Prepainted steel coils / cov ntawv los kuj tseem hu ua xim coated steel coils / cov ntawv, feem ntau yog ua los ntawm cov khoom siv (yob txheej) txheej ntawm cov ntaub ntawv nyob rau hauv av los yog ua ke cov organic zaj duab xis thiab tom qab ntawd ci mus rau hauv cov txheej / ntawv kawg. Cov txheej txheem qis yog galvanized steel coils (PPGI) lossis galvalume steel coils (PPGL), txhuas coils (PPAL).

Prepainted steel coils / cov ntawv yog cov tsev tsim kho tshiab sai sai hauv xyoo tsis ntev los no thoob plaws ntiaj teb. Nws raug tshuaj khes mis ua ntej, pib txheej, txheej txheej kawg thiab lwm cov txheej txheem hauv cov kab txuas ntxiv. Cov xim pleev xim rau yog qhov tsis sib xws, ruaj khov thiab zoo tagnrho, zoo tshaj li tus neeg txhuam cov xim txhuam lossis txhuam txhuam ntawm cov duab hlau.

Prepainted steel coils / sheet muaj kev ua kom zoo nkauj zoo, ua kom zoo, thiab muaj cov tshuaj tiv thaiv zoo corrosion. Lub txheej pleev xim rau zoo thiab yuav tsis hloov pauv mus ntev. Vim tias cov hlau ua tau raug hloov tuaj yeem hloov ntoo, nws yog cov khoom siv txig txuag, nrog kev txuag hluav taws xob, tiv thaiv kev ua qias tuaj thiab kev lag luam zoo.
