Price: $150.00The purpose of this standard is to specify the minimum requirements for the structural design, testing, and utilization of industrial steel cantilevered storage racks. A cantilevered rack is a storage system designed to store long, bulky, or irregular materials of almost any length. Cantilevered racks generally consist of freestanding columns connected to fixed bases that are anchored to the floor. Load arms cantilever from the column to create storage levels, with loads placed directly onto the arms. Columns are spaced to adequately support loads.
Price: $50.00This standard is established to provide a guideline for design, testing, fabrication, and utilization of industrial storage rack decking utilized as an accessory for industrial steel storage racks that conform to ANSI MH16.1, Design, Testing, and Utilization of Industrial Steel Storage Racks. Storage rack decking is placed on beams of industrial steel storage racks to create a surface on which to place materials that can be on pallets, in containers, or in some other form.This standard applies to uniformly loaded storage rack decking applications, as well as various concentrated and partially distributed loading conditions common to storage rack applications. Storage rack decking can be fabricated from welded-wire mesh with permanently attached reinforcements, metal bar grating, composite engineered wood, corrugated metal, perforated sheet metal, or other materials that meet the performance requirements for use in storage racks.This standard does not apply to:Storage rack decking manufactured prior to date of adoption of this standard;Storage rack decking that has been improperly installed, altered, damaged, or used in any manner other than that for which it was originally intended, designed, purchased, sold, or a combination thereof;Lumber not graded or stamped by the Southern Pine Inspection Bureau (SPIB), West Coast Lumber Inspection Bureau (WCLIB), or equivalent grading agency; orStorage rack decking that is intended to support any loads other than product loads (e.g., moving, or live, loads due to walking or stepping).
Price: $175.00 (a $25.00 savings)This combination package includes the following two American National Standards:ANSI MH16.1-2023, Design, Testing, and Utilization of Industrial Storage RacksANSI MH26.2-2023, Design, Testing, and Utilization of Industrial Storage Rack Decking
Price: $150.00This standard specifies minimum requirements for the structural design, testing, and utilization of industrial steel storage racks. It applies to industrial steel storage racks, movable-shelf racks, rack-supported systems, and storage racks associated with automated storage and retrieval systems (ASRSs; also known as “stacker racks”), constructed of cold formed and/or hot-rolled steel structural members. Such rack types also include push-back rack, pallet flow rack, case-flow rack, pick modules, and rack-supported platforms. This standard is also intended to be applied to the design of the storage rack portion of any rack structure that provides support to the exterior walls and roof, except as noted. It does not apply to other types of racks, such as drive-in or drive through racks, cantilever racks (see ANSI MH16.3 for guidance on cantilever racks), portable racks, or racks made of material other than steel.ANSI MH16.1-2023 replaces ANSI MH16.1-2021, which was a revision of ANSI MH16.1-2012(R2019). It updates seismic provisions to align with ASCE/SEI 7-2022, including use of software to obtain seismic data and new methods to obtain the seismic response coefficients. It also includes revisions to the cantilever testing provisions and to the cyclic beam-to-column testing provisions in this section, so that either test can be used to determine beam design spring constants.A summary of the major revisions between the 2021 and 2012 revisions include the following:Reorganization of the document to align with guidance in ISO/IEC Directives, Part 2, specifically moving requirements previously in Section 1 elsewhere in the document, adding Normative References to Section 2 (previously Section 10, “References to the Text”), and adding Terms and Definitions to Section 3 (previously “Nomenclature” in the Foreword);A requirement for post-installation inspection conducted by the owner;New stability design requirements similar to the requirements in ANSI/AISI S100 or ANSI/AISC 360 replace the effective length method for stability design outlined in previous editions;Seismic provisions (7.4) were revised to align with ASCE/SEI 7-2016, including revision of redundancy factors for multiple rows and revision of the Fa and Fv coefficients for the D-Default site class;New design procedure for perforated columns that includes a new definition of net section using reduced strips to represent the hole lines. Torsional properties are now to be calculated using rounded corners and a distortional buckling check is required for those sections subject to distortional buckling. The equation for the Q effect on the column strength has changed;New section on pallet support design;New section on frame tie and cross-aisle tie design; New provisions for base plate and anchor design where the seismic overstrength consideration is required;Interpretation of the cyclic tests for connectors has been added; The base fixity test and frame bracing test have been added;The portal test and the upright frame test in the 2012 revision were removed from the 2021 revision.
Pushback racking gives Denali the high-density storage it needs, providing more pallet positions and requiring fewer aisles. The new racking uses the FIFO (First In First Out) inventory system – commonly used in the food industry. A pushback storage rack can offer up to 90% more storage space than traditional selective pallet racking.
When Central Steel & Wire (CS&W), a high-quality metal products and services supplier, decided to move from the Chicago facility that had been its home for 80 years, it envisioned creating a state-of-the-art product depot and service center that used the industry’s most efficient material handling technology. It would be a major transformation for CS&W because the company was leaving behind a labor-intensive method of material handling in favor of using automated guided vehicles (AGVs) to move its wide range of metal products.
The beverage distributor faced various challenges, including ensuring scalability for SKU inventory and meeting the usability requirements of existing forklifts, such as minimum aisle widths, lift heights, and clearances.
When a financial company reached out to Jeff Andrews, President of Hammerhead Material Handling, for a new archival storage project that would be warehoused in California’s Inland Empire he knew that finding the right storage system could pose a challenge. "The geographic location is considered a very high seismic area and paper is flammable, so we needed to find a solution that would also meet fire codes.” TubeRack, made by Hannibal Industries, would work.

In this video we'll explore the key points you should consider when preparing for a rack installation.
Rack safety is critical regardless of your geographical location. However, depending on the seismicity of your region and site, safe implementation could be dependent on a completely different set of standards.
Racking is incredibly versatile and can often be reconfigured and/or relocated to suit the needs of an evolving facility - however, it’s important to proceed with caution.
Updated May 2023. This Guideline was developed by the Rack Manufacturers Institute, an Industry Group of MHI and represents suggested practices and considerations for repairing or replacing damaged racks. It is intended to provide useful information and guidance for owners, users, designers, purchasers and/or specifiers of repairs to racks and rack systems. It is advisory only and should only be regarded as a simple tool that its intended audience may or may not choose to follow, adopt, modify, or reject. The following information does not constitute a comprehensive safety program, cannot guard against pitfalls in operating, selecting and purchasing such a system, its repair or its replacement, and should not be relied upon as such. However, such a safety program should be developed, and an independent adviser should be consulted in doing so.
Updated March 2023. The safe and efficient use of racked storage facilities depends on a number of factors. It is with these factors in mind that these considerations have been prepared to give advice to the warehouse operator who may not be a specialist in technical matters or in the detail design related to the storage facility. These considerations are intended to give an indication of good practice. They are not intended to be comprehensive, and where the user is in any doubt, or where this document does not appear to cover fully the particular situation being considered, then the user must consult the supplier or other sources for specialized technical advice.
This document contains detailed examples on how storage rack designers can apply the formulas and guidance found in ANSI MH16.1-2023 in their designs and calculation packages.
The late Dan Clapp, former Chairman of RMI’s Engineering committee discusses rack safety and why it is so important. RMI had two presentations at MODEX this year and you can listen to both of them on MHI Cast.
