Product Details

In the metal industry, “aluminum steel plate” is often used in search queries to refer to aluminum sheet or aluminum plate products. One of the most important selection factors for aluminum sheets is the surface finish, which directly affects appearance, corrosion resistance, and application performance.

Teda Ganghua supplies aluminum plates in multiple surface finishes for construction, industrial fabrication, and decorative applications.

1. Mill Finish (Raw Surface)

Mill finish is the most basic aluminum surface condition, directly produced after rolling.

Characteristics:

No additional surface treatment
Natural aluminum metallic appearance
Slight rolling marks may exist
Lowest processing cost

Applications:

Industrial structures
Fabrication parts
Internal mechanical components

👉 Suitable where appearance is not critical.

2. Brushed Finish (Hairline Aluminum)

Brushed aluminum is produced by mechanical abrasion, creating a linear grain pattern.

Characteristics:

Fine directional texture
Modern metallic appearance
Better scratch masking than mill finish

Applications:

Elevator panels
Interior decoration
Appliance housings
Architectural panels

👉 Widely used for decorative and commercial surfaces.

3. Polished Finish (Mirror Aluminum)

Polished aluminum is mechanically or chemically treated to achieve a high-gloss reflective surface.

Characteristics:

High reflectivity (mirror effect)
Smooth and bright surface
More sensitive to scratches

Applications:

Decorative panels
Lighting reflectors
High-end interior design
Signage applications

4. Anodized Finish

Anodizing is an electrochemical process that forms a protective oxide layer on the aluminum surface.

Characteristics:

High corrosion resistance
Hard and wear-resistant surface
Available in natural silver, black, bronze, gold, etc.
Long service life

Applications:

Curtain walls
Architectural facades
Electronic housings
Industrial equipment panels

👉 One of the most durable surface treatments.

5. Painted / Coated Finish

Painted aluminum sheets are coated with organic paint or PVDF coatings.

Characteristics:

Wide color selection
Strong decorative effect
Good weather resistance (depending on coating type)

Applications:

Building facades
Roofing systems
Signage and advertising panels
Exterior decoration

6. Embossed Aluminum Sheet

Embossed sheets have patterned surfaces such as diamond, stucco, or ripple textures.

Characteristics:

Anti-slip performance
Increased rigidity
Decorative and functional texture

Applications:

Flooring panels
Refrigeration equipment
Transportation platforms
Industrial anti-slip surfaces

7. Perforated Aluminum Sheet

Perforated sheets are processed with uniform holes or custom patterns.

Characteristics:

Lightweight structure
Ventilation and airflow function
Decorative appearance

Applications:

Acoustic panels
Ventilation systems
Facade decoration
Filter and shielding systems
