What Are Anodized Aluminium Composite Panels and How Are They Made

28 Oct What Are Anodized Aluminium Composite Panels and How Are They Made

You see an anodized aluminium composite panel when you want a strong and modern building surface. Anodized aluminum composite panels have two thin sheets of anodized aluminium. These sheets are joined to a core. This material is different from regular panels. The anodized layer gives more protection and a shiny finish. When you pick anodized aluminium composite panel, you get a surface that does not scratch or fade easily. The anodized surface lasts longer and keeps its color bright. People all over the world use anodized aluminium composite panel for big and small jobs.

• The global market for anodized aluminum composite panels was about USD 7.2 billion in 2024.

• By 2032, experts think the market will grow to USD 11.4 billion.

If you want a surface that looks nice and stays strong, anodized aluminium composite panel gives you both. Architects and builders use acp because it is tough, easy to clean, and looks modern. Anodized aluminium composite panel helps your project stand out. Acp is a smart choice for any design. You see anodized aluminum composite panels in many places because acp lasts a long time. Pick anodized aluminium for any job where you want something pretty and strong. The anodized finish on every acp keeps your building looking new.

Key Takeaways

• Anodized aluminum composite panels are strong and look modern. They work well for outside and inside uses. The anodized surface makes them last a long time. It also helps stop scratches and damage from the sun. This keeps the panels looking good for years. These panels are simple to clean and do not need much care. This saves you time and work. Anodized aluminum composite panels come in many colors and finishes. This gives you lots of design choices for any project. If you pick panels with a fire-resistant core, they are safer. This makes them good for places where fires might happen.

Anodized Aluminium Composite Panel Structure

Layer Composition

Anodized aluminum composite panels have a clever design. Each acp panel has three layers. There are two thin anodized aluminium sheets on the outside. These sheets cover a strong core in the middle. The layers make the surface tough and smooth. The outer sheets protect the core and look modern. The core gives strength and keeps the panel light. You can use acp for many jobs. The layers make it easy to move and install.

Here is a table that shows the usual thickness and layer setup for different uses:

Application Type	Total Thickness	Skin Thickness
Exterior Wall Decoration	≥ 4mm	≥ 0.2mm
Indoor Panels	3mm	~0.2mm
Building Curtain Wall	> 4mm	≥ 0.5mm

You can also find acp sheets in these common thicknesses:

Panel Type	Common Thicknesses
ACP Sheets	3mm, 4mm, 6mm

Core Materials

The core inside anodized aluminium composite panels is important. It changes how the acp panel works. You can pick from different core materials. Some acp panels have a plastic core. Others have a mineral-filled fire-resistant core. The right core helps you follow safety rules.

• If you pick a mineral-filled fire-resistant core, you get great fire protection. This is good for tall buildings and places where safety is key.

• You can choose aluminum composite panels with a fire retardant core. These acp panels can reach FR B1 grade or FR A2 grade. This means you get better fire resistance.

The core material also changes the strength of the acp panel. You get a panel that is strong but not heavy. The core keeps the acp panel flat and helps it last longer. When you use aluminium composite panels with the right core, your building is safer and stronger.

Anodized Surface

The anodized surface makes anodized aluminium composite panels special. Each acp panel has a special layer on the outside. This layer is made by the anodizing process. The anodized surface is not just a coating. It is a hard, oxide layer that sticks to the aluminium. You get a surface that is tough and does not scratch easily.

Here is a table that shows how the anodized surface helps you:

Feature	Benefit
Exceptional Durability	The hard, oxide layer gives better scratch and abrasion resistance than raw aluminum.
UV Stability	The color in anodized aluminum stays bright and does not fade from UV rays, so it is good for outdoor use.

You get more good things from the anodized surface:

• Anodizing makes the surface harder because the oxide layer is like ceramic.

• Anodized aluminium is better at stopping nicks and scratches than untreated aluminum.

• The anodized surface helps stop wear and keeps your acp panel looking new.

When you pick anodized aluminium composite panels, you get a surface that stays bright and strong. The anodized finish protects your acp panel from weather and sunlight. You do not have to worry about fading or damage. The surface keeps your building looking fresh for years. You can trust the anodized surface to give you great results for any project.

Manufacturing Process

When you see anodized aluminum composite panels, they are made with care. Each acp goes through many steps. These steps make the panel strong and nice-looking. The process helps the panel last a long time. You will learn about pre-treatment, anodizing, and making the final panel.

Pre-Treatment

Pre-treatment is the first step. It gets the aluminum sheets ready for anodizing. Clean sheets help the anodized layer stick well. Clean sheets also last longer. You need to remove dirt, oil, and old layers from the aluminum. Pre-treatment uses chemicals and machines.

Here is a table that shows the main ways to clean the sheets:

Method Type	Description
Chemical	Cleans off old layers and dirt with pickling. This makes the surface look matte.
E0 Pickling	Uses gentle pickling to get the surface ready. The surface looks a little matte.
E6 Pickling	Uses a special bath to make the surface even and matte.
Mechanical	Uses nano matte blasting to make the surface smooth and even.

You follow these steps to clean the aluminum:

1. Degreasing: Take off oil and sticky stuff from the sheets.

2. Etching: Make the surface smooth and fix small problems with a special solution.

3. Desmutting: Clean off black stuff left after etching.

You use chemicals like sulfuric acid, phosphoric acid, and chromic acid. Sulfuric acid is used in sulfuric acid anodizing. Phosphoric acid is used in phosphoric acid anodizing. These chemicals help make the surface clean and even for the next step.

Anodizing Process

Anodizing is the most important step. It makes the aluminum strong and protects it. You use electricity and acid to make a hard layer on the aluminum. This layer keeps the panel safe from rust and damage.

You put the clean aluminum sheets in an acid bath. You use electricity in the bath. This makes the anodized layer. The thickness of the layer depends on the type of anodizing. Here is a table that shows how thick each type is:

Anodizing Type	Thickness Range
Chromic Anodizing	0.02 to 0.1 mils (0.5 to 2.5 microns)
Sulfuric Anodizing	Up to 1 mil (25 microns)
Hard Anodizing	0.5 to 4 mils

Anodizing gives you many good things:

Advantages of Anodizing	Description
Corrosion Resistance	Anodizing helps stop rust and damage from water.
Mechanical Properties	The hard layer makes the panel tough and bendy.
Surface Properties	Paint sticks better and the layer protects even more.

The surface does not scratch or fade easily. The color stays bright and the surface stays smooth. This step makes anodized aluminum composite panels better than regular acp.

Fabrication Stages

After anodizing, you finish making the panel. You cut, groove, bend, and put the acp together. Each step helps you get the right shape and size.

Here is the order for making the panel:

• Cutting: Cut the sheets and core to the size you need.

• Grooving: Make grooves so you can bend the panel without breaking it.

• Bending: Bend the acp to fit your project.

• Assembling: Put all the layers together to make the finished panel.

You check the quality at every step. You look at the aluminum to see if it is straight and looks good. You test the core to see if it is strong and safe. You check the thickness and color of the anodized layer. You make sure the protective film is smooth and strong. These checks help you get acp that is very good.

Tip: Always buy anodized aluminum composite panels from trusted companies. Good checks during making mean your acp will last longer and look better.

Making anodized aluminum composite panels uses new machines and careful checks. You get panels that are strong, light, and easy to use. The anodized surface keeps your building safe and looking new. When you use acp made with care, your project turns out great.
