一种是根据几何学的几何形状对横截面的形状和肋骨之间的距离进行分类或分类。例如,在英国标准(bs4449),螺纹钢分为I型和II型。这种分类主要反映螺纹钢的抓持性能。二是基于性能的分类(级),例如我国现行执行标准,螺纹钢(GB1499.2-2007)线1499.1-2008),根据强度等级的螺纹钢分为3个等级(屈服点、抗拉强度);日本工业标准(jisg3112)将螺钉钢分为5种类型,根据综合性能;英国标准(钢筋性能测试成绩也在bs4461指定。此外,还可按其用途分类钢筋,如钢筋混凝土和普通钢筋,以及预应力混凝土用热处理钢筋。

螺纹钢的进出口情况:螺纹钢是中、以上建筑构件,必须使用钢材。我国每年都有进口量。主要生产国和地区是日本和西欧。近年来出口螺纹钢的数量增加了。国内主要出口厂商是北京、天津、上海、武汉、四川、辽宁等省市的钢铁企业。主要地区有香港、澳门和南洋。进口螺纹钢横向肋形主要为规则方螺纹或普通方螺纹。横肋几何是国内主要的钢螺旋、人字、月牙三。螺纹钢的订购原则一般以机械性能和机械强度指标为依据,满足工程设计要求。

One is to classify or classify the shape of the cross section and the distance between the ribs according to the geometry of the geometry。 For example, in the British Standard (BS4449), the screw steel is divided into type I and type II。 This classification mainly reflects the grip performance of threaded steel。 The two is based on the performance classification (grade), such as the current implementation standards of our country, the screw steel is (GB1499。2-2007) wire 1499。1-2008), the screw steel is divided into 3 grades according to the strength grade (yield point / tensile strength); the Japanese industrial standard (JISG3112) divides the screw steel into 5 types according to the comprehensive performance; the British Standard ( Some grades of performance test for rebar are also specified in BS4461。 In addition, it can also classify the rebar according to its purpose, for example, it is divided into reinforced concrete and ordinary reinforcement, and heat treated steel bar for prestressed concrete。


The import and export situation of rebar steel: screw steel is medium and above building components, and steel must be used. Our country has import volume every year. The main producing countries and regions are Japan and Western Europe. The number of export threaded steel has increased in recent years. The main domestic export manufacturers are iron and steel enterprises in Beijing, Tianjin, Shanghai, Wuhan, Sichuan, Liaoning and other provinces and cities. The main areas are Hong Kong, Macao and Southeast Asia. The transverse rib geometry of imported thread steel is mainly regular square or ordinary square thread. The transverse rib geometry are the main domestic steel helical, herringbone, crescent three. The ordering principle of thread steel is generally based on mechanical performance and mechanical strength index, which meets the requirements of engineering design.
