Hot-rolled H-beam according to different uses rational allocation of cross-sectional dimensions of high aspect ratio, with excellent mechanical properties and superior performance. ★ high structural strength. Compared with the beam, a large section modulus, in carrying conditions are the same, you can save 10-15% metal. ★ design flexibility and rich. Under the same conditions of high beams, steel structures bay bay than 50% larger concrete structure, so that the building layout more flexible. ★ light weight structure. Compared with the light weight concrete structures, structural weight is reduced, reducing the structural design of internal forces, can handle basic structures that require low, simple construction, lower cost. ★ hot-rolled steel H-beam-based, scientific and reasonable structure, plasticity and flexibility, high structural stability, suitable to withstand vibration and shock loads large architectural structure, strong resistance to natural disasters, especially for some structures more earthquake belt. According to statistics, more than occurred in the world, seven devastating earthquake disasters, mainly in H-beam steel building minimal suffer. ★ add structure effective use of space. Compared with the concrete structure, steel column sectional area is small, and thus increase the effective use of building space, depending on the form of the building, can increase the effective use of an area of ??4-6%. ★ compared with H-beam welding, can significantly cut corners to reduce raw materials, energy and labor consumption, low residual stress, good appearance and surface quality. ★ ease of machining, structural connection and installation, but also easy to remove and reuse. ★ H beam can effectively protect the environment, specifically in three areas: First, compared with concrete, can be dry construction, noise generated less dust; the second is due to reduce weight, foundation construction borrow less, little damage on land resources, in addition to a significant reduction in the amount of concrete, reducing the amount of stone mountains dig beneficial ecological environment protection; Third, after the expiration of the life of the building structure after structure demolition, a small amount of solid waste generated, recycling scrap value high. ★ high hot-rolled H-beam steel industrial production degree based, easy to manufacture, intensive production, high precision, easy to install, easy to guarantee the quality, can be built a real house production factories, bridges production factories, industrial plants production plant and so on. Development of steel, and led to the creation of hundreds of new industries. ★ construction speed, small footprint, and is suitable for all-weather construction, little affected by weather conditions. Construction speed hot-rolled H-beam steel production is about 2-3 times the speed of construction of concrete structures, capital turnover rate doubled, lower financial costs, thereby saving investment. In China's "tallest building" Shanghai Pudong "Jin Mao Tower" for example, the structure of the main body of up to nearly 400 m of just less than six months to complete the structure of the cap, but it takes two years Ganghunjiegou period.
