I-A36, eyaziwa nangokuthi i-ASTM-A36, iwuhlobo lwensimbi ngaphansi kwe-ASTM evamile yaseMelika enamandla okukhiqiza angu-36KSI (≈250Mpa). Ukuqhathanisa izindinganiso zayo zezakhiwo zomzimba nezamakhemikhali nezinhlobo ezimbalwa ezivamile zensimbi kumazinga asekhaya:

Isifinyezo sokuqhathanisa:

1. Ngenxa yokuthi i-Q235B imelana nomthelela, i-Q235B isetshenziswa esikhundleni sezinto ze-SA36 esakhiweni sensimbi.

2. I-Q235A, ngenxa yokuthi ukusebenza kwempahla akukwazi ukuhlangabezana nezidingo zesitsha sokucindezela, manje i-Q235A ivinjelwe ukusetshenziswa ekukhiqizeni umkhumbi ocindezelayo, okwenza kube nzima ukuthenga i-Q235A emakethe. Ngakho-ke

Ngakho-ke, ngokuvamile kuyanconywa ukuthi esikhundleni se-A36 kufakwe i-Q235B.
