Features Of Steel Billets Steel billets result from the second stage of the steel production process. They are hot-rolled or forged from an ingot or strand cast. Smaller and longer than a bloom, billets are usually a square cross-section less than 36 square inches. They are used for the manufacture of all ‘long’ steel products such as bars, rods, pipes, tubes, wire and wire products.
Steel products refer to solid straight steel products with a certain section shape and size, including wire, profile and plate, which are formed by plastic processing except pipes. It can be divided into hot rolling, cold bending, cold rolling, cold drawing, extrusion, forging, hot bending, welding and special rolling according to the production method. It can be divided into railway, shipbuilding, mining, structure and construction according to its use. According to the material can be divided into carbon steel, alloy steel and stainless steel. At the same time, these steel products can be reprocessed to form semi-finished products or finished products to meet special requirements. We can according to the customer's different needs, according to the drawings or samples for reprocessing production.

Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
