Thaum cov txheej txheem steel puas lawm, qhov teeb meem yuav tsum tau pom thiab daws tam sim ntawd. Cov laj thawj tseem ceeb ntawm kev puas tsuaj steel hlau yog raws li hauv qab no:
1) Kev hloov pauv, kev siv sijhawm dhau sijhawm, kev hloov pauv hauv cov qauv thiab cov qauv kev coj ua tsis txaus
2) Cov khoom yog deformed, twisted, obstructed thiab kev nyuaj siab vim muaj ntau yam xwm txheej, seem seem yuav qaug zog, qhov chaw warpage, kev sib txuas rupture thiab lwm yam
3) Qhov sib txawv ntawm qhov kub thiab txias ua rau cov khoom siv los yog kev sib txuas deformation, tawg thiab warpage
4) Vim yog tshuaj lom neeg corrosion thiab electrochemical corrosion, ntu ntu ntawm cov qauv hlau tsis muaj zog
5) Lwm tus suav nrog kev ua yuam kev hauv kev npaj, tsim khoom, kev tsim kho thiab kev siv tsis raug cai thiab kev ua haujlwm thaum siv.
Muaj peb lub ntsiab kev ntsuas rau steel qauv engineering reinforcement:
1) seem ntxiv dag zog rau txoj kev: ib feem lossis raws tag nrho qhov ntev ntawm cov khoom nrog steel ntxiv dag zog, txuas rau tag nrho cov quab yuam
2) Hloov daim duab qhia yooj yim: ntxiv kev txhawb nqa ntxiv, kho cov khoom xa tawm, txo cov theem ntawm lub zog sab hauv, quab yuam cov qauv kev txiav txim siab tsis tu ncua, txo qhov kev ntxhov siab siab.
3) Prestressed cable txoj kev: siv lub siab zog cable los ntxiv dag zog rau qhov tsis muaj zog txuas ntawm cov qauv, txhim kho tag nrho cov kabmob muaj peev xwm, rigidity thiab stability ntawm cov qauv.
