1.The use of raw material.Some illegal businessmen in order to save the cost, adopting the shelves for defect of steel processing and production, although the thickness is the same size, but its capacity is absolutely can not meet the requirements, use for a period of time after the issue will be exposed, general performance for the shelves of bending deformation, the phenomenon of serious still may rupture.
2. The production process are detailed enough.Some shelf factory production is not rigorous, a small detail processing is not good also may be the cause of shelves bending deformation, such as cutting punch size is not accurate, installation is inconvenient may leads to layer shelf tilt, to store the goods in such a case, may be caused by uneven shelves bending deformation, even the shelves layer board, column fracture.
3. The goods are not bearing deposit as required.Each shelf design, manufacturers will calibrate shelves of bearing range, if the actual storage of goods, more than shelves of maximum load, or violate the principle of shelves safe use and are likely to cause shelves bending deformation.
4. The forklift many collisions.In a few large warehouse shelves, even as it has reasonable set the anticollision column shelves fence, forklift truck is still unable to avoid collisions with shelves, quality pass the shelves in a short period of time may not happen bending deformation, over time, shelves are likely to be bending deformation occurs.
