What are 1060 and 3003 Color Coated Aluminium Sheets?
Both 1060 and 3003 are common Aluminium alloys:
- 1060 Aluminium Sheet: High-purity aluminium (≥99.6%) characterized by excellent electrical and thermal conductivity plus intrinsic corrosion resistance. It is relatively soft and has good workability.
- 3003 Aluminium Sheet: An alloy consisting of about 1% manganese, enhancing strength while maintaining good corrosion resistance and formability.
When coated with organic coatings (PVDF, Polyester, Fluorocarbon, etc.), these sheets gain better surface protection, aesthetic value, increased durability, and sometimes additional functionalities like anti-corrosion or anti-UV resistance.
Functions of 1060 & 3003 Color Coated Aluminium Sheet

Implementation Standards
| Standard | Description | Alloy Coverage |
|---|---|---|
| GB/T3880-2006 | Aluminium and aluminium alloys | Both 1060 & 3003 |
| ASTM B209 | Aluminium plate and sheet standard | Widely referenced internationally |
| JIS H4100 | Aluminium and aluminum alloy sheets | Common in Japan region |
Typical Applications
| Application Area | Details |
|---|---|
| Building & Construction | Exterior wall cladding, façade panels, suspended ceilings |
| HVAC and Ventilation | Air ducts, ventilation hoods and grills |
| Transportation Sector | Interior and exterior finishes on buses, trucks, and trailers |
| Signage & Advertising | Outdoor advertising panels needing long-lived colors and abrasion resistance |
| Household Appliances | Refrigerator housings, decorative appliance panels |
| Electrical Industry | Reflectors, busbars (especially using 1060 alloy for conductivity) |
Surface Treatment and Coating Types
After precise mechanical preparation, Aluminium sheets undergo coating processes such as:
| Coating Type | Characteristics | Common Usage |
|---|---|---|
| PVDF (Polyvinylidene fluoride) | Outstanding colour retention, UV resistance and durability | Architectural cladding |
| Polyester (PE) | Cost-effective, available in many colours | Indoor and outdoor decorations |
| Silicon Modified Polyester (SMP) | Better weather resistance than common PE | Building panels |
| Fluorocarbon Coating | Superior ageing resistance, anti-corrosion | High-end exterior panels |
Thickness of paint layers and cure times relate directly to durability and appearance quality, generally ranging
from 15µm (primer) + 18-25µm (topcoat).
The 1060 and 3003 color coated aluminium sheets merge aluminium’s inherent strengths — light weight, corrosion resistance, electrical and thermal conduction — with the benefits inherent in quality color coating: durability, aesthetics, and weather resistance.
Their chemical structure, mechanical temper options, and conformance to national/international standards make them fit for versatile and enduring applications ranging from construction and decoration to HVAC and transport industries.
Consider these materials when your projects demand an optimal balance between mechanical strength, surface quality, and long-term environmental performance.
