Engineered for heavy load limits, modular configurations, and optimized global logistics footprint.
In modern supply chain management and automated logistics networks, the mechanical stability of high-capacity portable shelving is not just a productivity factor—it is a critical safety parameter. As a leading CE Certified Portable Shelving Manufacturer, Dongguan Durack Logistics Equipment Co., Ltd. builds structural systems that strictly align with European standards, including EN 15512:2020 (adjustable pallet racking design principles), EN 15620 (tolerances, deformations, and clearances), and EN 15635 (application and maintenance of storage equipment).
Our certifications provide third-party verification that our portable racking, mezzanine structures, and heavy-duty cantilever systems are structurally capable of withstanding the dynamic loads generated by heavy machinery, lift trucks, and fast-paced warehousing operations. Undergoing rigorous load tests, finite element analysis (FEA), and mechanical evaluations, our products guarantee seismic compliance and long-term durability in high-density facilities globally.
Our heavy-duty frames are engineered from structural carbon steels, primarily Q235B and Q355B (equivalent to S235JR and S355JR according to EN 10025-2). This high-tensile hot-rolled steel profile provides superior yield strength (up to 355 MPa) and ductility, ensuring our systems withstand dynamic impact loads and temperature fluctuations—specifically within sub-zero cold chain environments.
Operating a modern 35,000 m² manufacturing plant in Dongguan, China, our manufacturing line integrates advanced steel rolling, automated stamping, multi-angle bending, CNC punching, robotic welding, and automated surface treatment. By managing the entire production cycle in-house, we secure complete traceability of components and maintain optimal mechanical tolerances across all production runs.
Every piece of portable shelving and heavy-duty structural racking is fabricated using precision industrial processes, documented below:
The manufacturing process starts with sourcing certified steel coils. Our Rolling Mills and Fully Automatic Punching Machines shape structural profiles with precise pitch spacing. Pre-welded structural components undergo full-penetration welding on Automatic Welding Machines to ensure consistent structural strength. Before surface treatment, parts undergo an intensive multi-stage Acid-washing and Parkerising pre-treatment to clear all traces of rust and organic oils, establishing a zinc-phosphate layer that prevents corrosion. Finally, the parts enter the Plastic Powder Coating Line, where a uniform, impact-resistant epoxy-polyester coat is electrostatic-applied and heat-cured.
Quality assurance is integrated into every phase of production. Our team of 45 dedicated QC specialists executes multi-point checks, inspecting raw coil thickness, weld microstructures, and final powder coat performance.
Verifying raw sheet thickness, punching pitch, and profile outer dimensions to maintain exact interlocking fits.
Using electronic magnetic induction gauges to confirm uniform powder-coating dry film thickness between 60 to 90 microns.
Our testing includes:
• Ultrasonic weld inspection
• Load-bearing stress evaluations
• Cross-cut adhesion tests for coating
• 500-hour salt spray corrosion testing
• Heavy dynamic drop and impact testing
Our engineering department is staffed by 65 structural and mechanical engineers. Last year alone, we introduced over 120 new storage designs, adapting to the shifts in third-party logistics (3PL) fulfillment models and e-commerce supply chains. We offer full OEM and ODM options, including customized upright configurations, custom structural steel grades, specialized boltless beam connections, and zinc-plated finishes for demanding environments.
Based in China’s industrial manufacturing hub, Durack maintains a reliable supply chain network of over 850 partner suppliers. This ecosystem enables us to source raw steel, precision hardware components, and specialty plastics reliably, allowing us to manage large orders with consistent lead times even during global shipping disruptions.
The material handling industry is moving rapidly toward automation, and portable shelving systems are adapting to support this transition:
Storage requirements vary significantly by region and industry. We customize our systems to align with specific local demands:
Select components and specialized display systems designed to maximize vertical space utilization.
Essential technical and commercial information for supply chain managers and procurement officers.
Our CE certification verifies compliance with the mechanical structural safety guidelines of EN 15512 and EN 15620. We utilize certified Q235B and Q355B structural steel, and submit all racking assemblies to dynamic finite element analysis (FEA) and physical destructive testing to confirm calculated load ratings.
Standard production lead times typically range from 20 to 35 days from technical drawing confirmation and deposit receipt. This timeline accommodates custom configurations such as non-standard upright heights, specific beam profiles, custom colors, and specialized galvanization requirements.
Acid-washing removes all oxides, scale, and surface contaminants. Parkerising (phosphate conversion coating) creates a crystalline layer of metal phosphates on the steel surface. This layer prevents corrosion from spreading underneath the powder coating and significantly improves final powder adhesion.
Yes. We design and manufacture high-tolerance racking compatible with Automated Guided Vehicles (AGVs), Autonomous Mobile Robots (AMRs), and four-way shuttle systems. We engineer the bottom frame layout, guide rails, and structural tolerances to meet the precise requirements of automated picking and storage systems.
