Heavy-duty shelving, also known as beam shelving or pallet racking, typically supports over 500kg per level and can handle up to 5 tons, making it a widely used shelving type in industrial warehousing. Its structure primarily consists of upright frames and beams, assembled from cold-rolled steel, making it suitable for palletized storage and mechanized forklift operations.
Key Parameters
1. Load Capacity: Single-layer load capacity ranges from 500kg to 5 tons, with unit shelving spans generally not exceeding 4 meters and depths within 1.5 meters.
2. Height Adjustment: Layer height can be freely adjusted in multiples of 75mm to accommodate goods of different sizes.
3. Applicable Space: Low-level warehouses typically do not exceed 12 meters in height, while ultra-high-level warehouses (automated storage systems) can reach up to 30 meters.
Structure and Materials
1. Component Composition
Uprights: Made of Ω-shaped steel or cold-rolled special-shaped steel, with diamond-shaped punched holes on the surface to enhance load-bearing capacity. Common specifications include 90x65, 100x67, etc.
Beams: Primarily cold-rolled P-type closed beams, connected to hanging pieces via welded beams and secured to uprights with safety pins to prevent dislodgement due to external impact.
Support Structure: Horizontal braces, diagonal braces, and self-locking bolts ensure overall stability, preventing shelving instability caused by bolt loosening.
2. Materials and Processes
Steel Treatment: Surface treated with acid washing, phosphating, electrostatic spraying, etc., to provide waterproofing and rust resistance, extending service life.
Pallet Alternatives: Typically use pallets or steel decks to facilitate forklift handling and reduce manual operations.
Core Advantages
1. Efficient Storage
Supports random access to goods, allowing forklifts to reach any storage location directly, enabling FIFO management and improving operational efficiency.
Utilizes vertical space to increase warehouse capacity by 20%-30%, especially suitable for high-rise storage systems.
2. Flexibility and Safety
Modular design requires no welding or screw fixation, enabling easy installation and disassembly to adapt to business expansion needs.
Special safety pins and closed-beam structure prevent beam dislodgement, ensuring cargo stability.
3. Cost-Effectiveness
Low cost, simple maintenance, reusable, with significant long-term operational cost advantages.
IV. Application Scenarios

1. Manufacturing: Storage of raw materials and heavy machinery components (e.g., automotive, chemical industries).

2. Logistics and Distribution Centers: Suitable for high-volume turnover of palletized goods, combined with automated forklifts to enhance efficiency.
3. Retail and Pharmaceuticals: Centralized management of inventory to meet seasonal demand fluctuations; pharmaceutical industry combines temperature-controlled systems for drug storage.
4. Food and Cold Chain: Supports bulk food raw materials and frozen product storage, requiring compliance with hygiene standards.
