螺紋鋼直徑符號和螺紋鋼型號是消費者在購買螺紋鋼時必須要考慮的因素，這個是不能不知的，在很多建筑圖紙中，我們會發(fā)現(xiàn)Φ這個符號，有些朋友不知道這是什么意思。其實這是螺紋鋼直徑符號。螺紋鋼直徑符號是用來表示鋼筋直徑的大小，比如鋼筋直徑為20mm,那么就表示為Φ20。
Rebar diameter and thread steel types are symbol factors of consumers must purchase rebar to consider, this is not known, in many architectural drawings, we will find that with this symbol, some friends don't know what it means. In fact, this is the diameter symbol of thread steel. The diameter of the steel mark is used to indicate the diameter of the steel bar. For example, the diameter of the steel bar is 20mm, then it is expressed as "20".

螺紋鋼也是分型號的。螺紋鋼型號的劃分可以從多個角度，濟鋼一級代理一般主要根據(jù)其化學成分、制作工藝、外部形態(tài)、直徑大小以及用途來劃分。如果我們按直徑大小來劃分的話，就分為粗鋼筋、細鋼筋和鋼絲，它們的主要區(qū)別就是直徑大小不同。
Thread steel is also of different sizes. The type of threaded steel can be divided from many angles, the first class agent of Jinan Iron and Steel Co., Ltd., mainly based on its chemical composition, manufacturing process, external shape, diameter and use. If we are divided by diameter, they are divided into coarse steel bars, thin steel bars and steel wires. The main difference is that they are different in diameter.
紋鋼是表面帶肋的鋼筋，亦稱帶肋鋼筋，通常帶有2道縱肋和沿長度 方向均勻分布的橫肋。橫肋的外形為螺旋形、人字形、月牙形3種。濟鋼一級代理用公稱直徑的毫米數(shù)表示。帶肋鋼筋的公稱直徑相當于橫截面相等的光圓鋼筋的公稱直徑。帶肋鋼筋由于肋的作用，和混凝土有較大的粘結(jié)能力，因而能更好地 承受外力的作用。帶肋鋼筋廣泛用于各種建筑結(jié)構、特別是大型、重型、輕型薄壁和高層建筑結(jié)構。
Ribbed steel is a surface ribbed steel bar, also called ribbed steel bar, usually with 2 longitudinal ribs and transverse ribs uniformly distributed along the length. The transverse rib shape is helical, herringbone, crescent 3. The first grade agent of Jinan Iron and steel company is represented by the nominal diameter of millimeters. Nominal diameter of round steel bars of equal diameter equal to the cross section of ribbed bars. Because of the function of rib and the greater bonding ability of concrete, ribbed steel bar can bear the effect of external force better. Ribbed steel bars are widely used in a variety of building structures, especially large, heavy, light, thin-walled and high-rise structures.
