Structural Pallet Rack: The Basics
From our Pallet Rack Guide: “Pallet Rack is a material handling storage system engineered to store materials and products that are often palletized or bundled. There are many different styles and manufacturers of pallet racking, but all of these share the same goal of increasing storage density by storing pallets off the ground, utilizing vertical space.” Pallet racking is used in areas like large warehouses, distribution centers, manufacturing plants and other storage facilities. Additionally, there are many pallet racking types, as well as add-on accessories.
Now that you’ve got that down, let’s move to specifics. Standard Selective Pallet Racking is the most common style of pallet rack used in warehouses. All standard selective rack consists of upright frames, cross beams, and wire decking. Within selective racking there are two types of steel used: roll formed and structural. These two main types are often, but not always used in different applications. The differences between the two start with are how they’re manufactured. Roll formed racking is made by rolling and cutting sheets of steel, earning it the name “roll formed”. This type of steel is often used in the manufacturing of racking because it’s optimal for creating lengthy products in large quantities. The way this type of steel becomes stronger is by adding more longitudinal bends to the product. Structural racking, on the other hand, is produced by passing a large chunk of hot steel through a roller to attain a specific shape, such as a C-channel or I-beam. Due to its high strength-to-weight ratio, structural steel is often used in the construction of high-rises.
