Zomangira mafakitale amapangidwa akalumikidzidwa zosiyanasiyana ndi standards.Zitsulo kaloti ali ndi luso mkulu kwambiri kuyimitsa kupsyinjika mkulu kwambiri mchikakamizo cha kutentha mankhwala, kutsogolera kusankha aloyi izi pamene kubala mabawuti zitsulo ntchito mu mafakitale structures.Ferroalloy zitsulo ndi amtengo wapamwamba Kuwonjezera okhutira ndi apamwamba kwambiri kuposa chitsulo koyera, amene ndi ofewa kwambiri. sulfure, phosphorous, ndipo nthawi zina ngakhale vanadium (vanadium imawonjezeredwa kuzinthu zachitsulo zomwe zimafuna elasticity) zimapezeka muzitsulo zachitsulo.
Mu zomangamanga, mabawuti structural ndi mtedza chimagwiritsidwa ntchito kupanga sheds, milatho, madamu ndi zomera mphamvu. Ndipotu, kugwiritsa ntchito mabawuti structural ndi mtedza wachita alternately ndi kuwotcherera zitsulo, kutanthauza mwina structural mabawuti kapena arc kuwotcherera ntchito maelekitirodi, malinga ndi kufunika kujowina zitsulo mbale ndi kukhala disaamed kugwirizana kwake ndi zitsulo kugwirizana. zomwe tikambirana pansipa.
Zomangira zomangira zomwe zimagwiritsidwa ntchito popanga zolumikizira zimapangidwa ndi chitsulo chapamwamba kwambiri, kalasi ya 10.9.Grade 10.9 zikutanthauza kuti mphamvu yamakomedwe ya wononga zomangira ndi pafupifupi 1040 N/mm2, ndipo imatha kupirira mpaka 90% ya kupsinjika kwathunthu komwe kumagwiritsidwa ntchito ku wononga thupi m'dera lopanda zotanuka, chitsulo chowuma 4.6, chitsulo chowuma 4.6. zomangira zomangira zimakhala ndi mphamvu zolimba kwambiri ndipo zimakhala ndi chithandizo cha kutentha chovuta kwambiri popanga.
Mosiyana ndi muyezo muyezo hexagon mabawuti ndi mtedza, muyezo hexagon mabawuti ndi mtedza amapangidwa molingana ndi DIN931 muyezo monga magiya theka, malinga DIN933 muyezo monga magiya zonse, ndi zomangira hexagonal n'zosavuta, kawirikawiri amapangidwa molingana ndi DIN6914 standard.Kuphatikizira mtedza pa structural zomangira 3 ndi zomangira apamwamba kuposa DIN9 zomangira apamwamba ndi 9 zomangira 9 zomangira thupi ndi zambiri DIN933 zomangira ndi 933 mlingo wapamwamba kwambiri. kukana maganizo, opangidwa kwa DIN6915.Zomangira za zomangamangazi zimalembedwa 10HV ndipo nthawi zambiri zimakhala zakuda zakuda za matt phosphating kuti zitheke kukana dzimbiri zachilengedwe kapena kuviika kotentha kokhala ndi malata kapena siliva wa chrome matt, onse okhala ndi zitsulo zachitsulo.
