Chitsulo chachitsulondi gawo lofunikira pantchito yomanga. Zinthu zosunthikazi zimapereka mphamvu ndi kukhazikika kwa zomanga za konkriti, kuzipangitsa kuti zikhale zolimba komanso zosagwirizana ndi kupsinjika ndi kupsinjika. Amagwiritsidwa ntchito kwambiri pomanga nyumba, milatho, misewu, ndi ntchito zina zomanga.
Rebar yachitsulo imapangidwa ndi chitsulo cha carbon, chomwe ndi alloy yachitsulo ndi carbon. Zinthu zina, monga manganese, silicon, ndi mkuwa, zitha kuwonjezeredwanso kuti zisinthe. Kupanga kumaphatikizapo kugudubuza-kutentha kapena kuzizira zitsulo muzitsulo zazitali, zoonda zamitundu yosiyanasiyana ndi mawonekedwe.
Rebar yachitsulo idatchuka mwachangu chifukwa champhamvu komanso kulimba kwake, zomwe zidapangitsa mainjiniya kupanga zida zazitali komanso zovuta. Masiku ano, rebar yachitsulo ndi chinthu chofunikira kwambiri pantchito yomanga, ndipo kugwiritsidwa ntchito kwake kumayendetsedwa ndi miyezo ndi ma code osiyanasiyana kuti zitsimikizire chitetezo ndi kudalirika.
Chimodzi mwazabwino zazikulu zazitsulo zachitsulo ndi mphamvu yake yolimba kwambiri, zomwe zikutanthauza kuti imatha kupirira kupsinjika kwakukulu popanda kusweka kapena kupunduka. Katunduyu ndi wofunikira kwambiri pamapangidwe a konkriti olimbikitsidwa, pomwe rebar imagwira ntchito ngati kulimbikitsa kukana mphamvu zolimba zomwe konkriti yokhayo siyingathe kupirira. Rebar yachitsulo imakhalanso ndi ductility yabwino kwambiri, kutanthauza kuti imatha kutambasula ndikupindika popanda kusweka, kulola kuti itenge mphamvu kuchokera ku konkire yozungulira panthawi ya zivomezi ndi zochitika zina za zivomezi.
Rebar yachitsulo imabwera mosiyanasiyana ndi mawonekedwe, iliyonse imapangidwira ntchito zinazake. Mitundu yodziwika bwino ya rebar imaphatikizapo plain, deformed, and epoxy-coated rebar. Plain rebar ili ndi malo osalala ndipo nthawi zambiri imagwiritsidwa ntchito pochepetsa nkhawa. Rebar yopunduka, komano, imakhala ndi nthiti, tokhala, kapena zopindika zina pamwamba pake, zomwe zimapereka kugwiritsitsa bwino komanso kumamatira konkriti yozungulira. Rebar yokutidwa ndi epoxy imakhala ndi chotchinga choteteza cha epoxy, chomwe chimalepheretsa dzimbiri ndikukulitsa moyo wa rebar.
Pomaliza, rebar yachitsulo ndi chinthu chofunikira kwambiri pantchito yomanga. Kulimba kwake, kulimba kwake, komanso ductility kumapangitsa kuti ikhale yolimbikitsira bwino zomanga za konkriti. Pogwiritsa ntchito zitsulo zopangira zitsulo, mainjiniya amatha kupanga zida zazitali, zamphamvu, komanso zolimba zomwe zimatha kupirira kupsinjika ndi zovuta zambiri. Pamene ntchito yomanga ikupitabe kukula, zitsulo zopangira zitsulo mosakayikira zidzakhalabe gawo lofunika kwambiri pomanga zomangamanga za mawa.
