Explore our premium grade heavy-duty, semi-automated, and robotic storage systems engineered for maximum space optimization.
Founded in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has established itself as an engineering powerhouse and premier manufacturer in the heavy-duty industrial racking and automated warehouse storage sector. Anchored by a state-of-the-art manufacturing campus spanning 38,000 square meters, we successfully merge structural engineering expertise with modern logistics automation.
With over 12 years of industry experience and 8 years of intensive global trade execution, Sunli has delivered reliable, high-density storage infrastructures to partners in North America, Western Europe, Southeast Asia, and the Middle East. Through these relationships, we achieve an annual export volume ranging from $18 million to $25 million.
We drive supply chain scalability for third-party logistics (3PL) providers, global e-commerce fulfillment hubs, large-scale industrial distributors, and retail enterprises by developing highly integrated automated shuttle storage systems, heavy-duty racking, and automated guided vehicles (AGVs).
Analyzing key drivers reshaping commercial warehousing, storage footprint density, and logistical cost matrices.
Modern global industrial facilities face unprecedented headwinds. Urban land-use constraints have driven the cost of warehouse floor space to historic heights. Simultaneously, the rise of multi-channel distribution networks requires facilities to process order cycles in hours rather than days. These economic forces have rendered traditional manual static racking obsolete for high-throughput environments. Today's logistics operators are targeting two critical indicators: Volumetric Storage Efficiency (VSE) and Throughput Cycles Per Hour (TCPH).
Automated shelving and racking systems—particularly unit-load Automated Storage and Retrieval Systems (AS/RS), automated pallet shuttles, and Laser-Guided AGVs—bridge the gap between footprint limitation and high-frequency demand. By reclaiming overhead vertical space (often up to 30-40 meters) and removing wide forklift aisles required for static operations, Sunli’s automated systems achieve footprint volumetric utilization rates up to 85% higher than standard selective racking layouts.
Beyond simple density, automated systems drastically lower operational risks. Forklift collisions represent one of the leading causes of pallet rack collapses globally, incurring structural damage and inventory loss. By automating pallet transport using radio shuttles and laser-guided forklifts, operators keep manual machinery away from physical structures. This eliminates collision risks, guarantees constant pallet velocity, and ensures safe inventory flows.
Shenzhen Sunli's production capabilities rely on an established, resilient ecosystem of raw material suppliers and advanced processing partners. Drawing from a network of over 800 supply chain partners, we secure high-grade steel, electrical components, and industrial control systems even during periods of global market volatility.
Our manufacturing facility runs highly optimized automated lines. Raw steel coils (primarily premium Q235B and Q355B structural grades) pass through heavy-duty upright rolling lines, high-accuracy punchers, and automated multi-crossing beam profiling units. Precision robotic welding heads apply continuous structural seams, which are then treated with a multi-stage chemical wash before entering the electrostatic powder spray coating lines.
This vertical integration means we manage production steps, metal tolerances, and coating thickness closely. The result is a highly reliable product, reduced manufacturing waste, and lower production costs. We pass these savings directly to our global commercial clients in the form of cost-competitive high-performance storage systems.

The transition from static steel fabrication to smart logistics hardware with IoT and AI integration.
The automated shelving market is moving from simple mechanical design to integrated hardware-software systems. To support this transition, Shenzhen Sunli is building dynamic IoT features directly into our heavy-duty structures. Our current R&D efforts focus on integrating continuous health monitoring sensors within high-density racking. These strain-gauge arrays and tilt sensors connect with the warehouse Warehouse Control System (WCS) to detect uneven load distributions, structural shifts, or potential overloads before structural damage occurs.
In parallel, we are developing close coordination protocols between static shuttle racks and mobile automated systems (AGV/AMR fleets). In typical warehouses, the rack and the AGV operate as separate systems. Sunli is integrating these layers. Real-time alignment sensors at the shuttle docking stations allow AGVs and shuttles to exchange pallets smoothly. This lowers transition times by up to 18% and eliminates manual interventions.
Finally, we are optimizing our automated cold storage solutions (down to -40°C). Normal steel becomes brittle in extreme cold, posing structural risks. Sunli uses low-temperature, high-toughness steel alloys combined with customized hydraulic components and anti-freezing sensors to ensure reliable continuous operation in cold chain environments.
Custom engineering for regional requirements, environmental conditions, and international structural standards.
Heavy-duty warehouse racking must be engineered for localized site conditions. Industrial installations in North America, Western Europe, and Japan must follow strict local structural rules. Sunli customizes every project configuration using Finite Element Analysis (FEA). This guarantees that our racking systems comply with regional seismic requirements, soil conditions, and municipal safety codes.
For example, in high-seismic zones along the US West Coast or South America, we design with thicker baseplates, high-ductile steel formulations, and heavy-duty cross-bracing patterns. This ensures compliance with regional standards such as the Rack Manufacturers Institute (RMI) guidelines and local building codes. In the European Union, our systems are certified under FEM 10.2.02 (the standard for steel static storage systems design), ensuring safe load limits and minimal vertical deflection.
We also provide localized setup support. In addition to supplying structural materials, we work with certified regional installation teams to handle assembly, alignment, sensor testing, and WMS software integration. This hands-on process reduces project lead times and ensures the automated warehouse meets safety compliance standards from day one.
Our commitment to rigorous international engineering standards and quality control protocols.
