Explore our high-performance structural systems designed to optimize vertical warehouse capacity and commercial product presentation.
In modern industrial logistics and high-volume commercial storage, space utilization is no longer simply about shelves; it is a calculated discipline combining structural metallurgy, seismic resistance, and ergonomic layout design. Longspan storage systems represent the ideal structural compromise between light-duty shelving and heavy-duty industrial pallet racking. They are engineered to store bulky, heavy, yet manual-loaded items without the capital-intensive requirement for dedicated forklifts or specialized material handling equipment.
A true longspan racking configuration consists of three critical structural parts: cold-rolled steel upright frames, horizontal/diagonal truss bracing, and load beams fitted with step profiles that support various shelf decks (such as wire mesh decking, particle board, or galvanized steel panels). Because these systems must bridge horizontal gaps up to 3,000 mm, they require meticulous engineering calculations to prevent deflection. According to FEM 10.2.02 and RMI standards, the allowable beam deflection under full static load must not exceed L/200 (where L is the span length). Managing this threshold ensures long-term safety and structural integrity in automated or high-traffic warehouses.
Founded in 2014, Dongguan Durack Logistics Equipment Co., Ltd. is a premier Chinese storage racking system manufacturer operating a 35,000 m² facility. Backed by 12 years of industry experience and 8 years of global export history, the company generates $28 million in annual export revenue. Our operations are supported by a strict quality assurance system using full-spectrum ultrasonic testing and load-bearing stress evaluations, overseen by 45 dedicated QC specialists. Building on a strong international trading background, our core markets span North America, Europe, and Southeast Asia. We maintain a reliable supply chain network of over 850 partners, catering primarily to third-party logistics (3PL) providers, automated warehouses, and large industrial distributors. Driven by an active R&d division with 65 specialized engineers, Durack offers full OEM/ODM customization options—including bespoke beam profiles, structural steel grades, and dynamic layout designs—launching over 120 new storage products last year.
Every stage of production in our 35,000 m² facility is certified to international standards. From cold-rolling structural steel to ultrasonic weld testing, we guarantee structural integrity.
Purchasing longspan storage solutions directly from a Chinese manufacturer offers significant structural and supply chain advantages. Chinese industrial hubs utilize local metal processing ecosystems that provide unmatched raw material quality control. At Durack, we construct our racking frames using high-yield Q235B steel, a grade preferred in heavy civil engineering due to its excellent weldability, mechanical ductility, and toughness at low temperatures.
Our raw material undergoes a chemical pre-treatment known as Parkerising (phosphating) and multi-stage pickling. This process removes all surface iron oxides, mill scale, and sub-surface impurities. By forming a corrosion-resistant phosphate layer on the clean steel substrate, we ensure maximum adhesion of the electrostatic powder coat. This prevents the sub-film corrosion common in low-tier, untreated steel products, extending the lifespan of our racks in damp, high-humidity coastal warehouses.
Our advanced 600-ton hydraulic presses cold-roll structural steel members, maintaining a dimensional tolerance of ±0.1mm to ensure uniform stress distribution.
Our 7-stage acid-washing bath eliminates impurities, preparing the metal for a flawless 60 to 80-micron powder coating layer that prevents rust.
We test every structural design against global standards, including RMI (North America), FEM 10.2.02 (Europe), and AS4084-2012 (Australia).
Global logistics networks require international compliance and seamless local execution. Procurement managers must verify that the racking supplier understands local seismic zones and building codes. For instance, in seismic zones like Southern California or Japan, structural calculations must account for dynamic horizontal acceleration. Our engineering department uses Finite Element Analysis (FEA) to simulate seismic forces on our rack structures, optimizing upright thickness and baseplate size for safety.
With an extensive network of 850+ global partners, Durack supports international projects from design to final safety certification. Whether adapting to EN 15620 guidelines in Europe or AS4084 specifications in Australia, our team provides custom technical documentation. This localized support accelerates building permit approvals and ensures compliance with local occupational safety regulations.
Enterprise procurement departments prioritize three key metrics: manufacturing scalability, lead-time consistency, and load-bearing safety margins. Dongguan Durack addresses these challenges with automated fabrication systems and a robust supply chain that delivers over 120 new products annually.
Our Quality Control team features 45 specialists who conduct non-destructive testing on structural weld seams. We use full-spectrum ultrasonic diagnostic tools to detect internal porosity and cracks, guaranteeing structural integrity. We also run physical stress-testing on key components to verify that structural load limits meet or exceed our specified ratings, providing consistent quality across all shipments.
The industrial storage industry is shifting toward automated warehouse integration and sustainable manufacturing. As e-commerce fulfillment centers adopt Autonomous Mobile Robots (AMRs) and AS/RS systems, longspan storage systems must incorporate tighter tolerances, integrated RFID tags, and sensor channels.
Durack is also committed to reducing our environmental impact. Our modern coating lines utilize lead-free, non-VOC, thermosetting epoxy powder. This green coating process protects the environment and meets RoHS requirements, helping our global clients achieve their sustainability goals.
