Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global designer, manufacturer, and exporter of high-grade industrial racking and automated warehouse storage architectures. Leveraging deep engineering expertise, we provide high-performance physical structures engineered to withstand rigorous industrial environments.
Our production ecosystem operates under strict Quality 4.0 protocols, converting high-grade cold-rolled steel (Q235B & Q355B) into precision-profiled warehouse structures. Guided by a network of over 800 supply chain partners, we ensure uninterrupted raw material sourcing and scale-ready manufacturing capacity.
We utilize computer-controlled roll-forming mills to generate consistent, load-optimized upright profiles. Multiple rolling lines cater to heavy-duty, medium-duty, and light-duty specifications, ensuring minimal material fatigue and structural consistency across production lots.
Robotized welding stations execute high-strength seam welding for beam connectors and baseplates. This automated thermal bonding eliminates human inconsistency, securing superior load distribution and resistance to seismic shear forces.
An advanced, multi-stage pre-treatment wash prepares the steel for a thermosetting epoxy-polyester powder finish. Cured under controlled high temperatures, this surface offers long-term resistance to mechanical wear, impacts, and oxidation.























Our QA laboratory executes physical stress analyses and surface evaluations on every production run. Adhering to International Standard compliance models, we track physical performance parameters to maintain consistent structural ratings.












Industrial storage optimization requires custom configuration based on inventory profile, throughput speed, and access methodology. We design targeted warehouse systems for distinct supply chain sectors.
For operations with shifting SKU mix, we deploy highly adjustable, multi-level selective racking systems. These designs integrate variable-width bays and pick-to-belt levels, maintaining maximum adaptability for diverse tenant needs.
Utilizing robust steel construction and selective layouts, we optimize flow channels for direct carton access. Adjustable long-span shelving segments enable quick, dynamic floor plan updates to keep pace with seasonal demand spikes.
Operating in cold environments requires structural steel engineered for low temperatures. Our cold-storage racks utilize specialty steel chemistry combined with high-density layouts, such as double-deep or drive-in configurations, to minimize thermal loss.
Modern industrial warehousing is evolving toward automation. Sunli structural components are engineered to transition seamlessly from conventional fork-lift access to semi-automated and fully automated operations.
Automated Storage and Retrieval Systems require minimal deflection tolerances under dynamic loads. Our engineering team designs uprights with high torsional rigidity, allowing stacker cranes and vertical shuttles to operate without mechanical interference.
By incorporating precision-aligned guide rails, our racking structures accommodate deep-lane pallet shuttles. This design minimizes operational collision risks and supports high-density, high-throughput logistics.
Prior to production, our R&D team uses advanced FEA software to model load distributions, stress points, and seismic performance. This step validates structural capacity and guarantees reliability under regional design limits.
Navigating international structural requirements is critical for cross-border logistics projects. Sunli manufactures products compliant with key regional design and safety standards.
Designed to meet standard US structural requirements, including specific calculations for seismic load zones and impact resistance.
Compliant with European steel racking design codes, securing structural stability and safety factors across the EU.
Engineered to conform with Australian safety parameters, covering steel storage racking tolerances and installation guidelines.
Conforms with the UK Storage Equipment Manufacturers Association guidelines, emphasizing operational safety and routine inspection criteria.
