Repeat orders
Two ways a repeat order fails, and what stops each one
Batch drift
The third order arrives built to a different drawing than the first.
- MaterialBaosteel / Ansteel SPCC cold-rolled — one source fixed per batch, not whatever the mill has that week.
- ToolingThe same punches and press-brake tooling stay on the part for the life of the order.
- RouteA written process route, with full inspection before shipment and a certificate per unit.
Schedule slip
The date moves because a process left the building and came back late.
- ProcessCutting, forming, welding, coating, assembly and inspection sit in one 8,000 m² total facility (6,000 m² production workshop).
- RowContainment and cabinets arrive as one row, deployed in 2–3 weeks.
- PaperThird-party reports attached to the order, so less of the acceptance argument happens on site.
Process route
Eight steps, and every one of them has a name
This is the route the second batch is quoted against. The three marked checkpoints are the ones a buyer usually writes into his own purchase requirement.
-
01
Ingoing material inspection
100% incoming inspection.
-
02
CNC punching and press brake
Dimensional accuracy of ±0.5 mm on fabricated parts.
-
03
Robot welding and manual touch-up
Frame joints welded, then dressed by hand.
-
04
Degrease
Mill scale and oil removed before any coating.
-
05
Phosphating
Conversion layer, so the powder keys to the steel.
-
06
Electrostatic powder coating
Automated line, one colour per batch.
-
07
Assembly
Built to the approved drawing, doors and rails fitted.
-
08
Per-unit inspection before shipment
Full inspection, with a certificate per unit.
Acceptance
The lines that go into the purchase requirement
| Acceptance item | Value |
|---|---|
| Rack height | 42U = 2000 mm · 47U = 2200 mm |
| Height beyond 47U | 52U and above: custom / built to order |
| Width × depth | 800×1200 mm standard for high cable count; 600×1000 / 600×1100 / 600×1200 mm |
| Steel | Baosteel / Ansteel SPCC cold-rolled — one source fixed per batch |
| Uprights / doors | 2.0 mm uprights · 1.2 mm doors |
| Dimensional accuracy | ±0.5 mm (CNC punching and press brake) |
| Welding | Robot welding with manual touch-up |
| Surface finish | Degrease → phosphating → electrostatic powder coating, automated line |
| Incoming material | 100% incoming inspection |
| Front / rear door mesh | ≥75% / ≥60% |
| Static load | 1,000 kg standard · 1,500 kg on reinforced-frame models |
| Grounding continuity | Tested on every unit before shipment |
| Unit documentation | Full inspection before shipment, with a certificate per unit |
| Structural warranty | 5 years on the rack frame |
Row delivery
How a whole row arrives
Containment, doors, roof panels and the in-row cooling position are set out with the row, so the row is commissioned as one thing rather than assembled from four suppliers on the day.
Monitoring is a text and parameter story, not a screen: remote web access and SMS alerting are wired to the row controller, and the alarm names the row it came from.

Project record
Wangjialing coal mine data room retrofit — industrial site
An industrial project, labelled as one: the client operates a coal mine, not a cloud region. It is on this page because a retrofit inside a working room is the hardest version of the delivery problem this page is about.
- Scope
- Cold aisle containment retrofitted around a live cabinet row.
- Constraint
- The room stayed in service, so the work had to fit around production.
- Outcome
- Summer high-temperature alarms went to zero, with no interruption to operations.
Next step
Send the first batch, not a wish list
Send the first batch's drawing and the specification you signed off — we quote the second batch against the same route and the same inspection sheet.
Every request is either accepted or explicitly refused — never silently dropped.
