Custom Heavy-Duty Metal Storage Rack Fabrication Case Study | Australian Client | DEEPLINK
1. Client Background & Initial Requirements
In November 2025, A professional industrial warehousing solutions provider based in Melbourne, Australia, submitted a custom inquiry for heavy-duty metal racks through the DEEPLINK official website. The client supplies integrated warehousing systems to numerous large e-commerce warehouses and manufacturing plants across Australia. For this project, they required 120 sets of custom heavy-duty tiered metal racks for a newly contracted cold chain logistics center in western Melbourne, intended to store palletized frozen food and industrial components.
Core Client Requirements:
- Load capacity: Compliant with Railway Industry Standards
- Material specification: Q235B hot-rolled steel plate, thickness ranging from 3mm to 8mm
- Surface treatment: Outdoor-grade electrostatic powder coating in RAL5015 Sky Blue
- Delivery timeline: Complete production and ship to Port of Melbourne within 45 days
- Certification requirements: Provide ISO9001 quality certification documents and product load test reports

2. Technical Coordination & DFM Analysis
After the client uploaded their initial 3D STEP file, DEEPLINK’s engineering team completed a free Design for Manufacturability (DFM) analysis within 24 hours and proposed three key optimization suggestions:
- Replace partial right-angle welds with rounded transitions to reduce stress concentration and enhance overall structural strength
- Optimize the punching layout of rack columns, using progressive die stamping instead of single punching to reduce unit production time by 40%
- Add reinforcing ribs at beam-column connections to increase load capacity by 20% without additional material costs
3. Production Process & Quality Control
This project utilized DEEPLINK’s full-process integrated metal fabrication services, with core processes including:
- Laser Cutting: 6000W high-power fiber laser cutting machines were used to cut 8mm thick column plates, with tolerances controlled within ±0.1mm
- CNC Bending: 160-ton CNC press brakes completed high-precision bending of columns and beams, with angle deviation ≤±0.5°
- Welding & Assembly: CO2 gas shielded welding was employed, with 100% visual inspection
- Load Testing: 3 randomly selected finished units underwent full-load static load testing for 72 consecutive hours, with no deformation or cracking observed
Production strictly followed the ISO9001:2015 quality management system, with 39 quality inspection nodes set up throughout the process to ensure every rack met client requirements.
4. Surface Treatment & Export Packaging
Considering Australia’s coastal high-corrosion environment, DEEPLINK implemented a triple anti-corrosion treatment process:
- Overall sandblasting rust removal of workpieces, reaching Sa2.5 grade standard
- Application of epoxy zinc-rich primer with a minimum thickness of 60μm
- Final coating of outdoor-grade polyester powder in RAL5015 Sky Blue, with a minimum thickness of 80μm
For packaging, export-standard packaging suitable for ocean shipping was used:
- Each rack was disassembled into three parts: columns, beams, and shelves
- Individually wrapped with bubble wrap and stretch film to prevent scratches during transportation
- Secured to wood pallets with steel strapping
- Clear shipping marks and packing lists attached to pallets for easy customs clearance and unloading by the client

5. Delivery & Client Feedback
In January 2026, all goods were successfully shipped from Tianjin Port and arrived at Port of Melbourne 35 days later. DEEPLINK tracked the logistics status throughout the process and provided the client with a full set of customs clearance documents in advance, including commercial invoices, packing lists, bills of lading, certificates of origin, and quality certification certificates.After receiving the goods, the client gave high praise for both product quality and delivery speed.
