Automating the Finished-Goods Warehouse of a Major Steel Producer
One of India's Largest Integrated Steel Producing Companies

The Challenge
Primary steel producers face a storage problem unlike any other industry. Finished product is heavy — pallet loads of plate, coil pieces, bar bundles, forgings and fabricated assemblies are routinely several tonnes — it is irregular, often with sharp edges or protrusions, and the warehouse must absorb the continuous output of a mill that never stops. Land at integrated steel sites is expensive and usually already spoken for, so expansion by building sideways is rarely an option: capacity has to come from building upwards. Traditional steel warehouses rely on overhead cranes and manual operators working in proximity to multi-tonne loads — producing chronic problems of low storage density, limited picking accuracy, and persistent safety hazards for crane and yard operators.
The Solution
An integrated heavy-duty AS/RS was engineered for dense steel product storage, combining vertical stacker retrieval, case-level miniload and rail-guided transport. A Pallet SRM (Stacker Retrieval Machine) at 30+ m height with 3-tonne unit-load capacity is dedicated to palletised steel products — going vertical unlocks storage capacity without acquiring additional land. A Miniload ASRS handles smaller steel SKUs including forgings, fasteners, machined components, tooling and consumables. RGV (Rail-Guided Vehicle) transport links the SRM aisles, miniload aisles and dispatch lanes — purpose-built for heavy loads, running autonomously 24/7. A pallet conveyor backbone connects the mill, AS/RS inbound, quality and dispatch lines — heavy pallets move without forklifts or manual handling. Integrated WMS/WCS controls every pallet, every retrieval and every dispatch, giving production and logistics teams real-time finished-goods inventory visibility.
Systems Used
- Pallet SRM at 30+ m, 3-tonne capacity
- Miniload ASRS for smaller steel SKUs
- RGV rail-guided vehicle transport
- Pallet conveyor backbone (mill to dispatch)
- Integrated WMS/WCS
Why This Matters for South African Operations
In steel, a warehouse full of finished goods is also a warehouse full of working capital. Every day a coil, plate or bar waits for a manual retrieval is a day of tied-up cash and a day closer to a delivery penalty. This case is a proof point that AS/RS technology can be engineered for steel-industry unit loads: 30 m+ stacker heights, multi-tonne pallet payloads, RGV-based horizontal transport and mixed pallet/miniload storage in one system. The same blueprint is directly transferable to downstream service centres, fabricators and heavy-component producers.
