ALUMINUM SILICON COATED STEEL

Superior Heat Resistance and Corrosion Protection

Aluminum-silicon coated steel (AS) is ideal for components requiring high-temperature corrosion resistance. It is the material of choice for demanding environments where thermal loads and corrosion risks intersect. At CHY Steel Service, part of Oz Metal Group, we combine this specialized material with our precision processing to ensure it meets your exact manufacturing requirements.

Due to its unique properties, AS coated steel is widely used in automotive exhaust systems, including mufflers and pipes, as well as in heat shields or thermal protection sheets. Additionally, it is a critical material for exhaust flues and gas boiler components.

FEATURES AND ADVANTAGES

Strength of Steel, Resistance of Aluminum

Aluminum-silicon coated steel uniquely combines the mechanical strength of steel with the corrosion resistance of aluminum:

01
High Temperature Resistance

Ideal for components exposed to high heat, maintaining integrity and resisting oxidation.

02
Excellent Corrosion Protection

Al-Si coating provides superior barrier protection against atmospheric and exhaust gas corrosion.

03
Premium Fuel Resistance

Due to specific surface properties, AS steel is ideal for fuel tanks and fuel systems.

04
Forming Versatility

Suitable for complex forming processes found in automotive and white goods manufacturing.
