Specifications Introduction
Crafted with precision and excellence, our prestressed steel wire is a masterpiece of engineering, derived from the finest high-carbon steel plates. Through a sophisticated process of acid washing, cold drawing, or stable treatment post-phosphating, this product attains unmatched quality and strength. Categorized into cold-drawing steel wire and stress-eliminating steel wire based on its production techniques, it also offers versatility through its surface options: plain, indented, and spiral rib. The cold drawing wire is directly implemented in prestressed concrete post cold drawing, ensuring optimal performance.
Raw Material Requirements
The foundation of our superior prestressed concrete lies in the use of premium high-carbon steel wire rods such as SWRH77B or SWRH82B. These rods are meticulously chosen to meet stringent criteria regarding size, shape, weight, and permissible deviations. Additionally, factors like grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements are rigorously controlled to ensure impeccable quality.
Our cooling process employs the advanced Sterem technology, allowing us to surpass an impressive Sotenization rate of 85%. Typically, coils produced via our standard processes fulfill the exacting needs for prestressed concrete steel wire and steel strand, showcasing our commitment to quality and precision in every coil.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014, ensuring consistent excellence and reliability.Prestressed concretesteel wire, adhering tothe highest international standards such as ASTM A421-16, ASTM A881/A881M-2005, BS5896-2012, EN10138-2:2009, and GOST 7348-81,TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934-2, ABNT NBR 7482:2008,and more.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is the cornerstone of modern construction, enhancing the durability and strength of single and multi-story houses, bridges, sleepers, electric poles, and pressure water pipes. Its applications extend to storage tanks, water towers, high-rise buildings, and even beyond, to underground and marine structures, airport facilities, and nuclear power plants. This versatile material supports super-tall, super-span, super-volume, super-large area, and overweight loads, proving essential in various engineering marvels.
