型钢是一种有一定截面形状和尺寸的条型钢材,是钢材四大品种(板、管、型、丝 )之一。根据断面形状,型钢分简单断面型钢和复杂断面型钢(异型钢)。前者指方钢、圆钢、扁钢、角钢、六角钢等;后者指工字钢、槽钢、钢轨、窗框钢、弯曲型钢等。
型钢的分类
按照钢的冶炼质量不同,型钢分为普通型钢和优质型钢。普通型钢按现行金属产品目录又分为大型型钢、中型型钢、小型型钢。普通型钢按其断面形状又可分为工字钢、槽钢、角钢、圆钢等。
大型型钢:大型型钢中工字钢、槽钢、角钢、扁钢都是热轧的,圆钢、方钢、六角钢除热轧外,还有锻制、冷拉等。
工字钢、槽钢、角钢广泛应用于工业建筑和金属结构,如厂房、桥梁、船舶、农机车辆制造、输电铁塔,运输机械,往往配合使用。扁钢在建筑工地中用作桥梁、房架、栅栏、输电船舶、车辆等。圆钢、方钢用作各种机械零件、农机配件、工具等。
中型型钢:中型型钢中工、槽、角、圆、扁钢,用途与大型型钢相似。
小型型钢:小型型钢中角、圆、方、扁钢,加工和用途与大型型钢相似,小直径圆钢常用作建筑钢筋

Type steel is a kind of strip steel with a certain cross-section shape and size. It is one of the four major types of steel(board, pipe, type, and silk). According to the shape of the section, the type of steel is divided into simple section steel and complex section steel(type steel). The former refers to square steel, round steel, flat steel, corner steel, hexagonal steel, etc.; The latter refers to industrial steel, groove steel, steel rails, window frame steel, curved steel and so on.
Classification of steels
According to the smelting quality of steel, type steel is divided into ordinary steel and high-quality steel. Ordinary steel is divided into large steel, medium steel and small steel according to the current metal product catalogue. Ordinary steel can be divided into I-shaped steel, trough steel, angle steel, round steel and so on according to its cross-section shape.
Large steel: Large steel type steel, steel, steel, angle steel, flat steel are all hot rolling, round steel, Square steel, hexagonal steel in addition to hot rolling, forging, cold pull and so on.
Industrial steel, slot steel, and angle steel are widely used in industrial buildings and metal structures, such as factory buildings, bridges, ships, agricultural machinery and vehicles manufacturing, transmission towers, and transportation machinery. Flat steel is used as a bridge, housing frame, fence, transmission ship, vehicle, etc. in construction sites. Round steel and square steel are used as various mechanical parts, agricultural machinery accessories, tools, etc..
Medium steel: Medium steel workers, troughs, angles, circles, flat steel, similar in use to large steel.
Small steel: small steel medium angle, round, Square, flat steel, processing and use similar to large steel, small diameter round steel is often used as a building steel bar
