Specifications Introduction
Crafted from the finest high-carbon steel plates, our prestressed steel wire exemplifies precision and excellence. It undergoes a sophisticated production journey, embracing advanced techniques like acid washing, cold drawing, and phosphating. The result? A versatile product offered in two distinguished varieties: the robust cold-drawing steel wire and the stress-relieving steel wire, each designed for peak performance. Tailored for diverse applications, this exceptional wire is available in three distinctive surface finishes: plain, indented, and spiral ribbed. The cold drawing wire emerges as the ultimate solution for reinforcing the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our top-tier prestressed concrete owes its integrity to the outstanding quality of carbon steel wire rods, specifically SWRH77B or SWRH82B. Adherence to strict criteria ensures excellence: precise size, shape, and weight tolerances, superior chemical composition, refined smelting processes, ideal delivery conditions, exceptional mechanical properties, minimal decarbonization, and immaculate surface quality. Special requirements are diligently met, promising unparalleled performance and unwavering reliability for every application.
Our cooling process, driven by the revolutionary Sterem technology, showcases a remarkable Sotenization rate surpassing 85%. This groundbreaking approach guarantees that the coils we produce rise to meet—and exceed—the rigorous standards demanded by prestressed concrete steel wire and strands, offering unmatched consistency and quality.
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 steel wire for prestressed concrete is meticulously engineered to thrive across a wide spectrum of applications. It plays a crucial role in the development of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its versatility extends to modern high-rise structures, underground constructions, high-rise complexes, hydraulic endeavors, maritime projects, and airport infrastructures, including runways and terminals. Perfectly suited for industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects necessitating exceptional load-bearing capacities, unique shapes, and innovative functionalities in structural engineering.
