MS Flat Bar / Carbon Steel Flat Bar / Amashanyarazi ashyushye Flat Bar
1. Ibicuruzwa bidasanzwe.Umubyimba ni 8 ~ 50mm, ubugari ni 150-625mm, uburebure ni 5-15m, naho ibicuruzwa bisobanurwa ni byinshi, bishobora guhuza ibyo abakoresha bakeneye.Irashobora gukoreshwa mu buryo butaziguye aho kuba isahani yo hagati idakatiye kandi irashobora gusudwa mu buryo butaziguye.
2. Ubuso bwibicuruzwa biroroshye.Amazi yumuvuduko ukabije wamazi akoreshwa inshuro ebyiri murwego rwo kureba ko hejuru yicyuma cyoroshye kandi gifite isuku.
3. Impande zirahagaritse, kandi rhomboide irasobanutse.Ibirindiro byombi bihagaritse kurangiza kuzenguruka byemeza neza ko bihagaze neza kumpande zombi, impande zisobanutse, hamwe nubuziranenge bwubuso kumpande.
4. Ingano yibicuruzwa nukuri, itandukaniro ryamanota atatu, itandukaniro ryurwego rumwe riruta icyuma cyerekana icyuma;ibicuruzwa biragororotse kandi imiterere ni nziza.Kurangiza kuzunguruka bifata inzira ikomeza yo kuzunguruka hamwe no kugenzura byikora byikora kugirango harebwe niba nta cyuma kirundanye kandi nta cyuma gikururwa.Igicuruzwa gifite uburebure buhanitse.Urwego rwo kwihanganira, gutandukanya ingingo eshatu, itandukaniro rimwe, gutandukanya umuhoro, nibindi bipimo biruta isahani yo hagati.Urwego rwiza.Gukata ubukonje, gukata neza muburebure.
5. Ibikoresho byibicuruzwa byemeza ubuziranenge bwigihugu, bingana nicyapa.Ibipimo byiza na tekiniki byateguwe ukurikije ibipimo bya YB / T4212-2010 (Q345B / Q235B bivuga GB / T1591-94 na GB / T700-06)
