Cold-formed steel - varieties and technology
Wide variety of cold-formed steel, from the sub-section shape, with open, semi closed and closed, the main products are cold-formed channel steel, angle steel, Z section steel, cold-formed corrugated steel, square tube, rectangular tube, welded tube shaped, shutter doors and so on. Usually produced by cold-formed steel, the thickness of 6mm below the width of 500mm or less. Common specifications such as the Chinese side angle (limb length of 25 ~ 75 mm), the curling angle (limb length of 40 ~ 75 mm), channel (25 ~ 250 mm high), the curling channel (high of 60

Cold-formed steel
~ 250 mm), curling Z-shaped steel (High 100 ~ 180 mm) so on more than 400 specifications and varieties. Our products are widely used in mining, construction, agricultural machinery, transportation, bridges, petrochemical, light industry, electronics and other industries.
 Production of cold-formed steel is the main material of light steel structure, the use made of steel or steel roll forming. It can be produced not only a very thin wall thickness, but also greatly simplifies the production process, improve production efficiency. With the general method can produce hot-rolled production of uniform thickness is difficult, but a variety of complex cross section shapes and different profiles of cold-formed steel material. Except for a variety of cold-formed steel structures, but also widely used in vehicle manufacturing, agricultural machinery and so on. Many varieties of cold-formed steel, according to sub-section open, semi-closed, closed. By the shape of cold-formed Slip ring channel, angle steel, Z section steel, square tube, rectangular tube, Special Pipes, shutter doors. According to GB6725-92 provides cold-formed steel structure of the ordinary carbon negative, high-quality carbon structural steel, low alloy steel plates or steel cold-formed steel. Cold-formed steel is an economic cross-section of steel, but also energy efficient materials, is a new type of steel with a variety of great vitality, it is widely used in various areas of the country out of economic, its use can be divided into road divider plate around, steel, automobiles, container, steel formwork and scaffolding, railway vehicles, ships and bridges, steel sheet pile, transmission tower, etc. 10 other categories.Roll forming machine
Bending moment in the hollow square steel production, there are two different production forming process. One is the first round and then changed into a square or rectangular; the other is the direct prescription or rectangular. At present, the field of rectangular steel tube forming, direct prescription, into a moment the most advanced technology molding technology. Prescription or rectangular direct process than the first round and then changed into a square or rectangle of the process to be advanced. The first Roll forming  round and then changed into a square or rectangular process on the strip or coil material damage to the large; and direct prescription, into a moment of the process, the basic process in the molding material will not cause damage, to maintain the good mechanical properties Roll former  of raw materials and physical properties, ensuring product quality. It is understood that Taian Steel Plant is a large direct prescription, into a moment of technology is very good shape. In recent years, market demand for cold-formed steel in China is increasing, expanding the scope of application, the market prospect is very broad. Urgently needed development of stainless steel, galvanized sheet, high strength and ultra high strength low-alloy cold-formed steel material and the thick, complex and difficult series of ultra-thin cross-section cold-formed steel products.
