| 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 | Galvannealed steel sheet has a highly workable iron-zinc alloy layer. Good paint-adherence properties, corrosion resistance and weldability make them ideal for use in home electrical appliances and buildings |

In order to guarantee its quality, this steel coil and sheet is severely tested on varied standards. We offer this steel coil and sheets in a range of specifications as per the demands of customers.
Features:
- High strength
- Elevated durability
- Hardness & ductility
- Compact design
Atmospheric Corrosion Resistance:
- Based on many year atmospheric corrosion R&D tests, it is estimated that 55% Al-Zn sheet will outlast G90 galvanized by two to four times in marine, industrial and rural atmospheres. 55% Al-Zn panels are still rust-free after 30 years in all but the severe marine environment. The estimated life of the 55% Al-Zn coating (years to first rust) based on these 30-years tests ranges from 14 years to 40 or more years.Thickness range is 0.2mm to 0.95mm.
We guarantee our products meet stated criteria and grades that include primary standards such as:
