Kufotokozera kwa ASTM A615 Reinforceing Bar Giredi 60
ASTM A615 Steel Rebar imawonjezera mphamvu yokoka ya konkire ndipo ingagwiritsidwe ntchito polimbitsa konkire koyamba komanso kwachiwiri. Imathandiza kuyamwa kupsinjika ndi kulemera ndipo imathandizira kufalikira kofanana kwa kupsinjika komwe kumachitika chifukwa cha kukula ndi kupindika kwa konkire ikakumana ndi kutentha ndi kuzizira, motsatana.
ASTM A615 Steel Rebar ili ndi mawonekedwe ozungulira, abuluu-imvi okhala ndi nthiti zokwezedwa mu bar yonse. ASTM A615 Grade 60 Steel Rebar imapereka mphamvu yowonjezera yokolola ya mapaundi osachepera 60,000 pa inchi imodzi, kapena ma megapascal 420 pa sikelo yoyezera. Ilinso ndi dongosolo lopitilira mzere, ndi mzere umodzi womwe ukuyenda motsatira kutalika kwa bar yomwe ili pafupi ndi malo osachepera asanu kuchokera pakati. Makhalidwe amenewa amachititsa kuti Grade 60 Steel Rebar ikhale yoyenera kwambiri kugwiritsa ntchito konkriti yolimba yapakatikati mpaka yolemera.

Kulongedza zitsulo,
Kupaka pulasitiki ndi njira zina zopaka.
Tili okonzeka kulongedza ndi kutumiza zinthu malinga ndi kulemera, zofunikira, zipangizo, ndalama zogulira komanso zosowa za makasitomala.
Tikhoza kupereka mayendedwe a zidebe kapena zonyamula katundu, misewu, njanji kapena njira zina zoyendera zapamtunda kuti titumize kunja. Zachidziwikire, ngati pali zofunikira zapadera, tingagwiritsenso ntchito mayendedwe a pandege.
