Isishwankathelo seRebar
I-Rebar yaziwa ngokuba yi-ribbed bar eshushu. Ibakala lentsimbi eqhelekileyo eshushu eqengqelekayo iqulathe eyona ndawo isezantsi yesivuno seHRB kunye nebakala. H, R kunye no-B ngoonobumba bokuqala be-hot rolled, i-Ribbed kunye neeBars ngokulandelelanayo. I-Rebar inokohlulwa ibe ngamacandelo amathathu ngokwamandla: HRB300E, HRB400E, HRB500E, HRB600E, njl.
Uluhlu lwenkcazo yentambo ye-rebar ngokubanzi yi-6-50mm. Sidla ngokubandakanya ngakumbi 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm njalo njalo. Ukutenxa okuvumelekileyo kuzwelonke :6-12mm ukutenxa kwi-±7%, 14-20mm ukutenxa kwi-±5%, 22-50mm ukutenxa kwi-±4%. Ngokuqhelekileyo, ubude obumiselweyo be-rebar yi-9m kunye ne-12m, phakathi kwayo i-9m ubude bentambo isetyenziselwa ukwakhiwa kwendlela eqhelekileyo kunye ne-12m ubude bentambo isetyenziselwa ukwakhiwa kwebhulorho.

| Umphezulu Ugqityiwe | I-Screw-thread, i-epoxy coating, i-galvanized coating |
| Inkqubo yeMveliso | I-Rebar yintsimbi yentsimbi enomphezulu oyimbambo, ekwabizwa ngokuba yi-ribbed reinforcement, ihlala ineembambo ezi-2 zobude kunye nembambo enqamlezileyo isasazwe ngokulinganayo kwicala lobude. Ubume bembambo ezinqamlezileyo bubume be-spiral, i-herringbone shape kunye ne-crescent shape. Ngokumalunga neemilimitha zedayamitha yegama. Umthamo oqingqiweyo wokuqiniswa kwe-ribbed ulingana nomlinganiselo oqhelekileyo wokuqiniswa kokukhanya okujikelezayo kunye necandelo elifanayo. I-diameter ebizwa ngokuba yintsimbi yentsimbi yi-8-50 mm, kwaye i-diameter ekhuthazwayo yi-8, 12, 16, 20, 25, 32 kunye ne-40 mm. Imivalo ye-Ribbed ithwele uxinzelelo lwe-tensile kwikhonkrithi. I-ribbed steel bar inokuthwala isenzo samandla angaphandle ngcono ngenxa yempembelelo ye-ribbed and concrete. Imivalo ye-Ribbed isetyenziswa ngokubanzi kwizakhiwo ezahlukeneyo zokwakha, ngakumbi izakhiwo ezinkulu, ezinzima, ezikhanyayo ezinodonga oluncinci kunye nezakhiwo ezide. |

| Isicelo | I-Rebar isetyenziswa ngokubanzi kwisakhiwo, ibhulorho, indlela kunye nolunye ulwakhiwo lobunjineli boluntu. Ukusuka kuhola wendlela, umgaqo kaloliwe, ibhulorho, ikholveti, itonela, ulawulo lwezandyondyo, idama kunye nezinye izibonelelo zikawonke-wonke, ukuya kwisiseko sesakhiwo, imiqadi, iintsika, iindonga, iipleyiti, intsimbi yesikrufu zizinto eziyimfuneko kakhulu zokwakha. Ngokuya kukhula kwedolophu yaseTshayina, imfuno yerebar yomelele kulwakhiwo lweziseko ezingundoqo kunye nophuhliso olukhulayo lwezindlu nezindlu. |
