Galvalume Steel

Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than 800 °C (1,470 °F).

  • Displays excellent high reflectivity characteristics. At temperatures up to 842 °C (1,548 °F), aluminized steel reflects up to 80% of heat projected onto it.
  • Aluminized steel can maintain its strength at temperatures up to 677 °C (1,251 °F). Although stainless steel is the stronger of the two, aluminized steel has a greater electrostatic surface, and can therefore reflect heat better.
  • Aluminized steel is highly resistant to corrosion because of the thin layers of aluminium and silicon, which keep the underlying steel from oxidizing.
