Manufactured in North America to withstand high-velocity intralogistics. Discover heavy-duty modular racking, high-capacity shuttle systems, and boltless span units engineered for seamless Querétaro warehouse operations.
Carton flow racking—often designated as live storage or gravity flow picking—is an engineered dynamic storage solution tailored for fast-moving items, split-case picking, and high-velocity kitting. In Querétaro's rapidly expanding manufacturing corridors, where floor space premiums in Class-A industrial buildings command top dollar, static shelving systems create substantial operational friction.
By leveraging slightly inclined roller tracks, carton flow separates restocking replenishment from the active picking face. Totes, corrugated cartons, and plastic containers are introduced from the rear replenishment aisle and advance downward by natural gravity to the front discharge station, establishing an uncompromised First-In, First-Out (FIFO) inventory stream.
Querétaro sits at the nexus of the NAFTA/T-MEC industrial corridor along Federal Highway 57. From El Marqués to Parque Industrial Querétaro (PIQ), carton flow systems power mission-critical assembly and fulfillment nodes.
Querétaro's automotive belt (hosting brands like Tremec, Brose, TRW, and Magna) relies on carton flow for Just-In-Time (JIT) and Just-In-Sequence (JIS) line-side assembly. Gravity tracks hold standard returnable plastic totes (KLTs), ensuring hardware, wiring harnesses, and stamped components glide continuously to the assembler's reach.
Surrounding the Querétaro Intercontinental Airport (AIQ) in Colón, aerospace giants (Bombardier, Safran, ITP Aero) mandate rigorous aerospace trace-level picking. Custom carton flow lanes incorporate full-width divider plates and barcode lockouts to prevent component cross-contamination and guarantee exact hardware lot rotation.
Situated strategically along the Mexico City–Querétaro artery, major logistics hubs and 3PL mega-fulfillment centers integrate carton flow racks within multi-level mezzanines (Pick Towers). Integrating carton flow beneath selective pallet buffers triples pick face density for cosmetics, consumer tech, and apparel split-case sorting.
Compare mechanical throughput, floor area utilization, capital investment payback, and ergonomics for medium-to-high velocity piece picking operations.

As USMCA cross-border trade accelerates, the industrial landscape of Querétaro faces unprecedented structural shifts. Discover the micro-trends shaping high-density storage procurement.
Industrial real estate absorption in Querétaro's Central and Airport submarkets has driven Class-A lease rates above historic averages. Facilities can no longer afford wide, empty aisles; vertical cube optimization via carton flow levels beneath pallet positions is now mandatory.
Automotive components moving across the Laredo and Colombia border crossings require strict batch traceability. Implementing FIFO gravity tracks ensures older lot numbers cannot be bypassed or buried behind newly arrived production runs.
Full AS/RS adoption carries substantial capital investment. Querétaro operators increasingly choose hybrid carton flow modules: combining structural steel gravity roller lanes with autonomous mobile robots (AMRs) and pick-to-light (PTL) boards for maximum flexibility.
Relying on trans-Pacific imports for racking profiles introduces multi-month vessel delays and exorbitant maritime freight. Sourcing racking fabricated from local Mexican manufacturing plants (Escobedo, NL & Mexicali) cuts project lead times by 65%.
Engineering storage systems since 1949. Frazier Industrial combines North American structural hot-rolled channel fabrication with dedicated Mexican production plants to safeguard your capital investment.
Unlike lightweight cold-formed roll-formed steel that easily twists and tears when struck by lift trucks, our columns and load beams are constructed from American-standard structural channels. Structural steel delivers up to 250% higher torsional rigidity and impact absorption.
With operational manufacturing facilities in General Escobedo (Nuevo León) and Mexicali (Baja California), we deliver domestically manufactured structural racking straight to Querétaro within hours, eliminating customs clearance hold-ups and import tariff overheads.
Forklift impacts are an operational reality in fast-paced distribution centers. We back our structural channel systems with an industry-leading 2-year rack damage warranty, supported by modular bolted connections that enable rapid component replacement without tearing down entire bays.
Querétaro lies within seismic Zone B under the Mexican Federal Electricity Commission (CFE) manual. Every carton flow frame is individually engineered per RMI ANSI MH16.1 specifications, providing registered professional engineer calculations to secure municipal construction permits effortlessly.
From 2D/3D CAD concept layout to final anchoring, load capacity signage, and post-installation safety inspection, our bilingual project engineering teams guide Bajío supply chain directors across every project milestone.
Proud standing member of the Rack Manufacturers Institute (RMI), Material Handling Industry (MHI), and the Global Cold Chain Alliance (GCCA). We shape North American storage standards rather than merely following them.
Critical engineering, legal, regulatory, and operational considerations when specifying carton flow and pallet racking systems in the state of Querétaro.
Under Mexico’s federal building regulations, industrial structures must comply with the Manual de Diseño de Obras Civiles (MDOC) - Estructuras issued by the Comisión Federal de Electricidad (CFE), alongside the local Querétaro Municipal Building Code (Reglamento de Construcción para el Municipio de Querétaro). Querétaro is designated primarily as Seismic Zone B (low to moderate seismicity). However, because high-density carton flow pick towers concentrate significant dead and dynamic live loads, installations require specific seismic anchor embedment calculations, certified base plate sizing, and validation against the Rack Manufacturers Institute (RMI) ANSI MH16.1 specification. Our team provides signed calculation memory documents (Memoria de Cálculo) endorsed by a registered Mexican Perito Responsable de Obra to facilitate your local municipal licensing and Civil Protection (Protección Civil) sign-offs.
In high-throughput facilities common to automotive and logistics parks like El Marqués and PIQ, forklift impacts occur regularly. Cold-formed (roll-formed) steel is manufactured from thin-gauge sheet steel bent into open-back channels. A single lateral impact from a counterbalanced lift truck or reach truck can buckle the upright column, compromising the structural stability of the entire rack row and requiring emergency unloading. In contrast, Frazier’s 100% hot-rolled structural channel steel features solid, thick-walled steel corners and heavy hot-rolled flanges. It absorbs forklift contact without catastrophic failure, lowers lifetime structural maintenance costs by over 40%, and is backed by our signature 2-year rack damage warranty.
Yes. Our carton flow track assemblies are engineered to retrofit into virtually any standard industrial pallet racking framework, whether structural or roll-formed. Utilizing universal drop-in hanger brackets and adjustable front and rear support beams, gravity tracks can be mounted at ground level beneath active pallet positions (creating a high-density "pick tunnel"). The roller track beds feature a 50mm vertical slot adjustment pitch, allowing plant engineers to reconfigure lane pitch, lane dividers, and knuckle pick trays whenever carton profiles, SKU packaging, or production sequences change.
By fabricating our structural steel storage systems inside our domestic manufacturing plants in General Escobedo (Nuevo León) and Mexicali (Baja California), we offer unmatched supply chain resilience for projects across the Bajío. Orders delivered to Querétaro do not face maritime shipping disruptions, port congestion at Manzanillo or Veracruz, or prolonged customs brokerage delays. Furthermore, our products fully satisfy the regional value content requirements of the USMCA (T-MEC), ensuring zero tariff friction and clean tax deductions for Mexican corporations and maquiladoras operating under the IMMEX framework.
Standard carton flow shelving at floor level typically requires standard industrial slab capacities of 2,500 to 3,500 kg/m² (approx. 500-700 PSF) with a minimum 150mm reinforced concrete slab. However, if your Querétaro facility is planning a 2-tier or 3-tier pick module (where carton flow levels are built into structural mezzanines spanning overhead), concentrated point loads at base plates can exceed 8,000 kg. Our structural engineers review your facility’s geotechnical report and core sample data to custom-engineer wider seismic base plates and floor anchors, effectively dispersing point loads and preserving slab structural integrity without necessitating costly foundation re-pouring.
Carton flow is the ideal physical backbone for paperless order picking. Our front discharge beams are pre-punched with internal wiring channels and standardized mounting brackets designed specifically for leading Pick-to-Light (PTL), Put-to-Light, and wireless electronic shelf label (ESL) hardware. As items advance forward via gravity, barcode scanners or overhead optical sensors interface with your Warehouse Management System (WMS) (e.g., SAP, Manhattan, Blue Yonder). Light modules flash the exact pick quantity directly above the target lane knuckle tray, driving picker accuracy to 99.98% while slashing onboarding training times for seasonal warehouse staff.
