest inspection method is based on the agreed load Force to test.
(2) The structure of warehouse shelves. The structure of the column of the shelf depends on whether the bending of the cross section becomes more and more uniform, and the more uniform and symmetrical the shelf, the better the structure. The crossbeam of the rack depends on the hook structure of the crossbeam and the form of the crossbeam hanging on the column: the more hooks on the crossbeam, the better, and the greater the force, the better; hang the hook of the crossbeam on the column to see if the contact between the hook and the column is close and consistent. The inner side of the hook should be close to the side of the column without gaps, so that the structure can be stable, stressed and durable.
(3) The welding process must be based on the uniformity and fullness of the joints, and there must be no indirect welding or leakage welding.
(4) Surface treatment of warehouse shelves. The spraying treatment of the shelf should be uniform and strong adhesion. Whether the spraying on the surface of the Guangzhou shelf is uniform, and whether the inner edge of the shelf hole is omitted. If it falls off easily, it means the shelf is easy to rust.
