Pamene mita workpieces zitsulo, kusankha zitsulo, kawirikawiri kuganizira waukulu ndi: katundu makina (mphamvu, toughness, etc.), processing ntchito ndi mtengo.Koma pazigawo zokhala ndi malata, kapangidwe ka kusankha kwa zida, mtundu wa galvanizing wotentha uli ndi mphamvu yayikulu.

Mmodzi wa dzimbiri kanasonkhezereka zitsulo dzimbiri njira kupewa zosiyanasiyana malo koma ayenera kulabadira ntchito mbali, pafupifupi zitsulo zonse ndi oyenera otentha-kuviika galvanizing, monga otentha adagulung'undisa, ozizira adagulung'undisa zitsulo, kuponyedwa zitsulo, zitsulo zopukutira, zitsulo zopangidwa ndi chitsulo monga zitsulo, makamaka zotsutsana ndi dzimbiri zimatha kukhala njira yotentha yovimbitsira galvanizing, kuti moyo ukhale wabwino.

Zambiri ntchito mpweya wamba ndi otsika aloyi mkulu-mphamvu structural zitsulo kanasonkhezereka mankhwala ambiri ambiri.Komabe, zosakaniza waukulu mankhwala kupeza kwambiri kanasonkhezereka wosanjikiza wa zinthu zitsulo ndi: mpweya zili ≤0.25%, phosphorous okhutira ≤0.04%, manganese okhutira ≤1.35%, pakachitsulo zili ≤0.03% kapena 0,15% ~ 0,25% (0.03% mpaka 0,15% ya kutayika kwachitsulo kwamphamvu, khungu lakuda, kupukuta).Mwachiwonekere, sizitsulo zonse za carbon ndi low-alloy high-mphamvu structural zitsulo zomwe zimakwaniritsa zofunikira zamtunduwu.
