RMI is The Rack Manufacturers Institute, an incorporated trade association formed in 1958. The membership of the RMI is made up of suppliers of industrial steel storage racks and related structural systems, each who must pay a fee to be a member of the RMI.

RMI is an affiliated trade association of MHI and is the American National Standards Institute (ANSI) accredited developer of product and safety standards for U.S. industrial steel storage racks and welded wire rack decking.


MHI, which stands for  the Material Handling Institute, is a material handling, logistics, and supply chain association incorporated in 1945 with the objective of promoting the industry at large. MHI is a sponsor of the ProMat and MODEX events.


ANSI, which stands for the “American National Standards Institute”, is the coordinator of the U.S. private sector, voluntary standardization system. The ANSI Federation of is made up of nearly 1,000 U.S. businesses, professional societies and trade associations, standards developers, government agencies, institutes and consumer and labor interests, all working together to develop voluntary national consensus standards.

ANSI itself does not develop standards; the federation accredits qualified organizations, whose standards development process meets all of ANSI’s requirements, to develop American National Standards.

ANSI is one of several design agencies engineers use to design and engineer racking systems. Others are:

AISI-(American Iron and Steel Institute)-Cold formed steel shapes AISC-(American Institute of Steel Construction)-Hot rolled shapes AWS-(American Welding Society)


RMI created the R-Mark Certification Program as a way for storage rack users and customers to identify that rack frame and beam capacities shown in a load table were calculated in accordance with “the new standard,” ANSI MH16.1-2012 Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks.* The ANSI specification is the standard that rack engineers defer to when designing storage rack.

While all RMI members have voluntarily agreed to be guided by the ANSI standards and to participate in the R-Mark Certification Program, RMI is not the recognized building code governance. IBC (International Building Code), ASCE (American Society of Civil Engineers), and UBC (Uniform Building Code) address the specifications listed above, but R-Mark is not required by building codes.

It’s important to note that while the RMI administers the R-Mark Certification Program, products can still be in accordance with the recognized standards without bearing the R-Mark. To be certain your pallet rack meets the specifications, ask your manufacturer or dealer – they can provide documentation.

All Next Level rack products meet or exceed ANSI MH16.1-2012 Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks

*While a standard IS a technical expression of how to make a product safe, efficient, and compatible with others, a standard alone cannot guarantee performance. Conformity assessment, however, provides assurance to consumers by increasing consumer confidence when personnel, products, systems, processes or services are evaluated against the requirements of a voluntary standard.
