Using SWRH82B 1*7 structure Φ15.24mm prestressed steel strand is ordinary bonded steel strand (can be made unbonded), with material and strength grades including 1860MPa, 1960MPa, 2160MPa.
Description
We are a professional manufacturer of pre-stressed steel strand, not a trader.
Through the scientific selection of production processes, high-quality configuration of core equipment, and refined parameter control throughout the entire production process, we can achieve precise control over every link from raw materials to finished products. This endows our steel strand with distinct advantages in core dimensions such as mechanical properties, structural stability, and durability and damage resistance, fully meeting the requirements for high load, high reliability and long-cycle service in engineering applications.
Structure ：1*7，1*19
Diameter ：9.53mm，12.7mm，15.2mm，15.7mm，17.8mm，18.9mm，21.6mm，28.6mm
Tensile Strength：1770MPa，1860MPa，1960MPa，2160MPa
Product Customization: Raw materials, tensile strength, weight, length, packaging method (e.g., with fumigated wooden strips added), and other customer requirements.
We can supply unbonded steel strand (HDPE-coated steel strand) per your specific requirements.
We adhere to the following international standards in the supply of industrial pre-stressed steel strand.
GB/T5224；ASTM A416；BS 5896；EN 10138；JIS G3536；GOST R 53772-2010
We also have a complete set of inspection equipment, conduct inspections on each batch of products, and all our products are delivered from the factory with accompanying inspection reports.
