Isakhiwo sentsimbisisakhiwo esakhiwe ngezinto zetsimbi kwaye yenye yezona ntlobo zezakhiwo eziphambili. Ulwakhiwo ikakhulu luqulunqwe ngamaplanga entsimbi, iintsika zetsimbi, iintsimbi zentsimbi kunye nezinye izinto ezenziwe ngentsimbi yecandelo kunye neepleyiti zentsimbi, kwaye yamkela i-silanization, i-phosphating ecocekileyo ye-manganese, ukuhlamba kunye nokomisa, ukugalela kunye nezinye iinkqubo zokuthintela umhlwa. Amacandelo okanye amacandelo adla ngokudityaniswa nge-welds, i-bolts okanye i-rivets. Ngenxa yobunzima bayo obulula kunye nokwakhiwa okulula, isetyenziswa ngokubanzi kwiifektri ezinkulu, iindawo, izakhiwo eziphakamileyo eziphezulu, iiBridges kunye nezinye iindawo. Isakhiwo sensimbi kulula ukugqwala, isakhiwo sentsimbi ngokubanzi ukususa i-rust, i-galvanized okanye ipeyinti, kunye nokugcinwa rhoqo.
