SGC340 galvanized steel sheet,SGC340 hot dip galvanized steel plate,SGC340 galvanized steel coil.cold rolled galvanized steel coil SGC340.Galvanized steel plate and coil SGC340 owned proof strength above 245 Mpa and tensile strength above 340 Mpa.Relative galvanized steel grades under JIS G3302:SGCC,SGHC,SGCH,SGCD1,
SGCD2,SGCD3,SGCD4,SGC340,SGC400,SGC440,SGC490,SGC570,SGH340,SGH400,SGH440,SGH490,
SGH540.Owning containing more Carbon elements,galvanized steel plate SGC340 has a higher tensile and proof strength.
JIS G3302 SGC340 hot dipped galvanized steel plate,after trolled and transport,dark spots may appear on the zinc coated surfaces as a result of friction.Generally,these spots only impair the appearance.Friction is reduced by oiling the galvanized steel plates and coils of SGC340,However,the following precautionary measures should be taken:secure packing,laid flat,no local pressure spots.
