Pre-anodised Aluminium Sheet

aluminium sheet

Architects are often asked to create beautiful projects, made from high quality materials that deliver a consistent look and finish. These products must be durable, able to be formed into a variety of shapes for different cladding, roofing, ceiling, wall or accent elements and be strong, yet lightweight to help reduce construction costs. At thyssenkrupp Materials UK, we got it all covered. We have partnered with one of the world’s leading suppliers of pre-anodised material and are now offering the only available on the UK construction and architectural market - continuous anodising on flat rolled aluminium products, whilst still in coil form, alongside a convenient de-coiling to size service.


Aluminium alloys used 1000, 3000, 5000 and 6000-series

Coil Width1000mm - 2000mm
Metal Thickness0.3mm - 3.5mm
Anodic Layer ThicknessLess than 1μm - 25μm
Coil WeightMax 6000kg to 10000kg per specification

Construction and Architecture

Architectural anodising is used to produce an architectural finish for permanent, exterior applications where both appearance and long life are important. Our pre-anodised aluminium sheets are classed as high quality, added-value product within the construction and architecture market in the UK and can be used for:

  • All types of solid panel building façade

  • Interior panel walls and ceilings

  • Composite, honeycomb and insulated panels

  • Rainscreen cladding

  • Standing seam roofs

  • Interior decorative elements

  • Complex structures such as perforated panels or expanded mesh


Because anodised colours are below the surface of the aluminium, they won’t fade, chip, flake or peel, which makes them ideal for use on cladding projects. With the UK government bringing an end to unsafe cladding with multi-billion pound intervention and funding the work to urgently replace fire-risk cladding by introducing a developer levy to recoup cost, our A1 Class fire rated aluminium sheets are completely non-combustible. This means that they can be used in facades of all heights (including those over 18m), without further testing (provided that all the other materials within the wall are also A2 classified or better). Therefore, our pre-anodised aluminium sheets the perfect solution for replacing non-compliant ACM, HPL and timber cladding.

De-coiling to size

coil line

We have recently invested in a new cut-to-length line at our Vetchberry site. The line is dedicated to the processing of both coated and un-coated aluminium coil in to sheet from our extensive stock range and customer specific products.  With a maximum width of 1500mm and lengths up to and including 6000mm long, this allows us to support the further developing demand within Architectural applications.  A precision leveller, automatic stacking system and in-line vinyl coating applicator allows us to tailor a service to our customers individual needs.

Colours & Finishes

Our pre-anodised aluminium sheets have exceptional dimensional capacity, offering a wide range of different gloss levels, textures and colours. In addition, these colours can be applied to finishes that are brushed, embossed, bright or matte. Our process of continuous anodising of aluminium allows an unmatched level of consistency, assuring that the colours and finishes look the same throughout all of the coils produced.

The anodic film layer can be coloured through various processes. All colouring processes retain the genuine metallic sheen of the metal. Electrolytic colouring, where metallic salts are integrated into the anodic film layer, produces the colour optically and therefore, it will not fade even with exposure to sunlight over many years. Using this process, finishes similar to bronze and copper can be achieved. Auto-colouration is where the colour is achieved through natural anodising of certain specific aluminium alloys. Typically, this will give grey colours similar to zinc.
