Terms You Should Know: Roll-Formed and Structural Pallet Rack
There are two types of pallet rack construction: roll-formed racking and structural racking. While the two variations have similarities, we want to take a minute and explain what makes the two different!
What is Roll-Formed Pallet Racking?
Roll-formed pallet rack is the most common construction of racking. Typically, this type of racking is usually manufactured in the “teardrop” style. The style of the teardrop refers to the teardrop-shaped holes on the columns of the uprights. It is cold-rolled and typically features a rivet connection. There are few circumstances in which the roll-formed rack has a bolted connection.
Pallet racks in the roll-formed style also tend to be less expensive because it is constructed with less steel than structural racking. Roll-formed racking uses mounting clips that allow storage areas to be easily adjustable to different heights according to load size. This flexibility is beneficial for warehouses that store a wide variety of product sizes.
What is Structural Pallet Racking?
Structural pallet rack is different than roll-formed pallet rack in that it is created from hot-rolled steel. In structural racking, components are traditionally bolted together, which is how one can easily spot structural versus roll-formed pallet rack. The horizontal load beams connect to the uprights with bolts, which still allows for an adjustment, but just not as easy as with teardrop rack. Structural rack also typically has a higher weight-bearing capacity.
Structural pallet rack is made of thicker steel c-channels, making it the more expensive but durable pallet rack option. It is most commonly used in warehouses where inventory has a quick turnover because durability is a huge factor when accommodating busy forklift traffic.
