Browse our top-tier CE-certified vertical storage products, engineered for maximum mechanical durability, warehouse security, and optimal product organization.
The commercial and industrial landscape is experiencing a structural shift. With global logistics, modern e-commerce expansion, and specialized cold chain operations driving demand for space, horizontal warehouse expansion has become economically non-viable. Companies are forcing their engineering frameworks to think vertically. Today, Vertical Storage Units (VSUs) and multi-tier mezzanine pallet systems represent the cornerstone of space optimization, throughput speed, and dynamic inventory management.
High-bay racking systems and automated storage/retrieval systems (AS/RS) require strict adherence to international safety metrics. A manufacturing defect or sub-standard structural profile in a vertical rack can lead to catastrophic warehouse collapses, jeopardizing both personnel safety and million-dollar supply chains. Consequently, global procurement teams in North America, Western Europe, and Australia prioritize CE Certification (including compliance with standard DIN EN 15512 and FEM regulations) to guarantee load integrity, high lateral stability, and structural predictability under load.
By utilizing high-grade structural verticality, warehouses can achieve up to 85% footprint conservation compared to traditional ground-storage setups, permitting a denser concentration of SKUs per cubic meter.
Our manufacturing is rooted in certified Q235B and Q355B cold-rolled steel, ensuring that structural loads meet high stress limits and resist seismic and dynamic load forces.
Using electrostatic powder coating and zinc galvanized plating processes, our racking units withstand harsh industrial microclimates and aggressive cold-storage conditions.

We serve a diverse portfolio of client types, primarily catering to 3PL logistics hubs, large-scale e-commerce fulfillment centers, cold storage operations, and heavy industrial manufacturing plants. Supported by a robust network of over 1,200 qualified supply chain partners, DuraRacks operates as an integrated direct-export manufacturer. Our primary overseas markets encompass North America, Western Europe, and Australia.
From certified hot-rolled steel coils to high-finish powder-coated profiles, we maintain full trace-control over our manufacturing process. Explore our technical process flow:
Quality and structural integrity form the bedrock of our manufacturing philosophy. Our dedicated team of 45 certified QA personnel implements rigorous quality control processes aligned with ISO9001, CE, and FEM standards. Every batch undergoes comprehensive product inspection methods, including ultrasonic weld flaw detection, mechanical tensile testing, static and dynamic load capacity testing, and salt spray corrosion resistance evaluation.
By utilizing progressive loading cell simulations and digital CAD stress analysis, our testing protocol certifies that DuraRacks warehouse storage units preserve deflection levels below the strict limit of L/200 under maximal weight load. In addition to structural metrics, our anti-corrosive powder finishes undergo rigorous testing under ASTM standards to resist abrasion and mechanical damage during intense loading maneuvers.
Testing the yield limit of steel base coils ensures columns and uprights do not buckle under structural overload or sudden impacts.
Non-destructive testing (NDT) certifies the structural integrity of weld joints connecting baseplates and beam connectors.
Guarantees that cold-storage facility racking and chemical plant storage surfaces remain free of oxidation for decades.
Industrial buyers face challenges like steel price volatility, freight transit delays, and dynamic safety regulations. Nanjing Dulis (DuraRacks) addresses these challenges through China Factory 4.0 integration. Our automated production line utilizes high-precision CNC laser cutting, robot-guided welding, and automated cold roll forming lines to optimize manufacturing steps, reduce processing waste, and pass cost savings to global procurement managers.

Our vertical storage racks are fully CE-certified and comply with European FEM 10.2.02 and EN 15512 standards for steel static storage systems. We also adhere strictly to ISO9001:2015 quality control processes during manufacturing.
Yes. Our R&D team of 68 engineers utilizes Finite Element Analysis (FEA) software to simulate seismic loads and design heavier base plates, enhanced upright bracing, and high-tensile anchor configurations tailored to local building codes.
We use high-grade Q235B and Q355B structural carbon steel sourced from leading domestic steel mills. These grades provide optimal yield points and tensile strengths, ensuring safety under extreme load conditions.
For cold environments (-30°C) and high-humidity areas, we offer hot-dip galvanized finishes and specialized electrostatic powder coatings. This prevents condensation-induced rust and maintains structural integrity.
Depending on configuration complexity, typical lead times range from 20 to 35 days. This includes CAD/BIM validation, custom tooling setups, roll-forming, coating, packaging, and QA inspection.
