Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob yog tsim los ntawm siab -tensile Q345B carbon steel nrog lub zog tawm ntawm 345 MPa kom tiv taus qhov ntev ntev thiab ntsug loads ntawm ntau pua kilonewtons. Txhua tus tswv cuab ntawm cov txheej txheem tau dhau los ua qhov kub-dip galvanization txheej txheem (ISO 1461), siv cov zinc txheej ntau tshaj 86μm rau kev saib xyuas- pub dawb lub neej ntawm 50 txog 100 xyoo.
