Factory-direct high-density storage, dynamic carton roller beds, and automated handling solutions manufactured to European CE and ISO 9001:2015 precision standards.
How dynamic roller beds transform manual carton picking into a continuous, ergonomic, high-throughput First-In-First-Out (FIFO) material handling operation.
Carton flow racking—often designated across Central Asian logistics facilities as gravity feed roller racking or live carton storage—is an engineered dynamic storage solution designed specifically for split-case picking, tote handling, and rapid piece-picking environments. Unlike static industrial shelving where operators must expend considerable travel time walking down multi-level picking aisles, carton flow systems leverage a slight decline angle (typically between 2.5° and 4.5°, or roughly a 3% to 6% gradient) across precision-machined roller tracks or skate wheel beds. Cartons, plastic totes (KLTs), and returnable bins are loaded from the rear replenishment aisle and smoothly glide forward under controlled gravitational force to the front discharge picking face.
From an industrial engineering standpoint, carton flow racking achieves two foundational supply chain objectives: the absolute physical segregation of stock loading activities from manual order extraction, and the automated maintenance of a strict First-In-First-Out rotation. This separation completely eliminates operator congestion within narrow picking corridors, reduces order-picker foot travel distances by up to 75%, and compacts overall warehouse floor footprint requirements by up to 40% compared to traditional selective shelving.
The operational reliability of carton flow tracks relies on fine-tuning the balance between rolling friction coefficients and carton mass. High-density polyethylene (HDPE) or zinc-plated steel rollers mounted within cold-formed galvanized C-channels are calibrated based on carton base rigidity. For corrugated cartons prone to bottom deflection under high ambient humidity, our engineers specify closely spaced roller centers (30mm to 45mm pitch) to prevent bottom 'sagging' and track stalling.
Full-depth sheet steel lane dividers prevent SKU cross-contamination during transit. At the discharge picking face, tracks can be outfitted with horizontal pick trays, downward-tilted presentation shelves (15° to 20° ergonomic tilt), or impact-absorption stop plates. These presentation trays expose the interior of the container to picking personnel, accelerating item selection and supporting error-free integration with digital Pick-to-Light (PTL) arrays.
Carton flow beds engineered by HEDA Shelves can be mounted directly into dedicated freestanding flow shelving units or integrated beneath heavy-duty pallet racking uprights (Pallet Flow & Carton Flow combo). This hybrid format allows bulk reserve pallet stock to be stored on upper beam levels, directly feeding the manual carton picking roller levels below, achieving total vertical cubic efficiency.

Tailoring gravity flow storage solutions to the rapid logistics renaissance, high-throughput fulfillment hubs, and industrial modernization initiatives in Uzbekistan.
The Republic of Uzbekistan is currently undergoing an unprecedented transformation into Central Asia’s primary logistical crossroads. With the realization of large-scale infrastructure undertakings, including the China-Kyrgyzstan-Uzbekistan (CKU) Railway and dry port expansions around Tashkent, regional warehouse demand has pivoted sharply away from rudimentary ground-stacking toward high-density, automated, and dynamic order-picking systems. Carton flow racking systems represent a high-ROI upgrade path for Uzbek supply chain operators seeking European-grade picking velocity without the prohibitive capital expenditure of full automated retrieval robotics.
Platforms such as Uzum Market, ZoodMall, and major regional retail distributors operating across Tashkent and the Sergeli logistics zones handle tens of thousands of varied SKUs daily. Carton flow beds integrated into multi-tier picking mezzanines allow high-speed batch picking, eliminating aisle congestion and compressing order turnaround times to meet same-day delivery mandates.
Under the regulatory frameworks of the Agency for the Development of the Pharmaceutical Industry of Uzbekistan, Good Distribution Practice (GDP) requires absolute batch control and strict chronological FIFO release. Our stainless steel roller tracks and sanitizable powder coatings guarantee that medicines, ampoules, and temperature-sensitive health supplies roll forward strictly in order of expiration date.
In the manufacturing corridors of the Fergana Valley (Asaka automotive clusters) and Samarkand commercial vehicle plants, carton flow racks are engineered as lineside feeder systems. Small-to-medium stamped components, fasteners, wiring harnesses, and sub-assemblies glide directly to the assembly technician’s fingertips, establishing seamless Just-In-Time (JIT) production.
At the Navoi Free Industrial Economic Zone (FIEZ), air cargo consolidators and cross-border 3PLs process transshipment freight moving between East Asia and Europe. Carton flow racking creates ultra-dense kitting and sorting buffers where transit cargo can be segregated by air pallet container without tying up wide floor areas.
Designing industrial racking systems capable of withstanding Central Asian seismic fault lines and acute seasonal temperature differentials.
A primary structural failure factor in imported racking across Uzbekistan stems from standard European or South-Asian designs that ignore localized tectonic loads. The Tashkent basin, Samarkand, and the surrounding Fergana ring sit in seismically active geological zones governed by national construction standard KMK 2.01.03-96 ("Construction in Seismic Regions"), corresponding to earthquake intensities of Magnitude 7.0 to 9.0 on the MSK-64 scale.
Every carton flow and hybrid pallet racking structure exported by HEDA Shelves undergoes computer-aided structural simulation using SAP2000 and ANSYS. We calculate dynamic response spectra, nodal displacements, and base shear forces. Upright sections are cold-rolled from high-ductility Q355B micro-alloyed structural steel, paired with heavy-duty baseplates (minimum 12mm to 16mm thickness) fastened with M16 chemical anchor studs embedded deep into the concrete slab to prevent structural overturning during ground acceleration.
Uzbekistan experiences an arid, extreme continental climate, with winter lows descending to -20°C in northern regions and summer warehouse roof temperatures reaching +48°C. Inferior paint finishes rapidly peel, crack, and permit interstitial rust formation under rapid thermal cycling. HEDA Shelves applies an automated 10-stage pre-treatment regimen: degreasing, zinc-manganese phosphating, pure deionized water rinsing, and high-voltage electrostatic polyester powder coating cured at 200°C for exceptional bond elasticity.
Conventional lubricants solidify in sub-zero winter temperatures, causing dynamic rollers to jam. HEDA specifies low-temperature synthetic lithium greases within all roller track ball bearings (rated down to -40°C). Track expansion joints and slotted mounting brackets are calibrated during CAD layout to absorb linear steel thermal expansion between hot summer afternoons and freezing winter nights.

Authoritative guidance on logistics, customs tariffs, installation mechanics, and localized operational parameters.
Shipments originate at our Guangzhou manufacturing facility, where cargo is containerized into 40ft High Cube (40HQ) containers or open-top rail wagons. Rail containers move via China Railway Express via the Khorgos or Alashankou border crossings through Kazakhstan, arriving at key railway cargo stations in Tashkent: Chukursay (Station Code 720000) or Sergeli (Station Code 723507). Total transit duration from departure to arrival at Tashkent customs terminal averages between 12 and 16 calendar days. We provide container load plans, seal numbers, and daily rail wagon GPS tracking updates.
Yes. Our roller beds are fully modular. We adjust roller pitch (center-to-center distances of 28mm, 35mm, 50mm, or wider) and roller diameter to ensure that there are at least three rollers continuously supporting the carton base at all times. For thin-walled cardboard boxes prone to bottom sag, we configure full-width steel roller tracks; for rigid European-standard KLT totes, multi-track polymer skate wheels or universal ball transfers can be specified. Track lane dividers are fully adjustable along the beam width in increments of 12.5mm or 25mm.
When engineering projects for Tashkent, Samarkand, or the Fergana Valley (seismic zones 7 to 9), our structural engineers run finite element dynamic modal simulations. We calculate the building's fundamental vibration period and ground acceleration parameters specified by KMK 2.01.03-96. To absorb lateral seismic inertia, we specify thicker upright profiles (e.g., Q355B high-tensile steel in place of standard commercial grade), increased horizontal and diagonal bracing patterns, reinforced beam-end connectors with 4 or 5 locking hooks, heavy-duty floor baseplates (minimum 12mm thickness), and M16 chemical resin anchors tested for high pull-out shear strength.
We provide full customs compliance documentation matching Uzbekistan customs declaration requirements under Harmonized System Code 7308.9000 (Structures and parts of structures of iron or steel). Documentation includes Commercial Invoices, detailed bilingual Packing Lists with net/gross weights per bundle, Certificate of Origin (General or Form A), Factory Quality Certificate, CE Declaration of Conformity, and structural calculation reports in English. If our clients qualify for investment project incentives under Uzbek national development programs, our documents align with tariff exemption filings.
HEDA Shelves operates a fully automated continuous pre-treatment and powder coating line. All cold-rolled steel profiles pass through chemical degreasing, ultrasonic cleaning, acid pickling, and micro-crystalline zinc-manganese phosphating before powder application. We use industrial-grade TGIC-free polyester powder, electrostatically sprayed and cured at 200°C for 20 minutes. This creates an 80–110 micron coating with superior mechanical flexibility, impact resistance (50 kg/cm), and adhesion ratings (Cross-cut test ISO Class 0). The finish withstands severe thermal cycling without micro-cracking, peeling, or corrosion.
Yes. Our carton flow levels can be retrofit into existing selective pallet racking upright frames. By engineering universal drop-in beam brackets or intermediate hanger frames that fit teardrop, diamond, or rectangular column punches (50mm, 75mm, or 76.2mm pitch), our roller levels can be mounted underneath existing pallet storage bays. This creates an efficient split-level picking configuration where bulk reserve pallets remain overhead while lower ground tiers operate as high-density dynamic piece-picking lanes.
Every order ships with a comprehensive bilingual installation manual, 3D exploded assembly diagrams, and color-coded component mapping that enables local mechanical contractors to assemble the systems efficiently. For large-scale projects (e.g., regional logistics distribution centers in Tashkent or multi-tier pick towers exceeding 3,000 square meters), HEDA Shelves can dispatch experienced site supervision engineers to oversee installation, calibrate roller incline angles, verify torque specs, and conduct load tests prior to final handover.
We support standard international trade terms including FOB (Chinese ports/rail hubs), CIF (Poti / Bandar Abbas for sea-land), and DAP (Delivered at Place - Tashkent Chukursay Station). We accommodate major commercial currencies including USD, EUR, and Chinese Renminbi (RMB / CNY), facilitating direct cross-border bank-to-bank settlement. Typical settlement terms consist of 30% T/T advance deposit upon technical CAD drawing approval, with the balance 70% payable against Bill of Lading (B/L) / Railway Consignment Note (SMGS) copies.
