The 0.5mm thickness 1100 / 3003 color coated aluminum sheet is a lightweight, decorative, and corrosion‑resistant material widely used in building facades, roofing, ceilings, advertisement panels, interior decoration, and appliance shells. This product combines the base properties of 1100 or 3003 aluminum alloys with durable organic coatings, offering both structural reliability and high visual impact.
Color coated aluminum sheet at 0.5mm thickness is designed for applications where:
- Precise thin‑gauge material is needed
- Color consistency and flatness are crucial
- Corrosion resistance and formability must be balanced with cost
1100 alloy emphasizes purity and excellent corrosion resistance, while 3003 alloy provides higher strength and better formability through manganese alloying. Both alloys are ideal substrates for coil coating processes.
