From heavy-duty roll-formed selective frameworks to automated radio-controlled shuttle vehicles, our manufacturing facilities produce certified, precision-engineered warehouse storage systems tailored to high-throughput commercial and industrial applications across Sri Lanka.
High-load axle-supported cantilever framework engineered for heavy cable drums, wiring rolls, and industrial coiling setups with easy rotational payoff access.
Robust Q235B/Q355B structural steel pallet racking with customizable upright frame depths, high capacity box beams, and anti-corrosive powder finish.

Modular light-to-medium manual order-picking rack with drop-in steel or MDF deck panels, ideal for SKU staging, spare parts, and fulfillment centers.
Engineered for high vertical clear heights and Very Narrow Aisle (VNA) access, optimizing warehouse cube space up to 85% volumetric density.
Extra-duty industrial storage racks designed for severe duty cycles, featuring reinforced bottom column wraps, seismic baseplates, and high impact tolerance.
Versatile wide-span bay architecture allowing continuous horizontal hand loading for bulk cartons, textiles, fast fashion apparel, and loose raw stock.
Independent 2-way and 4-way micro-controlled pallet shuttle bots equipped with laser positioning, obstacle detection sensors, and LiFePO4 power cells.
In modern industrial logistics, the radio pallet shuttle racking system represents a monumental leap over traditional static storage. As a semi-automated deep-lane storage solution, the system utilizes an autonomous, self-powered carrier vehicle—the Radio Shuttle—that travels along integrated zinc-coated guide rails inside racking storage tunnels. Forklift trucks never need to enter the deep storage lanes. Instead, a standard counterbalance or reach truck positions the shuttle into the designated lane channel and delivers unit loads to the tunnel entrance.
Optical laser alignment sensors, photoelectric safety eyes, and precision stepper drives automatically position each pallet with millimeter accuracy. This decoupled structure solves the critical engineering bottleneck that plagues traditional Drive-In racks: excessive forklift travel times, structural frame collisions, and compromised vertical storage ceilings.

Our shuttle carts run on high-capacity, quick-swap Lithium Iron Phosphate (LiFePO4) battery packs, sustaining continuous 8-to-10 hour operational shifts. Intelligent handheld wireless radio remotes or integrated Warehouse Management System (WMS) industrial tablet controllers direct FIFO (First-In, First-Out) or LIFO (Last-In, First-Out) sorting, continuous auto-compacting, and selective pallet counting without human intervention inside the rack matrix.
Sri Lanka's geographical positioning along major East-West maritime trade lanes has transformed the island into South Asia's preeminent transshipment hub. However, rising industrial land costs in the Western Province, high commercial electricity tariffs, and intense coastal humidity demand specialized warehouse racking engineering.
Warehouses surrounding the Port of Colombo (Peliyagoda, Kelaniya, Wattala) face severe real-estate constraints and steep per-square-foot leasing rates. Pallet shuttle racking allows logistics operators to compress multiple container consolidation lanes into high-density 30-meter continuous tunnels, maximizing vertical clearance up to 18 meters without requiring specialized ultra-expensive VNA turret trucks.
Sri Lanka's flagship export apparel manufacturing sector operates on relentless seasonal turnover and just-in-time delivery for global brands. Our high-density shuttle and longspan systems store raw textiles, fabric rolls, and finished boxed garments in organized batch channels, slashing staging congestion and enabling rapid pick-and-pack loading cycles directly to export containers.
Given the high power tariffs in Sri Lanka, cold store operators in Negombo, Galle, and Colombo must maximize cubic refrigeration efficiency. Our low-temperature radio shuttles are designed with internal condensation heaters, low-viscosity synthetic lubricants, and cold-rated electronics that operate seamlessly down to -25°C, reducing wasted thermal volume by up to 50% compared to selective rack setups.
Evaluating warehouse storage systems requires balancing capital expenditure against volumetric storage density, forklift operational labor, and operational safety risk.
| Racking Architecture | Volumetric Space Density | Pallet Selectivity | Material Handling Speed | Structural Collision Risk | Typical ROI (Sri Lanka) |
|---|---|---|---|---|---|
| Pallet Shuttle System (ASRS/Semi-Auto) | Very High (80% - 88%) | Lane Dependent (FIFO / LIFO) | High (0.8 - 1.2 m/s Autonomous) | Extremely Low (Forklift outside lanes) | 14 – 22 Months |
| Conventional Selective Rack | Low (38% - 45%) | 100% Immediate Access | Moderate (Forklift travel heavy) | Moderate (Exposed front uprights) | Immediate (Low Capex) |
| Drive-In / Drive-Through Rack | High (65% - 72%) | Low (LIFO strict) | Slow (Cautious vehicle creeping) | Severe (Trucks enter deep frame) | 24 – 36 Months |
| Push-Back Rack (Gravity Cart) | Moderate-High (55% - 65%) | Lane Dependent (2-6 Deep LIFO) | Moderate | Low-Moderate | 20 – 28 Months |
| Pallet Flow Rack (Gravity Roller) | High (70% - 78%) | Strict FIFO Rotation | High (Passive gravity lanes) | Low | 28 – 40 Months |
With decades of dedicated pallet rack manufacturing experience adhering to global RMI (ANSI MH16.1), FEM, and CE standards, our industrial plants manufacture full-spectrum warehouse systems engineered to endure demanding tropical operations.
Constructed strictly from certified Q235B and high-yield Q355B structural coil steel from Baosteel/Shougang, guaranteeing rated deflection thresholds under full seismic and static load limits.
Multi-stage chemical pre-treatment and automated electrostatic epoxy-polyester powder lines ensure a tough, scratch-resistant barrier formulated to counter Sri Lanka's high marine salt corrosion.
In-house CAD/3D structural engineers verify concrete floor anchor embedment, slab thickness requirements, and structural frame bracing according to international building codes.
Dedicated shipping logistics to the Port of Colombo with high-efficiency sea container loading schematics, rust-inhibiting wrapping, and full project customs documentation support.
Crucial commercial, technical, and regulatory considerations for Sri Lankan warehouse operators, industrial engineers, and procurement directors purchasing China-manufactured pallet shuttle systems.
In Sri Lanka, operations typically switch between 1200x1000mm standard industrial wooden pallets (common in domestic FMCG, beverages, and Ceylon tea bulk transport) and 1200x800mm Euro pallets (common in export apparel and airfreight cargo). Our radio shuttles and guide rails are custom-engineered with multi-sensor detection arrays and adjustable guide-rail flanges to safely transport both perimeter-base and two-way or four-way entry pallet formats without jamming.
Warehouses in coastal industrial zones like Kelaniya, Wattala, and Colombo Port experience persistent relative humidity above 80% with airborne chloride salinity. We apply a multi-step acid-wash phosphate pre-treatment followed by thermoset architectural-grade polyester powder coating baked at 200°C (60-80μm coating thickness). For the shuttle running rails and floor tie plates, we supply pre-galvanized or hot-dip galvanized finishes ensuring rust-free longevity exceeding 15+ years.
Direct ocean freight voyages from Shanghai, Ningbo, or Shenzhen ports to the Port of Colombo average 12 to 18 transit days. We bundle components into dense 40ft High Cube (40HQ) containers with custom dunnage and heavy-duty steel strapped bundling to avoid transit shifting. Our logistics desk provides accurate packing lists, Bill of Lading, Certificate of Origin, and HS code classifications to facilitate seamless clearance under Sri Lanka Customs regulations.
Our shuttle carts are engineered with modular plug-and-play electronics, industry-standard Omron/Siemens microcontrollers, and easily accessible drive assemblies. We provide full English technical manuals, interactive video troubleshooting guides, and a comprehensive spare-parts consignment (spare motors, sensors, wheels, remotes) with every installation. Furthermore, our remote diagnostic team provides live engineering assistance via video links.
Because pallet shuttle racking concentrates extreme vertical loads across smaller surface footprints compared to standard selective racking, the concrete floor slab must typically deliver a compressive strength of at least 25-30 MPa with a minimum thickness of 180-200mm. As part of our pre-engineering service, UNARCO's project engineers calculate baseplate point loads, anchor bolt embedment depths, and floor flatness (FF/FL) specifications to ensure complete structural safety prior to shipment.
