Prestressed Steel Strand
Prestressed steel strands are made by twisting multiple high-strength carbon steel wires around a central wire. After undergoing stress-relieving heat treatment (stabilization treatment), they possess the characteristics of high strength, low relaxation, and high elongation.The prestressed steel strands of Aosen Metal Products include steel strands and unbonded steel strands. The company uses its own produced SWRH82B raw materials. This ensures quality control from the source and the strength is stable and reliable.The raw materials undergo acid washing treatment to ensure no rust on the surface.
Common Specifications
Structure: 1*7 , 1*19
Common diameter: 12.7mm , 15.24mm , 15.7mm
Tensile strength: 1860MPa , 1960MPa
The product is produced through advanced intelligent processes such as precise drawing, twisting, heat treatment, and tensioning, and it possesses high tensile strength, low relaxation, and corrosion resistance properties.
Core function: Before the concrete components are subjected to force, a compressive stress is applied to the concrete in advance to counteract the tensile stress caused by external loads, significantly enhancing the structural's load-bearing capacity and seismic resistance, and prolonging its service life.
Standards:GB/T 5224 ; ASTM A416; BS 5896; EN 10138; KS D 7002; JIS G 3536; GOST R 53772-2010
We have our own laboratory, ensuring that all performance indicators of the products meet the requirements of our customers before they are manufactured.
Application：bridge engineering, high-rise buildings/large-span buildings, rail transit, water conservancy/electric power projects, coal mines, nuclear power plants, etc.
