Bututun ƙarfe mara kauri mai kauri:

Nauyi mai nauyi: Bututun ƙarfe masu kauri suna da nauyi, kuma ana buƙatar manyan kayan ɗagawa yayin sufuri, kuma kayan aikin sufuri suna buƙatar samun isassun ƙarfin ɗauka.
Stacking Stacking: Saboda nauyin nauyin bututun ƙarfe, ya kamata a yi la'akari da daidaito da kwanciyar hankali yayin tarawa don guje wa jujjuyawa ko tipping, musamman lokacin sufuri don hana zamewa ko karo.
Tsaron sufuri: A lokacin sufuri mai nisa, ya kamata a ba da kulawa ta musamman ga kayan aiki irin su ɓangarorin hana zamewa da shingen tallafi tsakanin bututun ƙarfe don guje wa lalacewa ta hanyar rikici da tasiri.
Farashin bututun ƙarfe mara nauyi na bakin ciki ba ya da ɗanɗano kaɗan, amma ya kamata a ba da hankali don hana nakasawa da lalacewar ƙasa yayin sufuri; yayin da farashin bututun ƙarfe mara nauyi mai kauri ya fi girma, kuma ya kamata a ba da kulawa ta musamman ga aminci, kwanciyar hankali da sarrafa nauyi yayin sufuri. Duk da haka, bututun ƙarfe maras nauyi tare da kayan musamman da ƙayyadaddun bayanai har yanzu suna buƙatar ƙima da gaske.
