When you order Great Wall aluminum panels, what actually happens between paying your deposit and the container leaving port? Understanding the production process helps you plan your project schedule and spot a supplier who is cutting corners. Here is the full sequence.
The Production Timeline
| Stage | What happens | Typical time |
|---|---|---|
| 1. Order confirmation | Specs, drawings & deposit (usually 30% TT) confirmed | 1-3 days |
| 2. Material procurement | Aluminum coil & PIR chemicals sourced to spec | 3-7 days |
| 3. Coil coating | Aluminum coil PVDF-coated to your RAL color | 3-5 days |
| 4. Continuous lamination | Foam injected & bonded between faces on the production line | 3-7 days |
| 5. Cutting & profiling | Panels cut to your lengths, Great Wall joint profiled | 2-4 days |
| 6. QC & packing | Inspection, film protection, crating | 2-3 days |
| 7. Loading | Container loaded & documents prepared | 1-2 days |
Total production is typically 20-35 days from confirmed deposit to loaded container, depending on order size, color (custom RAL adds coating time) and factory workload.
Where Delays Actually Happen
- Custom colors – non-stock RAL needs a dedicated coating run
- Peak season – factory backlog before major holidays extends queues
- Spec changes mid-order – any change resets parts of the schedule
- SABER / documentation – first-time Saudi registration runs in parallel but can hold shipment if started late
Add Ocean Transit for Total Lead Time
| Route | Transit | Total (prod + transit) |
|---|---|---|
| Tianjin → Jeddah / Jebel Ali | 20-26 days | ~45-60 days |
| Tianjin → Ho Chi Minh / Jakarta | 5-10 days | ~25-45 days |
Plan your site schedule from the total figure, not just production. A reliable supplier gives you a written production plan with milestone dates after the deposit.
