Kub Dipped Galvanized Coil
Galvanized steel kauj, immersing lub nyias steel phaj nyob rau hauv lub molten zinc da dej, thiab adhering ib txheej ntawm zinc nyias steel phaj rau saum npoo. Nws yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, coiled steel phaj yog txuas ntxiv rau hauv zinc-melted plating tank los ua galvanized steel phaj; alloyed galvanized steel phaj. Hom steel phaj no kuj yog ua los ntawm kub -dip txoj kev, tab sis nws yog rhuab mus txog 500℃tam sim ntawd tom qab tawm hauv lub tank los ua ib tug alloy zaj duab xis ntawm zinc thiab hlau. Qhov no galvanized steel kauj muaj cov xim zoo adhesion thiab weldability.
