Isiphelo sesiphelo ngokuyintloko silandela i-AASHTO M180, GB-T 31439.1-2015 kunye ne-EN1317 standard.
Izinto eziphathekayo zezona zinto ziyi-Q235B (i-S235Jr amandla emveliso ingaphezu kwe-235Mpa) kunye ne-Q345B (S355Jr amandla okuvelisa ngaphezu kwe-345Mpa).
Kubunzima besiphelo setheminali ikakhulu nge-2.5mm ukuya kwi-4.0mm okanye ulandele imfuno yabathengi.
Unyango lwangaphezulu lushushu lufakwe igalvanized, ukulandela i-AASHTO M232 kunye nomgangatho olinganayo njenge-AASHTO M111, EN1461 njl.
Isiphelo setheminali similiselwe ekuqaleni nakwisiphelo sendlela.Inokukhusela abantu ngepleyiti yentsimbi egobileyo, ukuthoba inxeba elisuka kumlindi.
