Maboti a nangula nthawi zambiri amagwiritsa ntchito Q235, Q345, yomwe ndi yozungulira yopepuka. Sindikuganiza kuti ndawonapo ulusi womwe ukugwiritsidwa ntchito, koma osati ngati mphamvu ikufuna. Rebar (Q345) ndi yamphamvu kwambiri, kupanga ulusi wa mtedza sikophweka ngati kuzungulira kopepuka. Pa bawuti ya nangula yozungulira, kuya kokwiriridwa nthawi zambiri kumakhala kuwirikiza ka 25 m'mimba mwake, ndiyeno pangani mbedza ya digirii 90 kutalika kwa 120mm. Ngati bawuti awiri ndi lalikulu kwambiri (monga 45mm) kukwiriridwa mozama kwambiri, mukhoza kuwotcherera mbale lalikulu kumapeto kwa bawuti, ndiye mutu waukulu akhoza kukhala (koma pali zofunika zina). Kuzama kokwiriridwa ndi mbedza yopindika ndikuwonetsetsa kuti pali mkangano pakati pa bawuti ndi maziko, kuti asachotse kuwonongeka kwa bawuti. Choncho, mphamvu yachitsulo ya nangula ndi mphamvu yachitsulo yozungulira yokha, kukula kwake ndi kofanana ndi gawo lachigawo chochulukitsidwa ndi mtengo wamtengo wapatali wa mphamvu zowonongeka (140MPa) ndi mapangidwe a mphamvu zovomerezeka zovomerezeka. Kuthekera kokwanira kwambiri ndi gawo lachigawo (panthawiyi, malo ogwira ntchito pa ulusi) wochulukitsidwa ndi mphamvu yamphamvu yachitsulo (Q235 mphamvu yokhazikika ndi 235MPa). Monga momwe mtengo wapangidwe umakondera ku chitetezo, kulimba kwa kapangidwe kake kumakhala kocheperako kuposa mphamvu yomaliza.
