Scope

Main technical content: 3. Terms and Definitions 3.1 Hot-dip aluminum-zinc alloy coating The coating obtained by immersing pre-treated steel strips into a molten aluminum-zinc alloy bath on a continuous hot-dip aluminum-zinc production line. Note: The mass fraction of aluminum in the aluminum-zinc alloy bath should be 55% ± 1.5%, the mass fraction of zinc should be 43.5% ± 1.5%, and the mass fraction of silicon should be 1.5% ± 0.1%. 3.2 Sickle bend The maximum distance between the side of the product forming a concave shape and the straight line connecting the two end points of the measuring section of the steel strip. 3.3 Ratio of steepness to wave height 4. Designation Methods and Classification and Codes 4.1 Designation and Naming Methods The designation consists of the product usage code, the steel grade code (or serial number), the steel type characteristics (if any), the hot-dip code, and the coating type code, with a plus sign "+" connecting the hot-dip code and the coating type code. 5.
