Ukubuka konke kwe-Rebar
I-Rebar ijwayele ukubizwa nge-hot rolled ribbed bar. Ibanga lensimbi evamile egoqiwe eshisayo liqukethe iphuzu elincane le-HRB nebanga. U-H, R kanye no-B yizinhlamvu zokuqala ze-hot rolled, Ribbed kanye namaBars ngokulandelana. I-Rebar ingahlukaniswa ngezigaba ezintathu ngokwamandla: HRB300E, HRB400E, HRB500E, HRB600E, njll.
Uhla lokucaciswa kochungechunge lwe-rebar ngokuvamile luyi-6-50mm. Ngokuvamile sihilela okwengeziwe 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm nokunye. Ukuchezuka okuvunyelwe kuzwelonke :6-12mm ukuchezuka ku-±7%, ukuchezuka okungu-14-20mm ku-±5%, ukuchezuka okungu-22-50mm ku-±4%. Ngokuvamile, ubude obunqunyiwe be-rebar bungu-9m kanye no-12m, phakathi kwawo intambo ubude obuyi-9m isetshenziselwa ikakhulukazi ukwakhiwa komgwaqo ojwayelekile futhi intambo ende eyi-12m isetshenziselwa ukwakhiwa kwebhuloho.
Ukucaciswa kwe-Rebar
| Igama Lomkhiqizo | Ibha Yensimbi Yokuqiniswa Kwempahla Yokwakha Eyonakele |
| Okubalulekile | HRB335, HRB400, HRB500, JIS SD390,SD490,SD400; GR300,420,520;ASTM A615 GR60;BS4449 GR460,GR500 |

| Ubuso Buqediwe | I-Screw-thread, i-epoxy coating, i-galvanized coating |
| Inqubo Yokukhiqiza | I-Rebar iyibha yensimbi enezimbambo ezingaphezulu, eyaziwa nangokuthi i-ribbed reinforcement, imvamisa enezimbambo ezi-2 ze-longitudinal kanye nezimbambo eziphambeneyo ezisatshalaliswa ngokulinganayo ohlangothini lobude. Ukuma kwe-rib transverse shape spiral shape, herringbone shape kanye ne-crescent shape. Ngokuya ngamamilimitha obubanzi obujwayelekile. Ububanzi obujwayelekile bokuqiniswa kwe-ribbed bulingana nobubanzi obujwayelekile bokuqiniswa okujikelezayo okukhanyayo nge-cross-section efanayo. Ububanzi obujwayelekile bebha yensimbi bungu-8-50 mm, futhi ububanzi obunconywayo bungu-8, 12, 16, 20, 25, 32 no-40 mm. I-ribbed steel bar ingathwala isenzo samandla angaphandle kangcono ngenxa yomphumela we-ribbed kanye nokhonkolo. Imigoqo enezimbambo isetshenziswa kakhulu ezakhiweni ezahlukene zokwakha, ikakhulukazi izakhiwo ezinkulu, ezisindayo, ezilula ezinodonga oluncane nezinde. |

| Isicelo | I-Rebar isetshenziswa kabanzi ekwakheni, ebhulohweni, emgwaqeni nakwezinye izakhiwo zobunjiniyela bomphakathi. Kusukela kuthelawayeka, ujantshi, ujantshi, ibhuloho, umhubhe, ukulawulwa kwezikhukhula, idamu nezinye izinsiza zomphakathi, kuya esisekelweni sesakhiwo, imishayo, amakholomu, izindonga, amapuleti, izikulufu zensimbi yizinto zokwakha ezibalulekile. Ngokudlondlobala kokukhula kwezindawo zasemadolobheni zaseChina, isidingo se-rebar siqinile ekwakhiweni kwengqalasizinda kanye nentuthuko ekhulayo yezindawo ezithengiswayo. |
