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 and precision are at the core of our operations. 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.
Outdoor industrial environments pose some of the most aggressive challenges to structural integrity. As global logistics networks expand and urban space constraints intensify, open-air storage systems have transitioned from temporary solutions to critical structural assets. Modern outdoor shelving must resist UV degradation, extreme temperature shifts, wind loads, and chemical corrosion (such as salt mist in coastal zones).
The adoption of hot-dip galvanizing (HDG) conforming to BS EN ISO 1461 and duplex organic powder coatings ensures structural life spans exceeding 20 years in C4 (industrial) and C5 (coastal) environments.
Advanced FEA (Finite Element Analysis) structural engineering models are now standard, ensuring racks can withstand localized seismic activities, extreme wind shear (up to 150 km/h), and uneven ground settlement.
Semi-automated and automated systems, such as Radio Shuttle and Automated Storage and Retrieval Systems (AS/RS), are increasingly being adapted for outdoor structures using IP-rated protective covers.
Industrial sourcing of outdoor racking systems requires strict attention to material chemistry and structural testing protocols. Below is a comparative overview of key material and design standards required by global logistics managers.
| Evaluation Parameter | High-Load Industrial Shelving | Light & Medium Duty Shelving | Supermarket & Commercial Shelves |
|---|---|---|---|
| Typical Load Capacity | 1,000 kg – 5,000 kg per level | 200 kg – 800 kg per level | 50 kg – 150 kg per level |
| Steel Grade | Q355B, Q420 or Grade 50 (ASTM) | Q235B or cold-rolled mild steel | Cold-rolled SPCC / SPCD steel |
| Corrosion Protection | Hot-Dip Galvanizing (80µm+ thickness) | Electrostatic Powder Coating (60-80µm) | Double-sided electrostatic powder coating |
| Safety Compliance | FEM 10.2.02, ANSI MH16.1, AS4084 | EN 15512, ISO 9001 | CE, ISO 14001 |
| Structural Design | Upright framing, heavy box beams, floor anchors | Boltless, teardrop, or slotted-angle style | Gondola configuration, modular uprights |
These ten industry leaders have been selected based on their structural design capabilities, compliance certificates, corrosion resistance technology, and production scale.
Operating from a state-of-the-art 38,000 m² facility, Shenzhen Sanyang excels in heavy-duty industrial pallet racking and automated outdoor systems. Using advanced structural modeling and automated cold-rolling lines, they produce structures designed for harsh environments. Their systems feature robust galvanization processes and thick electrostatic coatings to resist marine and industrial environments.
One of the world's largest manufacturers of industrial racking systems, Stow Group provides premium structural systems. Their outdoor storage racking solutions are engineered with advanced hot-dip galvanized profiles and specific wind-load calculations to ensure stable operation in northern European ports.
