pallet rack components

Pallet rack components

Here is a rundown of key pallet rack components, including a definition of terms used in the material handling business. These industry terms are used by vendors of rack products like this one:

Anchor Bolt: Anchor bolts are inserted through the baseplate’s holes to attach the column to a concrete floor.

Base Plate: A metal plate attached (usually welded) to the bottom of the racking frame columns. This anchors the rack system to the floor and distributes the weight of a column. Also known as footplates or footpads.

Back Connector: (TBA)

Beam: A beam is a horizontal part of the pallet racking. They are the part of the rack on which pallets are slid onto.  They are of steel and come in various types and lengths.

Beam Connector: (TBA)

Beam length: (TBA)

Column (Post): A vertical upright usually made of steel that is a key component of pallet racking.

Keyhole: Upright frame columns feature rows of punched holes, called keyholes, used to attach pallet rack beams to uprights. These keyholes vary in shape, depending on the racking maker.

Flue Space: Flue spaces are unobstructed vertical lines of sight from the floor to ceiling in rack storage areas. There are two types of flue spaces:

  1. Transverse flues: These flues are the spaces between rows of storage in the direction of loading.
  2. Longitudinal flues: These types of flues are the spaces between rows of storage perpendicular to the direction of loading, with a width of up to 24 inches or 600 mm.

Horizontal Bracing: (TBA)

Row Spacer: Row spacers are the components that attach between rows of pallet racking.  A row spacer stabilizes the pallet rack frame and help prevent movement.

Upright: Uprights are the vertical pieces of the pallet rack that hold everything together.  They come in both standard strength and heavy duty versions. They are also called frames.

Upright depth: The horizontal distance measurement between two column uprights in a pallet racking system.

Upright height: The vertical height measurement of a column upright, a critical component of pallet rack.

Wire deck or decking: Wire deck is a pallet rack accessory. It is made from a metal mesh that fits between the front and rear rack beams and provides a floor to place containers or other non-palletized inventory. The wire mesh is open enough to allow water and light to come through, but it acts as a foundation for cartons, cases, and other product containers.

Standard adjustable pallet rack

Standard adjustable pallet rack: Definitions

Definitions for standard adjustable pallet rack

Terminology as it pertains to standard adjustable pallet rack. See the definitions of key components below as illustrated in this exploded view of standard adjustable pallet rack.

Chipboard cladding – Chipboard sheets that act as a horizontal floor on a pallet rack bay.

Chipboard support beams – These appliances hold chipboard in place.

Coil cradle – Also called Coil Beds, they are are designed to fit on pallet rack systems to store drums safely.

Drop over steel panels – These are steel panels that provide a level surface for storing non palletised product on the pallet racking system.

Drum Chock – This is a racking accessory that stops stored drums from rolling.

Forklift clearance bar – A fork or forklift clearance bar make placing  items on your pallet rack beams safer and easier. These are used when you are storing non-palletized inventory with a flat bottom on your pallet rack. Since there isn’t a pallet, and the inventory is flush with the beams, forklifts can’t get underneath the load to pick it up. So the fork clearance bars lift the flat stock up a few inches off the beam to create space.  This allows the forks to pick the inventory up.

Frame – This is the steel skeleton of the pallet rack and consists of beams and columns.

Pallet support bar – These are used to create  a support surface for pallets and stillages (product containers). They are attached to beams across the frame depth.

Row spacer – These secure uprights together in a back to back row. They add stability to  pallet rack. They also keep it consistently spaced. Row spacers are an accessory item for pallet rack. They are used to securing back-to-back rack rows of selective pallet racking.

Splice kit – These join two uprights together to form a longer upright. Splice Kits can be used where the full length upright may not be available and 2 shorter uprights of suitable strength are available. A Splice Kit generally consists of:

  • Splice Plates: Splice plates are pieces of steel that conform to the inside profile of the upright.
  • Bracing Blocks: Bracing blocks sit in between the splice plates to ensure a snug fit.
  • Nuts and Bolts: These are include to hold the entire kit together.

Upright protector  – floor mounted – This rack protection appliance is designed to absorb collisions energy before a truck makes contact with rack frame.

Upright protector – column mounted – This rack protection appliance is attached to columns. They are filled with foam and is designed to absorb collision energy.

Welded footplate – This footing is welded to the frame and is bolted to the floor.
