Brief introduction of packaging steel belt production material steel belt
　　 Steel strip, also called strip steel, is mostly supplied in coils, and its width is generally not more than 300 mm, and the width of rolled welded pipe billets is 700 mm. Compared with steel plates, steel strips have the advantages of high dimensional accuracy, good surface quality and ease of use. It is widely used as a blank for the production of welded steel pipes, cold-formed steel and thin steel plates. It is also commonly used in the manufacture of bicycle frames, rims, clamps, washers, spring blades, saw blades, blades, etc.
　　 Steel strip is divided into ordinary and high-quality steel according to the quality of steel, and divided into hot-rolled and cold-rolled according to the rolling method. The thickness of the hot-rolled ordinary steel strip is 2-6 mm, the thickness of the hot-rolled high-quality steel strip is 7 mm, and the thickness of the cold-rolled steel strip is 0.05-3.60 mm. The thickness of the tin-plated steel strip is the same as that of the tin-plated steel sheet. Cold-rolled steel strips are generally classified according to dimensional accuracy, surface state, edge state, material state, mechanical properties, surface quality, use, etc., and are represented by different symbols. The meaning of these classifications and various symbols should be understood during work. Prevent confusion.
