SGC440 is the base material SPC440 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 SGC440 is for commercial use of high strength class
SGC440 steel Applicable thickness is 0.25mm or over up to and including 3.20mm
SGC440 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
SGC440 steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGC440 steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGC440 steel tensile test characteristics:
yield strength :should be not less than 335MPa
tensile strength should be not less than 440MPa
Elongation should be not less than 18%
