Specifications Introduction
Expertly crafted from exceptional high-carbon steel plates, our prestressed steel wire undergoes a refined and sophisticated manufacturing process involving state-of-the-art techniques such as acid washing, cold drawing, and phosphating. This adaptable product is offered in two principal types based on production methods: the robust cold-drawing steel wire and the stress-relieving steel wire. Tailored for diverse applications, it boasts three distinctive surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is the ideal choice for significantly enhancing the durability and strength of prestressed concrete structures, ensuring unparalleled performance.
Raw Material Requirements
Our elite prestressed concrete wire is founded on the outstanding quality of carbon steel wire rods like SWRH77B or SWRH82B. To achieve and maintain the best standards, these rods must meet a rigorous set of criteria. This includes exacting size, shape, and weight tolerances, superior chemical composition, advanced smelting methods, optimal delivery conditions, exceptional mechanical properties, reduced decarbonization, and an impeccable surface finish. All special requirements are meticulously evaluated and integrated to ensure top-tier performance and reliability.
Through the application of cutting-edge Sterem technology, our cooling process assures an extraordinary Sotenization rate that surpasses 85%. This guarantees that the coils produced fulfill the stringent specifications necessary for prestressed concrete steel wire and strands, delivering consistency and premium quality that is unmatched in the industry.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, according toASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, GOST 7348-81,TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, ABNT NBR 7482:2008,etc.
Applications for the Reinforcement of Concrete Constructions
Our meticulously engineered steel wire for prestressed concrete excels across a vast spectrum of applications. It plays a critical role in constructing single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its adaptability extends to modern high-rise buildings, underground structures, high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Perfectly suited for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it also meets the needs of projects that require extraordinary loads, shapes, and functionalities in structural engineering.
