BS EN 10210 S275J0Hndi otentha-anamaliza dzenje structural zitsulo gawo chopangidwa kutiMtengo wa EN 10210mumitundu yosiyanasiyana yozungulira, masikweya, amakona anayi kapena oval.
Zinthu za S275J0H zimadziwika ndi mphamvu zochepa zokolola za 275 MPa pa makulidwe osapitirira 16 mm;mphamvu zake zocheperako ndizochepera 27 J pa 0 ℃.
S275J0H ndi yamtundu wa chitsulo cha carbon, nambala yachitsulo1.0149, yomwe ili ndi mapangidwe abwino komanso opangira zinthu, omwe amagwiritsidwa ntchito kwambiri pomanga nyumba, komanso amagwiritsidwa ntchito pazinthu zopanda katundu, akhoza kupereka posungira kukhazikika kwapangidwe ndi kukhazikika potengera kukwaniritsidwa kwa phindu lotsika mtengo.
Chidziwitso: Zofunikira zonse mu BS EN 10210 zimagwiranso ntchito ku EN 10210 ndipo chifukwa chake sizibwerezedwa apa.

Timakhala okhazikika popereka mafotokozedwe osiyanasiyana a Round Hollow Structural Steel Pipe, ngati muli ndi zosowa, chonde omasuka kulumikizana nafe, tikuyembekezera kugwirizana nanu!
Muyezo wa BS EN 10210 umalola kuti njira zingapo zopangira zigwiritsidwe ntchito popanga magawo opanda kanthu, kuphatikiza njira zopanda msoko komanso zowotcherera.Mkati mwa kuwotcherera, njira zodziwika bwino zimaphatikizapoMtengo wa LSAW(SAWL), SSAW (Mtengo wa HSAW), ndiERW.
