近几年来,一些地方钢厂生产φ6.5钢筋,而不生产φ6钢筋。我们在施工中,只好用φ6.5钢筋代替,这样就浪费了17%的钢材。建议改生产φ6钢筋。
In recent years, some local steel mills have produced φ6.5 steel bars instead of φ6 steel bars. In construction, we had to replace it with φ6.5 steel, which wastes 17% of the steel. It is proposed to change production of φ6 steel bars.
