Specifications Introduction
Engineered with meticulous attention to detail, our Premium Helical PC Wire is crafted from high-carbon steel plates, ensuring top-tier quality. This exceptional product undergoes cutting-edge processes such as precision acid washing, advanced cold drawing, and sophisticated phosphating to guarantee superior performance. Available in two varieties—resilient cold-drawing steel wire and stress-relieving steel wire—it caters to diverse needs with three distinctive surface finishes: plain for seamless applications, indented for enhanced bonding, and spiral ribbed for optimal frictional engagement. The cold-drawn variant stands unrivaled in enhancing the durability and robustness of prestressed concrete structures, making it the ultimate choice for construction professionals.
Raw Material Requirements
Our esteemed prestressed concrete wire is founded on the exceptional quality of carbon steel wire rods such as SWRH77B or SWRH82B. These rods are meticulously chosen to satisfy stringent criteria, ensuring precise size, immaculate shape, and exact weight tolerances. They possess a high-grade chemical composition, refined smelting techniques, and optimal delivery conditions. With exceptional mechanical properties, minimal decarbonization, and impeccable surface quality, these rods are rigorously evaluated to meet specialized requirements, ensuring unparalleled performance and reliability.
Harnessing the power of our pioneering cooling process with advanced Sterem technology, we achieve an impressive Sotenization rate exceeding 85%. This precision ensures our coils consistently fulfill the exacting requirements of prestressed concrete steel wire and strands, offering remarkable consistency, superior quality, and dependable performance.
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 designed to deliver exceptional performance across a multitude of applications. It plays a pivotal role in constructing single and multi-story buildings, highway and railway bridges, durable sleepers, electric poles, high-pressure water pipes, capacious storage tanks, and robust water towers. Its versatility is further extended to modern high-rise edifices, subterranean structures, expansive hydraulic projects, intricate maritime constructions, and state-of-the-art airport facilities, including runways and terminals. Tailored for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it is the ideal choice for projects requiring extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
