A o le mita uʻamea workpieces, o le filifilia o le uamea, e masani lava o le manatu autu o le: o mea faʻainisinia (malosi, faigata, ma isi), gaioiga gaioiga ma tau.Ae mo vaega galvanized, o le tuufaatasiga o le filifilia o meafaitino, o le lelei o le vevela-dip galvanizing e tele se aafiaga.

O se tasi o corrosion o u'amea u'amea puipuia auala puipuia mo le tele o siosiomaga ae e tatau ona gauai atu i le faaaogaina o foliga, toetoe lava o le uamea uma e talafeagai mo le vevela-dip galvanizing, e pei o le uʻamea vevela, uamea malulu, lafo uamea, u'amea u'amea, lafo u'amea mea e pei o le uamea, tele mo le anti-corrosion e mafai ona vevela-dip galvanizing auala, ina ia faaleleia ai le olaga.

Aofa'i fa'aoga masani carbon ma maualalo-alloy maualuga-malosi fausaga uamea oloa u'amea sili ona taatele.Ae ui i lea, o mea autu o vailaʻau e maua ai le mea sili ona lelei o le uʻamea o le mea uamea o: carbon content ≤0.25%, phosphorus content ≤0.04%, manganese content ≤1.35%, silicon content ≤0.03% poʻo 0.15% ~ 0.25 % (0.03% i le 0.15% o uʻamea gau gau, o le mea faigaluega paʻu pogisa, paʻu).E manino lava, e le o mea uma o le kaponi masani ma le maualalo-alloy maualuga-malosi fausaga fausaga e fetaui ma manaʻoga o lenei vaega tuʻufaʻatasia.
