What is ZINMAG?

ZINMAG is a high-corrosion-resistant coated steel with zinc, aluminum, and magnesium layers for severe environments.

It is positioned as a practical alternative to many conventional coated steel solutions.

Advantages

  • 3-5x corrosion resistance compared to equivalent GI coating levels
  • High abrasion and friction resistance
  • Reduced cut-edge corrosion
  • Lower white-rust tendency
  • Improved chemical and alkaline resistance
  • Lower maintenance and replacement costs

Specifications

  • Standards: AS1397, ASTM A1046/A1046M, JIS 3323
  • Thickness: 0.4 to 3.2 mm
  • Width: 900 to 1260 mm
  • Coating mass: ZM60 to ZM450

Anti-Corrosion Mechanism

Magnesium accelerates formation of a dense crystalline protective film (Simonkolleite) that reduces corrosive attack on the base steel.
