What is Beam Deflection
Beam deflection is a common occurrence in pallet rack systems with hefty loads. Below, you will find a practical beam deflection formula to help calculate maximum deflection and determine if your deflection is within the acceptable range. Keep reading to learn more and visit our pallet rack guide for more info on pallet racking.
Beam deflection is the bowing or bending of a beam under heavy capacities. Although it sounds dangerous (and most certainly can be), there is actually a normal and acceptable range for deflection. Our beam deflection formula helps calculate if your beam’s deflection is within the normal range.
For cantilever racking, deflection occurs when the load is placed at the end of a cantilever arm, causing the arm to bend away from the upright column. For typical pallet rack systems, excessive deflection occurs when there is a point load or when loads are too heavy for the pallet rack system.
Again, beam deflection is a natural occurrence and some beam deflection is standard.
