A few days ago, a client contacted us regarding the storage layout of their new warehouse. They plan to store goods on pallets and use forklifts for handling, but they were unsure whether medium-duty racking or heavy-duty pallet racking would be the better option.
Medium-duty racking, commonly referred to as longspan racking, is typically designed for manual picking operations, with load capacities usually up to around 800 kg per level.
Selecting the right racking system affects not only storage efficiency but also warehouse safety and long-term operating costs. Below is a brief comparison of these two commonly used storage solutions.
1 Overview of Medium Duty Racking
Medium-duty racking is designed for storing goods of moderate weight while maintaining flexibility and ease of manual access. People commonly use it in applications where they do not require pallet handling equipment.
1.1 Load Capacity
Medium-duty racking usually supports loads from about 200 kg to 800 kg per level.
This depends on shelf span, beam type, and material thickness.
This capacity range makes it suitable for storing cartons, small parts, tools, and other manually handled items.
1.2 Structural Features
The columns, beams, and support components of medium-duty racking are generally made from medium-gauge steel. The system balances structural strength with ease of installation.
Most medium-duty racking systems feature a modular design, using boltless or pin-connected components. You can adjust the shelf levels according to storage requirements, allowing the system to adapt to changing inventory sizes.
1.3 Typical Applications
Medium-duty racking is commonly used in:
Small warehouses and order picking areas
Retail stockrooms and back-of-store storage
Light industrial workshops and spare parts storage
Laboratories or facilities storing relatively lightweight materials
1.4 Operation and Maintenance
Medium-duty racking systems are usually operated manually without forklifts or lifting equipment. Maintenance mainly involves periodic checks of beam connections, column alignment, and general structural condition.
2 Overview of Heavy Duty Pallet Storage Racks
Heavy-duty pallet racking is designed for storing palletized goods and heavy loads. It is widely used in industrial warehouses and logistics distribution centers where forklifts are used for material handling.
2.1 Load Capacity
Heavy-duty pallet racking is designed for pallet loads from about 1,000 kg to several thousand kilograms per level. The exact capacity depends on the rack configuration and engineering design.
This makes it suitable for storing bulk goods, industrial components, and large quantities of palletized products.
2.2 Structural Features
Heavy-duty pallet racking systems are manufactured from high-strength structural steel. Upright frames and beams are designed with larger cross-sections to support higher loads.
Additional structural elements such as diagonal bracing and beam connectors ensure overall system stability. In most installations, upright frames are also anchored to the warehouse floor to improve safety.
2.3 Typical Applications
Many warehouses use heavy-duty pallet racking for:
Manufacturing facilities
Large distribution centers
Logistics warehouses
Industrial storage environments handling palletized goods
2.4 Operation and Maintenance
Loading and unloading operations typically require forklifts or other material handling equipment. Recommend regular inspections to check beam connections, upright conditions, anchors, and potential damage from equipment impacts.
