Extrusion Profiles According to different uses

Hot-rolled H-shaped steel according to different purposes reasonable allocation of cross-sectional size aspect ratio, with excellent mechanical properties and superior performance.

Design style is flexible and rich. In the case of high beam height, the steel structure of the open space than the concrete structure of the large 50%, so that the building layout more flexible.

Structure light weight. Compared with the concrete structure, the weight of the structure is reduced, the structural weight is reduced, the internal force of the structural design is reduced, the construction requirement of the building structure can be reduced, the construction is simple and the cost is reduced.

It is a kind of steel structure with hot-rolled H-beam, which is scientific and reasonable in structure, good in plasticity and flexibility, high in structural stability, suitable for building structures with high vibration and shock load, strong resistance to natural disasters, especially for some The building structure of the earthquake belt. According to statistics, in the world occurred more than 7 devastating earthquake disaster, the H-beam steel structure-based damage to the smallest.

Increase the effective use of the structure area. Compared with the concrete structure, the steel structure column cross-sectional area is small, which can increase the effective use of the building area, depending on the different forms of construction, can increase the effective use of the area of 4-6%.

Compared with the welding H-beam, can significantly reduce the cost of raw materials, reduce raw materials, energy and labor consumption, low residual stress, appearance and surface quality.

Easy to machine, structural connection and installation, but also easy to remove and reuse.

The use of H-beam can effectively protect the environment, the specific performance in three aspects: First, compared with concrete, dry construction can be used to produce less noise, less dust; Second, due to weight loss, the basic construction of less soil The destruction of land resources is small, in addition to a substantial reduction in the amount of concrete to reduce the amount of excavated rock, is conducive to the protection of the ecological environment; Third, the construction life of the expiration of the structure, the demolition of the structure, resulting in a small amount of solid waste, The

It is easy to ensure that the steel structure of hot-rolled H-beam steel can be made of industrial production, intensive production, high precision, easy installation and quality. It can build real factory production plant, bridge production factory, industrial factory production factory, etc. The The development of steel structure, to create and promote the development of hundreds of new industries.

Project construction speed, small footprint, and suitable for all-weather construction, affected by climate conditions. The construction speed of steel structure made of hot-rolled H-beam is about 2-3 times of the construction speed of concrete structure, the cash flow rate is doubled and the financial cost is reduced, thus saving investment. In the case of China's "first high-rise building" Shanghai Pudong's "Golden Trade Building", the structure of the main body up to nearly 400 m of the main body of the structure only less than six months to complete the structure of the cap, and steel structure requires two years.
