Dulmarka Rebar
Rebar waxaa caadi ahaan loo yaqaan bar feeraha duuban oo kulul. Darajada birta duuban ee kulul ee caadiga ah waxay ka kooban tahay dhibicda ugu yar ee HRB iyo darajada. H, R iyo B waa xarfaha ugu horreeya ee duuban kulul, Ribbed iyo Baars siday u kala horreeyaan. Rebar waxaa loo qaybin karaa saddex qaybood iyadoo loo eegayo xoogga:HRB300E, HRB400E, HRB500E, HRB600E, iwm.
Baaxadda tilmaanta dunta ee rebar guud ahaan waa 6-50mm. Waxaan inta badan ku lug leh in ka badan waa 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm iyo wixii la mid ah. Weecsanaanta qaranka ee la ogol yahay: 6-12mm leexashada ± 7%, 14-20mm leexashada ± 5%, 22-50mm weecis ± 4%. Guud ahaan, dhererka go'an ee rebar waa 9m iyo 12m, kuwaas oo ka mid ah 9m dun dun inta badan loo isticmaalo dhismaha caadiga ah wadada iyo 12m dun dheer inta badan loo isticmaalo dhismaha buundada.

| Dusha la dhameeyay | Duubka dunta, dahaarka Epoxy, daahan galvanized |
| Habka wax soo saarka | Rebar waa bir bir ah oo leh dusha feeraha, sidoo kale loo yaqaan xoojinta feeraha, badiyaa leh 2 feeraha dhaadheer iyo feeraha leexsan oo siman oo loo qaybiyay jihada dhererka. Qaabka feeraha leexsan waa qaab wareegsan, qaabka laf dhabarta iyo qaabka bisha. Marka la eego milimitirka dhexroorka magaca ah. Dhexroorka magaca ah ee xoojinta feeraha waxay la mid tahay dhexroorka magaca ah ee xoojinta iftiinka-wareega leh isla qaybta iskutallaabta. Dhexroorka magaca birta birta waa 8-50 mm, dhexroorka lagu taliyayna waa 8, 12, 16, 20, 25, 32 iyo 40 mm. Baararka jeexan inta badan waxay wataan culeyska cufan ee shubka ah. Birta feeraha leh waxay si fiican u qaadi kartaa ficilka xoogga dibadda sababtoo ah saameynta feeraha iyo shubka. Baararka feeraha waxaa si weyn loogu isticmaalaa dhismayaal kala duwan, gaar ahaan kuwa waaweyn, kuwa culus, kuwa derbiyada khafiifka ah iyo kuwa dhaadheer. |

| Codsiga | Rebar waxaa si weyn loogu isticmaalaa dhismaha, buundada, waddooyinka iyo dhismayaasha kale ee injineernimada madaniga ah. Laga soo bilaabo jidka weyn, jidka tareenka, buundada, biyo-mareenka, tunnel, xakamaynta daadadka, biyo-xireenka iyo xarumaha kale ee dadweynaha, ilaa aasaaska dhismaha, alwaaxyada, tiirarka, darbiyada, taarikada, birta birta ah ayaa lagama maarmaan u ah qalab dhismeed. Iyada oo sii qoto dheeraysa magaalaynta Shiinaha, baahida loo qabo rebar ayaa ku xoogan dhismaha kaabayaasha iyo kobcinta horumarka hantida maguurtada ah. |
