ANSI MH28.2-2018 - Design, Testing and Utilization of Industrial Boltless Steel Shelving
This standard and companion commentary (provided with the standard but not part of the American National Standard) applies to industrial steel boltless shelving; boltless shelving placed on mobile carriages; multi-level boltless shelving systems such as pick modules, catwalks, and deck-overs; and for boltless shelving used in conjunction with an automated storage and retrieval system (AS/RS). The structural framing components for these systems are made of cold-formed or hot-rolled steel structural members. This standard does not apply to the following: industrial steel pallet racks (addressed by ANSI MH16.1), industrial cantilever racks (addressed by ANSI MH16.3), boltless shelving structures not fabricated from steel, industrial steel bin shelving, or shelving systems built with slotted metal angles.
Boltless shelving is typically a hand-loaded, prefabricated, free-standing, building-like non-building structure that utilizes a designed framing system. It is generally located within an industrial or warehouse environment that is restricted from the general public. Personnel working within the confines of the boltless shelving structure are presumed to be properly trained, physically able, and appropriately attired for the intended working environment.
This standard is intended to be applied to the design, testing and utilization of such structures. This standard applies to boltless shelving structures installed within a building and subjected to seismic (earthquake) loads. Loads from environmental exposure, such as snow, wind or rain loads, are not addressed in this standard. This standard does not cover any design requirements that need to be addressed for supported equipment that would subject a shelving system to significant dynamic loading and/or harmonic vibration that has the potential to cause structural damage or metal fatigue. For environmental exposure or applications beyond the scope of this standard, an evaluation by a qualified design professional is required.
