Special High Grade Zinc (SHG) is a high purity grade of zinc (99.990% Zn minimum) used in hot-dip and electro-galvanizing and as a component of brass alloys. SHG-Zinc suits all applications and can be mixed with other alloying elements.
Special high-grade zinc of 99.995% purity (minimum) must conform to the chemical composition of one of the following standards:

  • BS EN 1179:2003 – 99.995% grade
  • ISO 752:2004 – ZN-1 grade
  • ASTM B6-12 – LME grade
