Dulmar guud oo ku saabsan Rebar-ka
Rebar waxaa badanaa loo yaqaan hot rolling ribbed bar. Darajada hot rogged steel tubbada caadiga ah waxay ka kooban tahay dhibicda ugu yar ee HRB iyo darajada. H, R iyo B waa xarfaha ugu horreeya ee hot rolling, Ribbed iyo Bars siday u kala horreeyaan. Rebar waxaa loo qaybin karaa saddex qaybood iyadoo loo eegayo xoogga: HRB300E, HRB400E, HRB500E, HRB600E, iwm.
Kala duwanaanshaha qeexitaanka dunta ee rebar-ka guud ahaan waa 6-50mm. Badanaa waxaan ku darnaa in ka badan 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm iwm. Kala duwanaanshaha la oggol yahay ee qaranka: 6-12mm leexasho ±7%, 14-20mm leexasho ±5%, 22-50mm leexasho ±4%. Guud ahaan, dhererka go'an ee rebar-ka waa 9m iyo 12m, kuwaas oo dunta dheer ee 9m inta badan loo isticmaalo dhismaha waddooyinka caadiga ah iyo dunta dheer ee 12m inta badan loo isticmaalo dhismaha buundooyinka.

| Habka Wax Soo Saarka | Rebar waa bir bir ah oo leh dusha sare ee feeraha leh, oo sidoo kale loo yaqaan xoojinta feeraha leh, badanaa leh 2 feeraha dhererka leh iyo feeraha isdhaafka ah si siman ugu qaybsama jihada dhererka. Qaabka feeraha isdhaafka ah waa qaab wareegsan, qaabka lafaha herringbone iyo qaabka bisha. Marka la eego milimitir dhexroorka magacaaban. Dhexroorka magacaaban ee xoojinta feeraha leh wuxuu la mid yahay dhexroorka magacaaban ee xoojinta iftiinka-wareegga leh isla qaybta isgoyska. Dhexroorka magacaaban ee birta birtu waa 8-50 mm, dhexroorka lagu taliyayna waa 8, 12, 16, 20, 25, 32 iyo 40 mm. Baararka feeraha leh waxay inta badan qaadaan cadaadis jiidis ah oo ku jira shubka. Baarka birta feeraha leh wuxuu si fiican u qaadi karaa ficilka xoogga dibadda sababtoo ah saameynta feeraha iyo shubka. Baararka feeraha leh waxaa si weyn loogu isticmaalaa dhismayaasha dhismaha ee kala duwan, gaar ahaan dhismayaasha waaweyn, culus, khafiifka ah ee derbiyada khafiifka ah iyo kuwa dhaadheer. |

| Codsiga | Rebar-ka waxaa si weyn loogu isticmaalaa dhismaha, buundada, waddooyinka iyo dhismayaasha kale ee injineernimada madaniga ah. Laga bilaabo wadada weyn, tareenka, buundada, biyo-mareenka, tunnel-ka, xakamaynta daadadka, biyo-xireenka iyo xarumaha kale ee dadweynaha, ilaa aasaaska dhismaha, alwaaxyada, tiirarka, derbiyada, saxanadaha, birta boolalku waa agab dhisme oo aan lagama maarmaan ahayn. Iyada oo ay sii xoogaysanayso magaalooyinka Shiinaha, baahida loo qabo rebar-ka ayaa aad u xooggan dhismaha kaabayaasha dhaqaalaha iyo horumarka sii kordhaya ee hantida ma-guurtada ah. |
