Product Description

15.20 low - relaxation Prestressed Steel strand is a kind of steel strand widely used in prestressed concrete structures. It is usually made of seven high - strength steel wires twisted together, with a nominal diameter of 15.20mm11. The steel strand has the characteristics of high strength and low relaxation. The tensile strength level can reach 1860MPa or even higher, and the relaxation rate after 1000h is only 1.0% - 2.5%. These properties make it able to maintain a high - level prestress in the structure for a long time, thereby improving the bearing capacity and durability of the structure. It is produced in accordance with relevant standards such as GB/T 5224 - 2014 and ASTM A416/A416M - 24. In the construction of prestressed concrete projects, this kind of steel strand is an important material to ensure the quality and performance of the project.

Bridge projects: In the construction of large - span railway and highway bridges, 15.20 low - relaxation prestressed steel strands are widely used15. For example, in the (64 + 100 + 64) m cantilever - cast prestressed curved box - girder bridge, the steel strands are used to provide the necessary prestress for the box - girder structure, which can effectively resist the self - weight, load and dynamic load of the bridge, and improve the bearing capacity and stability of the bridge8.
Building projects: In high - rise buildings and large - span public buildings such as sports stadiums, 15.20 low - relaxation prestressed steel strands are also important materials15. They can be used in the floors and beams of buildings to reduce the deformation and cracking of the structure, and improve the safety and service life of the building. For example, some large - span industrial plants use this kind of steel strand to enhance the bearing capacity of the roof and columns, so as to meet the use requirements of the plant.
Foundation pit support projects: In the construction of foundation pits of high - rise buildings and underground garages, 15.20 low - relaxation prestressed steel strands are often used for anchoring and support14. By applying prestress to the steel strands, the stability of the foundation pit slope can be enhanced, and the deformation and displacement of the foundation pit can be effectively controlled, so as to ensure the safety of the surrounding environment and buildings during the construction process.
