What is aluminum zinc coated steel? Many people are not familiar with it, so let me, the LangZo Steel editor, give you a simple introduction.
Aluminum Zinc Coated Steel:
Aluminum zinc coated steel is an aluminum-silicon alloy coated steel plate, where aluminum makes up 90% and silicon makes up 10%. This type of coated steel has excellent heat resistance, thermal reflectivity, and corrosion resistance. Its mechanical and physical properties are superior to cold-rolled steel. Due to its excellent performance, aluminum zinc coated steel has been widely used in everyday products such as car silencers and household appliances.
The surface of aluminum zinc coated steel is smooth and flat, with a silver-white base color. Its unique coating structure provides excellent corrosion resistance. The normal lifespan of this plate can reach 25 years, and it has good heat resistance, making it suitable for environments up to 315°C. The coating has good adhesion with the paint film, and the material has good processing performance, including punching, shearing, and welding. Additionally, it has good electrical conductivity.
The thermal reflectivity of aluminum zinc coated steel is much higher than that of galvanized steel, being twice as high, and it is commonly used as thermal insulation material.
Characteristics of Aluminum Zinc Coated Steel:
Aluminum zinc coated steel is an alloy structure with its main components being aluminum (about 55%), zinc (43.4%), and 1.6% silicon. This coating is formed at high temperatures, making it highly resistant to corrosion and exceptionally durable.
It has high thermal reflectivity and good heat resistance. Compared to galvanized steel, it is slightly more expensive but has a longer lifespan, offering high cost-performance.
Aluminum zinc coated steel has a higher thermal reaction performance, more than twice that of galvanized steel, and can be used as insulation material. It can also withstand temperatures over 300°C, making it suitable for applications such as chimney pipes or fluorescent light covers.
Moreover, it is easy to paint, with excellent adhesion, and does not require weathering treatment before painting. It can be directly painted on the steel plate. Its processing and coating performance are also excellent, making it ideal for industries like construction, automotive, and household appliances.
Difference Between Aluminum Zinc Coated Steel and Galvanized Steel:
The main difference between aluminum zinc coated steel and galvanized steel lies in the composition of the coating. Galvanized steel has a coating that provides protection and enhances its corrosion resistance.
Aluminum zinc coated steel has a coating made of aluminum, zinc, and other elements, forming a honeycomb-like structure that also provides protection. However, once the steel is cut, it may develop corrosion, so it is important to minimize cutting to extend its lifespan.
If cutting is necessary, it is important to protect the edges, for example, by applying rust-proof paint, which will prolong the lifespan and prevent corrosion.
