ASTM A572 steel angle ke likarolo tse ling tsa tšepe tse matla, tse tlase-tlase (HSLA) columbium-vanadium. Ka lebaka la likarolo tse nyane tsa columbium & vanadium alloy, angle e chesang ea A572 e na le thepa e ntle ho feta carbon steel A36. Taba ea pele, A572 e na le matla a phahameng ho feta A36 joalo ka matla a tlhahiso le matla a ho tsitsa. Ea bobeli, ho bonolo ho tjheseletsa, ho theha le mochini.
A572 matla a phahameng a tšepe angle
Li-angles tsa tšepe tse entsoeng ka galvanized & Pre-lacquered
A572 steel angle e na le lisebelisoa tse ngata ka lebaka la karo-karolelano e phahameng ea matla ho boima ba 'mele. Hobane ha e na koporo e thusang ho thibela ho bola, li-angles tsa tšepe tsa A572 hangata li entsoe ka masela a chesang kapa a kentsoeng pele ho lacquered. 'Mala oa ho penta o ho kopo ea hau.
Tlhaloso ea angle ea tšepe ea A572:
Tlhokomeliso: Ho na le litšepe tse khethehileng tse nang le li-angles tse fumanehang haeba palo ea odara ea hau e feta bonyane.
