16) Double deep rack

A racking system that is used where a greater storage density is required. It accommodates two pallet loads stacked back-to-back and requires special fork trucks called reach trucks.

17) Modular mezzanine

A standardized, pre-fabricated mezzanine structure built in "packaged"/"off the shelf" sizes, loading capacities and spans. Usually limited to lighter PSF (pounds per square inch) capacities and rapid delivery and rapid installation are benefits of the modular mezzanine.

18) Drive in rack

This type of rack utilizes upright frames, rails, and ties to allow a vehicle to enter a storage rack structure from one side only and pick up or deliver pallets on continuous rails.  Drive-in rack is used to address repetitive products and serves to take advantage of cubic space available for storage, when such unit loads do not lend themselves to block stacking.

19) Push back rack

Utilizing wheels in the rack structure, this rack system allows palletized goods and materials to be stored by being pushed up a gently graded ramp.  Stored materials are allowed to flow down the ramp to the aisle.  This rack configuration allows for deep storage a each rack level.

20) Rack supported building

A complete independent storage rack system which is the basic structural system of a building.  A storage or warehouse facility in which storage rack functions as the structural support for the roof.

21) Pallet flow rack

May be considered back-to-back selective rack.  Inclined conveyor wheel sections are installed in the rack enabling back-loaded pallets are allowed to flow by gravity to the front or pick face.  Pallet flow rack is useful for the movement of fast-moving items and serves to increase density of storage and throughput.

22) Storage racks

A single or multi-level structural storage system that is utilized to support high stacking of single items or palletized loads.

23) Cantilever rack

A rack, utilizing "arms" cantilevered from columns, used where there is a need for a full clear shelf that can be loaded from the front without obstruction from rack support uprights.

24) Portable rack

Self contained steel rack units made up of bases and/or decks and posts.  Portable rack may be welded or collapsible units either having a knockdown feature which can be a space saver when units are not in use.

25) Structural rack

Steel storage rack made from hot rolled steel shapes, generally conforming to the requirements of AISC, such as angle, beams or tubing.

26) Selective rack

Steel storage racks arranged in either single or back-to-back (double) rows.  Each of the rows offers a bay or number of bays in the down aisle direction.  Pallets are generally positioned side-by-side in the down-aisle direction at each level of the bay.  The advantage to this configuration of rack is that all pallets are accessible from the facing aisle.

27) R- Mark

In 1998, the members of the Rack Manufacturers Institute (RMI) voluntarily chose to cause conformance to RMI 97 and any successor documents(s) to be a condition of membership in the Association. In 1999, the members of RMI agreed to a certification process administered through a panel of independent Registered Professional Engineers.  Certification requires the submitter to demonstrate a working knowledge of RMI 97 including delivering evidence of various physical tests needed to compute frame and beam load tables. Upon satisfactory completion of the Certification Process, the submitter is awarded a license to apply a unique registered R-Mark to designs.  The R-Mark is only applied by a Licensed Professional Engineer along side of his/her PE seal. The process is open to all rack manufacturers.  RMI encourages specifiers and users of Industrial Steel Storage Rack to consider the value of R-Mark certification when applying racking solutions.

28) Pallet racks

A single or multi-level structural storage system that is utilized to support high stacking of single items or palletized loads.

29) Rack Association

The Rack Manufacturers Institute, Inc. is an independent incorporated trade association affiliated with the Material Handling Industry.  The membership of RMI is made up of companies which produce the preponderance of industrial storage racks.

30) Unit Load AS/RS

Machines that store large loads (usually 1,000+ pounds), typically on pallets with storage rack structure, reaching 100 feet or more tall.
