Engineered for warehouse scale, seismic stability, and optimized logistics workflows.
For over a decade, we have designed, manufactured, and deployed safety-compliant industrial shelving systems that empower global supply chains. Guided by rigorous structural engineering principles, our solutions minimize structural footprint while maximizing volumetric efficiency.
Our dynamic quality team of 35 QC experts enforces step-by-step verification protocol. Every ton of steel is subjected to yield limit evaluations, precision ultrasonic testing of robotic welds, and detailed dry-film thickness measurements of protective powder finishes. We do not compromise on static load ratings or mechanical tolerances.
Our team of 28 skilled R&D engineers translates storage challenges into high-efficiency racking architecture. Introducing over 120 new structural improvements and products annually, Sunli designs robust dynamic flows, automated shuttle integration (AS/RS), custom color-coded multi-tier systems, and tailored frame profiles for large-scale enterprise warehouses.
Take a visual tour inside our ISO 9001-certified factory to see how raw steel is transformed into high-performance industrial shelving.
Shenzhen Sunli Intelligent Logistics leverages the deep capabilities of China's industrial clustering to provide unmatched price performance, technical precision, and lead-time guarantees.
We source raw, certified grade structural steel (typically Q235B and Q355B) directly from leading state mills. This stable raw material supply chain insulates our clients from pricing shocks and material impurities common in smaller operations.
Our automated production facilities feature dedicated rolling lines for light, medium, and heavy-duty profiles. This ensures that dimensional tolerances remain under ±0.5mm, reducing alignment anomalies during onsite installation.
Based in Shenzhen, we sit on one of the world's most robust shipping networks. Our geographic location expedites inland transport and export clearance, meaning lower shipping costs and shorter international lead times for global 3PL networks.
Different regions require specific seismic, steel prep, and dynamic load testing protocols. We design racking systems to meet RMI, FEM, and AS4084 guidelines.
| Racking Class & Type | Primary Material Standard | Surface Treatment | Compliance Approvals | Typical Industrial Use Case |
|---|---|---|---|---|
| Selective Pallet Racking | High-Tensile Cold Rolled Q235B / Q355B | Electrostatic Powder Epoxy-Polyester (80-120μm) | CE, ISO 9001, FEM 10.2.02 compliant | FMCG Storage, Distribution Hubs, General Manufacturing |
| AS/RS High-Bay Racking | Structural Steel Grade ASTM A572 Equivalent | Precision Finished and Heat Cured anti-wear coating | ANSI / RMI MH16.1, EN 15635 | Automated cold storage, High-speed ecommerce fulfillment |
| Drive-In / Drive-Through | Heavy-Duty Steel Profile with reinforced connectors | Powder Coating with Corrosion Protection layer | CE, AS4084 (Australia) | High-Density homogeneous batch inventory, Cold Storage |
| Multi-Tier Mezzanine | Structural H-Beam & Cold Formed Decking | Anti-skid structural plating, fire-retardant coating | SGS Tested, fire safety certified layouts | Automotive Parts distribution, manual sorting zones |
Deploying major warehouse structures internationally requires local permit adherence. We bridge this gap by coordinating structural load calculations and seismic analysis with licensed civil engineers worldwide.
Many suppliers focus only on steel thickness. At Sunli, we focus on material formulation and yield strength. Our structural engineering team matches Q235B and Q355B steel grades to actual ambient temperatures. For sub-zero operations, we specify steel with tested low-temperature impact properties to prevent brittle failures under load.
Our surface finishing line applies an epoxy-polyester hybrid dry film thickness of 80 to 120 micrometers. This protects the underlying steel against relative humidity spikes and mechanical impacts during active forklift operations.
Racking is no longer just static steel. Modern global supply chains demand integration with dynamic, automated material handling machinery.
Modern facilities build straight up. We design automated storage and retrieval system (AS/RS) structures up to 30 meters high. This requires tight vertical tolerances (±2mm overall deviation) so stacker cranes run smoothly.
We adapt our base structural layouts for autonomous mobile robots (AMRs) and laser-guided automated vehicles. This includes wider aisle turning clearances, specific floor-level flatness tolerances, and clear rack-sensor visibility.
Our engineering plans integrate gravity-flow lanes and dynamic shuttle carts (Radio Shuttles). This changes stock management from traditional static placement to high-density first-in, first-out (FIFO) inventory control.
