GI galvanized steel kauj, galvanized sheet coil feem ntau muab faib ua ob hom: galvanized galvanized thiab tsis-galvanized raws li qhov loj ntawm zinc paj ntawm qhov tsos. Nws yog ib qho tsim nyog hlau rau nruab nrab thiab siab tshaj lub tsev steel qauv.
Galvanized steel yog ib qho ntawm ntau hom hlau. Nws yog tsuas yog siv rau hauv kev tsim kho kev lag luam, tsheb, thiab khoom siv hauv tsev. Nws yog cov hlau ntau yam hauv nruab nrab thiab qis dua ntawm kev lag luam steel. Nyob rau hauv xyoo tas los no, nws cov cwj pwm nyiaj txiag tau nce ntxiv nrog kev cuam tshuam ntawm cov khoom siv raw kub dov coils.
Gigalvanized steel coilsyog tsim los ntawm txias yob nyob rau hauv txawv specifications nrog zinc txheej rau saum npoo, tiv thaiv cov hlau nto los ntawm corrosion, thiab kom lengthen kev pab cuam lub sij hawm.Lub nto muaj siab decoratively ci grey xim thiab tsis tu ncua spangle.
