Offered as two separate certifications to manufacturers of industrial steel storage racks and of welded wire rack decking, RMI’s R-Mark assures storage rack users that the rack frame, beam and decking capacities shown in a unique design’s load table were calculated in accordance with RMI’s ANSI MH16.1: Design, Testing and Utilization of Industrial Steel Storage Racks or ANSI MH26.2: Design and Testing of Rack Decking. In essence, users of R-Mark storage rack and decking can be confident that their system will perform safely when properly designed, engineered and installed.
R-Mark Created in 1999
RMI’s members created the certification program in 1999. RMI recognized that very few domestic manufacturers make both types of products. Indeed, most consider decking to be an accessory to steel storage racks. Decking used on pallet rack provides additional support for stored material. It also serves as a safety net for unstable loads. Further, because it is fabricated, load calculations for decking are different than those used to design and engineer a storage rack structure. Therefore, RMI developed two certifications.
Uniform Application Process for Certification
Although the load tables and calculations associated with each are different, the process of earning an R-Mark license is the same. A manufacturer submits their design process—including testing, calculations and resulting component capacities—to an independent analysis. Two registered professional engineers with experience and expertise in the design and application of racking systems review the application. This review and approval procedure confirms that the manufacturer performs calculations as specified by RMI/ANSI MH16.1 or the RMI/ANSI MH26.2.
Manufacturers who meet these requirements receive an R-Mark certification license. This entitles them to display the R-Mark on any qualified product designed in the same manner. Certification gives users and owners of industrial steel storage rack and welded wire rack decking products the confidence that their rack and/or decking system’s manufacturer produces a product that meets RMI codes and standards.
Safety the Responsibility of Rack Owner
Regarding safety, one caveat: Given that every project is unique (load types differ, component structure configurations can vary, and seismic codes and requirements are variable), a manufacturer’s R-Mark certification alone does ensure a safe system. Rather, a rack owner must ensure that a qualified engineer reviews the design and calculations for each application. This review verifies that the system design meets RMI design standards that are appropriate for a specific use and job site.
