Explore our top-selling industrial structural storage solutions engineered to double operational footprints safely.
Worldwide logistics hubs are facing unprecedented challenges: skyrocketing land costs, tightening municipal zoning regulations, and the explosive growth of regional fulfillment networks. To stay competitive, contemporary logistics structures must look upward. Industrial warehouse storage rack mezzanine systems represent the most cost-effective structural solution to optimize internal vertical clearances without undergoing expensive physical building expansions.
By leveraging rack-supported multi-level systems or structural steel platforms, enterprises can double or even triple their usable area. This approach reduces overall facility overhead per square meter and minimizes operational footprint, improving throughput efficiency in high-density warehousing environments.

High-Quality Industrial Racking Solutions Designed and Manufactured Since 2014.
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.
Visualizing our standard-compliant manufacturing stages, utilizing structural engineering standards to ensure zero deflection defects.
How customized structural mezzanines address distinct layout and regulatory demands across key industries.
High-speed throughput demands clear floor layouts on the bottom level for AGVs (Automated Guided Vehicles) and conveyor integration, while upper levels handle high-density small-item picking. Multilevel mezzanine racks maximize product assortment capacities without increasing horizontal footprints.
Automotive supply structures require robust load-bearing ratings for dense cast iron parts, molds, and mechanical assemblies. Heavy-duty Q355B H-beam platforms support structural point loads up to 1,500 kg per square meter, easily accommodating heavy toolboxes and machinery.
Operating costs in cold-chain logistics are extraordinarily high. Maximize storage volume using heavy-duty galvanized structural mezzanines. Open steel mesh planking facilitates continuous vertical airflow, preventing cold pooling and minimizing refrigeration cycle load times.
A look at the raw material integration, automation, and engineering expertise that provide Chinese suppliers with a global cost advantage.
Sourcing industrial mezzanine systems from China offers notable structural and economic advantages. Factories like Durack leverage close proximity to major domestic steel mills, securing premium Q235B and Q355B structural grades at competitive rates. This close supply chain integration reduces raw material markups from the outset.
In addition to material access, high manufacturing efficiency is driven by automation. Our facilities utilize robotic welding stations, continuous roll-forming lines, and electrostatic powder coating plants to minimize direct labor costs. This standardizes structural tolerances, ensuring consistent quality and alignment during field assembly.
By partnering with a direct manufacturer, buyers work directly with in-house R&D departments. This simplifies the process for customized structural layouts, seismic load calculations (SDC A-F), and regional compliance configurations, avoiding costly modifications down the line.
Key considerations for international structural approvals, seismic ratings, and safety configurations.
Different regions require specific seismic design considerations. In the US, projects must comply with the International Building Code (IBC) and RMI guidelines. In Europe, EN 1993 (Eurocode 3) governs steel structures. We design dynamic configurations tailored to these regional specifications.
Deflection calculation is critical for platform stability. Structural steel beams should not exceed the L/240 deflection limit under live loads, while conveyor-supporting frames are designed to L/360 or tighter specifications to prevent operational vibration issues.
For safety and compliance, multi-level attic systems must integrate compliant walkways, safety handrails, kickplates, and emergency stairs. Open grid deck designs ensure fire sprinkler systems can penetrate all levels in accordance with NFPA 13 standards.
Our structural design engineers address key technical questions to help guide your procurement process.
A structural steel platform mezzanine relies on heavy H-beams and square columns, creating large open spaces below for operations, forklift traffic, or office layouts. A rack-supported mezzanine uses standard upright racking frames as the primary load-bearing columns. This option is highly cost-effective when the lower level is dedicated to palletized inventory storage.
We use Finite Element Analysis (FEA) software to model structural loads, wind forces, and seismic activity based on project requirements. In production, we run ultrasonic weld tests, paint thickness evaluations, and physical load testing to confirm yield strengths match Q235B/Q355B standards.
For typical indoor storage facilities, we apply an electrostatic powder coating to a thickness of 60 to 80 microns. For high-humidity environments, chemical manufacturing plants, or outdoor applications, we recommend hot-dip galvanizing to prevent corrosion.
Yes. Our engineering department specializes in designing customizable layouts. We provide drawings that accommodate conveyor lines, vertical reciprocating conveyors (VRCs), pallet drops, safety gates, and maintenance access points.
