hot rolled steel coils and plates Applicable to some multi-seismic zones

Hot-rolled steel has the following five characteristics:

1. Steel structure with hot-rolled steel, its structure is scientific and reasonable, good plasticity and flexibility, high structural stability, suitable for vibration and shock load large building structure, strong resistance to natural disasters, especially for some Multi - seismic building structure. According to statistics, in the world occurred more than 7 devastating earthquake disaster, steel-based steel structure damage the least.

2. 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%.

3. High structural strength. Compared with the same word, cross-section modulus, in the same load conditions, can save 10-15% of metal.

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

5. Structure of 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.

Hot rolled coil and cold rolled coil of the comprehensive comparison:

1, hot plate low hardness, easy processing, good ductility.

2, cold-rolled plate hardness, processing is relatively difficult, but not easy to deformation, high strength.

3, hot-rolled plate strength is relatively low, the surface quality is almost (with oxidation, low finish), but the plastic is good, generally for the plate, cold-rolled plate: high strength, high hardness, high surface finish, generally thin, Stamping plate.

4, hot-rolled steel, mechanical properties far less than cold processing, also inferior to forging processing, but with good toughness and ductility.

5, cold-rolled steel plate due to a certain degree of work hardening, low toughness, but can achieve a better yield ratio, used to cold bending spring and other parts, and because the yield point closer to the tensile strength, so the use of the process Danger is not predictable and prone to accidents when the load exceeds the allowable load.
