Warehouse Rack System Solution for Industrial Storage Optimization
Subtitle
SUNLI manufactures a complete range of warehouse rack systems - selective pallet rack, drive-in rack, shuttle rack, mezzanine, cantilever rack, narrow aisle rack, and long span rack - engineered via finite element analysis (FEA) for optimal load capacity, space utilization, and operational safety across diverse storage applications.
Target Keywords
warehouse racking solution, pallet rack system, high density storage rack, warehouse rack manufacturer, shuttle rack system
· Wasted vertical space
Flat storage utilizes only ground-level space, wasting 60–70% of warehouse height.
· Low storage density
Selective-only configurations waste aisle space, limiting pallet positions per square meter.
· SKU management complexity
Mixed product sizes and weights require flexible storage configurations.
· Structural safety concerns
Inferior rack quality risks collapse under load, threatening personnel and inventory safety.
· Operational inefficiency
Poor rack layout leads to long travel distances and slow picking cycles.
SUNLI offers the following rack system types, each selected based on load requirements, SKU characteristics, and throughput needs:
Rack Type | Load Capacity | Key Feature | Best For |
Selective Pallet Rack | 500–4,000 kg/level | 100% direct access to every pallet | High-SKU, low-velocity storage |
Drive-In Rack | 1,000–3,000 kg/level | Forklift drives into lanes for dense storage | Low-SKU, high-quantity homogeneous goods |
Shuttle Rack System | 1,000–1,500 kg/pallet | Shuttle cart handles pallets within lanes | High-density FIFO/LIFO storage |
Narrow Aisle Rack | 500–2,000 kg/level | Reduced aisle width (1.6–2.0 m) with VNA truck | Space-constrained high-throughput warehouses |
Mezzanine / Platform | 300–1,000 kg/m² | Multi-tier platform maximizing vertical space | Small parts, manual picking, e-commerce |
Cantilever Rack | 500–2,000 kg/arm | Open front for long or irregular items | Pipes, lumber, building materials |
Long Span Rack | 200–800 kg/level | Hand-loaded medium-duty shelving | Hand-loaded small-to-medium parts |
· Space Utilization
Pallet storage capacity per square meter is 2-5 times higher than that of conventional floor storage-depending on the racking type-significantly improving land utilization efficiency.
· Load Capacity
Maximum load capacity per level reaches 4,000 kg, with a single upright unit capacity of 6,500 kg (ASRS grade), meeting heavy-duty storage requirements.
· Structural Safety
Designed using Finite Element Analysis (FEA) with a safety factor of ≥1.5; complies with international standards FEM 10.2.08 and AS 4084.
· Surface Durability
Features an epoxy electrostatic powder coating, verified by ISO 9227 salt spray testing to ensure excellent corrosion resistance.
· Customization
Beam heights are flexibly adjustable in 50-75 mm increments to accommodate various cargo specifications.
· Installation Speed
Utilizes a pre-engineered bolted connection structure; installation is over 30% faster than traditional welded structures, shortening the construction timeline.
· Compliance
Products hold CE certification and SGS test validation, strictly adhering to AS 4084 standards to ensure reliable, compliant manufacturing and testing.
· Logistics & Distribution Centers
Multi-client 3PL warehousing with mixed SKU profiles
· Retail & E-commerce
Order fulfillment centers requiring high-pick-density configurations
· Food & Beverage
Cold storage racking with galvanized/epoxy anti-corrosion finishes
· Automotive
Tier-1 supplier parts warehousing with heavy-duty cantilever and selective racks
· Building Materials
Long-item storage using cantilever systems
· Pharmaceutical
GMP-compliant rack with full traceability and cleanroom-compatible finishes

Combined selective pallet rack and long span rack system for JD.com's overseas distribution center. The solution optimized cross-dock and reserve storage operations, supporting high-velocity e-commerce order fulfillment across the Middle East region.
Multiple rack system deployments across beverage and pharmaceutical distribution centers, including shuttle rack systems with 110,000+ pallet positions, designed for FIFO compliance and rapid throughput.
Q: How do I choose between selective pallet rack, drive-in rack, and shuttle rack?
A: Selective rack offers 100% direct access but lower density - ideal for high-SKU operations. Drive-in rack maximizes density for low-SKU homogeneous products. Shuttle rack combines high density with automated lane handling, suitable for medium-to-high throughput operations requiring FIFO/LIFO flexibility.
Q: What pallet size should I provide before quotation?
A: Standard pallet dimensions (e.g., 1,200 × 1,000 mm, 1,200 × 800 mm), pallet height, maximum load weight, and whether pallets are wooden, plastic, or steel. Custom pallet sizes can be accommodated with adjusted beam lengths and load ratings.
Q: Can rack height and load capacity be customized?
A: Yes. SUNLI engineers rack systems via finite element analysis (FEA) to optimize column profiles, beam sections, and bracing configurations for specific height and load requirements, with rack heights up to 34 meters for ASRS applications.
Q: What standards do SUNLI racks comply with?
A: SUNLI racks are tested by SGS and comply with CE and AS 4084 detection standards. Manufacturing follows ISO 9001 quality management, with structural design verified per FEM 10.2.08 guidelines.
