When do the medium-sized shelves in the warehouse need three columns?
The three-column heavy-duty shelf is assembled by upright posts, beams at both ends, middle beams, cross braces, diagonal braces and self-locking bolts, which can effectively prevent the shelf from being unstable after the bolts are loosened. The column is made of Q235B plate by cold bending and rolling, and its cross section is composed of 13 plane. It has the advantages of large inertia distance, strong bearing capacity and strong impact resistance. Because the technology of "automatic punching first and then cold forming" is adopted, the possible failure of the column due to stress concentration is completely avoided. The beams at both ends adopt special cold-rolled P-type closed beams; The structure has the characteristics of simplicity, reliability, light weight, strong bearing capacity and low cost. The middle beam is made of two special C-shaped steel beams, which doubles the thickness of the upper and lower surfaces of the beam. According to the design theory of steel structure, this structure makes full use of the bearing capacity of materials and has the characteristics of light weight, strong bearing capacity and low cost. When the column clamp is connected with the column, it is equipped with a specially designed safety pin, which can ensure that the beam will not fall off under the impact of external force.

Three-column shelves are mainly used in warehouses such as cloth industry, clothing industry and third-party logistics industry. They are mainly suitable for larger, longer and heavier goods. In this case, if the traditional two-row shelf does not have enough load, the back-to-back traditional two-row shelf will waste materials. The three-column shelf is optimized on the basis of two columns, and the columns are assembled by three columns. The three columns are assembled and connected, which makes the shelf more stable and more convenient for the storage and satisfaction of goods.
