SGCC Galvanized Steel Sheet
JIS G3302 hot-dip galvanized commercial quality
SGCC is the Japanese-standard galvanized sheet grade, widely specified across Southeast Asia and the Middle East. In practice it is the commercial-quality equivalent of DX51D+Z: soft, formable, easy to bend and weld, with zinc coatings from 60 to 275 g/m². Most of the galvanized sheet moving in containers from China is sold against this designation or its EN twin.
