Cov qauv tsim muaj xws li lub kaum sab xis steel yees (quadrilateral thiab trilateral), ib leeg -tube yees, peb-tube yees, Guyed towers, rooftop towers/elevation frames, support poles, and scaffolding. Ntau hom yees muaj lawv tus yam ntxwv ntawm qhov siab, cua tsis kam, kev zoo nkauj, tus nqi tsim kho, thiab cov xwm txheej siv tau. Piv txwv li, ib leeg -tube yees yog feem ntau 15-50 meters siab, nrog rau qhov zoo xws li kev yooj yim, zoo nkauj, me me hneev taw, thiab kev tsim kho thiab kev teeb tsa sai. Qhov tsis zoo suav nrog cov cua tsis zoo vim yog cov qauv cantilever ntev, tus nqi siab, thiab kev teeb tsa nyuaj thiab kev saib xyuas. Quadrilateral lub kaum sab xis steel yees yog tsim rau ntau qhov siab, nrog rau qhov zoo xws li daim ntawv thov dav, kev ruaj ntseg zoo, kev nyab xeeb siab, thiab tus nqi tsim kho tsawg. Qhov tsis zoo suav nrog qhov loj dua, tsis tshua pom kev zoo nkauj, thiab siv sijhawm ntev dua. Trilateral lub kaum sab xis steel yees zoo ib yam li quadrilateral yees, tab sis lawv tag nrho cov qauv torsional tsis zoo, ua rau lawv tsis haum rau cov cua kub siab, tsis tuaj yeem ntsia rau saum cov chav tshuab, thiab yuav tsum tau hneev taw loj.
Piv nrog rau lub kaum sab xis steel yees, peb -tub yees muaj cov khoom tsawg dua, kev lag luam zoo dua, me me hneev taw, qauv yooj yim, thiab yooj yim rau kev thauj thiab nruab. Txawm li cas los xij, lawv muaj zog tsis muaj zog, lawv qhov siab yuav tsum tsis pub tshaj 55 meters, lawv tsis muaj qhov zoo nkauj, thiab kev txav chaw thiab rov siv dua yog qhov nyuaj. Guyed towers siv cov hlau tsawg, yooj yim rau txheej txheem thiab tsim, thiab muaj cov hauv paus tsis tshua muaj, tab sis xav tau qhov chaw loj rau cov txiv neej cov xov hlau, yuav tsum tau saib xyuas ntau zaus, thiab muaj kev nyab xeeb qis dua. Cov ncej txhawb nqa tau yooj yim rau nruab, yooj yim rau kev tsim, thiab pheej yig, tab sis muaj kev zoo nkauj tsis zoo thiab muaj peev xwm sib koom ua ke. Ncej mounts yog ib qho yooj yim rau nruab, sai rau kev tsim, thiab pheej yig, tab sis muaj kev zoo nkauj tsis zoo thiab txwv qhov siab. Cov kav hlau txais xov mounts tuaj yeem ua kom haum rau ntau tus kav hlau txais xov thiab siv tau yooj yim, tab sis muaj kev zoo nkauj tsis zoo thiab qhov siab tsawg.
