钢材是国家建设和实现四化必不可少的重要物资，应用广泛、品种繁多，根据断面形状的不同、一般分为型材、板材、管材和金属制品四大类、为了便于组织钢材的生产、订货供应和搞好经营管理工作。

Steel is an important material for national construction and the realization of the four modernization indispensable, wide application, wide variety, according to the different section shape, generally divided into sections and plates, pipes and metal products of four categories, in order to facilitate the organization of steel production, supply and management order management.

炼钢炉炼出的钢水被铸成钢坯，钢锭 或钢坯经压力加工成钢材。 钢材按外形可分为型材、板材、管材、金属制品四大类。

The steel produced by the steelmaking furnace is cast into billet, and the ingot or billet are processed into steel by pressure. According to the shape of steel, it can be divided into four categories: profiles, plates, pipes and metal products.

1、型钢类：型钢品种很多，是一种具有一定截面形状和尺寸的实心长条钢材。按其断面形状不同又分简单和复杂断面两种。前者包括圆钢、方钢、扁钢、六角钢和角钢；后者包括钢轨、工字钢、槽钢、窗框钢和异型钢等。直径在 6.6 -9.0mm 的小圆钢称线材。

1. Type steel: a variety of steel type steel, is a solid steel with a certain section shape and size. According to the different shape of the section, it is divided into two kinds of simple and complex sections. The former includes round steel, Fang Gang, flat steel, six angle steel and angle steel, and the latter includes rail, I-steel, channel steel, window frame steel and special-shaped steel. A small round steel with a diameter of 6.6 -9.0mm is called a wire.

2 、钢板类：是一种宽厚比和表面积都很大的扁平钢材。按厚度不同分薄板（厚度 < 4mm ）、中板（厚度 4 -25mm ）和厚板（厚度 > 25mm ）三种。钢卷包括在钢板类内。

2, steel plate: it is a flat steel with wide thickness ratio and large surface area. Three kinds of thin plates (thickness < 4mm), medium plate (thickness 4 -25mm) and thick plate (thickness > 25mm) are divided according to the thickness. The steel coil is included in the steel plate.

3 、钢管类：钢管类是一种中空截面的长条钢材。按其截面形状不同可分圆管、方形管、六角形管和各种异形截面钢管。按加工工艺不同又可分无缝钢管和焊管钢管两大类。

3, steel pipe class: steel pipe is a kind of hollow section of the long steel. According to the shape of the section, it can be divided into circular tube, square tube, hexagonal tube and various steel tube with different cross section. According to the processing technology, it can be divided into two kinds of seamless steel pipe and pipe welded pipe.

4 、钢丝类：钢丝是线材的再一次冷加工产品。按形状不同分圆钢丝、扁形钢丝和三角形钢丝等。钢丝除直接使用外，还用于生产钢丝绳、钢纹线和其他制品。

4, steel wire: steel wire is another cold processing product of wire. According to the different shape of round steel wire, flat wire and triangle wire etc.. In addition to the direct use of steel wire, it is also used for the production of steel wire rope, steel lines and other products.
