RMIRack Manufacturers Institute

RMI is the industry standard-bearer for storage rack. Its members are the manufacturers who produce pallet rack, and they collectively develop and maintain ANSI MH16.1 — the structural design standard that governs how rack is engineered, tested, and rated in the US. When you see rack that's 'RMI compliant,' this is what they mean.

Why RMI Membership Matters

  • RMI members manufacture rack to ANSI MH16.1 standards — the national structural benchmark
  • RMI publishes the load capacity testing protocols that determine how much weight rack can safely hold
  • Buying from an RMI member gives you confidence that the product has published, tested load ratings
  • RMI's rack inspection guidelines are the basis for most professional inspection programs
  • Insurance carriers and building departments reference RMI standards when evaluating rack safety

Membership Requirements

RMI membership is limited to companies that manufacture industrial storage rack. Members must agree to manufacture product in accordance with ANSI MH16.1 specifications, participate in independent product testing, and publish accurate load capacity data. This isn't a pay-to-play membership — there are actual product standards attached.

Frequently Asked Questions

Is it important to buy rack from an RMI member?
It's the strongest quality signal in the industry. RMI members are committed to manufacturing rack that meets ANSI MH16.1 — the national standard for rack structural design. Their products have published, tested load ratings. Non-RMI rack isn't necessarily bad, but you lose the assurance that comes with the standards commitment. Most building departments and insurance carriers reference RMI standards.
What is ANSI MH16.1?
It's the American National Standard for the design, testing, and utilization of industrial steel storage racks. Developed and maintained by RMI under ANSI oversight, it covers structural design, load testing, seismic requirements, and installation standards. When your building department asks for 'code-compliant' rack, this is the standard they're referencing.
Does RMI inspect or certify individual rack installations?
No. RMI sets standards and publishes guidelines, but doesn't inspect or certify specific installations. They do publish rack inspection guidelines (the 'Guidelines for the Assessment of Damaged Rack' document) that professional inspectors use. Some inspection companies are trained under RMI's program, but the inspection itself is performed by independent professionals, not by RMI.
