In recent years, the performance of the construction steel market in China is weak as a whole, and the performance of hot-rolled threaded steel bars has been depressed for a long time. However, the steel industry itself is constantly trying and making efforts from various perspectives. It is believed that the market performance of hot-rolled rebar will be good in the near future.

　　目前的建筑鋼筋產品冷軋與熱軋是都有的，按照量級劃分，螺紋鋼筋是歸屬于小型型鋼鋼材的。因此其使用的范圍與靈活性就更多了。通常情況下是在鋼筋混凝土建筑構件的骨架。螺紋鋼通常用于鋼筋混凝土中，其中的螺紋起到了科學有效的增大摩擦力效果，使得鋼筋與混凝土的結合十分緊密，形成了咬合在一起的效果。使得在受外力的作用下是輕易不會產生抽動現象的，進而大幅度提高混凝土的強度。

　　At present, both cold-rolled and hot-rolled building steel products are available. Threaded steel bars are classified as small section steel according to their magnitude. Therefore, the scope and flexibility of its use are more. Usually, it is the skeleton of reinforced concrete building components. Threaded steel is usually used in reinforced concrete. Threads play a scientific and effective role in increasing friction, making the bond between steel and concrete very close, forming the effect of occlusion together. It makes it easy to avoid the phenomenon of pumping under the action of external force, and then greatly improves the strength of concrete.

　　熱軋螺紋鋼筋與普通的光圓鋼筋的區別是表面帶有縱肋和橫肋，他的螺紋排列通常是通常帶有二道縱肋和沿長度方向均勻分布的橫肋。這是比較常見的方式，但是有一些不同的比較少見的排列方式的在這里就不詳細說明了。

　　The difference between hot-rolled threaded bars and ordinary round bars is that the surface has longitudinal ribs and transverse ribs. The threads are usually arranged with two longitudinal ribs and uniformly distributed transverse ribs along the length direction. This is a more common way, but there are some different and less common ways of arranging, which are not explained in detail here.

　　目前市場上使用較多的是三級抗震鋼筋和四級抗震鋼筋，同樣規格方面的差距還是蠻大的，規格種類主要是12毫米14毫米16毫米18毫米20毫米22毫米25毫米28毫米32毫米的應用多。

　　At present, the market is mostly used three-level and four-level seismic reinforcement, the same specifications price gap is still large, specifications are mainly 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 25 mm, 28 mm, 32 mm, the most widely used.
