Ntchito yayikulu: imagwiritsidwa ntchito kwambiri pomanga zomangamanga monga nyumba, milatho, misewu, ndi zina.
Kusiyana pakati pa rebar ndi bar yozungulira: Kusiyana pakati pa rebar ndi bar yozungulira ndikuti pali nthiti zazitali ndi nthiti zopingasa pamwamba, nthawi zambiri zimakhala ndi nthiti ziwiri zazitali ndi nthiti zopingasa zomwe zimagawidwa molingana ndi kutalika kwake.Rebar ndi gawo laling'ono lachitsulo, lomwe limagwiritsidwa ntchito makamaka popanga zigoba zomangira konkriti.Pogwiritsidwa ntchito, mphamvu zina zamakina, kupindika kwa mapindikidwe ndi magwiridwe antchito amafunikira.Zopangira zopangira ma rebars ndi chitsulo chopangidwa ndi kaboni kapena chitsulo chochepa cha alloyed chomwe chimapangidwa ndi sedation.
Zitsulo zomangika, zitsulo zomalizidwa zimaperekedwa m'malo otentha, okhazikika kapena otenthedwa.

Pali njira ziwiri zomwe zimagwiritsidwa ntchito pogawa rebar;imodzi imagawidwa ndi mawonekedwe a geometric, ndipo imagawidwa kapena kuikidwa molingana ndi mawonekedwe apakati a nthiti yodutsa ndi katalikirana ka nthiti.
Mtundu, monga British Standard (BS4449), rebar imagawidwa kukhala |type, ndikulemba.Kugawika uku kumawonetsa kwambiri magwiridwe antchito a rebar.Awiri ndi
Gulu la magwiridwe antchito (kalasi), monga momwe dziko langa likugwiritsidwira ntchito pano, rebar ndi (GB1499.2-2007) waya ndodo ndi 1499.1-2008), kutengera mphamvu giredi
Zosiyana (zokolola zokolola / mphamvu zamakokedwe), rebar imagawidwa m'magulu atatu;mu Japan Industrial Standard (JISG3112), rebar imagawidwa m'mitundu 5 malinga ndi magwiridwe antchito;mu British Standard (BS4461), rebar imatchulidwanso Magawo angapo oyesa magwiridwe antchito.Kuphatikiza apo, rebar imathanso kukonzedwa molingana ndi kugwiritsa ntchito.
Gulu, monga mipiringidzo wamba zitsulo zolimbitsa konkire ndi zitsulo zotenthetsera kutentha kwa konkire yokhazikika.
