Shelving Capacities - What is UDL?

Racking Capacity DiagramUniform distributed load (UDL) is a phrase commonly used by shelving suppliers to help explain how much weight can be safely stored on each shelf section. Uniform distributed load dictates that products should be stored evenly with no single point handling excessively more load than the remainder of the shelf.

Stating a UDL value is essential as the weight capacity of any shelf is reduced if loaded unevenly, spreading the load correctly across the whole width of the shelf greatly reduces the stress placed on beams and uprights - this allows the maximum load to be safely applied.

When you see the UDL value stated on any racking or shelving product description, you should use this to evaluate if the selected item is appropriate for your storage needs. If you feel you will be storing items close to the UDL level then it is recommended that you upgrade your choice to a product with a higher capacity to reduce the chances of overloading.
