The finished rack improved handling efficiency while reducing overall logistics costs.
The manufacturing steps
A rack is only as good as the process behind it. Each stage below is done in-house, which is what lets us hold tolerances and fix problems without going back through a third party.
What each stage controls
| Stage | What it determines |
|---|---|
| Tube cutting | Dimensional accuracy of every frame member |
| Welding | Structural strength and the verified load rating |
| Powder coating | Corrosion resistance and finish durability over many cycles |
| Assembly | Fit of nests, arms, casters and protection to the actual part |
| Final inspection | Dimensions, welds, finish and function before shipment |
Why in-house matters for battery racks
Battery racks carry heavy, sensitive and regulated cargo, so structure and insulation cannot be improvised late in the build. Lithium batteries are classed as dangerous goods in transport under frameworks such as the UNECE model regulations, and the rack is one part of a compliant system. Our process runs to ISO 9001. See the design considerations in our guide to returnable racks for EV battery packs.

Frequently Asked Questions
- What manufacturing steps does a custom rack go through?
- Five in-house stages: tube cutting for dimensional accuracy, welding for structural strength, powder coating for corrosion resistance, assembly to fit nests and hardware to the real part, and a final inspection of dimensions, welds, finish and function before shipment.
- Why does in-house manufacturing matter?
- Because the engineers who designed the rack control every stage, tolerances hold and problems get fixed directly instead of being routed through a third-party workshop. It also removes the trading-company margin and shortens the loop when a design revision is needed.
- How long does a custom battery rack take?
- Plan on roughly 7–15 days for a tested sample and about 25–45 days for mass production, depending on quantity and finish, plus ocean transit. We provide a quotation within 24 hours of receiving your drawings or part data.
- Are battery racks subject to transport regulations?
- Lithium batteries are classed as dangerous goods in transport under frameworks such as the UNECE model regulations. The rack is one part of a compliant system — it handles structure, insulation and fixturing — so always confirm the full requirements with your logistics and safety teams.
- Can you build to our drawings or do you design from scratch?
- Both. We build to your drawings as an OEM, or develop the design ourselves from your part data, load and handling method as an ODM. Either way we build and load-test a sample for approval before committing to mass production.
