Ngokujwayelekile isetshenziselwa amabhuloho omzila wezitimela anezikhala ezincane.
Ku-truss, i-chord amalungu akha i-periphery ye-truss, okuhlanganisa i-chord ephezulu kanye nechord ephansi. Amalungu axhuma amachords aphezulu naphansi abizwa ngokuthi amalungu ewebhu. Ngokwezikhombisi-ndlela ezihlukene zamalungu ewebhu, ahlukaniswe ama-diagonal rods kanye nezinduku eziqondile.
Indiza lapho ama-chords nama-webs etholakala khona ibizwa ngokuthi indiza ehlanganisa ama-main. Ukuphakama kwebhuloho lebhuloho elikhulukazi kuyashintsha ngokuhambisana ne-span ukuze kwakheke intambo egobile; ama-spans aphakathi nendawo amancane asebenzisa ukuphakama kwe-truss okuqhubekayo, okubizwa ngokuthi i-flat string truss noma intambo yentambo eqondile. Isakhiwo se-truss singakhiwa sibe ibhuloho noma ibhuloho le-arch, futhi singasetshenziswa njengesigxobo esiyinhloko (noma i-stiffening beam) ebhulohweni lesistimu yokusekela ikhebula. Iningi lamabhuloho ama-truss akhiwe ngensimbi. Ibhuloho le-truss liyisakhiwo esingenalutho, ngakho-ke likwazi ukuzivumelanisa nezimo ezinhle kudekhi ephindwe kabili.
Ibhuloho le-Steel truss lihlanganisa izinzuzo zensimbi nesakhiwo se-truss:
1. Isakhiwo esikhanyayo kanye nekhono elikhulu lokuhlanganisa
2. Kulula ukulungisa nokufaka esikhundleni
3. I-steel truss beam inamalungu amaningi namanodi, isakhiwo siyinkimbinkimbi kakhulu, futhi ukuzinza kunamandla.
I-4.Ukumelana okuqinile nokucindezela nobuqotho obuhle
5. Uhlu olubanzi lokusetshenziswa
