Precision-engineered systems designed to maximize space utilization and optimize picking pathways
Modern supply chains demand unparalleled throughput speed, storage density, and accuracy. Traditional manual warehousing methodologies struggle to cope with the explosive growth of e-commerce, strict labor compliance regulations, and fluctuating real estate costs. This inflection point has pushed Automated Storage and Retrieval Systems (AS/RS) to the forefront of logistical engineering.
From early single-mast stacker cranes to today’s intelligent multi-shuttle fleets and 3D robotic matrices, AS/RS technology has transitioned from basic mechanical automation into a data-driven science. Dynamic load calculations, real-time kinematics optimization, and seamless integration with complex Warehouse Execution Systems (WES) are now baseline requirements for any high-performance automated facility.
“AS/RS integration reduces floor footprint requirements by up to 85% while simultaneously increasing sorting and retrieval speeds by over 300% when compared to manual operations.”
Founded in 2014, Dongguan Durack Logistics Equipment Co., Ltd. operates a premier 35,000 m² advanced manufacturing facility, delivering robust storage systems globally.
With over 12 years of core industry experience and 8 years of global export history, Dongguan Durack Logistics Equipment Co., Ltd. generates $28 million in annual export revenue, shipping structures to North America, Europe, and Southeast Asia. We support a stable supply chain network of over 850 partners, delivering systems directly to third-party logistics (3PL) providers, automated warehouses, and large industrial distributors. Backed by 65 specialized engineers, our R&D division launched over 120 new storage products last year, establishing Durack as a primary OEM/ODM partner for custom-profile beams, structural steel grades, and dynamic layouts.
Analyzing key pain points and strict operational metrics demanded by international warehouse planners
Global systems integrators require racking designs to strictly align with EN 15512 (European) and RMI MH16.1 (US) standards. Durack utilizes full-spectrum ultrasonic weld testing and certified steel grades to meet strict local safety guidelines.
Automated cranes and shuttles require strict tolerances. High-bay racking profiles must maintain vertical deviations under 1:1000. Durack’s advanced cold-rolling and automated punching machines ensure these tight physical clearances.
Our OEM design teams optimize racking structures to seamlessly clear shuttle control paths, sensor reflector brackets, and fire protection drops, reducing mechanical risks during installation and commissioning.
How Durack translates raw steel into seismic-certified, highly stable structural arrays
Every dynamic AS/RS system we design undergoes simulated Finite Element Analysis (FEA) before tooling begins. Our engineers model seismic forces (based on USGS and Eurocode parameters), dynamic loading from accelerations of shuttle carts (up to 2.0 m/s²), and vertical structural deflection limit calculations. Structural profiles are designed to limit elastic deformation to under L/300, avoiding positioning issues with optical sensors on automated cranes.
Our simulation process accounts for multi-axis wind loads for clad-rack buildings, floor-slab load distributions, and localized buckling behavior of ultra-thin, high-tensile steel cold-formed shapes. This modeling reduces raw material waste while maintaining a safety factor of 1.65+ on dynamic load paths.
We source cold-rolled structural steels from China's leading mills, selecting certified Q235B and Q355B (equivalent to European S235JR and S355JR respectively). Using steel with defined yield points ensures predictable performance under dynamic thermal stresses (e.g. cold storage environments down to -30°C).
Following automatic structural fabrication, components undergo a multi-stage chemical pretreatment, including hot acid-washing and zinc-phosphate parkerizing. This prepares the surface for our electrostatic polyester powder coating line. The resulting finish resists impact and chemical degradation, maintaining a uniform paint thickness of 60–90 microns.
Bespoke configurations tailored to solve storage density challenges across sectors
Designed for fast access, high SKUs, and rapid cycle rates. Durack designs mini-load racks and multi-shuttle arrays that support rapid tote and bin transfers, streamlining quick picking operations.
Operating in environments down to -30°C requires specialized steel grades and connection designs. We design high-density radio shuttle racks and drive-in systems that maximize space utilization in climate-controlled areas.
Our heavy-duty cantilever racking and roll-formed pallet racking carry raw steel, tooling dies, and engine components, keeping heavy industrial inputs organized and accessible.
We supply modular mezzanine systems, supermarket gondola racking, and pegboard display arrays to keep inventory moving between backrooms and front-of-house displays.
How Durack engineering addresses tomorrow's material handling challenges today
Integrating strain gauges and laser distance sensors directly into critical upright columns to monitor rack health. This lets facility managers identify overloaded bays or impact zones before a failure occurs.
Developing low-friction polymer-steel composite rails that reduce noise and wear during crane acceleration. This supports speeds up to 4 m/s while extending wheel life.
Using lightweight high-yield steel alloys (Q460) to reduce dynamic mass in moving shuttle structures, saving energy without compromising structural capacity.
