Anodized Aluminum Sheet

Anodizing grows a layer of oxide out of the aluminum itself, so the colour sits inside the metal rather than on top of it. That is why an anodized panel keeps its colour where a painted one chips, and why the film thickness is part of the specification.

Colour that is part of the surface. The anodic layer is converted from the substrate, so it does not peel or flake the way a coating can when an edge is damaged.
Film thickness quoted, not implied. 8–12 µm for interior work, 15–25 µm where the panel is outdoors or handled. The number decides colour fastness and cost.
Matte, brushed or mirror before anodizing. The mechanical finish is applied first and the anodizing preserves it, so the look is decided before the anodizing line, not after.
Sheets and coil. Cut sheets for panels, coil for continuous lines, with the width and the coil weight agreed against the line rather than the catalogue.

Anodized aluminum sheet samples in gold, bronze and natural

The Forms We Supply

Four routes cover most of what we quote. Each is a different mill or process route, so the size window and the lead time differ even where the grade looks similar.

Natural and champagne

The two most specified anodic colours, matched across a batch because the alloy and the base finish are controlled together.

Facades, ceilings, appliance panels

Bronze range

Light and dark bronze anodized sheet for architectural work where the colour has to sit against stone, timber or glass.

Cladding, window trims, interiors

Colour anodized

Gold, red, blue, black and custom colours, with a deeper film where the panel is outdoors or handled.

Signage, retail fit-out, feature panels

Anodized coil

Coil anodized for continuous lines, in widths and coil weights agreed against the line rather than the catalogue.

Roll forming, continuous lamination

Size Range and Standard

Anodized sheet is quoted by alloy, thickness, finish and film thickness. Colour matching is done against a physical sample, because a screen cannot show an anodic colour faithfully.

Parameter	Range	What decides it
Thickness	0.3 – 6.0 mm	Thin sheet for panels and trim, thicker for structural and fabricated parts.
Width	Standard 1000, 1220, 1250, 1500 mm; cut to width	Coil lines take a fixed width; cut sheets follow the panel size.
Length	Standard 2000, 2440, 2500, 3000 mm; cut to size	Cut-to-size blanks reduce offcut on a project with a repeating panel.
Alloys	1060, 1100, 3003, 5005, 5052, 6061	5005 and 5052 anodize to the most consistent colour; 3003 is the workhorse.
Film thickness	8 – 12 µm standard; 15 – 25 µm for exterior	Thicker film gives better colour fastness outdoors, at a higher cost.
Colours	Natural, champagne, light and dark bronze, gold, black, plus colours	Deep colours need a tighter alloy and a better base finish.

Products' Properties and Advantages

Anodized sheet is judged on four things, and only one of them is visible in a photograph.

Abrasion resistance

The oxide layer is harder than the aluminum beneath it, so a correctly anodized panel resists handling marks far better than bare sheet.

Colour consistency across a batch

The alloy and the base finish decide whether two sheets match. That is why colour is approved on a sample from the production alloy, not from a colour card.

Corrosion protection

The sealed anodic layer limits further oxidation, which is what makes anodized sheet usable on facades and in wet interiors.

Light fastness

Film thickness and sealing decide whether a colour holds outdoors. Interior and exterior specifications are not interchangeable.

How We Help Customers

Anodized sheet orders are decided by alloy, film thickness and colour sample. We confirm all three before quoting, because each of them changes the price.

Choose the alloy for the colour

5005 and 5052 give the most consistent anodic colour; 3003 is the general-purpose choice.

Specify the film thickness

8–12 µm for interior, 15–25 µm for exterior and handling-heavy work. The number goes on the order.

Agree the base finish

Matte, brushed or mirror before anodizing; the anodizing preserves what the mechanical finish left.

Approve a physical colour sample

Screens do not show anodic colour. Approval is against a sample made on the production alloy.

Real Applications

Anodized sheet is used wherever a metal surface has to look the same in year five as it did on installation day.

Architectural cladding and ceilings

Panels and cassettes where the colour and the flatness are the visible specification.

Appliance and electronics housings

Covers and panels that need a hard, non-conductive, scratch-resistant surface.

Interior fit-out and furniture

Trim, splashbacks and feature panels in bronze, champagne or black, matched across a batch.

Signage and display

Substrates that hold a colour outdoors without a painted film that can chip at the edge.
