Export Supply Checklist
Before importing, confirm resin system, color, gloss, film build, cure window, test standard, certificates, packing, quantity and destination port. We return one written quotation covering MOQ, sample quantity, production window, QC documents and freight options.
- Stock RAL colors: typically 25-100 kg per color
- Custom colors: often 100 kg or more per color
- Samples: usually 1-5 kg per color
- Stock production: typically 7 working days after approval
- Custom production: usually 7-15 working days after approval
- QC and packing: normally 1-3 working days
- Sea freight from Xiamen/Fuzhou: often 25-45 days to Europe or North America
For facade programs, also record gloss retention, weathering test target, extrusion alloy and fabrication sequence. Request batch COA, SDS, and RoHS/REACH declarations where relevant; WRAS, ACS or other approvals depend on the selected system.
Powder Coating for Aluminum Profiles and Architecture
Architectural aluminum is a system, not just a color: the right pretreatment, weathering resins and film build keep facades, windows and curtain walls looking right for decades.
Recommended Coating Systems
- Super-durable polyester for exterior facades
- PVDF systems for landmark projects
- Chrome-free conversion pretreatment
Key Performance Properties
- UV and gloss retention
- Chalk and fade resistance
- Excellent adhesion to aluminum
- Consistent color along long profiles
Typical Specifications
- Film thickness: 60–100 µm (typical)
- Gloss: 30–40 typical for architecture
- Cure: 180–200°C
- Weathering tests per project specification
Application Notes
- Use chrome-free conversion coating before coating
- Measure film at ends and middle of profiles
- Plan masking for mating surfaces
Frequently Asked Questions
Polyester or PVDF for my facade?
Super-durable polyester suits most projects; PVDF is chosen when the spec demands maximum weather resistance.
How do you control color on 6-meter profiles?
We measure at multiple points against an approved master sample.
Buyer Decision Snapshot
For curtain walls, agree gloss retention, film thickness and warranty testing before color approval.
