ASK:
SGCH is the base material SPCC which are equally coated on both surfaces by hot dip zinc coating process. The composition by mass fraction is 97% or over zinc (provided that the aluminium content is usually 0.3% or less). The Application of SGCH is for commercial use of hard class.
SGCH steel Applicable thickness is 0.11mm or over up to and including 1.0mm
SGCH steel coating shall be classified into 2 types: non-alloyed coating and alloyed coating. Non alloyed coating mass are: Z06/Z08/Z10/Z12/Z14/Z18/Z20/Z22/Z25/Z27/Z35/Z37/Z45/Z60, Alloyed coating are: F04/F06/F08/F10/F12/F18
SGCH steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGCH steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGCH steel tensile test characteristics:
yield strength should be not less than 205 MPa,
tensile strength should be not less than 270 MPa,
