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.

　　盤圓鋼筋，又稱盤條，是建筑工程施工中常用的名稱，表示直徑是10毫米以下的鋼筋，因為10毫米以下的鋼筋容易彎曲，在運輸前為減小長度，就在廠家把很長的鋼筋卷成一圈一圈的圓環狀，在建筑工地上把這樣的鋼筋簡稱為盤圓。而對于大家所疑惑的，是不是一級鋼，小編告訴大家，它就是一級鋼。

　　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的盤圓直徑允許偏差正負0.40，不圓度允許偏差小于等于0.50，表面不得有裂紋，折疊等，允許有壓痕及局部凸塊、凹塊、劃痕、麻面等，但其嘗試（實際尺寸）不大于0.2mm。盤圓表面為氧化鐵皮，亦稱脫碳層，顏色為深青色，肉眼觀察，顏色越重質地越好。

　　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.

　　因為市場上常見的盤圓鋼筋生產廠家是首唐宣承，所以就主要介紹一下他們這幾家的種類。

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

　　首鋼：分普線、高線和一線、二線、三線普線重量(盤重)均不穩。高線、一線1.75噸左右，二線1.3噸左右，三線1.45噸左右。

　　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.

　　宣鋼：高線，盤重，1.54噸左右

　　Xuan Gang: High-speed wire, plate weight, about 1.54 tons唐鋼：普線，盤重，1.90噸左右

　　Tangshan Iron and Steel Co., Ltd.: Ordinary line, plate weight, about 1.90 tons承鋼：高線，盤重，1.60噸左右

　　Chenggang: High-speed wire, plate weight, about 1.60 tons所有線材均按檢斤(實際過磅數)交貨。

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