2mm 4mm Color Coated Brushed Aluminum Coils
2mm and 4mm color coated brushed aluminum coils combine the crisp, directional texture of a brushed finish with a durable, decorative color coating-delivered in coil form for efficient fabrication. This product is designed for customers who need consistent appearance across large surfaces, strong corrosion resistance, and reliable formability for bending, roll forming, and panel processing.
Brushed color coated coils are widely selected for architectural cladding, interior decoration, signage, transport trim, and premium consumer-facing metalwork. The brushed grain adds depth and "movement" under light, while the coating protects the surface and stabilizes the color in service.
What "Color Coated + Brushed" Means in Practice
A brushed aluminum surface is mechanically grained to produce a linear satin texture. After brushing, a coating system-commonly PE (polyester), PVDF, or PU-is applied and cured to create a uniform, protective color layer while preserving the brushed character.
outcomes customers value:
- High-end metallic look with controlled gloss and visible grain
- Improved stain and fingerprint resistance compared with bare brushed aluminum (depending on coating selection)
- Color consistency between batches and across large façade areas
- Corrosion protection that supports long service life in outdoor or humid environments
Typical Alloy Options and Chemical Composition
Color coated brushed aluminum coils are commonly produced from 1xxx, 3xxx, and 5xxx series alloys. Selection depends on the balance needed between formability, strength, and corrosion resistance.
Chemical Composition (Typical Reference Values, wt.%)
| Alloy | Si | Fe | Cu | Mn | Mg | Zn | Ti | Al |
|---|---|---|---|---|---|---|---|---|
| 1050 | ≤0.25 | ≤0.40 | ≤0.05 | ≤0.05 | ≤0.05 | ≤0.05 | ≤0.03 | Balance |
| 1060 | ≤0.25 | ≤0.35 | ≤0.05 | ≤0.03 | ≤0.03 | ≤0.05 | ≤0.03 | Balance |
| 3003 | ≤0.60 | ≤0.70 | 0.05–0.20 | 1.0–1.5 | ≤0.10 | ≤0.10 | - | Balance |
| 5052 | ≤0.25 | ≤0.40 | ≤0.10 | ≤0.10 | 2.2–2.8 | ≤0.10 | - | Balance |
Selection guidance (fast read):
1050/1060 emphasizes smooth forming and clean brushing; 3003 adds strength and excellent workability; 5052 is preferred for stronger, more corrosion-resistant parts (coastal, transport, equipment housings).

Coating System Options (Performance-Focused)
Coating choice drives weatherability, chemical resistance, and long-term color stability. For exterior architecture, coating selection is often more important than alloy choice.
Coating Build (Typical)
| Layer | Typical Thickness |
|---|---|
| Top coat | 15–25 μm (PVDF often 25 μm) |
| Primer | 5–10 μm |
| Back coat | 5–10 μm (service side dependent) |
| Total (single-side) | Commonly 25–35 μm |
| Total (double-side) | Commonly 35–50 μm |
Coating Type Comparison
| Coating Type | Strengths | Best-fit Applications |
|---|---|---|
| PE (Polyester) | Cost-effective, good color range, solid indoor/outdoor performance | Interior panels, signage, general cladding |
| PVDF | Excellent UV resistance, chalking control, long outdoor life | Exterior façades, canopies, high-sun regions |
| PU / SMP (where available) | Improved scratch resistance, robust film properties | Transport trim, equipment panels, high-touch areas |
Performance Features Customers Notice
Durable aesthetics with "depth"
The brushed grain breaks up reflections and reduces visual waviness. Under different lighting angles, the surface shows a subtle gradient-ideal for premium storefronts, elevator skins, and display panels.
Strong process compatibility
Coils are designed for slitting, shearing, bending, roll forming, and composite panel lamination. In 2mm thickness, the product is common for decorative sheets and formed trims. In 4mm, it is chosen when customers want stiffer panels, reduced oil-canning, and better dent resistance.
Corrosion resistance built into the system
The coating isolates the aluminum surface from moisture and contaminants. When paired with appropriate alloy selection (notably 3xxx or 5xxx) and correct edge sealing in installation, the system performs reliably in urban and industrial atmospheres.
Controlled surface protection during fabrication
Optional protective film reduces handling scratches and shop-floor marking-especially valuable when coils are processed into visible, customer-facing panels.
Recommended Applications
Architectural exteriors and façade components
Color coated brushed coils are frequently processed into wall cladding, soffits, fascia, column covers, and curtain wall decorative elements. PVDF-coated variants are favored where sun exposure and long-term color stability are critical.
Interior decoration and premium finishes
The brushed look fits lobbies, elevator door skins, ceiling systems, partitions, and retail interiors. Compared with mirror-like finishes, brushed surfaces hide small scuffs better and maintain a consistent appearance.
Signage, branding, and display systems
Excellent for channel letters, sign backers, branded wall panels, and exhibition structures. The combination of color control and texture gives signage a more "engineered" feel than flat painted sheet.
Transportation and equipment trim
Used for bus and rail interior panels, decorative strips, tool housings, appliance cladding, and other applications requiring a balance of appearance and durability. PU/SMP-style systems (where specified) help resist abrasion in high-contact environments.
Quick Selection Guide (2mm vs 4mm)
| Requirement | Prefer 2mm | Prefer 4mm |
|---|---|---|
| Tight bending / easier forming | Strong fit | Possible, but check bend radius and tooling |
| Lightweight parts | Strong fit | Heavier; used when stiffness matters |
| Large panels needing rigidity | Limited | Strong fit |
| Dent resistance | Moderate | Better |
| Decorative trims, signage | Strong fit | Used for rigid signboards and structural decorative panels |
Processing Notes for Better Finished Results
| Topic | Practical Recommendation |
|---|---|
| Brushing direction | Align grain direction across parts to avoid shade mismatch |
| Bending | Use adequate inside bend radius; protect coating with clean tooling |
| Cutting | Sharp blades reduce edge burr and coating micro-cracks |
| Film removal | Remove after installation or final clean; avoid long UV exposure if film is not UV-rated |
| Storage | Keep dry, ventilated; avoid condensation and stacked water ingress |
