Njengomthetho, amasistimu odonga lwamakhethini anamathele ahlanganisa amalungu aqondile naqondile anwebekayo ('induku') eyaziwa ngokuthi ama-mullions nama-transom ngokulandelanayo. A ejwayelekileikhethini odongeni uhleloizoxhunywa kuma-slabs aphansi ngamanye, anezingilazi ezinkulu zengilazi ezinikeza umbono wangaphandle kanye namaphaneli e-opaque e-spandrel afakwe ukufihla uhlaka lwesakhiwo.
Ngokuphathelene nodonga lwamakhethini olunamathele, ama-mullions nama-transoms ngokuvamile akhiqizwa kusukela ezingxenyeni ze-aluminium extruded, ezinganikezwa ngezinhlobonhlobo zobukhulu bezigaba ezihlukene, imibala kanye nokuqedwa emakethe. Ngaleso sikhathi, ama-mullions nama-transoms axhunywe ndawonye kusetshenziswa ama-engeli, ama-cleats, ama-toggles noma iphinikhodi yokubeka elulaukwakhiwa kodonga lwamakhethini. Izigaba ezihlukahlukene nokuxhumana kuyatholakala ngomthamo ohlukile wokulayisha ukuze kwakhiwe umklamo odingekayo. Ubukhulu bezigaba bulawulwa ubude obuvundlile phakathi kwamamiliyoni kanye nokuphakama phakathi kwama-slabs aphansi esakhiwo, imithwalo yemvelo efana nomoya, nesisindo sengilazi. Ngaphezu kwalokho, iphaneli yengilazi iklanyelwe ukuhambisana nesistimu futhi ngokuvamile ihlinzekwa ngumkhiqizi wengilazi ohlukile.
Uma kuqhathaniswa ne-audonga lwamakhethini oluhlanganisiweohlelweni, izingxenye zohlelo lwezinduku zivame ukwakhiwa (zisikwa zibe ubude futhi zilungiselwe ukuxhunywa) ngaphakathi kwefekthri bese zithunyelwa endaweni njengekhithi yezingxenye ezisuke zifakwe ithimba losonkontileka abangochwepheshe. Uma igridi ye-mullion/transom isimisiwe, amafasitelana engilazi namaphaneli e-spandrel amiswa futhi ngokuvamile abanjwa endaweni yawo ngamapuleti okucindezela ambozwa amakepisi ekhava. Enye indlela yokubopha ingilazi ukuguqula ukucwebezela okusebenzisa umgudu phakathi kwengilazi ukuze ubambe i-laminate yangaphakathi kuphela. Ekusetshenzisweni okungokoqobo, izinzuzo zodonga lwamakhethini enduku zihlanganisa uhlelo olungcono lokulethwa kwezinto kanye namandla okonga imali ezindlekweni zabasebenzi. Izinto ezisetshenziswayo zizofika emalolini apakishwe ngempumelelo ngangokunokwenzeka ukuze kukhuliswe ukuthi kungakanani okulethwa ohambweni olulodwa. Lokhu kuzonciphisa inani lamaloli angenayo naphumayo ngohlelo lwesiza esincane kangaka. Lokhu kuzoholela ezindlekweni zabasebenzi ezishibhile. Ngaphezu kwalokho, ngenxa yokuhlukahluka kwayo kanyeikhethini odongeni izindleko, lezi zinhlelo zivame ukusetshenziswa ezindaweni zokuthenga kanye nezakhiwo zamahhovisi ezisezingeni eliphansi.
