S250GD Galvanized hlau
S250GD yog tus cwj pwm los ntawm kev sib xyaw ua ke ntawm lub zog, ductility thiab corrosion kuj. Qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 250 N / mm² thiab lub zog tensile nyob rau hauv thaj tsam ntawm 360-510 N / mm² lav ib tug txhim khu kev qha load- bearing muaj peev xwm nrog txaus ductility. Ua tsaug rau qhov kub -dip galvanized nto, cov hlau ua tiav kev tiv thaiv corrosion ntev, ua rau nws tiv taus txawm tias huab cua hnyav thiab ib puag ncig kev lag luam.
Kub-dip galvanized steel S250GD raws li EN 10346 tus qauv yog siab-cov qauv hlau zoo uas tau tsim tshwj xeeb rau kev siv hauv kev tsim kho. Nrog rau cov khoom siv tooj 1.0242, S250GD muaj qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 250 N / mm² thiab yog li muab faib nyob rau hauv nruab nrab lub zog chav kawm ntawm kub -dip galvanized structural steels. EN 10346 tus qauv tsis tsuas yog qhia txog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, tab sis kuj txhais cov txheej txheem kub -dip galvanizing uas tsim kom muaj kev tiv thaiv ib puag ncig zinc txheej ntawm cov hlau. Cov txheej txheej muaj + Z, + ZF, + ZA, + ZM, + AZ thiab + AS ua kom muaj kev yoog raws qhov sib txawv ntawm ib puag ncig thiab cov xwm txheej thauj khoom.
