What Is Color Coated Aluminum Strip?

Prepainted aluminum strip refers to aluminum strip that has been pretreated and painted with a certain thickness of paint film beforehand. The strip is often used for the production of various corrosion-resistant equipment, such as roofing, gutters, and chemical reactors. The advantages of prepainted aluminum strip include convenient installation, good appearance, and high corrosion resistance.

When selecting the coating paint of prepainted aluminum strip, the following factors need to be considered.

Use environment

The size and type of wear kinetic energy in the use environment need to be understood, which is very important for choosing wear-resistant coating materials. For example, if the prepainted aluminum strip needs to be used for outdoor architectural decoration, the coating paint material that can resist ultraviolet rays, humidity and temperature changes needs to be selected.

Paint material hardness

The greater hardness of the wear-resistant coating paint material on the prepainted aluminum strip, the better the wear-resistant performance will be. Therefore, you need to choose the appropriate material hardness according to the specific use environment and requirements.

Corrosion resistance

Wear-resistant coatings need to be able to be used for a long time in different environments and resist corrosion. Therefore, you need to choose a coating material with good corrosion resistance.


Besides coating performance needs to be considered,and also the cost. In order to meet the use of the premise of the requirements, we should choose the moderate price and stable performance of the coating material.

Service Life

In normal,the service life can reach up to 15 years which use PE paint coating aluminum.And it can been around 25 years if PVDF paint coating.

Why Color Coated Aluminum Strip Owns Great Corrosion Resistant?

The anti-corrosion principle of pre-painted aluminium strip mainly works as follows:
Firstly, there is aluminium self-sacrificial anodic protection. As aluminium is more active than iron, aluminium acts as the negative pole, giving electrons to the positive pole of iron when they contact each other. This process protects iron from corrosion. This mechanism is known as "self-sacrificial anode protection".

Secondly, there is coating isolation. The pre-painted aluminium strip is coated with a layer of paint that shields it from air and moisture and prevents it from directly contacting corrosion sources.
The surface coating is dense and hard, effectively withstanding physical and chemical corrosion.

Chemical stability: The coatings applied to pre-painted aluminium strips exhibit excellent chemical stability and can effectively prevent various forms of chemical corrosion.

In essence, pre-painted aluminium strips achieve their anti-corrosion properties through a combination of self-sacrificial anodic protection, coating isolation, mechanical protection, and chemical stability of aluminium. These protective mechanisms synergize to provide pre-painted aluminium strips with superior corrosion resistance.
Additionally, pre-painted aluminium strip can be utilised in producing diverse profiles including window frames, door frames, and curtain walls. It can also be utilised for light metalwork and other situations that necessitate an excellent corrosion-resistant finish and high-quality appearance.
