ASTM A285 Fasalka A saxan bir kululeeyaha ah

Heerka ASTM A285 waxaa loogu talagalay birta kaarboon, taarikada birta ee hooseeya iyo dhexdhexaadka ah ee loogu talagalay weelasha cadaadiska welded.

Saxanka birta ee hoos yimaada ASTM A285 wuxuu u dhexeeyaa saddex darajo, A, B iyo C, isticmaalka ugu badan waa ASTM A285 taarikada darajada C.
Kaas oo lagu samayn doono wax la dilo, la dilay, qaar la dilay, koofiyado ama bir la jeexjeexay marka la eego ikhtiyaarka soo saaraha.

Dhumucda: 6MM ilaa 300MM,
Ballaca: 1500mm ilaa 4050mm,
Dhererka: 3000mm ilaa 15000mm
