Racking Shelving

Rack Supported Structure

A decked working surface supported by a rack structure that includes wall girts and roof purlins (or equivalent components) used to support wall and roof cladding. This Rack Supported Structure is designed to carry wind, snow and rain loads in addition to the normal storage rack loads.


A heavy duty storage racking structure built with frames and beams.  It is sometimes referred to as shelving, but the name Racking is used where higher weight capacities for product storage is required.


Redi-Rack is a type of rollformed racking system specific to Canada that uses a bracket, hooks and clips to lock beams and prevent them from rotating.  The post has multiple bends for added load capacity and durability.  Also available in England.


A type of Carton Flow racking system using Mini Roller Tracks.

Roller Conveyor

A series of rollers supported in a frame, over which objects are advanced manually, by gravity or by power. The live roller conveyor is similar to the Gravity Roller, except that power is applied to some or all of the rollers to propel the loads. Roller conveyors can perform accumulation functions that belt conveyors cannot (e.g. the accumulation of tote boxes and cartons).


A process that is used to produce storage rack components for Frame Uprights.  The uprights are then either welded together to form the finished frames using diagonal and horizontal braces, or they are assembled to produce bolted racking.


A Steel Shelving System or drawer system.

Row End Protector (End of Aisle Guard)

End Aisle Guards are structural member attached to, or affixed to, the floor slab, installed adjacent to the ends of pallet rack rows (or in tunnel bays) to protect against impact from material handling equipment.

Rowspacer (row connector)

A member used to connect two aligned frames, one behind the other, ensuring that while joined, they remain separated by a specific distance.  Sometimes used if uprights are arranged in back-to-back rows; Row Spacers are mounted between adjacent columns to ensure that the rows are kept straight and to give the pallet racks even more strength and stability.

Safety Bar

Front to back supports that prevent misplaced pallets from falling between the beams. Safety Bars can be used instead of wire decks for full pallets only but not on the lowest level of tunnel bays. Safety bars usually clip into step beams that have speciality slots in the ledge.  Otherwise, they should be Tek screwed in or bolted to prevent shifting from pallets.

Safety Bolt

Used to securely fasten a beam in place.

Safety Clip

Safety Clips are installed in the beam after it is engaged to prevent the beam from accidently being lifted by lift truck forks.  Clips are installed either in the front or side of the beam bracket and are a required safety element in racking installations.
