欧标H型钢是一种截面面积分配更加优化、强重比更加合理的经济断面高效型材，因其断面与英文字母"H"相同而得名。由于H型钢的各个部位均以直角排布，因此H型钢在各个方向上都具有抗弯能力强、施工简单、节约成本和结构重量轻等优点，已被广泛应用。
欧标型钢为欧标系列H型钢，应用于各种钢结构建筑领域，海洋工程领域，能源领域。可供欧标角钢，欧标槽钢，欧标H型钢，也应用于海洋石油平台整体结构建造领域，LNG,炼油厂等模块钢结构。

4 分类和标记
4.1 分类
4.1.1 主要等级类别
此标准中所例举出的钢材的分类按照EN 10020中非合金优质钢的方法进行分类。
4.1.2组别和等级
此标准说明了八种钢材组别S 185，S 235，S 275，S 355，S 450，E 295，E 335和E 360。 其在机械性能上有所不同。钢材组别为S 235和S 275的等级型号是JR、J0和J2。钢材组别为S355的等级型号是JR、J0、J2和K2。钢材组别为S 450的等级型号是J0。不同的等级在其所要求的冲击功上不同。
4.2标记
4.2.1 标记应该按照EN 10025－1的要求规定。
注 曾用标记和EN 10025：1990和EN 10025：1990＋A1：1993中的曾用标记列表见附录A，表A.1。
4.2.2 标记应该包括：
－标准号（EN 10025－2）；
－钢材名称或者钢材牌号；钢材名称应包括：
－标记S（结构钢）或者E（工艺钢）；
－厚度≤16mm的最低屈服强度的标识，用Mpa表示1）；
－如果适用，关于冲击功数值的等级标记；
－如果适用，表示特殊操作的附加标记C（见表10、11、12和13）。
－标明“＋N或者＋AR” 当产品要求在＋N或＋AR条件下（见3.1、3.2和6.3）订货和供货时，其钢材牌号中应包括这样的标识“＋N或＋AR”。
示例 一种适于冷弯边（C）的结构钢（S）,其在室温条件下的最低屈服强度为355Mpa1），在0℃（J0）条件下的最低冲击功数值为27J，供货状态为正火轧制（或者轧制状态）钢材EN 10025－2－S355J0C＋N（或者＋AR）或者钢材EN 10025－2－1.0554+N (或者＋AR)
