Explore our structural-grade heavy-duty and medium-duty racking systems, engineered for maximum load capacities and operational safety.
In modern industrial logistics, storage systems are no longer regarded as static steel components. Driven by high-intensity fulfillment schedules, stringent labor safety laws, and automated retrieval dynamics, the demand for ergonomically engineered racking has surged globally.
True ergonomic racking integrates advanced mechanical physics, spatial design, and human factors. It focuses on limiting musculoskeletal load during picking phases, reducing structural fatigue, and optimizing interaction heights. By engineering storage shelves that adapt to human reach envelopes and material handling machinery, businesses can significantly reduce down-time, decrease warehouse injuries, and accelerate picking throughput by up to 28%.
As a premier exporter in this industry, we balance high-yield steel processing with precision architectural layout designs, assuring that every rack system satisfies both international quality expectations and strict structural compliance metrics.
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.
Analyzing localized demands, structural regulations, and industry vertical applications across global economic zones.
Operating as an international supplier requires compliance with distinct regional building and safety codes. In North America, our designs align with the ANSI/RMI MH16.1 specification (Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks). In Europe, we adjust raw material dimensions to conform to standard European structural norms, including EN 15512 and FEM 10.2.02. Additionally, in the Asia-Pacific region, we test our structural systems to comply with the seismic resistance configurations outlined in AS 4084-2012.
Our warehouse racking systems utilize advanced corrosion prevention coatings, engineered to withstand challenging environments. The steel profiles undergo a multi-step chemical pre-treatment process, including hot zinc phosphating, to ensure complete rust removal and provide an optimal surface for adhesion. We then apply an electrostatic powder coat of high-durability epoxy-polyester thermosetting resin, which is baked at 200°C. For extreme humidity or cold room operations, we offer hot-dip galvanized finishes complying with ISO 1461, yielding a zinc barrier thickness of over 65 microns.
As warehousing transitions toward automation, we design our shelving profiles to integrate seamlessly with automated storage and retrieval systems (ASRS) and autonomous mobile robots (AMRs). This requires strict structural tolerances during roll forming to prevent warping under mechanical loads. The clean lines, precise beam alignment, and consistent load tolerances allow sensor-guided automated systems to operate reliably without the risk of collision or structural misalignment.
Our ergonomic focus is engineered directly into our component designs. Upright posts feature rounded edges to prevent injury, while beam lock clips protect against accidental fork displacement during loading. The beam heights are designed for quick adjustability using boltless, rivet-style connections, allowing users to modify shelf heights without specialized tools. This structural flexibility helps maintain natural physical posture, reducing strain and improving overall workspace safety.
Our long-term R&D program focuses on advancing structural capacity, safety technology, and materials science to meet the demands of modern warehousing.
Utilizing high-tensile cold-rolled steel micro-alloys (such as niobium-titanium hardened alloys) to reduce overall rack weight while maintaining high load-bearing capacity. We use Finite Element Analysis (FEA) to simulate complex stress distribution under dynamic loads.
Integrating micro-sensor brackets into load-bearing beams to monitor deflection in real time. These smart systems are designed to send alerts to warehouse management databases if safe load capacities are exceeded or if a structural collision occurs.
Developing bio-based, VOC-free coating powders that cure at lower temperatures to reduce carbon emissions. We are also optimizing modular designs to ensure all racking components are easily recyclable at the end of their service life.

We primarily construct our upright profiles and load-bearing beams from Q235B and Q345B structural carbon steel. Q345B is selected for high-load applications due to its high yield strength (345 MPa) and performance under dynamic stress, which is critical for long-span shelves and seismic-resistant configurations.
We determine load capacity using the Finite Element Method (FEM) in accordance with the EN 15512 and ANSI/RMI MH16.1 standards. The deflection limit for our beams under maximum load is calculated at L/200 (where L is the length of the span), ensuring structural safety and stability under full load.
Boltless rivet connections allow for quick assembly and easy shelf-height adjustments without specialized tools. Unlike permanently welded systems, these modular configurations can be easily rearranged to accommodate changing stock dimensions, reducing installation time and overall maintenance costs.
For high-humidity or cold storage environments, we offer hot-dip galvanized coatings (standard ISO 1461) or zinc-rich primer basecoats under a high-durability powder topcoat. This dual barrier prevents moisture infiltration and rust formation, maintaining structural integrity at temperatures down to -30°C.
Yes. Supported by our 25-engineer R&D center, we offer custom OEM/ODM solutions tailored to specific layout requirements. This includes specialized rack configurations, custom vertical pitches, custom powder-coat color schemes, and adjusted beam loading capacities to match specific material handling needs.
Our 45-member QA/QC team performs a strict multi-stage inspection process. This includes verifying steel coil thickness, inspecting welding penetration using automated ultrasonic testing, measuring powder coat thickness (standard target: 60-80 microns), and conducting load-bearing fatigue assessments on random batch samples.
