Specifications Introduction
Meticulously crafted from superior high-carbon steel plates, our Premium Helical PC Wire exemplifies excellence in engineering, utilizing state-of-the-art processes. From precision acid washing to advanced cold drawing and sophisticated phosphating, every step is tailored to perfection. Available in two distinct production varieties—the resilient cold-drawing steel wire and the stress-relieving steel wire—it accommodates diverse applications with three unique surface finishes: plain for seamless integration, indented for enhanced bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant is unparalleled in bolstering the durability and robustness of prestressed concrete structures, ensuring enduring performance.
Raw Material Requirements
Our premium prestressed concrete wire is founded on the exceptional quality of carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods are meticulously chosen to satisfy rigorous criteria, ensuring precise sizing, perfect shaping, and exact weight tolerances. They boast a high-grade chemical composition, refined smelting techniques, and ideal delivery conditions, coupled with exceptional mechanical properties, minimal decarbonization, and impeccable surface quality. Each rod undergoes meticulous scrutiny to ensure they meet special requirements for performance and reliability that are simply unparalleled.
Our innovative cooling process, spearheaded by cutting-edge Sterem technology, achieves a remarkable Sotenization rate exceeding 85%. This precision guarantees our coils meet the demanding standards of prestressed concrete steel wire and strands, delivering exceptional consistency and superior quality that define excellence.
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 expertly engineered to deliver exceptional performance across a multitude of applications. It plays a pivotal role in the construction of 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 remarkable versatility extends to modern high-rise edifices, subterranean structures, expansive hydraulic projects, intricate maritime constructions, and state-of-the-art airport facilities, including runways and terminals. Ideal for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it is perfect for projects requiring extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
