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
