What is the load-bearing capacity range of medium-sized storage shelves
The load-bearing capacity of medium-sized storage shelves is mainly based on single-layer load-bearing as the core indicator, usually ranging from 150kg to 500kg/layer. The specific value will be affected by the shelf structure design, material thickness, layer board type, and span. The breakdown is as follows:
1. Conventional standard medium-sized shelves
Using cold-rolled steel columns (thickness 1.2-1.5mm) and crossbeams (thickness 1.0-1.2mm), combined with cold-rolled steel laminates or grid laminates, the single-layer load-bearing capacity is mostly 150-300kg.
This type of shelf generally has a span of ≤ 2.0m and a height of ≤ 3.0m, suitable for storing daily necessities, electronic accessories, light industrial raw materials, etc. packaged in cardboard boxes and plastic boxes. It is widely used in e-commerce warehouses, small auto parts warehouses, and supermarket back-end warehouses.
2. Reinforced medium-sized shelves
The thickness of the column is increased to 1.5-2.0mm, and the crossbeam is made of thickened steel or double beam structure. The layer board can be reinforced with cold-rolled plates, and the single-layer load-bearing capacity can reach 300-500kg.
The span can be extended to 2.0-2.5m, with a height of ≤ 4.0m, which can meet the stacking needs of heavy goods such as hardware tools, small electromechanical parts, and food raw materials. It is suitable for auxiliary material warehouses and spare parts warehouses in industrial plants.
3. Key factors affecting load-bearing capacity
Deck span: For shelves of the same specification, the larger the span, the lower the single-layer load-bearing capacity. For example, for the same reinforced shelf, when the span is 1.5m, the single-layer load-bearing capacity is 500kg, and when the span is 2.5m, the load-bearing capacity may decrease to 300kg.
Material and process: The thickness of steel plates for columns and beams directly determines the load-bearing capacity. Shelves with excellent welding technology and uniform surface coating have stronger structural stability and actual load-bearing capacity closer to the rated value.
Installation method: The fixation of the shelf to the ground (such as installing anchor bolts) and the firmness of the connection between the layer board and the column will affect the overall load-bearing stability. It is recommended to add additional fixation in heavy load scenarios.
