Established in 2015, Shenzhen Sanyang Storage Equipment Manufacturing Co., Ltd. is a leading manufacturer specializing in heavy-duty industrial pallet racking, warehouse shelving systems, and automated material handling solutions. Located in Shenzhen, our modern facility spans a total building area of 38,000 m², equipped with advanced automated roll-forming machines, laser cutters, and robot welding lines.
With over 12 years of industry experience and 8 years of active export experience, Sanyang has expanded its international footprint, achieving an annual export revenue of $28 million USD. Our main overseas markets cover North America, Western Europe, Southeast Asia, and the Middle East, primarily serving global logistics hubs, e-commerce fulfillment centers, third-party logistics (3PL) providers, and large manufacturing enterprises.
Quality Assurance Statement: Supported by 35 full-time QC inspectors, we implement rigorous quality assurance protocols using ultrasonic weld flaw detection, coating thickness testing, and heavy-load stress tests to ensure strict compliance with ISO9001 and international FEM/ANSI safety standards. Backed by a strong OEM/ODM background and a robust network of 1,200 supply chain partners, we offer highly customizable options—ranging from custom dimensions and load capacities to specialized powder coatings and seismic-resistant structural designs.
Innovation drives our continuous growth. Our team of 18 R&D engineers focuses on developing high-density and automated storage systems, successfully launching 65 new products last year alone. Sanyang remains dedicated to providing safe, space-saving, and cost-effective storage solutions for our global clientele.

Cold chain logistics operations present unique challenges that go far beyond standard dry warehouse storage. The primary physical challenge in sub-zero environments is the embrittlement of carbon steel under persistent low temperatures. Standard grades of structural steel become susceptible to brittle fractures, particularly at load concentrations and welded interfaces. To mitigate this risk, Sanyang utilizes specialized low-temperature carbon steel alloys, such as Q355D and Q355E, which undergo strict impact testing at -20°C and -40°C respectively to ensure robust yield strength and ductility.
Elimination of brittle fracture risks by sourcing certified Q355D/E structural steel. Materials are selected for superior impact energy absorption at sub-zero thresholds.
Engineering configurations that allow for the coefficient of thermal contraction. Expansions joints and slotted frame connections prevent structural warping.
Dual-treatment surface finishing combining hot-dip galvanization and low-bake epoxy powder coatings to counteract condensation cycles.
The cold storage sector is transitioning rapidly from static racking to semi-automated and fully automated configurations. Operating a cold storage facility is highly energy-intensive; therefore, maximizing volume density is direct leverage to reducing operational cost. Our technical roadmap focuses on the convergence of heavy-duty structural engineering and robotics.
Over the next decade, High-Density Shuttle Racking Systems and AS/RS (Automated Storage and Retrieval Systems) will dominate new installations. Sanyang is leading this transition by integrating customized guide rails, rack sensors, and automated crane structures designed to run smoothly at temperatures as low as -35°C without lubrication freezing or battery deterioration. Our R&D focuses heavily on dynamic load simulation using FEA (Finite Element Analysis) to ensure that fast-moving shuttles do not cause long-term structural fatigue in cold-rolled frames.
Key Technological Focus: Integrated IoT structural health monitoring. By embedding strain gauges and acceleration sensors directly onto critical frame uprights, Sanyang is pioneering systems that warn warehouse managers of overloading or seismic disturbances before structural failures occur.
Our 38,000 m² Shenzhen factory utilizes automated workflows. Take a look at our complete, quality-controlled production sequence.
Procuring industrial-grade steel racking systems for overseas distribution centers demands absolute compliance with local design, structural safety, and environmental codes. Our engineering team conducts advanced Finite Element Analysis (FEA) to simulate wind, snow, and seismic forces based on specific regional inputs. We cater directly to the compliance needs of the following global regions:
Additionally, we accommodate specific customizable constraints including deep pallet storage configurations (Double Deep), drive-in lane layouts, pallet-flow gravity configurations, and specialized racking options designed for heavy-duty industrial cables and coils.
To reduce risk for global buyers, Sanyang has developed an end-to-end global project management framework. We don’t just ship metal profiles; we deliver certified operational safety.
On-Site Supervision & Local Installation: Our engineering team coordinates directly with certified local contractors across the US, UK, EU, and SEA to ensure all assemblies adhere to native occupational health and safety guidelines. We provide detailed installation manuals, AutoCAD schematics, and video walkthroughs.
Warranty & Lifecycle Inspection: Every rack component manufactured by Sanyang comes with a minimum 5-year structural warranty. We provide spare structural components (upright columns, safety clips, baseplates) inside every container to account for unexpected forklift damage. In case of emergency engineering inspections, our technical support is available 24/7 to furnish material certificates, load tables, and FEA profiles.
Clear answers to critical technical questions regarding cold-storage and heavy industrial racking design.
We primarily use certified Q355D and Q355E low-temperature carbon steel. Standard steel (such as Q235B or Q355B) can become brittle at sub-zero temperatures (-20°C to -60°C), making it prone to sudden cracking under dynamic stress. Our steel includes impact testing guarantees at -20°C (for Q355D) and -40°C (for Q355E) to maintain ductile properties.
We apply a specialized electrostatic powder coating with a low-bake epoxy-polyester formula, cured in high-temperature ovens for optimal adhesion. Alternatively, we offer Hot-Dip Galvanizing (HDG) where components are submerged in molten zinc, providing a self-healing protective layer that prevents moisture penetration during condensation cycles.
Yes. All seismic-zone systems are custom-engineered using Finite Element Analysis (FEA) software. We calculate structural responses based on regional seismic coefficients, then adjust column widths, profile gauges, baseplate dimensions, and anchor bolt specifications to ensure compliance with native building codes (e.g., FEMA and RMI standards).
Our standard production timeline ranges from 20 to 30 days depending on complexity and customization. This timeline includes raw material sourcing, rolling, punching, welding, painting, and comprehensive QC testing. Shipping to North American and European ports generally takes an additional 18 to 30 days.
Yes, we provide fully detailed structural assembly schematics, AutoCAD floor layout drawings, and step-by-step video instructions. Where required by local building departments, we work alongside licensed structural engineers in the destination country to review, approve, and stamp our design calculations.
Engineered for large-scale operations, these warehouse storage products provide high-capacity storage density.
