High-Performance Coil & Strip Solutions for Architectural and Industrial Panels
Aluminum strip panel using 5005 and 5052 alloys delivers excellent corrosion resistance, medium-to-high strength, and superior surface quality for architectural façades, curtain walls, interior cladding, signage, and industrial panel systems. These alloys offer stable anodizing performance, good formability, and consistent flatness, making them ideal for coil-coated, anodized, or PVDF-painted panel applications that demand both aesthetics and durability.
Aluminum strip panels made from 5005 and 5052 alloys are widely used as base materials for composite panels, honeycomb panels, and solid sheet façades. Supplied in coil or precision-cut strip form, they offer:
- Stable mechanical properties across coil length
- Excellent corrosion resistance in outdoor and marine environments
- Consistent surface for anodizing or high-end coating systems
5005 is favored for architectural anodized finishes due to its color consistency, while 5052 is chosen where higher strength and better seawater resistance are required.

| Deep forming, tight radii | 5005-O / 5052-O | Maximum ductility and low cracking risk |
| Coil coating + moderate forming | 5005-H14 / H16 | Good balance of strength and bendability |
| High rigidity, thin gauge | 5005-H18 or 5052-H34 | Higher yield strength for stiffness |
| Structural panels in marine / transport | 5052-H32 / H34 | Superior corrosion resistance and strength |
| Anodized architectural sheets | 5005-H14 / H16, special anodizing-quality coils | Uniform color and gloss across façade elements |
