Engineered to absorb seismic stresses in New Zealand's active regions, our initial selection represents the pinnacle of high-load industrial safety and density.
New Zealand's warehousing sector is undergoing a massive structural transformation. Driven by the expansion of international third-party logistics (3PL) networks, exponential growth in e-commerce, and high demand in agricultural and dairy exporting channels, storage spaces have to work harder than ever. Spatial constraints in prime industrial zones—such as South Auckland (Wiri, Airport Oaks, and Mount Wellington), Tauranga, and Christchurch (Hornby and Sockburn)—have pushed land prices and lease costs to record levels.
Consequently, warehouse operators are moving vertically, deploying high-bay selective pallet racking systems to maximize cubic capacity. Unlike standard environments, New Zealand's unique tectonic profile demands rigorous engineering analysis. The country sits along the boundary of the Pacific and Indo-Australian plates, making seismic resilience the absolute priority for warehouse safety. Substandard racking imports without certified load calculations represent not only a regulatory liability but a profound operational risk.
From Canterbury (high peak ground acceleration rates) to the Wellington Fault lines, standard European or American configurations require structural modification to survive dynamic seismic shear forces.
Achieving regional structural sign-offs requires certified engineering documentation (PS1/PS3 Producer Statements) verified by local Chartered Professional Engineers (CPEng).
Our manufacturing processes are calibrated directly to oceanian engineering codes, ensuring every component stands resilient during high-energy seismic activity.
We manufacture in strict compliance with the updated AS 4084 steel storage racking standard, utilizing higher thickness tolerances, dual-connector lock systems, and modified upright deflection limitations.
We calculate lateral structural responses against the seismic coefficients specified in NZS 1170.5. Heavy-duty baseplates and heavy floor anchorages are mandatory to prevent frame overturning.
We supply verified material mill test certificates (demonstrating structural yield strength minimums of 235MPa to 355MPa) and calculation files required by NZ councils for building consent issuance.
A critical technical distinction in seismic engineering is the choice of steel raw material. Our manufacturing lines primarily process raw structural steel grades Q235B and Q355B (equivalent to international standards S235JR and S355JR). Q355B provides a minimum yield strength of 355 MPa, delivering superior structural load-bearing capacity with lower self-weight. This high-tensile properties are essential for high-rise selective racks or dynamic drive-in racking, where structural elasticity helps absorb seismic shocks without brittle weld failure.
Engineered to support heavy unit loads and dynamic operational frequencies across cold storage, bulk distribution, and manufacturing sites.
Our manufacturing powerhouse ensures maximum durability and precise tolerances. Underpinned by ISO9001 and strict QA pipelines, we bring premium storage systems to global markets.
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.
For Kiwi food distributors and primary export sectors, cold storage is the critical link. Our customized racking supports are zinc-plated or treated with high-durability epoxy-powder finishes to withstand persistent sub-zero moisture levels without oxidation.
We develop bespoke beam profiles and unique height-to-depth configurations directly tailored to narrow aisle material handling equipment. Integrated layout designs ensure smooth navigation for modern articulated and reach forklifts.
Each industry has unique load distribution and space parameters. Our engineers approach warehouse design from a multi-variant structural standpoint:
By assessing parameters like pallet footprints, load limits, and turnover rates, Durack translates macro design targets into robust storage infrastructure.
The alignment of mechanical racking components with advanced autonomous technologies defines the future of smart industrial warehousing.
As robotic warehouse systems grow in NZ, rack deflection tolerances must be kept within millimeter ranges. We use Finite Element Analysis (FEA) to verify framing under strict dynamic loads.
Our future-ready designs accommodate micro-sensors placed on crucial bracing elements to monitor stress loads and alert warehouse managers of forklift impact damage in real time.
We prioritize lower carbon footprint raw materials, leveraging energy-efficient induction curing during powder coating processes to meet environmental standard certifications.
Our extensive collection of industrial storage models covers everything from high-density drive-in systems to flexible longspan options.
