Ukutyeba kweKoyile yeKoyile eGalvanized
Sebenzisa olu nxulumano lulandelayo ukuqikelela ukutyeba kokutyabeka ukusuka kubunzima bokugquma [ubunzima]:
1.00 oz/ft2 ubunzima bokugquma = 1.68 mils ukutyeba kokutyabeka,
7.14 g/m2 ubunzima bokugquma = 1.00 µm ubukhulu bokugquma.
Sebenzisa olu budlelwane bulandelayo ukuguqula ubunzima bokugquma bubunzima bokugquma:

Igama lokwaleka ligama apho ubuncinci bamachaphaza amathathu, bubonke ubunzima bokugquma amacala [ubunzima] buchazwe.Ngenxa yezinto ezininzi eziguquguqukayo kunye neemeko eziguqukayo ezibonisa imigca eqhubekayo yokugubungela i-hot-dip, i-zinc okanye i-zinc-iron alloy coating ayisoloko ihlulwe ngokulinganayo phakathi kweendawo ezimbini zeshidi elidibeneyo;kwaye ayisoloko isasazwa ngokulinganayo ukusuka kwelinye icala ukuya kwelinye.Nangona kunjalo, ubuncinci bobunzima bokutyabeka obunamabala amathathu (ubunzima) nakweliphi na icala abuyi kuba ngaphantsi kwe 40 % yemfuno yendawo enye.
Njengoko kuyinyani eqinisekileyo ukuba ukuxhathisa kwi-atmospheric corrosion ye-zinc okanye i-zinc-iron alloy-coated sheet sheet ngumsebenzi othe ngqo wokutyeba (ubunzima (ubunzima)), ukukhethwa kwezinto ezibhityileyo (ezikhaphukhaphu) zokwaleka kuya kubangela ukuba phantse ngokulandelelana. ukunciphisa ukusebenza kwe-corrosion ye-coating.Umzekelo, iileyiti ezinzima ezenziwe ngegalvan zisebenza ngokwanelisayo ekutyhilekeni okungqindilili kweatmosphere ngelixa iileyiti ezikhaphukhaphu zihlala zigqunywa ngepeyinti okanye isithintelo esifanayo sokunganyangeki kokuhlwa.Ngenxa yolu budlelwane, iimveliso ezithwele inkcazo "iyadibana ne-ASTM A653/A653Mrequirements" kufuneka icacise igama elithile lokwaleka.
Akukho buncinane buthetha ukuba akukho zimfuneko zisezantsi zovavanyo lwendawo ephindwe kathathu kunye neyendawo enye.
