Aluminium sheet finishes are an important consideration for any project involving fabrication, signage, interiors or decorative work. From brushed and anodised to patterned checker plate, each aluminium finish brings its own benefits in terms of appearance, durability and function.
This guide from Metal Offcuts explains the main aluminium sheet finishes and how to choose the right option for your project.
Types of Aluminium Sheet Finishes
1. Natural Aluminium (Mill Finish)
A smooth, untreated surface straight from the mill.
- Applications: General fabrication, painting, printing and signs
- Finish look: Slightly reflective light grey, may show marks or scuffs from handling

Among the most versatile aluminium sheet finishes, mill finish offers a clean base for further processing or direct application.
2. Brushed Aluminium
A satin finish created with abrasive brushing.
- Applications: Decorative panels, signage, splashbacks
- Finish look: Uniform grain with a modern industrial appearance

Brushed aluminium is one of the most popular aluminium sheet finishes for decorative uses and commercial interiors.
3. Polished Aluminium (Mirror Finish)
Highly reflective and smooth — similar to a mirror.
- Applications: Decorative trim, signage, visual displays
- Finish look: Chrome-like reflective surface

Mirror-polished aluminium sheet finishes are perfect for creating high-impact visual effects in retail and exhibition design.
4. Checker Plate Aluminium Sheet Finish
Raised pattern for grip and strength.
- Applications: Flooring, ramps, vehicle mods, stairs
- Finish look: Textured surface with a raised five-bar pattern

As one of the more functional aluminium sheet finishes, checker plate combines durability with slip resistance.
5. Stucco Aluminium Sheet Finish
Embossed with a dimpled texture for light diffusion and stiffness.
- Applications: Insulation cladding, linings, panels
- Finish look: Pebbled or orange-peel surface
Link: Stucco Embossed Aluminium Sheet
Stucco embossing is a textured aluminium sheet finish that enhances rigidity and hides handling marks.
6. Anodised Aluminium
Electrochemically treated for colour, corrosion resistance and a clean matte look.
- Applications: Signs, display panels, architectural use
- Finish look: Satin to matte silver, sometimes colour tinted

Anodised aluminium sheet finishes offer corrosion resistance and a premium architectural look with long-lasting colour options.
