Raupapa S235, S275, me S355ko ngā tohu e tino tohua ana, ia tohu e whakatutuki ana i ngā hiahia hanganga motuhake:

Pereti maitai hurihuri wera S235JR/J0/J2, me te kaha whakaputa iti rawa o te 235 MPa, e whakamahia whānuitia ana i roto i ngā hanganga maitai whānui, ngā kurupae whare, ngā pou, me ngā turanga miihini. Nā tōna kaha whakarewa me te whai huatanga utu ka rite ki te ASTM A36, inā koa i roto i ngā kaupapa arumoni me ngā kaupapa ahumahi māmā.

Pereti maitai S275JR/J0/J2he kaha ake, he pai tonu te mahi tukatuka. He mea whakamahi noa i roto i ngā piriti, ngā mīhini hangarau, me ngā wāhanga e kawe ana i te kawenga waenga.

Pereti maitai waro S355JR/J0/J2/K2, e mōhiotia whānuitia ana ko te taumata kaweake matua, e tuku ana i te kaha hua iti rawa o te 355 MPa me te pakari teitei. E whakamahia whānuitia ana tēnei taumata i roto i ngā hanganga maitai taumaha, te hangarau piriti, ngā papaaho moana, me ngā pourewa hiko hau, ā, he maha ngā wā ka tohua hei huarahi kē atu ki te ASTM A572 Grade 50, ASTM A992 rānei.
