Explore our primary line of high-capacity supermarket shelving, heavy-duty logistics mezzanine structures, and customizable merchandising configurations designed to optimize space utilization.
Established in 2014, Nanjing Dulis Warehouse Equipment Co., Ltd. (operating globally under the brand DuraRacks) has emerged as a premier industrial rack manufacturer and global display fixtures exporter. Headquartered in the manufacturing corridor of Nanjing, China, our company represents a decade-long legacy of advanced structural metallurgy, customized space layouts, and global regulatory compliance.
Boasting over 12 years of core industry experience and 9 years of direct export experience, our state-of-the-art facility spans a modern industrial building area of 38,000 square meters. We specialize in engineering high-capacity pallet racking, automated drive-in storage systems, and premium retail displays, generating an annual export revenue exceeding $32 million USD. We act as a trusted global supply chain link, engineering products to perform in demanding high-throughput distribution hubs and high-footfall commercial spaces.
DuraRacks operates with integrated production pipelines utilizing automatic cold-rolling forming lines, heavy-duty robotic welding cells, and automated electrostatic powder coating technologies. Our facility processes over thousands of tons of high-grade steel annually under rigorous domestic and global safety compliances.
How localization, structural design, and raw material integration at our Nanjing facility translate to capital efficiency and structural safety for global buyers.
Our proximity to mainland China's premier metallurgical centers allows us to source certified Q235B and Q355B structural steel directly. This ensures optimal yield strength, tensile durability, and structural predictability under peak static load conditions.
Equipped with robotic CO2 gas-shielded welding lines and CNC multi-station cold rolling equipment, we achieve ultra-precise profiles with dimensional tolerances within 0.1mm. High precision translates to ease of on-site assembly and structural stability.
Unlike small-scale localized suppliers, DuraRacks components are fully designed and calculated according to European FEM 10.2.02 storage standards and US RMI specification frameworks, backed by static load deflection and seismic load analyses.
From structural raw material processing to final electrostatic powder coating and packaging, our workflows are audited under strict ISO9001 Quality Management standards.
The commercial landscape is undergoing a structural convergence between retail display environments and industrial fulfillment systems. Omnichannel logistics requires retail storefronts to double as micro-fulfillment centers, making structural reliability, adaptability, and high space efficiency critical criteria for material procurement teams.
As retail models adapt, display fixtures must support both consumer shopping experiences and rapid order pick-and-pack workflows. High-capacity modular retail racks allow retailers to showcase merchandise on lower shelves while keeping safety-stocked pallets above. This requires display systems engineered with structural safety margins similar to industrial warehouse racking.
Environmental sustainability is a core consideration in B2B procurement. DuraRacks employs non-toxic, TGIC-free electrostatic powder coatings. This process reduces volatile organic compound (VOC) emissions during production and results in a durable, scratch-resistant surface finish. Components are tested to withstand 500 hours of continuous salt spray, providing corrosion protection in high-humidity regions, marine shipping conditions, and cold-chain facilities.
Industrial racks deployed in regions prone to seismic activity must be engineered to resist horizontal and vertical ground accelerations. Our dedicated team of 68 engineering specialists utilizes Finite Element Analysis (FEA) to simulate structural responses under seismic loads. By configuring custom upright dimensions, structural floor anchorage, and heavy-duty seismic baseplates, we ensure compliance with localized building safety codes in North America, Western Europe, and Australia.
At DuraRacks, quality control is integrated throughout the manufacturing process. Our 45 certified QA personnel implement inspections and material tests at every stage, from raw coil verification to final product packaging, ensuring compliance with international ISO9001, CE, and FEM standards.
We perform ultrasonic flaw detection on load-bearing weld seams (including baseplates and beam-end connectors) to verify penetration depth and structural integrity, preventing failure under heavy load conditions.
Incoming structural steel batches undergo destructive tensile tests to verify yield strength (MPa), ultimate tensile strength, and elongation properties, ensuring alignment with specification certificates.
Racking assemblies are subjected to physical load tests exceeding rated capacities by 1.5x. We measure elastic and plastic deflections under these conditions to confirm safety margins before finalizing production runs.
Every production run is assigned a unique batch tracking number linked to raw steel mill certificates, operator logs, paint thickness records, and final inspection checklists, enabling full traceability throughout the product lifecycle.
We serve a diverse international clientele, adapting our design and shipping processes to meet the operational demands of different industries and logistics markets.
High-volume distribution centers require industrial warehouse racking systems with high durability and load capacity. DuraRacks designs custom, high-density pallet and mezzanine racking configurations that optimize vertical clearance, improve picking cycle times, and support integration with automated storage and retrieval systems (ASRS).
Operating in environments down to -30°C requires specialized material design. Standard carbon steels can experience low-temperature brittleness under high stress. We utilize specific low-temperature steel grades combined with frost-resistant electrostatic powder coatings to prevent corrosion and structural degradation in refrigerated and frozen food storage facilities.
In consumer-facing environments, display aesthetics, modularity, and durability are key considerations. Our retail gondola lines and modular metal shelving feature double-sided configurations, adjustable shelf heights, and integrated signage options, enabling dynamic store layouts that help maximize sales per square foot.
Storing heavy industrial components and tooling requires durable racks. Our structural steel pallet racking systems feature heavy-duty beam profiles and reinforced column designs, providing load capacities up to 5,000 kg per level to support heavy loads and high-capacity industrial demands.
