Welded Steel Or Iron H Beam
Welded steel or iron H beam or metal beam is the main components for the prefabricated steel buildings, we have several production line for welded steel structure. W elded steel or iron H beam Advantages of us 1. Top qualification authorized by nation "Class-A qualification for steel...
Welded h-beam, for welding craft section H form, divided into submerged arc welding h-beam, high-frequency welding h-beam. Automatic submerged arc welding h-beam USES process: steel plate, slitting machine, set set, automatic submerged arc welding, testing - flange correction - web correction - end processing, sandblasting derusting, paint. Automatic submerged arc welding production line from next makings, assembling, welding all controlled by microcomputer, ensure the accuracy of the production size of h-beam, weld quality achieves the national standard.
Range of application:
H section steel is mainly used in industry and civil structure of beam and column.
Pieces of the industrial structure steel structure bearing bracket
Pieces of the underground engineering steel pile and retaining structure
Industrial equipment such as mixer petrochemical industry and power structure
Pieces of long span steel bridge components
In pieces, mechanical manufacturing frame structure of the ship
In pieces the train, automobile, tractor beam bracket
Conveyor belt, high-speed baffle support pieces ports
H section steel is a kind of economic cross section steel, widely used in industry, buildings, Bridges, oil drilling platform, etc., according to the forecast demand of h-beam in China about 2.5 million tons in 2005, demand for 5 million tons in 2010, but at present our country h-beam annual production capacity of 1.2 million tons, the market demand is very large.
1.High structural strength
Compared with i-steel, section modulus, load bearing conditions being the same, can save metal 10-15%.
2. The flexible design style, rich
In the same high beam, the steel structure of 50% than large width of concrete structure, so that the building is decorated more flexible.
3. Light weight structure
Compared with concrete structure dead weight is light, reduce weight, reduce the internal structure design, can make the building structure based processing demand is low, construction is simple, the cost is reduced.
4. High structure stability
Is given priority to with hot-rolled h-beam steel structure, its scientific and reasonable structure, good plasticity and toughness, high structure stability, applicable to withstand vibration and impact load of building structure, strong ability to resist natural disasters, especially suitable for some more earthquake belt structure. According to statistics, in the above magnitude 7's devastating earthquake disasters in the world, predominantly h-beam steel structure building victims is minimized.
5. Increase effective use area of structure
Compared with concrete structure, steel structure column cross-section area is small, which can increase the building effective use area, depending on architectural form, can increase effective use area of 4-6%.
6. Province work material
Compared with the welded h-beam, can significantly save work material, reduce the consumption of raw materials, energy and artificial, low residual stress, surface appearance and good quality.
7. To facilitate mechanical processing
Easy to structure connection and installation, but also easy to dismantle and used again.
8. The environmental protection
Using h-beam can effectively protect the environment, embodied in three aspects: one is compared with concrete, can use dry construction, small noise, less dust;2 it is due to reduce weight, foundation construction soil quantity is little, little damage to land resources, in addition a large number of concrete consumption, decrease rises increasely stone, be conducive to the protection of the ecological environment; Upon expiration of three is the service life of the building structure, the structure is disassembled, small solid garbage, high scrap recycling value.
9. High degree of industrial production
Is given priority to with hot-rolled h-beam steel structure industrial production degree is high, easy to machine manufacturing, intensive production, high precision, easy to install, easy to ensure quality, can make the factory built a real house, bridge fabrication plant, industrial workshop production plant, etc. Development of steel structure, create and driving the development of the hundreds of new industries.
10. The construction speed
Cover an area of an area small, and is suitable for all-weather construction, influenced by the climate conditions. Made of hot-rolled h-beam steel structure construction speed of about two to three times the speed of the concrete structure construction, capital turnover doubled, reduce financial expenses, saving investment.
