The news of the discontinuation of the production of secondary reinforcement has been released for a long time. From the current implementation situation, the use of secondary reinforcement has been stopped in most areas of the country, but there are still small areas using secondary reinforcement. Therefore, the current implementation effect of the discontinuation of production of secondary reinforcement still needs a period of time to be fully realized. The so-called secondary reinforcement is H. RB335 reinforcing bar is inferior to the three-grade reinforcing bar in chemical composition and performance. But it is cheaper than the third grade steel bar in price.

　　與二級鋼筋相比較，三級鋼筋還是具有比較強的高度、韌性、焊接性能以及抗震性能的優點，此外用三級鋼筋替代二級鋼筋也是可以降低鋼材的消耗，節約鐵礦石、焦炭、電力的使用量，減少二氧化碳、廢氣、粉塵的排放量。所以，從這方面的利好因素來看，二級鋼筋停產也是勢在必行的事情。

　　Compared with the second-grade steel bar, the third-grade steel bar still has the advantages of relatively strong height, toughness, weldability and seismic performance. In addition, replacing the second-grade steel bar with the third-grade steel bar can also reduce the consumption of steel, save the use of iron ore, coke, electricity and reduce the emission of carbon dioxide, waste gas and dust. Therefore, from the perspective of the favorable factors in this respect, it is imperative to stop production of secondary reinforcement.

　　從近幾年的走勢行情分析來看，我國的高強度鋼筋產量和應用在逐年的提高，但是進展也不算快，從市場分析的結果來看，我國建筑用鋼筋有百分之六十采用的二級螺紋鋼，三級螺紋鋼筋和其以上的鋼筋也只占百分之三十左右。過國外高強鋼筋使用還是比較普遍的，用量一般在70%-80%，其中以400兆帕左右的鋼筋為主的。

　　According to the trend analysis in recent years, the output and application of high-strength steel bars in our country are increasing year by year, but the progress is not fast. According to the results of market analysis, 60% of the construction steel bars in our country are secondary screw steel, and only about 30% are tertiary screw steel bars and above. Overseas use of high-strength steel bars is relatively common, the amount is generally 70% - 80%, of which 400 MPa of steel bars are the main.

　　整體上分析來看，二級鋼筋停產終結果還是還是需要有一個適應的過程，靠單一的禁止市場銷售來控制，顯然也并不現實，關鍵點還是要從各大鋼廠研究入手，只有鋼廠不再生產二級鋼筋，那即便是工程師設計圖紙中出現二級鋼筋也并無從入貨。這才能大程度上斷掉市場的需求。

　　On the whole, the final result of the discontinuation of secondary reinforcement still needs an adaptive process. It is obviously unrealistic to control it by a single prohibition of market sales. The key point is to start with the research of major steel plants. Only steel plants do not produce secondary reinforcement anymore. Even if secondary reinforcement appears in engineer's design drawings, it will not be available for purchase. Only in this way can market demand be cut off to the greatest extent.
