* Cov tsos yog txawv. Qhov saum npoo ntawm threaded steel muaj kauv ribs, thaum lub ntsej muag ntawm cov hlau puag ncig nthuav qhia ib qho kev sib tw hla ntu.
* Ntau qhov sib txawv. Lub zog ntawm threaded steel yog siab dua li ntawm round steel. Lub zog tsim ntawm threaded steel feem ntau yog 300MPa (HRB335 qib) thiab 360MPa (HRB400 qib), thaum lub zog tsim ntawm cov hlau puag ncig feem ntau yog 210MPa (HPB235 qib).
* Cov tshuaj muaj pes tsawg leeg sib txawv. Ntsia hlau xov hlau feem ntau yog ua los ntawm cov hlau tsis tshua muaj hlau, muaj cov ntsiab lus alloying xws li manganese thiab silicon, thaum cov hlau puag ncig yog tsim los ntawm cov hlau uas muaj cov tshuaj lom neeg yooj yim.
* Cov ntawv thov sib txawv. Vim nws lub zog siab thiab kev sib raug zoo nrog cov pob zeb, rebar yog dav siv nyob rau hauv cov khoom siv ntxiv dag zog rau kev tsim cov kav ntev ntev, stirrups, thiab lwm yam, thaum cov hlau puag ncig tsis muaj zog thiab feem ntau yog siv rau kev tsim cov khoom siv kho tshuab thiab cov khoom siv hauv tsev yooj yim, los yog ntxiv. ua tiav rau hauv rebar.
Hauv cov ntsiab lus, kev xaiv cov hlau yog nyob ntawm qhov tshwj xeeb daim ntawv thov scenario thiab yuav tsum tau ua. Rau cov xwm txheej uas xav tau lub zog siab thiab zoo adhesion, threaded steel yog ib qho kev xaiv zoo dua, thaum lub sijhawm tsis xav tau lub zog siab lossis xav tau kev ua haujlwm yooj yim, cov hlau puag ncig yog qhov tsim nyog dua.
