Engineered to maximize vertical warehouse space, load capacities, and logistical workflow efficiencies.
Established in 2014, Nanjing Dulis Warehouse Equipment Co., Ltd. (operating globally under the premier industrial brand DuraRacks) has consolidated its status as a leading engineering and fabrication authority in high-performance warehouse racking. With over 12 years of specialized industry experience and 9 years of direct export capability, we operate a modern industrial campus covering 38,000 square meters.
We solve structural bottlenecks for complex industrial operations. Our core design paradigms revolve around heavy-duty pallet racking, dynamic drive-in racking networks, space-saving cantilever racks, and automated warehouse structures. Our engineering achievements fuel over $32 million USD in annual export revenue, driving supply-chain efficiencies across five continents.
By using premium Q235B and Q355B cold-rolled steel, DuraRacks delivers system integrity that stands up to severe loading profiles, seismic loads, and harsh thermal shifts. We ensure that your capital investment translates directly into safe, scalable, and optimized storage capacity.
Analyzing key structural shifts in industrial supply chains, material demand, and warehouse automation readiness.
Rapid growth in SKU counts and rising industrial real estate costs force logistics managers to target high-density systems. Dynamic stacking racks, double-deep pallet configurations, and push-back channels allow operations to boost capacity by up to 85% compared to traditional single-selective racks.
Industrial installations must meet stringent structural codes like the RMI (Rack Manufacturers Institute) standards in North America and FEM 10.2.02 in Europe. Global operators require Finite Element Analysis (FEA) data confirming frame resilience during seismic events before placing orders.
Long leads on construction steel have made modular, flexible racking systems (like boltless shelves and knock-down structural pallet racking) highly popular. Quick-ship options and ready-to-assemble structures reduce project timelines, allowing distribution hubs to quickly adjust to seasonal peak demand.
Providing specialized racking and shelving architectures to meet the physical requirements of diverse industrial verticals.
High-volume distribution centers require high throughput and flexible layouts. We integrate teardrop pallet racking systems with boltless, multi-tier shelving systems. This hybrid layout speeds up pick cycles for smaller parcels while retaining high-load capabilities for bulk storage pallets.
Sub-zero logistics facilities demand structural configurations that withstand extreme cold. DuraRacks provides hot-dip galvanized racking and specialized low-temperature powder coatings. These prevent steel embrittlement, rusting, and paint cracking at temperatures down to -30°C.
For heavy manufacturing, storing heavy molds, dies, and raw metal coils requires extreme load-carrying limits. We design customized, heavy-duty structural channel racks and roll-out shelf units. These configurations can carry over 4,000 kg per level, allowing for safe, overhead crane-assisted access.
Quality and structural integrity form the bedrock of our manufacturing philosophy. At DuraRacks, our dedicated quality control team consists of 45 certified QA personnel. They implement multi-stage inspections aligned with ISO9001, CE, and European FEM standards.
Every single batch of cold-rolled steel profiles undergoes thorough, documented test procedures prior to packaging and dispatch:
| Test Parameter | Standard Applied | Target Threshold |
|---|---|---|
| Steel Yield Strength | GB/T 1591 (Q355B) | ≥ 355 MPa |
| Powder Adhesion | ISO 2409 | Class 0 (No detachment) |
| Salt Spray Test | ASTM B117 | ≥ 500 Hours (Rust-free) |
| Deflection Limit | FEM 10.2.02 | L/200 of Clear Span |
| Weld Joint Integrity | AWS D1.1/D1.1M | Zero structural cracks |

How our engineering team develops customized storage solutions to address future supply chain demands.
Driven by an experienced team of 68 R&D engineers, DuraRacks delivers advanced structural Finite Element Analysis (FEA) and customized CAD/BIM warehouse layout simulations. We offer full OEM/ODM customization options, tailored seismic load engineering, custom powder-coating finishes, and custom beam profile dimensions.
Last year alone, our engineering team launched 85 new product innovations and patented racking components, helping clients optimize storage density and simplify installation.
Our ongoing technical development focuses on three primary goals: reducing setup times through snap-together connections, lowering raw material usage through high-tensile material profiles, and designing components compatible with Automated Storage and Retrieval Systems (AS/RS).
Ensuring compliance with local building regulations and reliable delivery to global distribution hubs.
We supply regional 3PL hubs, large e-commerce fulfillment operations, cold storage facilities, and heavy industrial assembly plants.
Supported by a robust network of over 1,200 qualified supply chain partners, DuraRacks operates as an integrated direct-export manufacturer. Our facility near major transport links simplifies logistics to major international ports, reducing ocean freight costs for bulk cargo.
We provide full customs handling documentation, load calculations, and structural layouts. We offer comprehensive installation drawings and video guidelines, helping clients set up racking systems efficiently and safely on-site.
By offering customized packaging solutions, we protect powder-coated surfaces and galvanized steel columns from moisture and friction damage during long maritime transits.
