strut channels

Speed up the implementation process of building factory. China's future is bound to vigorously promote the construction industry "factory" production, assembly-type "construction" of the construction method, not only because it is common practice overseas, the key is in line with low-carbon, energy saving, environmental protection requirements, the general trend. Building construction beams, plates, columns, stairs, etc. all in the factory assembly line production, greatly reducing the labor intensity. Workers are also engaged in the construction industry, but in a fixed place to work on time, in the bright and clean canteen, a daily hot bath, dormitory conditions better than the poor conditions of migrant workers at home, so in this environment, workers soon to find the feeling of industrial workers. Prefabricated housing, according to the factory in such a survey, the average worker monthly salary 2000 yuan, 80 yuan per day, on the whole staff was reassuring.

Efforts to reduce the fragmentation of employment services. To the Ministry of Housing and Urban Construction of national qualification standards for new business as an opportunity to re-place, as far as possible to improve labor efficiency through technological innovation, with the factory, mechanization to reduce labor intensity, to reduce labor and employment purposes. For example:  made the three countries built their own three patents on the promotion and application of embedded scaffold planks, not only significantly improve the efficiency, increase the safety factor of scaffolding erection, and can use less number of significant Jia Zigong, China Railway System build a huge number of high-speed railway construction scaffold, has been tasted this easy, fast and secure scaffold boards of the sweetness.

Currently the construction industry is still labor-intensive industries, rely heavily on the labor force within a short time, fundamentally change the phenomenon, the proposed construction enterprises should further establish a "not to do everything, but to where the" concept of modern construction enterprises employing, devote great efforts to set up a business its own industrial workers. So to be a multi-pronged, Duocuobingju, from all levels of reserves to increase the absorption and training of human resources so that efforts to meet the country's vast needs of the construction of the situation.

Light steel channel, often referred to as colloquially vendors by product name (such as "Kinder", "Unistrut", "Super Strut", "support", "Met strut") variety, is a standardized cold-formed steel (or sometimes aluminum) structure system construction, light construction for the power industry's support is often used to support, such as air conditioning or ventilation system wiring, plumbing, or mechanical parts. Pillar formation and collapse inward into the strut channel steel to form a metal piece, curved lips, to provide additional stiffness and location, load interconnect components. Some of the basic pillars of the sort usually have holes to facilitate the networking infrastructure or security support structure.

Advantages in establishing steel channels of the main pillars, there used to quickly and easily connected together, and the support of other projects the strut channel steel length, using a special fasteners and bolts of the pillars of many varieties to choose from. It can be very quickly with a minimum of assembly tools, only slightly well-trained workforce, which in many applications, greatly reducing costs. Installation is often a pillar of the c channel steel can modify or add, if need be relatively easy. Support strut channel steel for most applications the only option is to customize the constituent stocks of steel and other commodities, the need for welding and / or large-scale drilling and connection, it has no advantages.

In the unit, a typical passage from 1 5 / 8 inch box 1 5 / 8 inch to form the basic support. In metric units, this is a 41 mm 41 mm units. A variety of sizes and shapes made of other combinations.

Provide a variety of steel channels from the supplier column, often used in electrical, plumbing found, supply warehouse and directory structure.

The lowest temperature at which plain carbon steel can begin to melt, its solidus, is 1130 °C. Steel never turns into a liquid below this temperature. Pure Iron ('Steel' with 0% Carbon) starts to melt at 1492 °C (2720 °F), and is completely liquid upon reaching 1539 °C (2802 °F). Steel with 2.1% Carbon by weight begins melting at 1130 °C (2066 °F), and is completely molten upon reaching 1315 °C (2400 °F).In order for a fireproofing product to qualify for a certification listing of strut channels steel, through a fire test, the critical temperature is set by the national standard, which governs the test. In Japan, this is below 400°C. In China, Europe and North America, it is set at ca. 540°C. The time it takes for the steel element that is being tested to reach the temperature set by the national standard determines the duration of the fire-resistance rating.

Structural steel requires external insulation (fireproofing) in order to prevent the steel from weakening in the event of a fire. When heated, steel expands and softens, eventually losing its structural integrity. Given enough energy, it can also melt. Heat transfer to the steel can be slowed by the use of fireproofing materials. While concrete structures that comprise buildings are able to achieve fire-resistance ratings without additional fireproofing, concrete can be subject to severe spalling, particularly if it has elevated moisture content. Fireproofing is available for concrete but this is typically not used in buildings. Instead, it is used in traffic tunnels and locations where a hydrocarbon fire is likely to break out. Thus, steel and concrete compete against one another not only on the basis of the price per unit of mass but also on the basis of the pricing for the fireproofing that must be added in order to satisfy the passive fire protection requirements that are mandated through building codes. Common fireproofing methods for strut channels steel include intumescing, endothermic and plaster coatings as well as drywall, calcium silicate cladding, and mineral or high temperature insulation wool in the form of blanket.

Strut channel is a standardized formed steel (or sometimes aluminum) structural system used in the construction and electrical industries for light structural support, often for supporting wiring, plumbing, or mechanical components such as air conditioning or ventilation systems.

The main advantage of strut channel in construction is that there are many options available for rapidly and easily connecting lengths together and other items to the strut channels , using various specialized strut-specific fasteners and bolts. It can be assembled very rapidly with minimal tools and only moderately trained labor, which reduces costs significantly in many applications.

TEX reported that a major integrated steel company of Japan is considering setting the target price level at USD 850 per tonne CNF in its H beam and sheet pile exports to Asian destinations, mainly to China, for June and July shipments, on which the company's export negotiations are expected to start shortly. The company has already negotiated part of its sheet pile exports to China at around USD 840 per tonne CNF for June shipments. As a result, it is likely that the company will seek a higher price level of USD 900 per tonne CNF in its sheet exports for July shipments.

In Asia, transaction prices of various steel products(such as steel sheet pile ,strut channel steel ) are shooting up after it has become clear that the prices of raw materials will advance considerably from April onward. Until recently, prices of steel products such as heavy plates stood at a low level. At present, though, even prices of heavy plates for shipbuilding border on USD 800 per tonne FOB in shipments out of Japan to South Korea. It was once considered difficult for a price increase to take effect in those Japano Korean heavy plate deals.

Under the existing circumstances, Japanese exports of sheet piles and H beams should fetch appropriate prices of at least USD 850 per tonne CNF, a price level that is commensurate with the going prices of other steel products(such as c channel steel ,u channel steel ), believe the Japanese parties concerned. As a result, no Japanese exports of sheet piles and H beams would be made for June shipments unless the price is agreed at USD 850 per tonne CNF or beyond.

Until now, a price settlement of USD 800 per tonne CNF has served as the norm of a Japanese integrated steelmaker's sheet pile exports to Asian destinations. In China, construction is under way for a spate of athletic facilities in southern coastal provinces in relation to the Asian Games to open in Guangzhou in November 2010.

Accordingly, local demand for sheet piles is surging, in which firm supplies of around 5,000 tonnes are already under contract for June shipments. Also, negotiated prices of sheet piles in wide sizes are said to have hit a slightly less than USD 850 per tonne CNF.

Meanwhile, an adequate price increase is slow to take hold when it comes to H beam exports by a Japanese integrated steelmaker to South Korea. Having an impact are local H beam stocks at a high level in the repercussions of H beam imports from China. Import arrivals from China totaled 80,000 tonnes in March 2010 and they are expected to total around 40,000 tonnes in April 2010. As far as South Korea's Hyundai Steel Co is concerned, the company has increased its domestic sales price of H beams by KRW 50,000 per tonne to KRW 910,000 per tonne. At the same time, the company is said to have abolished its volume discount of KRW 50,000 to KRW 100,000 per tonne. Still, local steel manufacturer haven't necessarily accepted the whole of Hyundai Steel's H beam price increase. As a result, continued transactions of H beams are reported at KRW 860,000 per tonne.

In this connection, the going prices of are approaching USD 800 per tonne CNF after they have topped USD 780 per tonne CNF both in Japanese and South Korean H beam exports to Asian destinations, market observers point out.
