ANSWER:SGLCC is a steel grade in Japanese standard JIS G 3321, SGLCC is general use quality steel material.The base material of SGLCC is cold rolled steel sheet.
+AZ means Application of an Aluminium-zinc coating by immersing the prepared strip in a molten bath of Aluminium-zinc-silicon. The composition of the bath is 55% of aluminium,1.6% of silicon and the balance zinc. So SGLCC means hot dip 55% Aluminium-Zinc alloy coated,general use quality material.
SGLCC material steel have coil, strip, sheet condition, thickness is from 0.24-2.3mm.
SGLCC steel coating finish is N(Normal spangle) or M(Minimized spangle)
SGLCC steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
SGLCC steel Surface treatment C (Chromization treatment) , NC (non Chromization treatment) ,M (non treatment) O (oiled), X (non oiled)
SGLCC steel Coating mass are: AZ70,AZ90,AZ120,AZ150,AZ170,AZ185,AZ200
SGLCC steel mechanical property:
Proof strength not specified
Tensile strength not specified
Elongation should be not less than 27%
