ASTM A572 High Strength Steel Channel

Ko te ASTM A572 he maitai-kaha-iti (HSLA) maitai me te ihirangi koranu o te columbium me te vanadium, e whakakaha ana i te maitai me te whakarato i te kaha ira hua teitei ake i te ASTM A36. A572 HSLA hongere maitai he pai mo nga tono me kaha ake te kaha mo te whakaheke i te matotoru me te taumaha.
