Large domestic welded pipe galvanized pipe manufacturers offer

I. Classification and classification of steel furnaces refining the molten steel is cast iron and steel material billets, ingots or billets after pressure processing into steel (steel products). Many different types of steel, and can be divided into two types, plate, tube and wire four major categories. 1, many varieties of steel type of steel, is a cross-sectional shape and size has a solid bar of steel. Its cross-sectional shape of the different cross-section is divided into two kinds of simple and complex. The former include round, square steel, flat steel, hexagonal and angles; the latter include rails, beams, channels, steel and shaped steel frames. The small diameter of 6.5-9.0mm round, said wire. 2, steel class is a generous surface area ratio and have a lot of flat steel. According to the thickness of the different sub-sheet (thickness 25mm) three. Steel strip included in the class. 3, pipe type is a hollow section steel bar. Sectional shape can be divided according to their different tube, square tube, hexagonal tubes and a variety of profiled steel. And can be divided according to different processing of seamless and welded steel pipe into two categories. 4, steel type wire is wire again cold products. According to the shape of the different sub-round wire, flat wire and steel wire triangle. In addition to the direct use of steel, but also for the production of steel wire rope, steel wire and other grain products.
