Modern automated storage and retrieval systems (AS/RS) are no longer speculative capital investments; they are the operational backbone of high-throughput global supply chains. At UNARCO RACKING, we engineer the physical steel interface that dictates the speed, accuracy, and mechanical longevity of multi-million-dollar automation systems.
In a standard distribution center, pallet rack serves as passive storage where lift truck drivers accommodate minor beam deflections and operational misalignments. In stark contrast, automated storage and retrieval systems operate within fractional-millimeter margins. High-speed unit-load cranes moving at 400 meters per minute and multi-directional Autonomous Mobile Robots (AMRs) cannot compensate for thermal racking expansion, baseplate slippage, or torsional beam deflection.
For nearly 70 years, UNARCO RACKING has engineered warehouse storage systems that withstand the most extreme industrial conditions. An AS/RS rack superstructure serves simultaneously as a dense material storage matrix, a kinetic track guide for robotic shuttles, and in many rack-supported building topologies, the structural load-bearing skeleton for the exterior building envelope itself.
By producing both heavy-duty structural steel channels and high-precision roll-formed sections, UNARCO RACKING delivers hybrid automated storage systems engineered to dissipate robotic vibration, comply with strict building code seismic design categories (SDC A through F), and maintain 100% positional repeatability over decades of continuous 24/7/365 operations.
Match your facility clear height, SKU density profile, and throughput velocity with our field-tested automated storage and retrieval system structural topologies.
Engineered for high-bay single or double-deep automated crane storage exceeding 40 meters in clear height. Heavy structural steel columns absorb extreme mast sway, emergency braking inertia, and high seismic moments with minimal lateral deflection.
Optimized for food, beverage, and cold storage logistics. Deep storage lanes integrate precision continuous rail runners for semi-automated or fully automated 4-way robotic shuttles, maximizing cubic storage density by eliminating operating aisles.
High-speed, split-case carton and plastic container storage frameworks. Featuring micro-adjustable shelf beams and high-rigidity uprights engineered for swift goods-to-person order fulfillment and micro-fulfillment distribution hubs.
The ultimate capital-efficient architectural structure where UNARCO RACKING steel uprights serve double duty: supporting full automated dynamic pallet loads while directly carrying building roof joists, wall cladding, and wind/snow loads.
Comprehensive analysis of market dynamics, engineering shifts, and digital transformation shaping automated warehousing procurement through 2030.
Traditional rigid single-aisle SRMs (Storage and Retrieval Machines) are increasingly complemented by flexible, fleet-managed 4-way robotic shuttles. These systems require rack designs with bidirectional load tracks, zero-tolerance rail continuity across bays, and dynamic vertical transfer hoist integration.
Skyrocketing land valuations and industrial decarbonization targets are driving the procurement of non-illuminated, low-oxygen automated facilities. High-density automated storage and retrieval systems reduce cubic building volume requirements by over 40% and lower ambient thermal cooling loads by 35% in cold-chain environments.
Next-generation AS/RS procurement contracts mandate real-time structural health monitoring. Integrated fiber-optic strain gauges and tri-axial accelerometer sensors embedded directly into critical rack uprights interface with cloud-based warehouse execution systems (WES) to detect micro-settling and seismic displacement.
Global supply chain volatility has made monolithic, hard-to-modify automation systems a strategic financial risk. Procurement directors are favoring modular AS/RS racking frameworks that allow phased vertical additions, modular aisle expansions, and hybrid manual-to-automated upgrade paths as SKU counts scale.

Unlike conventional fork-truck selective racks with generous placement tolerances (±12.7 mm or 0.5 in), an AS/RS rack superstructure operates under mill-level precision (±1.5 mm to ±3 mm total allowable deflection across vertical uprights and horizontal runner rails). UNARCO RACKING manufactures to strict RMI / ANSI MH16.1 specifications, deploying pre-engineered laser-guided jig fixtures, structural tie-ins, and precision shimming protocols to ensure zero machine-to-steel interference.
Seismic engineering for automated storage and retrieval systems requires multi-modal response spectrum analysis. We engineer specialized floor-anchorage base plates, dynamic moment-resisting connections, heavy-gauge bracing frames, and energy-dissipating top ties connected directly to the crane runner guide structure, dampening resonance and maintaining track alignment under dynamic lateral loads.
Yes. As one of the few single-source manufacturers producing both hot-rolled structural steel channels and cold-formed roll-formed profiles, UNARCO RACKING often designs hybrid AS/RS frameworks. Structural steel is implemented at lower-level bays and heavy load-transfer nodes where impact resistance and concentrated forces are highest, while roll-formed precision profiles populate higher vertical tiers to optimize steel weight, total load on foundations, and overall project cost.
Depending on regional labor costs, land acquisition expenditures, and SKU velocity, a properly engineered AS/RS rack system typically achieves full capital amortization within 24 to 48 months. Payback is driven by a 40% to 60% reduction in real estate footprint, 70%+ savings on lift truck labor, zero lighting or heating overhead in dark automated environments, and virtual elimination of product and rack impact damage.
Procurement and engineering teams should prepare detailed unit-load characteristics (maximum/minimum pallet dimensions, pallet overhang, bottom board orientations, weight distributions), crane or shuttle acceleration/deceleration thrust loads, facility clear heights, geotechnical concrete slab compressive strength and thickness, and local site seismic design categories.
