The maximum weight capacity of a standard pallet rack is approximately 5,000 lbs. Although larger pallet racks may differ in terms of weight limitations, they will have a label showing how much each rack can handle.
The 5,000-lb. weight rating reflects a standard tubular pallet rack. Other designs, such as upright pallet rack frames vary, as stated by its application. This is due to several factors, such as the vertical air space between the levels. If there is less vertical air space, the pallet rack is able to hold more weight. This means that the items being stored are closer together, so the weight is less likely to impact the structural integrity of the pallet rack.
