SS400 waxaa badanaa lagu rogaa gariirad ama bir wareegsan,xaashi bir ah oo kulul ss4oobir afar gees ah, bir siman,xagal birta ss4oo, I-beam, birta kanaalka, birta daaqada iyo qaababka kale ee birta, iyo saxan bir dhexdhexaad ah.Tiro badan oo codsiyo ah oo ku saabsan qaab dhismeedka dhismaha iyo injineernimada.Loo isticmaalo in lagu sameeyo xoojinta birta ama dhismaha dhirta iyo armaajooyinka, munaaradaha gudbinta korantada sare, buundooyinka, baabuurta, kuleyliyaha, weelasha, maraakiibta, iwm, sidoo kale loo isticmaalo tiro badan oo ah shuruudaha waxqabadka ma aha qaybo farsamo oo aad u sarreeya;C, birta-D-fasalka sidoo kale waxaa loo isticmaali karaa qaar ka mid ah birta gaarka ah.
1, muunad saxan bir ah oo 16mm ah, awoodda wax-soosaarka saxanka birta ee SS400 waa 10Mpa ka sarreeya xoogga dhalidda Q235A.
2, Xoog xajin iyo dhererka ayaa ka sarreeya Q235A.
3, SS400 saxan bir ah ayaa ku habboon buundooyinka, maraakiibta, iyo baabuurta, saxan Q235A waa ka cidhiidhsan SS400.
Saxanka birta SS400 waa inuu lahaadaa noocyo kala duwan oo waxqabad tayo sare leh, isticmaalka geeddi-socodku sidoo kale waa mid aad u fiican, sidaa darteed inta badan isticmaaleyaasha ayaa si wada jir ah u ammaanay oo lagu aqoonsaday warshadaha wax soo saarka, isticmaalka joogtada ah iyo soo-saareyaasha ayaa sii wadey kor u qaadista iyo cusboonaysiinta, oo si tartiib tartiib ah SS400 birta waxay noqotay mid ka mid ah darajooyinka saxanka birta ee inta badan laga isticmaalo dalka.
