Tuubooyinka qaybta bannaan ee labajibbaaran iyo leydi leh ee laga sameeyay birta khafiifka ah ee Q235 ayaa inta badan loo adeegsadaa dhismaha dhismaha, qaab-dhismeedka taageerada, iyo codsiyada qaab-dhismeedka. Tuubooyinkan waxaa lagu yaqaanaa adkeysigooda, sahlanaanta wax-soo-saarka, iyo ku habboonaanta alxanka iyo hababka samaynta kala duwan. Magacaabista Q235 waxay muujinaysaa in birta laga sameeyay birta kaarboonka fudud.
