型鋼是一種有一定截面形狀和尺寸的條型鋼材,是鋼材四大品種(板、管、型、絲 )之一。根據斷面形狀,型鋼分簡單斷面型鋼和復雜斷面型鋼(異型鋼)。前者指方鋼、圓鋼、扁鋼、角鋼、六角鋼等;后者指工字鋼、槽鋼、鋼軌、窗框鋼、彎曲型鋼等。
型鋼的分類
按照鋼的冶煉質量不同,型鋼分為普通型鋼和優質型鋼。普通型鋼按現行金屬產品目錄又分為大型型鋼、中型型鋼、小型型鋼。普通型鋼按其斷面形狀又可分為工字鋼、槽鋼、角鋼、圓鋼等。
大型型鋼:大型型鋼中工字鋼、槽鋼、角鋼、扁鋼都是熱軋的,圓鋼、方鋼、六角鋼除熱軋外,還有鍛制、冷拉等。
工字鋼、槽鋼、角鋼廣泛應用于工業建筑和金屬結構,如廠房、橋梁、船舶、農機車輛制造、輸電鐵塔,運輸機械,往往配合使用。扁鋼在建筑工地中用作橋梁、房架、柵欄、輸電船舶、車輛等。圓鋼、方鋼用作各種機械零件、農機配件、工具等。
中型型鋼:中型型鋼中工、槽、角、圓、扁鋼,用途與大型型鋼相似。
小型型鋼:小型型鋼中角、圓、方、扁鋼,加工和用途與大型型鋼相似,小直徑圓鋼常用作建筑鋼筋

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
