Ntxiv rau kev tiv thaiv ntawm zinc txheej, cov organic txheej rau zinc txheej ua lub luag haujlwm hauv kev npog thiab tiv thaiv cov xim coated steel coil, tiv thaiv cov hlau kauj los ntawm xeb, thiab nws lub neej kev pab cuam yog kwv yees li 1.5 npaug ntev dua li ntawm galvanized steel kauj.
Cov xim pleev xim uas peb tuaj yeem ua 10-30microns.Qhov siab dua cov xim zaj duab xis, lub neej ntev ntawm cov xim.
Cov khoom siv pleev xim yog PE, SMP, HDP, PVDF, ects.
Pupolar xim ntawm ppgi steel kauj: caw liab (ral3005), nplaim liab (ral3000), Ruby liab (RAL3003), Teeb liab liab (RAL 3001), Coral liab (RAL 3016), tsheb liab (RAL 3020)
