Chidule cha Rebar
Rebar imadziwika kuti hot rolled ribbed bar. Giredi ya bar yachitsulo chotentha chokhazikika imakhala ndi mfundo yocheperako ya HRB ndi giredi. H, R ndi B ndi zilembo zoyamba za hot rolled, Ribbed ndi Bars motsatana. Rebar ikhoza kugawidwa m'magulu atatu malinga ndi mphamvu: HRB300E, HRB400E, HRB500E, HRB600E, ndi zina zotero.
Mtundu wa ulusi wa rebar nthawi zambiri umakhala 6-50mm. Nthawi zambiri timagwiritsa ntchito zambiri monga 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm ndi zina zotero. Kupatuka kovomerezeka kwa dziko lonse: kupatuka kwa 6-12mm mu ±7%, kupatuka kwa 14-20mm mu ±5%, kupatuka kwa 22-50mm mu ±4%. Kawirikawiri, kutalika kokhazikika kwa rebar ndi 9m ndi 12m, pakati pawo ulusi wautali wa 9m umagwiritsidwa ntchito makamaka pomanga misewu wamba ndipo ulusi wautali wa 12m umagwiritsidwa ntchito makamaka pomanga mlatho.

| Pamwamba Patha | Ulusi wokulungidwa, Epoxy wokutira, Galvanized wokutira |
| Njira Yopangira | Rebar ndi chitsulo chokhala ndi pamwamba pa ribbed, chomwe chimadziwikanso kuti ribbed reinforcement, nthawi zambiri chimakhala ndi nthiti ziwiri zazitali komanso nthiti yopingasa yogawidwa mofanana kutalika kwake. Mawonekedwe a nthiti yopingasa ndi mawonekedwe ozungulira, mawonekedwe a herringbone ndi mawonekedwe a crescent. Ponena za mamilimita a mainchesi odziwika. M'mimba mwake wa ribbed reinforcement ndi wofanana ndi mainchesi odziwika a reinforcement yozungulira yozungulira yokhala ndi gawo lomwelo. M'mimba mwake wa chitsulo ndi 8-50 mm, ndipo mainchesi ofunikira ndi 8, 12, 16, 20, 25, 32 ndi 40 mm. Mipiringidzo yokhala ndi ribbed imanyamula mphamvu yokoka mu konkriti. Mpiringidzo wachitsulo wokhala ndi ribbed ukhoza kupirira mphamvu yakunja bwino chifukwa cha mphamvu ya ribbed ndi konkriti. Mipiringidzo yokhala ndi ribbed imagwiritsidwa ntchito kwambiri m'nyumba zosiyanasiyana, makamaka nyumba zazikulu, zolemera, zopepuka zokhala ndi makoma owonda komanso ataliatali. |

| Kuyendera Njira | Kuyesa kwa ma tensile (1) Njira yoyesera ma tensile: GB/T228.1-2010, JISZ2201, JI SZ2241, ASTMA370, Г О С Т 1497, BS18, etc; (2) Njira yoyesera yopindika: nthawi zambiri amagwiritsa ntchito njira zoyesera zokhazikika monga GB/T232-88, YB/T5126-2003, JISZ2248, ASTME290, ROCT14019, etc. |
| Kugwiritsa ntchito | Rebar imagwiritsidwa ntchito kwambiri pomanga nyumba, milatho, misewu ndi zomangamanga zina. Kuyambira msewu waukulu, njanji, milatho, kalvert, ngalande, njira yowongolera kusefukira kwa madzi, damu ndi malo ena aboma, mpaka maziko a nyumbayo, matabwa, zipilala, makoma, mbale, ndi zitsulo zomangira ndi zinthu zofunika kwambiri. Chifukwa cha kukula kwa mizinda ku China, kufunikira kwa rebar kumakhala kwakukulu pomanga zomangamanga komanso chitukuko cha malo ogulitsa nyumba. |
