The difference between C-shaped steel and section steel
There are many types of C-shaped steel, divided into shapes of cross section, notably open and semi-closed. and closed. The main products are cold-formed groove steel, angle steel, Z-shaped steel, cold-formed corrugated steel plate, square tube, rectangular tube, steel tube special shape electrically welded, roller shutter door, etc. C-shaped steel is generally produced with a thickness of less than 6mm and a width of less than 500mm. Commonly used specifications in China include equal edge angle steel (member length 25-75mm), interior rolled angle steel (member length 40-75mm), profile steel ( height 25-250 mm), steel for profiles internally rolled (height 60-250mm)), Z-shaped curved steel (height 100~180mm) and more than 400 specifications and varieties. The products are widely used in mining, construction, agricultural machinery, transportation, bridge, petrochemical, light industry, electronics and other industries.
C-shaped steel is the main material for manufacturing lightweight steel structures. It is made of cold-formed steel plates or steel strips. Not only can its wall thickness be very thin, but it also greatly simplifies the production process and improves production efficiency. It can produce various C-shaped profiles and steels of different materials with uniform wall thickness but complex cross-section shapes that are difficult to produce by ordinary hot rolling methods. In addition to being used in various building structurestimes, C-shaped steel is also widely used in vehicle manufacturing, agricultural machinery manufacturing, etc. There are many types of C-shaped, split opening, semi-closed opening and closed opening steel depending on the section. According to the shape, there are cold-formed steel profiles, angle steel, Z-shaped steel, square tubes, rectangular tubes, special-shaped tubes, roller shutter doors, etc.
According to GB6725-92 regulation, C-shaped steel is composed of ordinary carbon structural steel, high-quality carbon structural steel, structural steel plate low alloy or strip steel, cold formed. C-shaped steel is an economical cross-section steel and high-efficiency energy-saving material. This is a new type of steel with high vitality. It is widely used in various fields of economics national. in highway guardrails, steel structures, automobiles and containers, steel formworks and scaffolding, railway vehicles, ships and bridges, steel sheet piles, transmission towers, etc. . 10 categories.
The main varieties of C-shaped steel currently available in China include: cold-formed square rectangular tubes for structures, cold-formed steel for passenger cars, steel profiles for roller shutter doors and steel windows, welded pipes. for transportation of low pressure fluids, general purpose open C-shaped steel, construction C-shaped steel for steel structures and cold-formed sections of various sections have been used in construction , machinery, nuclear power, automobiles, railways, agriculture machinery, chemicals, petroleum, refrigeration, foodation, textiles, medicines, etc. It is widely used in industrial and civil industries such as hospitals, supermarkets and containers. In particular, the demand for C-shaped steel in emerging industries shows a "large volume and wide coverage" trend. At present, China produces a small amount of C-shaped steel made of stainless steel, galvanized sheet, high-strength steel and low alloy steel and needs to be imported C-shaped steel products with cutting-edge development; Complex directions and cross sections, series ultra-thick, ultra-thin and C-shaped steel have a large potential market and broad development prospects. At present, there are very few such C-shaped steels in China, and many products are still virgin, and some can only be manufactured through imports. For example, annual consumptionThe amount of C-shaped galvanized steel used in luxury buses is at least 3,000 tons. At present, imported products are mainly used and demand continues to increase.
1. Different definitions
C-shaped steel: C-shaped steel is automatically formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the C-shaped steel forming process according to the given C-shaped steel size.
Roll steel: Roll steel is a long strip of steel with a groove-shaped cross section. It is a carbon structural steel used in construction and machinery. This is a profiled steel material with a complex cross section. section and a groove-shaped cross section.
2. Different Applications
C-shaped steel: C-shaped steel is widely usedt used in purlins and wall beams of steel structure buildings, and can also be assembled into lightweight roof trusses, supports and other construction elements. Additionally, it can also be used for columns, beams and arms in light mechanical manufacturing.
Profile steel: Profile steel is mainly used in building structures, curtain wall projects, mechanical equipment and vehicle manufacturing.
3. Different types
C-shaped steel: galvanized C-shaped steel, hot-dip galvanized C-shaped steel cable tray, C-shaped steel glass slot, glass curtain wall C-shaped steel, cable duct C-shaped steel, Reinforced C-shaped steel, Double arm C-shaped steel, Single-sided C-shaped steel, Manual forklift C-shaped steel, ?< /p>
Unequal straight-sided C-shaped steel, straight-sided C-shaped steel, e steeln Beveled Edge C Shape, Internally Rolled C Shape Steel, Internally Beveled C Shape Steel, Roof (Wall) Purlin C Shape Steel, Automotive Profile C Shape Steel, Steel Highway Column C-shaped, C-shaped steel solar bracket (21-80 series), C-shaped steel formwork bracket, precision C-shaped steel for equipment, etc.
Section steel: Section steel is divided into ordinary section steel and light section steel. The specifications of hot-rolled ordinary profile steel are 5-40#. The specifications of hot rolled flexible channel steel provided by agreement between the supplier and the buyer are 6.5 to 30#. Section steel is primarily used in building structures, vehicle manufacturing, other industrial structures and fixed panels are often used in conjunction with I-beams.
Steel sections can be direferred to in 4 types according to their shape: cold-formed equal-edged profile steel, cold-formed uneven-edged profile steel, cold-formed internal curved profile steel and cold-formed external steel . curved profiled steel.
According to the steel structure theory, the channel steel wing plate should bear the force, which means the channel steel should be upright instead of lying down.
