Amabhodi kathayela avame ukuhlukaniswa ngezindlela ezahlukahlukene ngokuya ngesiza sokufaka isicelo, ukuphakama kwamagagasi ebhodi, ukwakheka kwamathanga, nezinto ezibonakalayo.
Izindlela ezijwayelekile zokuhlukanisa zimi kanje:
(1) Ngokwezigaba zezingxenye ezisetshenziswayo, ihlukaniswe ngamaphaneli ophahleni, amaphaneli odonga, amadekhi aphansi kanye namaphaneli osilingi. Esetshenziswayo, ipuleti lensimbi lombala lisetshenziswa njengebhodi lokuhlobisa odongeni ngesikhathi esifanayo, futhi umphumela wokuhlobisa wezakhiwo uyinoveli futhi uhlukile.
(2) Ngokwesigaba sobude begagasi, ihlukaniswe ngepuleti lamagagasi aphezulu (ubude begagasi ≥70mm), ipuleti lamagagasi aphakathi nendawo kanye nepuleti lamagagasi aphansi (ubude begagasi <30mm)
(3) Ukuhlelwa ngokwempahla ye-substrate - ihlukaniswe yaba i-hot-dip galvanized substrate, i-hot-dip aluminium substrate, kanye ne-hot-dip aluminium substrate.
(4) Ngokwesakhiwo somphetho webhodi, ihlukaniswe yaba i-lap joint, i-undercut kanye nesakhiwo sokugodla, njll. Phakathi kwazo, amabhodi amagagasi aphakathi nendawo kanye nama-wave aphezulu kufanele asetshenziswe njengamaphaneli ophahleni anezidingo eziphakeme zokungangeni kwamanzi: i amashidi amagagasi aphakathi nendawo naphezulu agqitshiwe asetshenziswa njengezembozo zaphansi; amabhodi amagagasi aphansi anelaphu asetshenziswa njengamaphaneli odonga.
