Load beams (or step beams). Step beams are roll formed members with a step along the top inside edge. This step is used to hold any load support components such as pallet supports or wire decks.

Box beams have no inset step, instead have four flat sides like a box. All load beams typically mount onto an upright frame column with integral rivets or hooks.

Structural beams are used with structural uprights but can be used with standard roll formed uprights. Structural load beams offer heavier weight capacities than step beams or box beams.

Upright columns (upright frames) vary in size and design depending on load requirements, and styles. The most common are open-back roll-formed upright columns. Upright frames can also be constructed utilizing structural C shapes for columns with increased weight capacity.

Diagonal braces and horizontal braces, commonly referred to as upright frame lacing is usually welded between two upright columns to form selective upright frames.

Pallet supports are roll formed channels that are placed front to back between the load beams to support pallets on the pallet racking.

Wire decking is used as a safety measure on pallet rack systems to prevent pallets or the products stored on them from falling through the rack structure. Wire mesh decking comes in various thicknesses and mesh dimensions.

Footplates, also known as footpads or baseplates, are at the base of columns and serve as anchors to give the rack more stability. Anchor bolts are inserted to the attach the column to the concrete floor.
