1. M'makampani opanga zinthu, nthawi zambiri amagwiritsidwa ntchito popanga ziwalo zomwe zimakhala ndi katundu wambiri, kupanikizika kwambiri, komanso kuvala kwambiri, monga zida, shafts, bearings, etc. moyo wautali wautumiki m'malo ovuta kugwira ntchito.Kuphatikiza apo, ilinso ndi kukana kutopa kwambiri komanso kukana dzimbiri, zomwe zimatha kukana kukokoloka kwa chilengedwe chakunja ndikuwonetsetsa kuti zidazo zikugwira ntchito mokhazikika.
2. Pa ntchito yomanga, chitsulo ichi chimagwiritsidwa ntchito kwambiri pomanga nyumba zazikulu monga milatho ndi nyumba zapamwamba chifukwa cha mphamvu zake komanso ductility zabwino.M'mapangidwe awa, amatha kupirira kupanikizika kwakukulu ndi kupsinjika maganizo, kuonetsetsa chitetezo ndi kukhazikika kwa nyumbayo.
3. Kuonjezera apo, ndi kusintha kwa chidziwitso cha chilengedwe, ntchito zokhudzana ndi chitetezo cha chilengedwe zikuchulukirachulukira.Mwachitsanzo, m'magalimoto amagetsi atsopano, amatha kugwiritsidwa ntchito popanga zida zazikulu monga ma mota ndi zochepetsera, zomwe zimathandizira kuyenda kobiriwira.Zimagwiranso ntchito yofunika kwambiri pazida zotetezera zachilengedwe monga kuyeretsa zimbudzi ndi kutulutsa mpweya wotayirira, kupereka chithandizo champhamvu pakuwongolera chilengedwe.
