Galvanized Steel Sheet ee Kulul (GI) waxaa lagu soo saaraa iyada oo gudbisa xaashida Full Hard ee soo martay habka dhaqidda aashitada iyo rogrogmada iyada oo la marayo dheriga Zinc, markaas oo lagu dhejiyo filimka zinc dusha sare.Waxay leedahay iska caabin daxalka oo heer sare ah, rinjiyeyn, iyo karti shaqo taasoo ay ugu wacan tahay sifooyinka Zinc.Caadi ahaan, xaashida birta galvanized ee kulul iyo habka gariiradda birta galvanized iyo qeexitaannada asal ahaan waa isku mid.
Galvanization-ku-kulul waa habka loo mariyo daahan zinc-ka-ilaalinta xaashida birta ah ama birta, si looga hortago daxalka.
Ka-hortagga daxalka, rinjiyeynta, iyo socodsiinta heer-sare ee heer sare ah sababtoo ah dabeecadda naf-hurid ee zinc.
La heli karo si loo doorto oo loo soo saaro qaddarka la rabo ee zinc dahabka leh iyo gaar ahaan waxay awood u siinaysaa lakabyada zinc qaro weyn (ugu badnaan 120g/m2).
Lagu kala saaraa mid eber ah ama mid siman oo dheeraad ah iyadoo ku xiran in xaashida lagu sameeyo daawaynta gudubka maqaarka.
