Many friends who have just stepped into the steel market will say, is the disc steel bar a first-class steel? No matter how smart a person, even Mr. Shen, is, for the first time, he certainly does not know whether it is a first-class steel. Indeed, as a small white iron and steel industry, Xiaobian will have such doubts when he first entered the industry. Today, on this issue, I would like to introduce it to you.

　　盘圆钢筋，又称盘条，是建筑工程施工中常用的名称，表示直径是10毫米以下的钢筋，因为10毫米以下的钢筋容易弯曲，在运输前为减小长度，就在厂家把很长的钢筋卷成一圈一圈的圆环状，在建筑工地上把这样的钢筋简称为盘圆。而对于大家所疑惑的，是不是一级钢，小编告诉大家，它就是一级钢。

　　Disk bar, also known as wire rod, is a commonly used name in construction. It means steel bar with diameter less than 10 mm. Because steel bar with diameter less than 10 mm is easy to bend, in order to reduce the length before transportation, the manufacturers roll long steel bar into a circle and circle. In construction site, such steel bar is abbreviated as disk circle. And to everyone's doubts, is it a first-class steel, Xiaobian tells you, it is a first-class steel.

　　6-10mm的盘圆直径允许偏差正负0.40，不圆度允许偏差小于等于0.50，表面不得有裂纹，折叠等，允许有压痕及局部凸块、凹块、划痕、麻面等，但其尝试（实际尺寸）不大于0.2mm。盘圆表面为氧化铁皮，亦称脱碳层，颜色为深青色，肉眼观察，颜色越重质地越好。

　　The allowable deviation of disc diameter of 6-10mm is positive or negative 0.40, the allowable deviation of non-roundness is less than or equal to 0.50, the surface must not have cracks, folds, etc. The indentation and local bumps, concave blocks, scratches, hemp surfaces are allowed, but the attempt (actual size) is not more than 0.2mm. The surface of the disc is iron oxide, also known as decarbonization layer. The color is dark blue. The heavier the color, the better the texture.

　　因为市场上常见的盘圆钢筋生产厂家是首唐宣承，所以就主要介绍一下他们这几家的种类。

　　Because the common producer of disc reinforcement in the market is Xuancheng in the first Tang Dynasty, so I will mainly introduce their types.

　　首钢：分普线、高线和一线、二线、三线普线重量(盘重)均不稳。高线、一线1.75吨左右，二线1.3吨左右，三线1.45吨左右。

　　Shougang: The weights (disc weights) of branch, high and first, second and third lines are unstable. About 1.75 tons for high-speed lines and first-line lines, 1.3 tons for second-line lines and 1.45 tons for third-line lines.

　　宣钢：高线，盘重，1.54吨左右

　　Xuan Gang: High-speed wire, plate weight, about 1.54 tons唐钢：普线，盘重，1.90吨左右

　　Tangshan Iron and Steel Co., Ltd.: Ordinary line, plate weight, about 1.90 tons承钢：高线，盘重，1.60吨左右

　　Chenggang: High-speed wire, plate weight, about 1.60 tons所有线材均按检斤(实际过磅数)交货。

　　All wire rods are delivered according to the inspection kilograms (actual weights).
