3003 aluminum plate is a practical choice for architectural facade panels where good formability, corrosion resistance and moderate strength are more important than maximum structural strength.
Alloy 3003 is a manganese-alloyed aluminum material with better strength than 1100 aluminum while maintaining excellent forming performance and corrosion resistance. It is widely selected by curtain wall fabricators and building material manufacturers that require stable flatness, consistent surface quality and reliable performance after bending, punching or coating.
As a manganese-alloyed aluminum grade, 3003 is well suited to fabrication processes such as bending, forming and panel fabrication. Haomei Aluminum supplies 3003 H14 and H24 aluminum sheet for curtain wall applications, with customizable thickness, width, surface finish, coating and panel fabrication options.
Why Choose 3003 Aluminum for Curtain Wall Panels?
- Good formability: Suitable for bending, folding, rolling, stamping and profiling.
- Higher strength than 1100 aluminum: The manganese content improves strength without making the material difficult to process.
- Reliable corrosion resistance: Appropriate for exterior architectural applications after proper pretreatment and coating.
- Good surface quality: Suitable for PVDF coating, powder coating, anodizing and other decorative finishes.
- Lightweight material: Helps reduce dead load in curtain wall and cladding systems.
- Consistent fabrication performance: Suitable for aluminum veneer, perforated panels, composite panel skins and honeycomb panel face sheets.
For projects requiring a decorative, durable and easy-to-fabricate metal substrate, 3003 is one of the most commonly used aluminum alloys in architectural sheet applications.

3003 H14 vs H24 Aluminum Sheet for Curtain Wall
Haomei commonly supplies 3003 aluminum sheet in H14 and H24 tempers for architectural applications. Temper selection should be related to panel geometry, forming requirements and the final installation design.
3003 H14
Strain-hardened aluminum sheet that offers a firmer material condition for applications where a balance of strength and workability is required.
It can be considered for formed architectural panels where the fabrication process and required bend geometry are compatible with the H14 temper.
3003 H24
Strain-hardened and partially annealed aluminum sheet offering a balance between strength and forming performance.
It can be considered when fabrication requires a different balance of workability and mechanical performance than H14. It is often selected for aluminum curtain wall panels and other formed façade applications.
3003 O
Soft, annealed condition that may be considered for applications requiring extensive forming.
Surface Finishes for 3003 Curtain Wall Aluminum Plate
PVDF Coated 3003 Aluminum Sheet
PVDF coating can be selected for architectural projects requiring long-term exterior color and weather resistance.
PE Coated 3003 Aluminum Sheet

Mill Finish
Mill-finish 3003 sheet can be supplied for customers who plan to perform subsequent processing or apply their own finishing system.
Brushed Finish
Brushed aluminum may be considered for selected decorative architectural applications where a directional metallic appearance is required.
Anodized Finish
Anodized finish can be considered for suitable architectural components where the required appearance and environmental conditions are compatible with the specified anodizing system.
Protective Film
Protective film can be specified to help reduce surface scratching during fabrication, handling, storage and transportation.

3003 Aluminum Curtain Wall Panel Applications
3003 aluminum sheet is used in architectural applications where the material needs to be formed into panels while maintaining a consistent surface appearance.
Curtain Wall Panels
Can be fabricated into exterior aluminum panels as part of a properly engineered curtain wall system.
Aluminum Veneer
The alloy's formability makes it suitable for fabricated aluminum veneer and decorative facade components.
Aluminum Composite Panels
3003 aluminum can be used as sheet material in certain composite panel constructions, depending on the panel design.
Aluminum Honeycomb Panels
3003 sheet may be considered as a face-sheet material for selected honeycomb panel constructions where the required characteristics are met.

3003 vs Other Aluminum Alloys for Curtain Wall Panels
There is no single aluminum alloy that is best for every facade project. Material selection should consider strength, forming, corrosion exposure, finishing requirements and panel construction.
| Alloy | General Characteristic | Typical Consideration |
| 3003 | Good formability, corrosion resistance and moderate strength | General architectural panels and formed cladding |
| 3004 | Higher strength than 3003 with good formability | Applications requiring somewhat higher strength |
| 5052 | Higher strength and strong corrosion resistance | More demanding mechanical or environmental requirements |
| 1100 | Very high formability and excellent corrosion resistance | Decorative components where high strength is not the priority |

FAQ – 3003 Aluminum Sheet for Curtain Wall Panels
Is 3003 aluminum suitable for curtain wall panels?
Yes. 3003 aluminum sheet is widely used for curtain wall panels, aluminum veneers, decorative cladding, aluminum composite panels and honeycomb panels. It provides good corrosion resistance, formability and moderate strength for architectural processing.
What thickness of 3003 aluminum plate is used for curtain walls?
Common thicknesses include 1.5 mm, 2.0 mm, 2.5 mm and 3.0 mm. The correct thickness depends on panel dimensions, stiffener design, wind-load requirements, panel shape and installation system. Larger or shaped panels may require a different thickness or reinforcement design.
Which is better for aluminum facade panels, 3003 H14 or H24?
Neither temper is universally better. 3003 H14 is widely used for standard flat or moderately formed panels, while H24 may be preferred where a different balance of strength and forming capability is required. The selection should be based on the panel drawing and fabrication process.
Can 3003 curtain wall aluminum plate be PVDF coated?
Yes. 3003 aluminum sheet is a common substrate for PVDF-coated aluminum panels. PVDF coating is especially suitable for exterior applications requiring strong UV resistance, weather durability and color retention.
Can Haomei Aluminum supply custom sizes?
Yes. Haomei can supply coil, standard sheet and cut-to-length material according to the required thickness, width and length. Please contact us with your size range, dimensions and quantity for a customized quotation.
Is 3003 stronger than 1100 aluminum?
3003 generally provides higher strength than commercially pure 1100-series aluminum while retaining good formability. Actual mechanical properties depend on temper and product specifications. For a direct comparison, you can also review 1100 aluminum sheet specifications.
What is the difference between 3003 and 5052 aluminum for curtain wall panels?
3003 is generally favored when formability and moderate strength are important. 5052 aluminum sheet offers higher strength and is often considered where more demanding mechanical or environmental requirements apply. The final selection should be based on the complete curtain wall design, forming requirements and service environment.
