QhiaGnee steelSab saum toj - ntawm - {line} Kab Galvanized Steel Co, tsim kom tau raws li cov qauv siab ntawm kev ua tau zoo thiab ua tau zoo. Engineered nrog precision thiab coated nrog ib txheej ntawm zinc, peb galvanized steel co tshuab roj muaj zog, ua rau lawv zoo tagnrho rau ntau cov ntawv thov.
Kub - dipped galvanized steel chev yog ib hom khoom siv steel uas tau sib xyaw nrog ib txheej ntawm kev tiv thaiv nws los ntawm kev corrosion. Cov txheej txheem cuam tshuam nrog tus hlau chev rau hauv da dej ntawm molten zinc, uas ua rau daim ntawv sib thooj metallurgical nruab nrab ntawm zinc thiab cov hlau.
Cov txheej no muab cov ruaj khov thiab ntev -} kav hlau, ua rau nws siv ntau yam xws li kev tsim kho, thiab kev tsim khoom lag luam.
