ASNSWER: SA1D is a Hot dip Aluminized steel material grade under JIS G3314 standard, SA1D also should be called Aluminium-Silicon(AS) steel, because it’s surface coating is 92%-89% Al + 8%-11% Si.
SA1D Aluminized steel have three level Surface quality, they are : As coated surface (A), Improved surface (B), Best quality surface(C). Usually the standard surface quality we supplied is Level B.
SA1D Aluminium-Silicon(AS) Coating masses are : AS40, AS60, AS80, AS100, AS120. However the Surface treatment are C,M,O,X

SA1D is the drawing quality Aluminized steel, so it request a strict Elongation rate data.
During the thickness 0.3mm-≤0.4mm, Elongation should be not less than 28%
During the thickness 0.4mm-≤0.6mm Elongation should be not less than 30%
During the thickness 0.6mm-≤1.0mm Elongation should be not less than 32%
When the thickness Above 1.0mm, Elongation should be not less than 34%
