Engineered and manufactured to support intense load configurations under strict compliance with CE directives and structural safety criteria.
The paradigm of industrial warehousing is shifting rapidly. Rapid global trade networks, high e-commerce processing loads, and automated stock distribution call for versatile, high-density storage configurations. Basic structural shelves are no longer sufficient to meet these heavy-duty requirements. Today’s industrial operations require certified longspan racking architectures capable of supporting heavy loads while maintaining maximum structural stability.
Longspan shelving systems act as the core framework for warehouses managing medium to heavy loads. By avoiding the extreme costs of structural heavy pallet configurations, these modular platforms allow logistics managers to scale, adapt, and restructure storage floors dynamically. Our CE-certified longspan units bridge the engineering gap between light-weight manual racks and massive automation storage, providing long-term reliability for demanding warehousing setups worldwide.
Providing high-precision engineering and structural reliability through a centralized manufacturing footprint.
Established in 2015, Shenzhen Yuanzhang Trading Co., Ltd. is a leading manufacturer and exporter specializing in heavy-duty warehouse racking and customized industrial storage systems. Operating out of a state-of-the-art 35,000 m² production facility, we bring 12 years of deep industry expertise and 8 years of dedicated international trade experience to global logistics and commercial storage projects.
Driven by technical excellence, our operations are backed by a robust research and development center staffed with 25 expert R&D engineers. Demonstrating our strong commitment to innovation, we launched over 150 new storage solutions last year alone. We offer fully versatile OEM/ODM custom options, including specialized dimensions, weight capacity adjustments, surface coatings, and modular structural designs to meet diverse client requirements. Quality and reliability form the foundation of our business. We enforce strict multi-stage quality control—utilizing advanced automated ultrasonic testing, raw material stress analysis, and load-bearing fatigue assessments executed by a dedicated team of 45 QA/QC inspectors.
Understanding the critical performance metrics, testing practices, and structural demands that influence procurement decisions.
We fabricate all uprights, beams, and ties from verified structural carbon steel (grades Q235B and Q355B). These alloys are selected for their high yield strengths and elongation parameters, which prevent sudden failure under extreme structural stress.
Racks receive an electrostatic powder coating cured at high temperatures. This forms a cross-linked polymer shell 60 to 90 microns thick, providing excellent resistance against impact, scraping, and chemical corrosion.
From automated roll forming lines to laser-monitored punching tools, our components maintain a tight dimensional tolerance of +/- 0.5mm, ensuring smooth assembly and stable load distribution.

| Compliance Standard | EN 15512 (FEM directives) & CE certification | Simplifies regulatory approval for site developments in EU regions. |
| Thickness Tolerances | Upright profiles: 1.5mm to 2.0mm; Box step beams: 1.5mm to 1.8mm | Provides maximum safety margins during load variations. |
| Salt Spray Resilience | Exceeds 500 hours (in accordance with ASTM B117 standards) | Suitable for cold storage installations and humid climates. |
| Assembly Formats | Adjustable boltless system with double-taper key lock connectors | Allows quick reconfiguration without special tools. |
Tailored configurations engineered for diverse industrial sectors, from retail fulfillment to heavy industrial manufacturing.
Fulfillment operations require quick, manual access to a wide range of inventory items (SKUs). Longspan storage systems allow you to integrate steel panels, wire decking, or chipboard layers to accommodate varying package sizes on a single level.
Engine blocks, exhaust pipes, and stamping dies require sturdy, reliable shelving. Our reinforced box step beams feature dynamic stiffening brackets that prevent twisting under heavy, localized loads.
Sub-zero warehouses need storage systems that resist low-temperature metal fatigue. We offer hot-dip galvanized longspan frames that remain stable and corrosion-free down to -40°C.
Our 25 R&D engineers design complete, custom solutions tailored to your facility's layout and workflow requirements:
Exporting industrial racks to strict international markets like Western Europe and North America requires strict adherence to safety standards. Our CE-certified longspan configurations undergo rigorous testing:
With a steady network of over 800 raw material and component suppliers, we maintain stable production cycles and consistent delivery times, even during challenging global freight conditions.
Whether you need custom clearance support in North America, assembly assistance in Western Europe, or distribution layouts in the Middle East, our technical teams provide 3D CAD schematics and detailed documentation to ensure seamless site approval.
Building next-generation storage systems ready for smart warehouses and automated logistics.
Future logistics centers rely heavily on Automated Guided Vehicles. Our custom frames are manufactured with wide clearances and consistent heights, allowing automated retrieval vehicles to navigate storage aisles safely.
We use zero-emission paint curing systems and low-carbon steel processes. This helps logistics developers meet environmental requirements and achieve LEED certifications.
We are currently developing smart load-monitoring brackets with integrated micro-sensors. These modules alert warehouse managers to unexpected stress loads and deflection values before they lead to structural failures.
Technical guidance from our R&D engineering department on planning, compliance, and material selection.
CE certification indicates that our longspan racks comply with EU safety, health, and environmental standards. Our structural frames meet key structural safety codes (including EN 15512 and EN 15620), confirming they can support certified maximum load limits without risking catastrophic failure.
Q355B is a low-alloy, high-strength steel with a yield strength of 355 MPa, compared to 235 MPa for Q235B. We use Q355B in high-capacity upright assemblies and heavy support structures to increase load capacity while keeping total rack weight manageable.
Yes, our longspan systems feature precision-formed steel profiles with consistent tolerances (+/- 0.5mm), making them fully compatible with Automated Guided Vehicles (AGVs) and standard stacker crane configurations.
Our standard coating thickness ranges from 60 to 90 microns. Applied electrostatically and thermoset cured, this barrier protects the steel core against moisture, oxygen, and chemical exposure, ensuring long-term durability in humid or unconditioned warehouses.
Our boltless racks feature tapered connectors that seat securely into column slots. This eliminates the need for hardware connections, reducing assembly times by over 50% while maintaining high structural rigidity.
