Makulidwe Opaka Chitsulo Chomata
Gwiritsani ntchito maubwenzi otsatirawa kuti muyerekeze makulidwe a zokutira kuchokera pa kulemera kwa zokutira [misa]:
1.00 oz/ft2 zokutira kulemera = 1.68 mils zokutira makulidwe,
7.14 g/m2 zokutira kulemera = 1.00 µm zokutira makulidwe.
Gwiritsani ntchito chiyanjano chotsatirachi kuti mutembenuzire kulemera kwa zokutira kukhala zokutira misa:

Dzina la zokutira ndi nthawi yomwe malo ochepera patatu, kulemera kwa mbali zonse ziwiri [kulemera] kumatchulidwa.Chifukwa cha mitundu yambiri ndi kusintha kwa mikhalidwe yomwe imakhala yodziwika ndi mizere yowonjezera yotentha yotentha, zokutira za zinki kapena zinki-zitsulo sizimagawanika mofanana pakati pa zigawo ziwiri za pepala lophimbidwa;komanso nthawi zonse sizimagawidwa mofanana kuchokera m'mphepete kupita kumphepete.Komabe, kulemera kwa mawanga atatu (kuchuluka) kumbali iliyonse sikuyenera kuchepera 40 % ya kufunikira kwa malo amodzi.
Monga ndi chowonadi chotsimikizika kuti kukana kwa mlengalenga kukana kwa zinc kapena zinc-iron alloy-coated sheet sheet ndi ntchito yachindunji ya makulidwe (kulemera (kulemera)), kusankha kwa zilembo zocheperako (zopepuka) kumabweretsa pafupifupi mzere. kuchepetsa dzimbiri ntchito zokutira.Mwachitsanzo, zokutira zolemera zamalati zimagwira bwino ntchito molimba mumlengalenga pomwe zokutira zopepuka nthawi zambiri zimakutidwa ndi utoto kapena zotchingira zofananira zomwe zimapangitsa kuti dzimbiri isawonongeke.Chifukwa cha ubalewu, zinthu zomwe zili ndi mawu oti "zikumana ndi ASTM A653/A653Mrequirements" ziyeneranso kufotokoza tanthauzo la zokutira.
Palibe zochepera zomwe zikutanthauza kuti palibe zofunikira zochepa zoyezetsa patatu ndi malo amodzi.
