ASTM A572 steel angle ndi zigawo zina zazitsulo zolimba kwambiri, za low-alloy (HSLA) columbium-vanadium. Chifukwa cha kuchepa kwa zinthu za columbium & vanadium alloy, ngodya yachitsulo ya A572 yotentha imakhala ndi zinthu zabwinoko kuposa carbon steel A36. Choyamba, A572 ili ndi mphamvu zapamwamba kuposa A36 ngati mphamvu zokolola komanso mphamvu zamakokedwe. Chachiwiri, n'zosavuta kuwotcherera, mawonekedwe ndi makina.
A572 mkulu mphamvu zitsulo ngodya
Galvanized & Pre-lacquered zitsulo ngodya
A572 chitsulo angle ili ndi ntchito zambiri chifukwa cha chiŵerengero chachikulu cha mphamvu ndi kulemera. Chifukwa ilibe mkuwa womwe umathandiza kuti zisawonongeke, ma angles achitsulo a A572 nthawi zambiri amakhala ndi malata otentha kapena opaka kale. Mtundu wa penti uli pa pempho lanu.
Kufotokozera kwa ngodya yachitsulo ya A572:
Zindikirani: Kukula kwachitsulo kwapadera kulipo ngati kuchuluka kwa oda yanu kukuposa zochepa.
