Xa i-workpieces yensimbi yemitha, ukukhethwa kwentsimbi, ngokuqhelekileyo kuqwalaselwa eyona nto iphambili: iimpawu zomatshini (amandla, ukuqina, njl.), ukusebenza kokucubungula kunye neendleko.Kodwa kumacandelo e-galvanized, ukubunjwa kokukhethwa kwezinto eziphathekayo, umgangatho we-hot-dip galvanizing unempembelelo enkulu.

Enye ye-corrosion ye-galvanized steel corrosion indlela yokuthintela kwiindawo ezahlukeneyo kodwa kufuneka ithathele ingqalelo ukusetyenziswa kweempawu, phantse yonke intsimbi ifanelekile kwi-galvanizing eshushu-dip, njengentsimbi eshushu, epholileyo, intsimbi ephosiweyo, intsimbi ebunjiweyo, izinto ezenziwe ngentsimbi ezifana nentsimbi, ubukhulu becala kwi-anti-corrosion ingaba shushu-dip galvanizing indlela, ukuze kuphuculwe ubomi.

Ubungakanani obusetyenzisiweyo ngekhabhoni eqhelekileyo kunye ne-alloy ephantsi-ukuqina okuphezulu kolwakhiwo lwentsimbi yeemveliso zegalvanized zezona zixhaphakileyo.Nangona kunjalo, izithako eziphambili zeekhemikhali zokufumana i-galvanized layer yezinto zentsimbi zezi: umxholo wekhabhoni ≤0.25%, umxholo we-phosphorus ≤0.04%, umxholo we-manganese ≤1.35%, umxholo we-silicon ≤0.03% okanye 0.15% ~ 0.25% (0.03% ukuya I-0.15% yelahleko yentsimbi enobudlova, i-workpiece yesikhumba esimnyama, i-peeling).Ngokucacileyo, ayizizo zonke iikhabhoni eziqhelekileyo kunye ne-alloy-alloy high-strength-stric structure ihlangabezana neemfuno zolu luhlu lokubunjwa.
