25、肋钢筋的英文缩写后加“细”的英文（Fine）首位字母。如：HRBF335、HRBF400、HRBF500。有较高要求的抗震结构适用牌号为：在已有牌号后加E（例如：HRB400E、HRBF400E）。1主要用途：广泛用于房屋、桥梁、道路等土建工程建设。主要产地：螺纹钢的生产厂家在我国主要分布在华北和东北，华北地区如首钢、唐钢、宣钢、承钢、山西中阳钢厂、保定普瑞钢铁等，东北地区如西林、北台、抚钢等，这两个地区约占螺纹钢总产量50%以上。螺纹钢与光圆钢筋的区别是表面带有纵肋和横肋，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，主要用于钢筋混凝土建筑构件的骨架。在使用中要求有一定

26、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低合金结构钢，成品钢筋为热轧成形、正火或热轧状态交货。种类螺纹钢常用的分类方法有两种：一是以几何形状分类，根据横肋的截面形状及肋的间距不同进行分类或分型，如英国标准（）中，将螺纹钢分为型、型。这种分类方式主要反应螺纹钢的握紧性能。二是以性能分类（级），例如我国现行执行标准，螺纹钢为（.2-2007）线材为1499.1-2008）中，按强度级别（屈服点/抗拉强度）将螺纹钢分为个等级；日本工业标准（）中，按综合性能将螺纹钢分为个种类；英国标准（）中，也规定了螺纹钢性能试验的若干等级。此外还可按用途对螺纹钢进行

27、分类，如分为钢筋混凝土用普通钢筋及予应力钢筋混凝土用热处理钢筋等。进出口情况螺纹钢是中型以上建筑构件必须用钢材，我国每年都有一定进口批量。主要生产国和地区为日本、西欧。出口螺纹钢的数量近年有所增长，国内主要出口生产厂家为北京、天津、上海、武汉、四川、辽宁等省市的钢铁企业。输往地区主要为港澳及东南亚地区。进口螺纹钢的横肋几何形状主要为普通方形螺纹或普通斜方形螺纹。国产螺纹钢的横肋几何形状主要有螺旋形、人字形、月牙形三种。螺纹钢的定货原则一般是在满足工程设计所需握紧性能要求的基础上，以机械工艺性能或机械强度指标为主。规格及外观质量（）规格：螺纹钢的规格要求应在进出口贸易合同中列明。一般应包括标准的

28、牌号（种类代号）、钢筋的公称直径、公称重量（质量）、规定长度及上述指标的允差值等各项。我国标准推荐公称直径为6、8、10、12、16、20、25、32、40、50的螺纹钢系列。1供货长度分定尺和倍尺二种。我国出口螺纹钢定尺选择范围为，日本产螺纹钢定尺选择范围为.；国产内销螺纹钢若合同中无注明要求时，通常定尺为9m、12m两个长度。（）外观质量：表面质量。有关标准中对螺纹钢的表面质量作了规定，要求端头应切得平直，表面不得有裂缝、结疤和折迭，不得存在使用上有害的缺陷等。外形尺寸偏差允许值。螺纹钢的弯曲度及钢筋几何形状的要求在有关标准中作了规定。如我国标准规定，直条钢筋的弯曲度应不影响正常使用，总弯
