Ngongole zitsulo zimagwiritsidwa ntchito kwambiri popanga zomangira, monga nsanja zotumizira magetsi othamanga kwambiri, mafelemu mbali zonse za girder yayikulu.zitsulo kapangidwemilatho, mizati ndi booms wa cranes nsanja pa malo omanga, mizati ndi matabwa mu zokambirana, etc. Malo ang'onoang'ono monga zikondwerero Alumali mu mawonekedwe a maluwa mphika amayikidwa panjira, alumali ndi mpweya wofewetsa ndi mphamvu ya dzuwa imapachikidwa. pansi pa zenera, etc.
Njira yopangira zitsulo za ngodya ndizosavuta. Kawirikawiri, makampani akuluakulu azitsulo samapanga chinthu ichi. Njira yopanga imatha kugawidwa m'mitundu iwiri: kugudubuza kotentha ndi kupindika kozizira. Kugudubuza kotentha kumagwiritsidwa ntchito ngati zitsulo zazikuluzikulu, ndipo kupindika kozizira nthawi zambiri kumakhala kochepa. Njira yokhazikika ndiyo kugwiritsa ntchito chitsulo chachitsulo (monga square billet) kuti pang'onopang'ono chikungidwe mu ∨ mawonekedwe kupyolera mu gawo lodzipereka lachitsulo chogudubuza mphero kwa maulendo angapo. Amapangidwa ndi kugudubuza mwachindunji (kupindika) kwa pepala kapena chitsulo chachitsulo. Palibe kusintha kwa arc kumbali ya mkati mwa ngodya, ndipo chifukwa chakuti imapangidwa ndi kupindika, kupanikizika kwapakati pa ngodya kumakhala kwakukulu, ndipo katundu wamakina ndi osauka. Mfundo yofunika kwambiri ndi yakuti zinthu sizikutsimikiziridwa. Ikhozanso kukhala "chitsulo chapansi". Chitsulo choterechi sichikhoza kupindika kapena kuwotcherera. Nthawi zambiri, mabowo aatali ndi aafupi amatha kubowola.
