C-shaped steel and channel steel The difference
There are many types of VS-. shaped steel, divided into transverse shapes, including open, semi-closed and closed. The main products include cold-formed profile steel, angle steel, Z-shaped steel, cold-formed corrugated steel sheets, square tubes, rectangular tubes, welded steel tubess of special shapes, roller shutter doors, 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 25-250mm), internally rolled profile steel (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 its wall thickness pmay be very fine, 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 structures, 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 regulations, C-shaped steel is made of stainless steelr of ordinary carbon structural steel, high quality carbon structural steel, low alloy structural steel plate or steel strip, 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 areas of the national economy. 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 a-frame windowssteel, welded pipes. for the transportation of low-pressure fluids, general-purpose open C-shaped steel, structural C-shaped steel for steel structures, as well as cold-formed profiles of various cross sections, have been used in construction, machinery, nuclear power and automobiles. , railways, agricultural machinery, chemicals, petroleum, refrigeration, food, textiles, medical care, supermarkets, containers and other industrial and civil industries. It is widely used in China, especially in emerging industries. The demand for C-shaped steel shows strong demand. “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.e of C with cutting-edge development; directions and complex fractureThe potential market for surface, ultra-thick, ultra-thin and C-shaped series steel is quite large, and the development prospects are broad. 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, the annual consumption 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.
Which profile is the most cost-effective for photovoltaic supports, taking into account various factors such as price, convenience of construction, load, etc.
1. Different definitions
< p>C-shaped steel: C-shaped steel is automatically processed and formed by steel forming machine en C shape. The C shape steel forming machine can automatically complete the C shape steel forming process according to the given C shape 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 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 pMainly 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, beveled-edged C-shaped steel, internally rolled C-shaped steel, internally beveled C-shaped steel, roof (wall) purlin C-shaped steel, automobile profile C-shaped steel, C-shaped steel highway column, C-shaped steel solar support (21-80 series), steel formwork support C-shaped steel, C-shaped steelPrecision C 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 divided into 4 types according to their shape: cold-formed equal edge profile steel, cold-formed uneven edge profile steel, cold-formed inner curved profile steel and exterior formed steel Cold. curved profiled steel.
According to the theory of steel structure, the channel steel wing plate must supportstrength, meaning the channel steel must be upright instead of lying down.
