ISO9364-2001 is a international standard. ISO9364-2001 specifies the characteristics of steel of commercial, drawing and structural quality coated by a continuous hot dipped aluminum/zinc alloy coating process. The aluminum/zinc alloy composition by mass is nominally 55% aluminum, 1.6% corrosion characteristic of aluminum couple with these of zinc are desired.
The main material under ISO9364-2001 standard:
1 hot dipped aluminum/zinc steel sheet, 1 hot dipped aluminum steel strip,
2 hot dipped aluminum/zinc steel sheet, 2 hot dipped aluminum steel strip,
250 hot dipped aluminum/zinc steel sheet, 250 hot dipped aluminum steel strip,
350hot dipped aluminum/zinc steel sheet, 350 hot dipped aluminum steel strip,
550 hot dipped aluminum/zinc steel sheet, 550 hot dipped aluminum steel strip.
Coating type: the type of coating is designated as:

Continuous hot dip aluminum zinc coated steel sheet
Product obtained by hot dipped coating steel sheet coils on a continuous aluminum zinc coating line to produce either coated coils or cut lengths
Type of aluminum zinc coating
Normal spangle finish coating: coating formed as a result of unrestricted growth of aluminum zinc crystals during normal solidification
ISO9364-2001 aluminum/zinc steel Smooth finish: smooth finishing produced by skin-passing the coated material in in order to achieve an improved surface condition as compared with the normal as coated product.
