Xinyu Zn-Al-Mg Coated Steel: Hardcore Protection for Diverse Applications.
Publish time: 2026.01.23

Coated steel sheets are prone to corrosion at cut edges and scratches under external environmental influences. These weak points can become "breach points" for rust, continuously deteriorating and accelerating damage to the steel sheet. So, how can we better protect these cut edges while maintaining corrosion resistance?

Tianjin Xinyu's Zinc-Aluminum-Magnesium Coated Steel provides the perfect solution.

Xinyu's ZAM coated steel innovatively employs a multi-alloy coating technology. It utilizes a scientific ratio of zinc, magnesium, and aluminum core components. Under strict process control, these form a dense protective coating consisting of a ternary eutectic structure of zinc, aluminum, and MgZn2, significantly extending service life.

Superior Corrosion Resistance

Test data shows that for product samples with a zinc coating weight of 275g/㎡, the neutral salt spray test (SST) results reach ≥4800 hours without red rust. This demonstrates excellent resistance to erosion from humid and other harsh external environments.

On Flat Surfaces: The synergistic effect of zinc, aluminum, and magnesium generates a dense oxide film on the steel surface. This film effectively blocks corrosive agents, granting the sheet excellent alkali resistance and red rust resistance.

At Cut Edges: When a cut or scratch exposes the base metal, the active magnesium and zinc elements in the coating proactively form zinc-magnesium oxides. This action "self-heals" the damaged area, blocking the spread of red rust and greatly enhancing cut-edge protection.
