三级钢筋理论分量表螺纹钢筋的分类中,一级螺纹钢筋:其强度等级为24/38公斤级,是用镇静钢、半镇静钢或许沸腾钢3号普通碳素钢轧制的光圆钢筋,也是归于低强度钢筋,具有塑性好、伸长率高、便于弯折成型、简单焊接等特色,它的运用范围也是比较广泛,能够用作中、小型钢筋混凝土结构的首要受力钢筋,构件的箍筋,钢、木结构的拉杆等等,盘条钢筋也是能够作为冷拔低碳钢丝和双钢筋的质料。 二级螺纹钢筋:二级螺纹用低合金镇静钢或许是半镇静钢轧制,以硅、锰作为固溶强化元素,二级钢筋强度等级34/50公斤级,其强度也比较高,塑性比较好,焊接功能比较抱负,钢筋表面轧有一般的纵筋和均匀分布的横肋,然后加强钢筋与混凝土间的粘接。用二级钢筋作为钢筋混凝土结构的受力钢筋,比运用以及钢筋可节约钢材40-50%,因而也广泛的运用在大、中型钢筋混凝土结构。可是从近几年开端二级钢筋现已逐步的退出钢筋商场。 螺纹钢筋的分类中三四级螺纹钢:三四级螺纹钢归于高强度的抗震钢筋,在延展性上有很大的打破,可是在价位上是要高于一二级螺纹钢,现在国家也大力的推行运用高强度的抗震钢筋,三级钢筋理论分量表后期高强度钢筋将彻底的代替二级螺纹钢。
