Chitsulo chachitsulo cha hull chimagawidwa m'magulu amphamvu malinga ndi mfundo yake yochepa yokolola: zitsulo zamagulu amphamvu kwambiri komanso zitsulo zamphamvu kwambiri.
Chitsulo chokhazikika champhamvu cha China Classification Society chimagawidwa m'magulu anayi: A, B, D, ndi E;Chitsulo champhamvu kwambiri cha China Classification Society muyezo ndi magiredi atatu amphamvu ndi magiredi anayi apamwamba:

3. Chiyambi cha sitima yapamadzi Chitsulo chambiri champhamvu chamtundu wa hull chimagawidwa m'magulu anayi: A, B, D ndi E. Mphamvu zokolola (osachepera 235N / mm ^ 2) ndi mphamvu zamakokedwe (400～520N / mm ^ 2) ndi yofanana, koma mphamvu mphamvu pa kutentha osiyana ndi osiyana;chitsulo cholimba champhamvu kwambiri chimagawidwa m'makalasi amphamvu malinga ndi mphamvu zake zochepa zokolola, ndipo giredi iliyonse yamphamvu imagawidwa kukhala A, D, E malinga ndi kulimba kwake.F4 gawo.Mphamvu zokolola za A32, D32, E32 ndi F32 sizichepera 315N/mm^2, ndipo mphamvu yamakokedwe ndi 440～570N/mm^2.-40 °, -60 ° zimakhudza kulimba;mphamvu zokolola za A36, D36, E36, F36 sizichepera 355N/mm^2, mphamvu zamakokedwe ndi 490～620N/mm^2, A, D, E ndi F zikuyimira kulimba kwamphamvu komwe kungapezeke pa 0°, -20 °, -40 °, ndi -60 ° motero;mphamvu zokolola za A40, D40, E40, ndi F40 sizichepera 390N/mm^ 2. Mphamvu yokhazikika ndi 510～660N/mm^2, ndipo A, D, E, ndi F imayimira kulimba komwe kungathe kukhala. akwaniritsa pa 0 °, -20 °, -40 °, ndi -60 ° motero.
