Material Guidelines
Proper material selection, surface condition, and packaging ensure optimal coating results. Follow these guidelines when preparing materials for finishing.
Acceptable Substrates
We coat aluminum and selected steel components. Here are the most common alloys we process.
| Alloy | Typical Use | Notes |
|---|---|---|
| 6063-T5/T6 | Extrusions | Most common architectural alloy |
| 6061-T6 | Structural components | Higher strength applications |
| 3003-H14 | Sheet/panels | Good formability |
| 5005-H34 | Sheet/panels | Excellent anodizing match |
| 5052-H32 | Sheet/panels | Marine applications |
Note: Contact us before shipping non-aluminum substrates or unusual alloys. We may need to adjust our pretreatment process for optimal results.
Surface Condition Requirements
Materials should arrive clean and free of contaminants for best results.
Ideal Condition
- Clean mill finish, minimal oxidation
- Free of oils and lubricants
- No visible scratches or defects
- Stored indoors, protected from elements
What to Avoid
- Mill finish oxidation
- Fingerprints/handling marks
- Cutting fluids/lubricants
- Marker/ink
Contaminants to Avoid
Mill finish oxidation
Heavy oxide buildup from extended storage
Fingerprints/handling marks
Oils from bare-hand handling
Cutting fluids/lubricants
Residue from fabrication processes
Marker/ink
Part identification marks in coating areas
Tape residue
Adhesive from protective or masking tape
Weld spatter
Spatter in areas to be coated
Deep scratches
Mechanical damage beyond pretreatment repair
Pitting/corrosion
Surface degradation from improper storage
Packaging for Shipment
Proper packaging prevents damage during transit and ensures parts arrive in optimal condition.
Interleaving
Place paper or foam between parts to prevent surface-to-surface contact.
Foam Protection
Use foam corners or end caps on extrusion ends to prevent damage.
Secure Bundling
Bundle extrusions securely with strapping and cardboard edge protectors.
Weather Protection
Wrap bundles in plastic to protect from moisture during transit.
Important Notes
- Use gloves when handling parts to avoid fingerprints on surfaces to be coated.
- Mark identification numbers in areas that will not be coated (back side, cut ends).
- Include packing list with part numbers and quantities for verification.
- Photograph material condition before shipping for your records.
