ASNSWER: HX220BD+AS is a Hot dip Aluminized steel material grade under EN10346 standard, HX220BD+AS also should be called Aluminium-Silicon(AS) steel, because it’s surface coating is 92%-89% Al + 8%-11% Si.
HX220BD+AS 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.
The material grade of HX220BD+AS is 1.0919+AS.
HX220BD+AS Aluminium-Silicon(AS) Coating masses are : AS60, AS80, AS100, AS120, AS150 However the Surface treatment are C,O,CO,U,P, PO, S
