圆钢是指截面为圆形的实心长条钢材。其规格以直径的毫米数表示,如“50”即表示直径为50毫米的圆钢。圆钢分为热轧、断指和冷拉三种。热轧圆钢的规格为5.5-250毫米。其中5.5-25毫米的小圆钢大多以直条成捆供应,常用作钢筋、螺栓及各种机械零件;大于25毫米的圆钢,主要用于制造机械零件或作无缝钢管坯。
圆钢与其它钢筋的区别:1 外型不一样,圆钢外型光圆,无纹无肋,其它钢筋表面外型有刻纹或有肋,这样就造成圆钢与混凝土的粘结力小,而其它钢筋与混凝土的粘结力大。 2 成份不一样,圆钢(*钢)属于普通低碳钢,其它钢筋多为合金钢。3强度不一样,圆钢强度低,其它钢强度高,即直径大小相同的圆钢与其它钢筋相比,圆钢所能承受的拉力要比其它钢筋小,但圆钢的塑性比其它钢筋强,即圆钢在被拉断前有较大的变形,而其它钢筋在被拉断前的变形要小得多。
