The Classification Of Profile Steel

Some people say that profile steel is one of the four varieties of steel (plate, tube, type, wire); it is said that according to the cross-section shape, profile steel can be divided into simple section steel and complex section steel (shaped steel); also some people say that profile steel is generally used for machining, structural connections, then the steel product parameters, really as the world described it? What is the classification of it? 

Section steel use and classification: 

According to the different quality of steel smelting, steel is divided into ordinary steel and high-quality steel. Ordinary steel products according to the current catalog is divided into large-size steel, medium-sized steel, small steel. Ordinary section steel according to its shape can be divided into I-beam, channel, angle, round and so on. 

Large steel: large steel in the I-beam, channel, angle, flat steel are hot-rolled, round, square steel, hexagonal addition to hot-rolled, there are forging, cold drawing and so on. 

I-beam, channel steel, angle steel is widely used in industrial construction and metal structures, such as factories, bridges, ships, agricultural vehicle manufacturing, transmission tower, transportation machinery, often with the use. Flat steel in the construction site as a bridge, frame, fence, transmission ships, vehicles. Round steel, square steel for a variety of mechanical parts, agricultural machinery parts, tools and so on. Medium-sized steel: medium-sized steel in the work, slot, angle, round, flat steel and large steel use similar. Small steel: small steel in the angle, round, square, flat steel processing and use and large steel is similar to small diameter steel bar is often used as building.
