Precision-engineered medium duty and heavy duty pallet racking, AS/RS, mezzanine, and shuttle solutions.
Uncompromising metallurgical standards, continuous roll-forming engineering, and rigorous B2B export compliance.
We source prime cold-rolled steel coils directly from tier-one state steel mills (Baosteel, Shougang). Every column profile undergoes tensile testing to verify Q235B and Q355B yield strength compliance.
State-of-the-art continuous roll-forming production lines ensure exact pitch accuracy (50mm/75mm/50.8mm options), consistent geometry, structural rigidity, and seamless beam-connector locking.
Engineering calculations strictly adhere to international codes including ANSI MH16.1 (RMI), EN 15512:2020, FEM 10.2.02, and AS 4084-2012. Load ratings are independently tested and certified.
18-stage chemical wash, phosphatizing pretreatment, and thermosetting epoxy powder coating (60-80μm thickness) guarantee high salt-spray resistance and structural durability in humidity or cold rooms.
Customized steel-strapped export bundling, corner protections, and containerized loading plans minimize ocean transit damage while optimizing container cube space to reduce ocean freight costs.
Our dedicated engineering office provides structural calculation reports, 3D BIM integration, building load safety assessments, and tailored layout drawings within 24–48 hours.

As global supply chains demand higher throughput, optimized footprint utilization, and strict workplace safety, selecting the right industrial racking manufacturer is a critical strategic decision for logistics operators, warehouse managers, and B2B importers. China's manufacturing sector for warehouse equipment has evolved beyond basic fabrication into high-precision structural engineering, governed by rigorous international standards such as ANSI MH16.1 (RMI), EN 15512, FEM 10.2.02, and AS 4084.
Medium-duty pallet racking and hybrid shelving systems bridge the operational gap between manual hand-pick shelving and high-tonnage heavy-duty beam racks. Engineered for uniform loads ranging from 200kg up to 800kg per level, medium-duty solutions provide optimal versatility for high-mix low-volume distribution centers, e-commerce micro-fulfillment hubs, automotive spare-parts stores, and light manufacturing plants.
Modern warehouse design increasingly integrates Autonomous Mobile Robots (AMRs) and automated forklifts. Racking structures must maintain strict dimensional tolerances, perpendicularity, and floor anchoring stability to allow optical sensors and navigation systems to align perfectly with pallet slots. Chinese exporters are designing upright frames with reinforced footplates and high-precision punch patterns specifically tailored for automated robotic pickers.
With global installation labor costs rising, global buyers prioritize interlocking teardrop or hook-in beam connectors that eliminate complex bolted structural connections without compromising dynamic stability. Medium duty and heavy duty pallet racks manufactured in China feature cold-formed interlocking connectors equipped with safety drop-locks that prevent accidental dislodgement during rapid forklift maneuvers.
Environmental standards in Europe and North America require suppliers to adhere to zero-VOC, heavy-metal-free electrostatic powder coating processes. Leading Chinese exporters utilize closed-loop water treatment systems and automated powder spray lines that guarantee uniform coating thickness, high impact resistance, and minimal environmental impact throughout the manufacturing lifecycle.
The industrial storage landscape is undergoing rapid digitization and structural refactoring. Key developments transforming the sector include:
When procuring medium-duty pallet racking from China, overseas procurement directors should look beyond unit pricing and perform rigorous technical audits across five key operational areas:
1. Steel Mill Traceability: Ensure the manufacturer provides Mill Test Certificates (MTC) verifying carbon content, yield strength, and tensile limits for cold-rolled steel coils (Q235B/Q355B equivalent to ASTM A36 / Grade 50).
2. Punching & Profile Consistency: Upright columns must be produced on continuous automated roll-forming machines equipped with CNC punch stations. Irregular hole pitches create structural twist during installation and weaken vertical column buckling limits.
3. Weld Quality & Robotic Automation: Structural beam-to-connector joints must be welded using robotic CO2 gas-shielded welding lines to avoid human error, porosity, or incomplete penetration.
4. Load Testing & Finite Element Analysis (FEA): Request FEA simulation reports and physical destructive load testing data demonstrating a safety factor of at least 1.5 to 1.65 in compliance with RMI and FEM specifications.
5. Export Packing Standards: Inadequate ocean freight packaging can lead to paint scratching, profile deformation, or rust. Insist on heavy-duty wooden dunnage, steel strapping, corner edge protectors, and waterproof plastic wrapping.
Technical clarity on engineering specifications, export logistics, and system customization.
Medium duty racking typically utilizes lighter cold-rolled steel column profiles (such as 55×47mm or 60×50mm) engineered for shelf loads between 200kg and 800kg per layer. It is primarily accessed manually or with light stackers. Heavy duty pallet racking employs thicker structural or tubular uprights (80×60mm up to 120×95mm, Q235B/Q355B steel) built for full pallet loads ranging from 1,000kg to over 4,000kg per tier, requiring standard counterbalanced or reach forklifts.
Our racking products can be fully custom-engineered in accordance with global regulatory requirements including ANSI MH16.1 (Rack Manufacturers Institute - RMI), European Standard EN 15512:2020, FEM 10.2.02, and Australian Standard AS 4084-2012. Structural analysis and seismic safety factors are calculated based on your specific geographical installation location.
To produce an optimized structural quotation, we require: (1) Pallet footprint dimensions and maximum unit load weight; (2) Available clear building height and obstacle locations (sprinklers, lights, trusses); (3) Forklift model, maximum lift height, and minimum aisle turning radius; (4) Preferred inventory access method (FIFO or LIFO); and (5) Concrete floor slab thickness and seismic zone data.
Uprights are pre-assembled or knocked down into dense bundles wrapped in protective plastic film with heavy-duty steel corner protectors. Beams are stacked face-to-face on custom wooden/steel skids to protect connector tabs. Accessories and small hardwares are securely packed in reinforced wooden cases labeled with part codes corresponding directly to installation assembly drawings.
Yes. For cold storage facilities operating down to -30°C, we specify low-temperature ductile Q355B steel to prevent brittle fracture. For outdoor or high-corrosion applications, we offer Hot-Dip Galvanized (HDG) treatments complying with ISO 1461, ensuring zinc coating thickness exceeds 60-80 microns for decades of rust protection.
