1) Ububanzi becandelo bukhulu, obuqinisekisa ukuba iimpawu zemishini yecandelo zisebenza ngokupheleleyo.
2) Ulwakhiwo lu-symmetrical kwaye kulula ukuphinda lusetyenziswe.
3) Uyilo lwesakhiwo secandelo lomnqamlezo lunengqiqo kwaye lunomgangatho ophezulu "womgangatho"
I-4) Ukusetyenziswa kweemfumba zentsimbi yentsimbi ayinakuthintelwa kwiimeko zemozulu.
5) Ulwakhiwo lunesiphumo esicacileyo sokukhusela okusingqongileyo, esinciphisa kakhulu isixa somhlaba esithathiweyo kunye nesixa sekhonkrithi esetyenzisiweyo, kwaye sikhusela ngokufanelekileyo ubutyebi bomhlaba.
6) Ukukhusela okuluhlaza kunye nokusingqongileyo.
7) Zifumaneka lula: Iimfumba zephepha ezibunjwe ngokuBanda ziveliswa ngobungakanani obuphezulu kuneengqumba zamaphepha ashushu, okonyusa inani lemihla yokuqengqeleka ekunokukhethwa kuzo.Ixesha lemveliso eqhelekileyo ziiveki ezi-2.
8) Ukonga imali: Ingqumba yamaphepha abandayo imalunga ne-30-40% ngaphantsi kwexabiso eliphantsi ukuvelisa kunenqwaba yamaphepha aqengqelekayo.
9) Ukuthutha akubizi mali ininzi: Ngenxa yenani elikhulu labenzi beengqumba zamashiti abandayo, maninzi amathuba okuba ufumane indawo yokusila ekufuphi kunokuba ubunokuthenga iingqumba zamashiti ashushu.Ukongeza, ukhetho olukhulu lweemfumba zamaphepha ezenziwe ngokubanda lunokukuvumela ukuba ufumane amacandelo anemodyuli yecandelo elikufutshane kwiinkcukacha zakho zoyilo ngaphandle kokunyuka okukhulu kobunzima.
I-10) Ukuguquguquka ngakumbi ekumiseni: I-interlocks ye-sheet-formed sheet pimple interlocks ivumela ukujikeleza kwe-25-degree, kunokuba i-7-to-10-degree-rotation ivunyelwe nge-hot-rolled sheet sheet usebenzisa i-ball-and-socket interlocks.
