Engineered for immediate integration into heavy manufacturing, steel distribution, and lumber yards across Illinois and the Midwest logistics corridors.
As the primary freight and logistics crossroad of North America, the greater Chicago metropolitan area (encompassing Cook, Will, and DuPage Counties) serves as a critical junction for heavy manufacturing, metal distribution, and primary building supply logistics. Warehousing facilities along the I-80, I-55, and I-94 corridors demand structural integrity that can withstand high-throughput operations, heavy payload requirements, and stringent municipal safety regulations.
Cantilever racking systems are unique in their capability to store long, awkward, or non-uniform materials such as structural steel columns, PVC piping, architectural lumber, and sheet metal plates. Unlike standard selective pallet racks, cantilever systems eliminate the front column barrier, providing uninterrupted horizontal access for heavy material handlers, side loaders, and overhead cranes.
Comparing production techniques, steel grades, and load distribution characteristics to design compliant, fail-safe storage systems.
We supply both Roll-Formed Steel (high-yield cold-rolled profiles suitable for light-to-medium long components) and Structural Steel I-Beams (hot-rolled, wide-flange profiles designed to absorb severe forklift impacts and carry up to 20,000 lbs per column side). Structural columns are fabricated using heavy channel steel with welded steel bases to prevent structural fatigue under massive deflection loads.
Arms are engineered with a specific upward pitch (typically 2% to 4%) to compensate for natural steel deflection when under load. Arm-to-column connections are secured using high-strength grade-8 bolts or pivot pins to prevent vertical shear. Optional arm accessories include pipe stoppers, end lips, and wire-mesh decks for loose storage.
The base member acts as the anchor center for the vertical column. Utilizing oversized anchor baseplates, our systems are secured using dynamic expansion bolts directly into reinforced concrete slabs (minimum 6" slab thickness, 3000-4000 PSI capacity), meeting strict seismic and floor loading parameters.
Engineered for extreme loading profiles, harsh manufacturing environments, and heavy-gauge industrial storage applications.
A world-class manufacturing facility operating with advanced technology, strict compliance protocols, and a resilient global supply chain footprint.
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.
Mitigating compliance risk through proactive adherence to international material testing and regional layout mandates.
The Rack Manufacturers Institute (RMI) sets forth design parameters governing the construction of industrial steel cantilever systems (ANSI MH16.3). Durack ensures that every column and arm configuration undergoes advanced Finite Element Analysis (FEA) to confirm safety indices under dynamic load environments.
Key requirements include clear structural capacity labeling displayed on each racking run and calculating dynamic deflection limits (L/180 max for cantilever arm length) under worst-case loading curves.
Industrial yards in the Midwest face highly variable seasonal weather conditions, requiring specialized surface finishes. We offer high-durability electrostatic thermoset powder coatings for internal dry warehouses, and Hot-Dip Galvanizing (HDG) conforming to ASTM A123 guidelines for raw lumber yards, plumbing hubs, and outdoor fabrication yards.
HDG coating guarantees a thick zinc barrier layer that self-heals when scratched, preventing sub-surface oxidation and maintaining structural integrity over decades of exposure.
Additional specifications, configurations, and pricing variants built for regional warehouse facilities.
