Why are color-coated steel plates increasinglyreplaced by color-coated aluminum plates?

Due to the built-in anti-corrosion features of painted aluminum panels, they are increasingly replacing painted steel plates in various fields. So, what exactly are the advantages of painted aluminum plates that make them favored by building maintenance systems?

Good Durability and Built-in Anti-Corrosion Function
The aluminum molecules combine with oxygen in the air to form an aluminum oxide film that covers the surface of the aluminum plates. This prevents further oxidation and creates a natural protective layer, providing a built-in anti-corrosion function.

Lightweight, Reducing Support Structure Load
The density of alloy aluminum is 2.73, which is one-third that of steel. Its lightweight significantly reduces the load on support structures, making it widely used in large-span architectural fields such as airports, stations, and sports venues.

High Strength and Rigidity
By adding metal components like magnesium and manganese to the alloy aluminum plates, their strength and rigidity are greatly enhanced through the specific composition, improving their load-bearing capacity.

Good Plasticity and Easy Processing
Aluminum plates can be bent into straight sheets, inner curves, outer curves, and fan shapes, adapting to various roof designs—such as spherical, arched, and fan-shaped—maximizing the design concepts of architects.

Variety of Coatings and Colors, Customizable as Needed
The surface of aluminum plates can be coated in different colors and types of coatings according to architectural styles and design requirements, addressing cost and lifespan issues while fully showcasing the artistic effects of the building.

Recyclable and High Value
Ordinary painted steel plates can only be sold for a few cents per kilogram after being corroded, whereas painted aluminum plates can achieve recycling prices between 85% to 95% of the aluminum price, significantly exceeding the recycling value of ordinary painted steel plates.
