SGHC is the base material SPHC 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 SGHC is for commercial use
SGHC steel Applicable thickness is 1.6mm or over up to and including 6.0mm
SGHC 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
SGHC steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGHC steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGHC steel tensile test characteristics:
yield strength :should be not less than 205MPa
tensile strength should be not less than 270MPa
Elongation does not specify
