Top 15 Pallet Rack Manufacturers in USA in 2025

How this list was built—and how to use it

This neutral rundown weighs engineering depth (RMI/ANSI conformance), breadth of rack systems, U.S. manufacturing footprint, automation-readiness with asrs systems, and after-sales support for order fulfillment and ongoing operation.

Plain-English definition: An ASRS (automated storage and retrieval system) uses shuttles, cranes, and software to automatically handle pallets, totes, or cartons. Unit load (unitload asrs) and miniload asrs target pallets and totes, respectively. Autonomous mobile options (AMRs) can feed aisles. A pallet shuttle moves within deep lanes; a shuttle lane system can be fully automated or semi-automated depending on the operation.

Top manufacturers (A–Z): credibility snapshots & product strengths

Known for deep engineering and broad software-hardware alignment. Their selective pallet racking page states these racks provide direct, individual access to all loads and are easy to maintain—ideal for high-SKU inventory and high-velocity order profiles in a balanced system. For automation roadmaps, the brand supports automated storage and storage retrieval flows with cranes or a pallet shuttle where density is key, dovetailing with asrs systems configurations that scale by aisle and axis.

Selective racking is the most popular and versatile storage system, enabling direct access to every pallet appears on the page linked above, making it suitable where operation rules require 100% selectivity.

Backed by Nucor steelmaking, NWS manufactures structural, roll-formed, and patented TubeRack. Their product pages for structural rack and selective rack give clear design intent for abuse resistance and selectivity. Nucor’s acquisition record—Elite Storage Solutions following Hannibal—expanded capacity and coverage, reinforcing national availability and seismic expertise. For automated storage, NWS integrates with asrs systems and lane-based pallet shuttle options to boost storage retrieval density in freezer operations and peak-season order fulfillment.

Steel King’s SK2000 and structural lines emphasize impact resistance and fast installation; the brand underscores boltless tubular frames with rugged geometry that handle forklift abuse. Their resources section references engineering around cold-storage, seismic, and operation uptime—good fit when a site plans phased upgrades toward automated storage and eventual asrs tie-ins.

A structural-rack leader with multi-plant footprint across North America. Frazier’s product family spans selective, push-back, drive-in, pallet flow, and pick modules—an ideal toolkit for freezer buildings and heavy-duty operation cycles. Structural beams/uprights excel where impact is frequent and where asrs cranes or pallet shuttle lanes demand tighter tolerances for reliable retrieval.

Ridg-U-Rak’s pallet rack systems include slotted, teardrop, and structural designs. Their capacity statement cites major U.S. manufacturing throughput, which matters when timelines are tight and order volumes are seasonal. Pick modules aid carton flow and order fulfillment where a hybrid of case picks and pallet moves run in the same system.

UNARCO’s product catalog covers roll-formed and structural racks plus deep-lane flow, drive-in, push-back, and engineered pick modules. For operation leaders, this breadth simplifies hybrid designs where reserve pallets ride above active pick faces and inventory moves follow FIFO via pallet flow—clean handoff for storage retrieval targets in food and beverage networks.

Advance focuses on structural rack at scale. Their pages for pallet-racking solutions and structural rack show emphasis on high-density push-back, pallet flow, and pick tunnels—prime for freezer and e-grocery order peaks. The brand also pairs semi-automated pallet shuttle lanes with selective aisles to elevate cubic yield without hurting retrieval speed.

Speedrack’s portfolio covers selective, push-back, pallet flow, and engineered systems, with content outlining application fit for each. Their selective-rack guide highlights adjustability and access—good alignment with AMR-fed aisles and future asrs integration during brownfield expansions where aisle geometry and the crane travel axis must be preserved for storage retrieval reliability.

RBI designs and manufactures industrial racking with attention to seismic and freezer applications. RBI’s engineering-led approach helps de-risk later asrs add-ons by keeping deflection limits tight so crane handoffs and shuttle interfaces land right the first time—an operation safeguard that always pays off.

SpaceRAK, now part of Heartland, manufactures pallet rack, platforms, and safety gear. Their product pages (e.g., pallet racking and platforms) and independent overviews confirm sustained investment in engineered systems. Deep-lane and pick-module options suit beverage and 3PL operations that require dependable storage retrieval during peak order spikes.

Husky’s Invincible® teardrop rack stresses cross-compatibility, Bowlock safety clips, and U.S.-sourced steel—handy for fast expansions where mixed teardrop fleets exist. That design reduces changeover friction for inventory moves while keeping the system safe under heavy cycle counts.

Bulldog manufactures selective, structural, and cantilever racks. Their structural rack note emphasizes resistance to forklift abuse—important where operation KPIs depend on high uptime and where a future asrs link or pallet shuttle lane will run in parallel for buffer staging.

NAS provides pallet racking across North America with engineering support for large capital builds. Their product pages and organization overview describe configurable systems for complex inventory profiles, with the structural rigor useful for asrs and AMR feeding. Cross-border coverage supports U.S. networks with multi-site harmonization of specs.

Beyond automation, SCHAEFER’s U.S. pages on racking systems and pallet flow outline manual to fully automated paths. Their line supports FIFO pallet flow, mobile pallet racks, and integration with cranes for high-density storage retrieval within staged operations.

NEDCON runs U.S. manufacturing in Shelbyville, KY. Their pages for pallet racking and automated pallet racking describe compliance with U.S./EU standards and clear migration paths toward crane-based asrs and pallet shuttle lanes. This helps design teams keep the crane travel axis and clearances consistent from day one.

While not a rack frame maker, Nashville Wire is pivotal to many projects because decking and supports dictate load distribution and safe operation. See their wire decking and pallet supports pages for options that improve visibility, order picking safety, and beam capacity alignment—key details in food and consumer-goods order fulfillment.

Buying checkpoints that actually move the needle

1) Load capacity & beam spacing

Insist on stamped calcs per ANSI MH16.1 and RMI. Define unit load (pallet + product) weight, worst-case deflection limits, and beam spacing—this is the first answer engineering needs for a safe system. For deep-lane with pallet shuttle or push-back, confirm dynamic factors for retrieval impacts during peak operation.

2) Aisle geometry, MHE, and future ASRS

Protect the crane travel axis in your layout now if you plan to migrate to asrs later. Choose uprights and frame bracing that preserve clearances for mast sway and rail tolerances; confirm that frames, baseplates, and anchors will accept future loads from unitload asrs and miniload asrs subsystems feeding order areas.

3) Automation alignment

Ask each vendor to map how their racks will interface with shuttle technology, crane handoffs, AMRs (autonomous mobile), and WMS tasking for storage retrieval. If a fully automated day-two is likely, spec welded reinforcements and tighter tolerances now—cheaper before bolting down beams.

4) Seismic & cold storage

In high-seismic zones or freezers, structural frames often outperform roll-formed under abuse. Cross-check manufacturer literature (e.g., Nucor’s structural and TubeRack guidance) and demand site-specific calcs. Verify impact energy paths and column protection for forklift interfaces during heavy operation.

5) Lifecycle cost & service

Support programs and lead times matter when inventory turns climb. Ask about quick-ship beams, deck compatibility, and certified installers. Engineering audits keep systems safe as product lines change and order profiles evolve.
