圆钢与螺纹钢区别其实是显然易见的。光从表面上来看就可以区分。今天我们就来具体讲解一下这两类钢材之间的区别，也方便行业内人士在今后的工作中更好的了解这两种钢材。接下来济钢一级代理商厂家的小编为大家简单介绍一下吧。
It is easy to see the difference between round bar and screw steel. Light can be distinguished from the surface. Today we will explain the difference between these two types of steel, and also make it easier for the people in the industry to better understand these two kinds of steel in the future work. Next, Jinan Iron and steel level agents, manufacturers Xiaobian, for everyone to brief it.

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来表示。如“50”即表示为50毫米的圆钢。圆钢分为热轧、锻制和冷拉三种。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的供应，一般会用做钢筋、螺栓以及各种机械零件。大于25毫米的圆钢，主要是用于制造机械零件或者用做无缝钢管坯等。
Round steel: refers to the cross section of round solid steel, the specifications of the diameter of millimeters. Such as "50", that is 50 millimeters of round steel. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm of small round bars are mostly supplied by straight strips. They are generally used as reinforcing bars, bolts and various mechanical parts. Round steel larger than 25 mm, mainly used in the manufacture of mechanical parts or seamless steel tubes.
螺纹钢：建筑工地上是最常见的就是螺纹钢了，螺纹钢是带肋的直条钢筋。通常带有二道纵肋和沿长度方向均匀分布的横肋。螺纹钢属于小型型钢钢材，主要的用于钢筋混凝土建筑构件的骨架。在使用中要求有一定的机械强度、弯曲变形性能及工艺焊接性能。生产螺纹钢的原料钢坯为经镇静熔炼处理的碳素结构钢或者低合金结构钢，成品钢筋为热轧成形、正货或者热轧状态交货。
Rebar: the most common on the construction site is the rebar, which is a ribbed bar of steel. A horizontal rib with two longitudinal ribs and uniformly distributed along the length. The thread steel belongs to the small section steel, mainly used for the skeleton of the reinforced concrete construction member. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which has been treated by means of calm melting, and the finished product bars are delivered by hot rolling, normal or hot rolling.
