Isishwankathelo seRebar
I-Rebar yaziwa kakhulu ngokuba yi-hot rolled ribbed bar. Uhlobo lwe-hot rolled steel bar eqhelekileyo luqulathe i-minimum yield point ye-HRB kunye nohlobo. I-H, i-R kunye ne-B ziileta zokuqala ze-hot rolled, i-Ribbed kunye ne-Bars ngokwahlukeneyo. I-Rebar ingahlulwahlulwa ibe ziindidi ezintathu ngokobukhulu: HRB300E, HRB400E, HRB500E, HRB600E, njl.
Uluhlu lweenkcazo zemisonto ye-rebar ngokubanzi yi-6-50mm. Sidla ngokubandakanya ezingaphezulu yi-8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm njalo njalo. Ukuphambuka okuvumelekileyo kuzwelonke: ukuphambuka kwe-6-12mm kwi-±7%, ukuphambuka kwe-14-20mm kwi-±5%, ukuphambuka kwe-22-50mm kwi-±4%. Ngokubanzi, ubude obumiselweyo be-rebar yi-9m kunye ne-12m, phakathi kwazo intambo ende ye-9m isetyenziselwa kakhulu ukwakhiwa kwendlela eqhelekileyo kwaye intambo ende ye-12m isetyenziselwa kakhulu ukwakhiwa kwebhulorho.

| Umphezulu ugqityiwe | Intambo yesikrufu, i-Epoxy coating, i-Galvanized coating |
| Inkqubo yeMveliso | I-Rebar yintsimbi enomphezulu oneembambo, okwaziwa ngokuba yi-ribbed reinforcement, idla ngokuba neembambo ezimbini ezinde kunye ne-transverse rib esasazwe ngokulinganayo kwicala lobude. Imilo ye-transverse rib yi-spiral shape, i-herringbone shape kunye ne-crescent shape. Ngokweemilimitha zobubanzi obuqhelekileyo. Ububanzi obuqhelekileyo bokuqinisa i-ribbed bulingana nobubanzi obuqhelekileyo bokuqinisa ukukhanya okujikelezileyo okune-cross-section efanayo. Ububanzi obuqhelekileyo be-steel bar yi-8-50 mm, kwaye ububanzi obucetyiswayo yi-8, 12, 16, 20, 25, 32 kunye ne-40 mm. Ii-ribbed bar zithwala uxinzelelo lokuxinana kwikhonkrithi. I-ribbed steel bar inokuthwala isenzo samandla angaphandle ngcono ngenxa yesiphumo se-ribbed kunye nekhonkrithi. Ii-ribbed bar zisetyenziswa kakhulu kwizakhiwo ezahlukeneyo zezakhiwo, ngakumbi izakhiwo ezinkulu, ezinzima, ezikhaphukhaphu nezinde. |

| Isicelo | I-Rebar isetyenziswa kakhulu ekwakheni, kwiibhulorho, ezindleleni nakwezinye izakhiwo zobunjineli bokwakha. Ukusuka kwindlela enkulu, koololiwe, kwiibhulorho, kwiikhalvethi, kwiitonela, kwiilayini, kwiilayini zokulawula izikhukula, kwiidama nakwezinye izakhiwo zikawonke-wonke, ukuya kwisiseko sesakhiwo, iibhari, iintsika, iindonga, iipleyiti, neentsimbi zesikrufu zizinto zokwakha eziyimfuneko. Ngokukhula kwesixeko saseTshayina, imfuno ye-rebar inamandla ekwakheni iziseko zophuhliso kunye nophuhliso olukhulayo lwezindlu nomhlaba. |
