Dongkuk CM GLX Al-Zn-Mg Coated Steel Sheet (Mg-Alloyed Galvalume)

Dongkuk CM GLX Al-Zn-Mg Coated Steel Sheet (Mg-Alloyed Galvalume)

GLX is a next-generation Galvalume: a hot-dip aluminum-zinc-magnesium-silicon alloy coating (Al 55%, Zn-Mg 43.4%, Si 1.6%) designed for applications requiring high corrosion resistance. Patented in Korea, Australia, China and Taiwan.

Key features

  • Mg stabilizes zinc's sacrificial action, protecting cut edges and scratches from bending or site installation
  • Flat-part corrosion resistance over 60% higher than other high-corrosion alloy-coated sheets tested (per brochure)
  • No discoloration in sustained use at 315 C; up to 370 C intermittently
  • More than twice the heat reflexibility of galvanized steel
  • Paints without additional pre-treatment; base for LUXTEEL pre-painted steel
