CE Certified Industrial Shelving Manufacturers & Exporters

Dongguan Hui Lian Intelligent Warehouse Equipment Co., Ltd.

Established in 2016, Dongguan Hui Lian Intelligent Warehouse Equipment Co., Ltd. is a specialized manufacturer focused on the design, production, and supply of industrial storage racks and intelligent warehouse systems. With 15 years of industry experience and 8 years of export history, we build high-capacity racking systems tailored to the needs of modern logistic hubs and industrial distribution centers.

Our manufacturing facility in Dongguan covers 18,500 square meters and features advanced machinery, including automated laser forming machines, high-precision roll forming production lines, and robotic welding stations. Supported by a skilled team of 126 research and development engineers and 56 quality control inspectors, we maintain full control over the production process—from choosing the raw materials to the final powder-coating stage.

We supply clients in over 30 countries across North America, Europe, Southeast Asia, the Middle East, Australia, and South America. By maintaining partnerships with over 850 material suppliers and logistics companies, we ensure reliable production, steady pricing, and consistent delivery times, even during busy market seasons.

CE Technical Compliance & Structural Metallurgy

The structural integrity of industrial warehouse storage shelves depends heavily on the chemistry of the steel and the rolling methods used. We use cold-rolled carbon steel coils, primarily grades Q235B and Q355. These grades are chosen for their balanced yield strength, ductility, and weldability. When forming structural profiles, we monitor uniform roll pressure to prevent micro-fracturing along bend lines. This ensures the steel profiles remain stable under high-stress conditions.

To obtain CE certification, our designs undergo rigorous finite element analysis (FEA) using specialized structural design software. In accordance with EN 15512 guidelines, we test beam-to-upright connections, base plate loads, and overall frames for structural safety. Our testing looks at physical properties like shear capacity, elastic bending behavior, and buckling resistance. This process ensures that our heavy-duty industrial shelving, pallet racking, and mezzanine systems maintain their rated load capacities with a safety factor matching international warehouse safety codes.

Surface treatment is also key to long-term reliability, especially in humid or temperature-controlled warehouse settings. Our automated spray painting lines use an electrostatic powder coating process. The steel receives a multi-stage wash, an iron phosphate conversion coating, and a clean-water rinse before the dry polyester powder is applied. Curing at temperatures between 180°C and 200°C produces a durable, scratch-resistant finish with a thickness of 60 to 80 microns. This coating helps protect the racks from corrosion and mechanical wear in active distribution hubs.

Engineering Future-Ready Warehouse Solutions

Industrial storage is becoming increasingly digital and automated. As logistics centers move toward unmanned operations, the demand for high-precision, automation-ready racking systems continues to grow. We focus our research on integrating static racks with modern automated technologies. This includes developing low-tolerance shuttle racking networks, structural frames for high-rise automated storage systems (AS/RS), and modular layouts that allow warehouses to scale up their storage capacity easily.

We are also researching ways to build safer, more eco-friendly storage systems. This includes analyzing seismic energy absorption to protect installations in earthquake-prone regions, and using lighter, high-strength micro-alloyed steel to reduce structural weight without losing load capacity. Additionally, we are looking into using bio-based powder coatings and low-carbon recycling processes to help global supply chains reduce their environmental impact.
