Surface finish
Type Surface Finish
  Regular   Standard spangles with flower pattern, suited for general use
  Zero   More minimized spangles than regular, with a beautiful gloss, suited for general painting applications
  Ultra   Extremely minimized spangles suited for special painting applications
  Alloy coated iron-zinc   Gal annealed steel sheet has a highly workable iron-zinc alloy layer. Good paint-adherence properties,   corrosion   resistance and weld ability make them ideal for use in home electrical appliances and buildings
