Global industrial facilities face an unprecedented convergence of commercial challenges: skyrocketing land acquisition and leasing costs, critical labor shortages, and demanding consumer SLAs requiring rapid order fulfillment. To remain competitive, leading logistics networks are moving away from manual storage options. The solution lies in advanced Automated Storage and Retrieval Systems (AS/RS).
As a premier global supplier of automated warehouse technology, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. (established in 2015) has spent over a decade designing and implementing heavy-duty AS/RS frameworks. These setups turn standard warehouse volumes into highly dynamic, footprint-optimized assets.
Whether deploying unit-load stacker cranes or intelligent shuttle networks, selecting a highly capable OEM manufacturer is essential. Racking frames for automated storage must be manufactured to much tighter tolerances than traditional selective racking. Even a 2mm deflection can disrupt high-speed automated shuttles.
At Sunli Rack, we understand that no two supply chains require the exact same structural footprint. Our engineering division, staffed by 28 skilled R&D engineers, designs and tests systems specifically for your facility. We release more than 120 new structural improvements and products annually to meet changing market needs.
Our OEM and ODM capabilities include:
Our engineering team utilizes Finite Element Analysis (FEA) software to simulate stress, buckling, and seismic responses. This ensures that every upright frame and support beam is optimized for maximum structural efficiency and long-term durability.
Operating a modern 38,000 m² factory, Sunli integrates automated robotic production lines with rigorous QC processes.

High-performance AS/RS engineering relies on absolute dimensional consistency. Slight misalignments in upright structures or tracking beams can cause automation halts, shuttle stalling, or uneven wear on robotic systems. Our quality control team manages this risks by verifying physical tolerances and load capacities at every stage of production.

By utilizing high-precision tools such as coating thickness testers and digital bolt drawing instruments, Sunli maintains complete traceability. We confirm steel grade compliance, weld penetration, and powder-coating adhesion. This ensures our racking structures perform reliably under maximum payload capacities over long service lifetimes.
Modern distribution hubs operate within global networks that demand strict regulatory compliance. Sunli's engineering team designs and manufactures systems in accordance with standard safety regulations, including:
Designed and manufactured to comply with the Rack Manufacturers Institute specifications, ensuring standard safety margins across North American operations.
Conforms to European standards for static steel racking design, ensuring structural stability for palletized cargo handling.
Structural layouts specifically optimized to comply with Oceanic steel safety, load testing, and deflection limits.
These structural standards are critical for third-party logistics (3PL) providers and fast-turnover e-commerce fulfillment hubs. Sunli integrates high-capacity racking structures with 4-way shuttle systems and autonomous mobile robots (AMRs). This setup enables high-density vertical storage, increasing pallet positions by 200% to 300% compared to traditional selective racking systems.
The future of intralogistics goes beyond static steel racking; it centers on complete operational visibility. Our engineering team works with software integrators to connect hardware systems with modern Warehouse Management Systems (WMS) and Warehouse Control Systems (WCS).
Our technology development focuses on three primary fields:
