Industrial Excellence

Ningbo Xinmiao Storage Equipment Co., Ltd.

Established in 2015, Ningbo Xinmiao Storage Equipment Co., Ltd. has developed into a premier global manufacturing facility specializing in high-capacity pallet racking, automated mezzanine integration, and customized heavy-duty industrial shelving. Over 14 years of dedicated industry experience enables us to engineer storage configurations that meet and exceed structural requirements in challenging distribution and production centers globally.

Operating a modernized facility of over 35,000 square meters, we achieve optimal manufacturing efficiency through vertical supply integration, employing 25 Quality Control (QC) engineers and 18 dedicated Research & Development (R&D) structural engineers. This engineering focus allowed us to roll out 45 new structural configurations last year, expanding our global footprint across North America, Europe, Southeast Asia, and the Middle East.

  • Compliance & Safety: Full structural testing complying with EN 15512, RMI guidelines, and local regulations.
  • High-Tensile Cold-Rolled Steel: Grade Q235B and Q355B structural elements for high yield strength and seismic safety.
  • End-to-End Traceability: Individual coil testing certifications matched with full weld non-destructive testing (NDT).

OEM/ODM R&D Focus

Our 18 structural R&D specialists deploy Finite Element Analysis (FEA) to simulate local environmental variables such as wind loads, seismic movements, and dynamic floor weights to optimize column profile and beam hook thickness.

Intense QC Infrastructure

25 dedicated quality controllers handle incoming material validation, automated weld inspections, and cross-cut tape powder-coating adhesion testing to protect systems against wear and oxidation.

Macro Industry Solutions & Global Footprint

Custom structural engineering designed to support modern high-throughput logistics, supply-chain storage systems, and automation setups.

3PL & Cold Chain Integration

For high-turnover third-party logistics (3PL) facilities and cold chain operations. We optimize aisle geometry to improve volumetric loading. Structural steel elements are coated with specialized low-temperature powder coatings to prevent embrittlement and cracking down to -30°C.

High-Density Shuttle Storage

Our radio shuttle and automated storage and retrieval systems (AS/RS) provide precision racking configurations with dimensional tolerances under ±1mm. This ensures smooth, uninterrupted shuttle execution and protects electronic warehouse components.

Automotive & Mould Warehousing

Specialized heavy mould storage solutions capable of bearing point loads exceeding 3,000 kg per level. These units feature pull-out shelves and secure interlocking pins to guarantee safety during overhead crane loading operations.

End-to-End Precision Manufacturing Workflow

From dynamic computer engineering to mechanized powder coating, our facility handles every step internally to guarantee quality control.

Structural Integrity & Steel Optimization

Heavy load systems require rigorous safety margins. Xinmiao racking uses high-tensile steel cold-formed into specialized profile channels to maximize structural stability and strength. Our design team applies Finite Element Method (FEM) analysis to calculate upright frame loading capacities, ensuring configurations perform safely under full load conditions.

We provide full verification calculations covering deflection limits, seismic load adjustments, and frame shear calculations for all bespoke warehouse solutions, assuring local building inspectors of complete structural compliance.

  • Upright Profile Range: Section widths of 80mm, 90mm, 100mm, and 120mm, with material thicknesses up to 3.0mm.
  • Beam Safety Locks: Patented 3-hook and 4-hook connectors with automatic security pins to prevent accidental dislodgement.
  • Epoxy Powder Coating: Applied at a thickness of 60 to 90 microns after a multi-stage chemical pretreatment, providing corrosion resistance.

Local Support & Compliance Standards

Global logistics demands structures engineered to pass local building inspection codes and safety guidelines.

North America (RMI & ANSI)

We supply structural assemblies designed to meet Rack Manufacturers Institute (RMI) standards and AISC specifications. This ensures compliance for projects throughout the United States and Canada.

European Markets (EN 15512)

Fully compliant with EN 15512 and FEM 10.2.02, featuring the CE mark where required. This compliance guarantees safety clearances and load placards for warehouses in the UK and European Union.

Australia (AS4084-2012)

Our structures comply with the physical and structural testing requirements of AS4084-2012, specifying structural tolerances and impact calculations for mining, industrial, and agriculture projects.

The Automation Frontier

Modern supply chains are evolving. In response, Xinmiao is focusing on smart integration, manufacturing systems designed to integrate with automated guided vehicles (AGVs) and autonomous mobile robots (AMRs).

Our latest heavy-duty racking columns feature pre-punched sensor brackets and wire routing channels. This design simplifies the installation of automated height scanners and load verification sensors directly on the frame.

Technology Roadmap

Future-Proofing Warehousing

Over the next five years, Ningbo Xinmiao is updating manufacturing technology to support smart logistics. Our R&D team works closely with automated warehousing systems (AS/RS) integrators to ensure alignment between structural racks and robotic systems.

  • Tighter Manufacturing Tolerances: Upgrading cold-rolling lines to reduce structural deviation tolerances to within ±0.5mm.
  • Pre-Configured Shuttle Rails: Integrated track profiles for fast assembly of shuttle systems.

Industrial FAQ & Specification Verification

Answers to technical questions regarding load capacity, structural safety, export regulations, and customization capabilities.

Q: How do you verify the load-bearing capacity of your racking systems?
A: Every profile configuration undergoes Finite Element Analysis (FEA) alongside physical load testing. We perform ultimate-load compression and bend testing on our profiles to ensure a 1.5 to 1.8 safety factor. This testing complies with EN 15512 and RMI standards.
Q: Can you customize racking systems to meet specific local seismic codes?
A: Yes. Our engineering team calculates specific seismic profiles based on local geological data. We adjust footplate dimensions, column profile wall thicknesses, and beam connector designs to meet local seismic safety requirements.
Q: What materials and finishes do you use to prevent corrosion?
A: We utilize certified Q235B and Q355B cold-rolled steel. For corrosion protection, our automated line applies a multi-stage chemical pretreatment, followed by an electrostatic epoxy powder coating baked at high temperature, achieving a cured thickness of 60 to 90 microns.
Q: What is the typical lead time for custom OEM manufacturing?
A: Standard design approval and production takes 20 to 30 days, depending on project scale and customization requirements. This timeframe includes material procurement, profile rolling, automated welding, surface coating, and pre-shipment quality inspection.
