High-performance warehouse equipment engineered for extreme load capacities and seamless AGV workflow integration.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a preeminent global leader in heavy-duty industrial racking, automated shuttle racking, and integrated warehousing storage solutions. Operating from our highly advanced 38,000 m² manufacturing base, we combine deep engineering know-how with dynamic manufacturing agility. Backed by 12 years of industry experience and 8 years of dedicated international trade execution, we engineered systems that optimize global supply chains across North America, Western Europe, Southeast Asia, and the Middle East.
Quality control forms the bedrock of our company's E-E-A-T credentials. Our operation supports a dedicated team of 35 QC inspectors and 28 structural design engineers. By introducing over 120 product updates and structural patents annually, we guarantee that our structural elements exceed international testing codes (including EN, FEM, and ANSI standards). We specialize in customizable high-density racking configurations, anti-corrosive powder coatings, ESD-protective finishes, and high-efficiency components that streamline warehouse processes for major global 3PL operators, e-commerce giants, and cold-chain facilities.
"Modern intra-logistics requires structural systems that do not merely hold weight, but actively support the high-speed cycle of robotic picking, autonomous transport (AGV/AMR), and micro-fulfillment workflows. Our mission is to bridge heavy engineering with smart logistics automation."
Navigating the transition from passive warehousing to real-time high-density fulfillment centers.
The global warehousing market is currently undergoing a massive structural transformation. Spurred by accelerated omni-channel e-commerce growth, skyrocketing industrial real estate costs, and systemic labor shortages, organizations can no longer afford to treat warehouse space as static storage. High-density racking, drive-in systems, and specialized industrial bins have evolved from standard storage items into highly calibrated logistics assets designed to minimize footprint while maximizing cycle frequency.
Maximizing vertical storage limits the need for expensive warehouse expansion. Our structural steel systems permit safe, heavy-duty stacking exceeding heights of 15 meters, while maintaining compliance with stringent seismic and structural safety regulations.
As automated guided vehicles (AGV), autonomous mobile robots (AMR), and radio shuttle carts become standard components of modern warehouses, storage interfaces must support tight tolerances down to the millimeter to prevent vehicle tracking faults.
Modern distribution centers handle vastly diverse inventory profiles. Racking configurations must feature adjustability, heavy load metrics (up to 4000kg per level), and tailored safety barriers to withstand continuous forklift impact.

How our storage systems solve real-world logistical challenges across specific industries.
In high-velocity e-commerce environments, horizontal travel times slow down picking operations. Our multi-tier cold-rolled steel warehouse shelving systems convert warehouse volume into highly accessible pick modules. Built with optimized heights and anti-corrosive powder finishes, these shelving systems integrate seamlessly with overhead light-directed sorting lines and picking carts. This layout decreases search times and streamlines replenishment sequences in fulfillment centers worldwide.
Electrostatic discharge represents a major risk for microelectronics, semiconductors, and electronic sub-assemblies. Sunli manufactures specialized ESD protective industrial racking utilizing static-dissipative powder coatings and ground-connected structural components. By providing paths to safely discharge static build-ups, these systems ensure sensitive inventories remain protected while stored in high-density configurations.
Operating in sub-zero environments (down to -30°C) subjects structural steel to increased brittleness. Our heavy-duty racking uses certified Q235B and Q355B high-grade steel, cold-formed to precise tolerances, ensuring ductile resilience at sub-zero temperatures. Combined with thick, moisture-resistant protective coatings, these systems prevent structural degradation caused by condensation cycles, safeguarding automated cold storage installations.
Storing engine blocks, transmission assemblies, and heavy stamping dies requires maximum structural load capability. Our heavy-duty industrial racking handles payloads exceeding 4,000 kg per beam level. Equipped with thick, powder-coated column protectors, safety lock pins, and wide-profile base plates, these structures withstand forklift collisions while maintaining load path stability during seismic events.
Fusing steel fabrication with artificial intelligence, dynamic sensor metrics, and autonomous transport.
The warehouse of 2030 will function as a unified cyber-physical organism. At Sunli, our technology roadmap outlines the integration of structural steel fabrication with intelligent software, sensing networks, and high-precision automation systems. Rather than viewing the rack as a simple metal frame, our engineering divisions design structures that actively interact with modern transport technologies.
By investing heavily in automated machinery and robotic welding cells, we maintain high dimensional accuracy across our product range. This consistency ensures that whether you deploy a manually operated shelving setup today or transition to an automated AS/RS environment tomorrow, your structural foundations remain fully compatible with new technologies.
Why sourcing from Shenzhen Sunli maximizes capital allocation and ensures consistent lead times.
Procuring structural warehouse racking from China provides significant supply chain and cost benefits when partnering with an experienced exporter. Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. sits in the heart of China's premier industrial and technology hub, offering distinct logistical advantages:
Direct partnerships with domestic steel mills ensure a reliable supply of raw steel. This proximity insulates us from material shortages, allowing us to maintain stable, competitive pricing even amid global market volatility.
Our 38,000 m² factory operates automated roll-forming and robotic welding lines. This high level of automation reduces labor overheads and improves dimensional precision across large-scale production runs.
Located near major deep-water ports in Shenzhen and Guangzhou, we offer streamlined container loading, customs clearance, and global ocean freight forwarding to reduce overall transit times.
Engineered to meet national building codes, structural standards, and safety certifications worldwide.
Deploying heavy industrial racking systems requires strict adherence to regional safety codes and building regulations. Sunli designs systems to meet or exceed major international structural standards:
We provide comprehensive design support, delivering detailed CAD layouts, load capacity charts, and site installation instructions for every project. This ensures seamless onsite assembly and trouble-free integration with localized building infrastructure.
Answers to common technical, logistics, and customization questions from procurement teams worldwide.
We primarily utilize high-tensile hot-rolled and cold-rolled steel coils, focusing on grades Q235B and Q355B. These steel formulations offer excellent yield strength, ductility, and structural weldability, ensuring reliability under high-load applications.
Our structural design team uses finite element analysis (FEA) software to simulate maximum load capacity under static and dynamic stress patterns. We verify these simulations with actual physical testing using our digital display bolt drawing instruments and laboratory hydraulic presses.
We offer advanced electrostatic powder-coating finishes, checking thickness using coating thickness gauges. For high-humidity, marine, or cold storage conditions, we provide hot-dip galvanized finishes for long-term corrosion protection.
Yes. Our engineering division works with your automation provider to design racking clearances, aisle spaces, guidance paths, and picking bays, ensuring compatibility with sensor tracking and automated material handling equipment.
Typical production lead times range from 20 to 35 days, depending on structural customization and order volume. Our proximity to the ports of Shenzhen and Guangzhou helps reduce local transit times to speed up shipping departures.
