Specifications Introduction
Crafted with precision and care, our Premium Helical PC Wire is a testament to cutting-edge engineering. Utilizing superior high-carbon steel plates, this wire undergoes a meticulous transformation through state-of-the-art processes. These include precision acid washing, advanced cold drawing, and sophisticated phosphating, resulting in unparalleled quality. Available in two distinguished varieties based on production technology: resilient cold-drawing steel wire and the stress-relieving steel wire, this product adapts effortlessly to diverse applications. With three unique surface finishes—plain for seamless integration, indented for superior bonding, and spiral ribbed for optimal frictional engagement—our cold-drawing variant is the ultimate choice for enhancing the durability and robustness of prestressed concrete structures.
Raw Material Requirements
Building on a foundation of excellence, our premium prestressed concrete wire originates from the highest quality carbon steel wire rods such as SWRH77B or SWRH82B. These materials are chosen for their ability to meet the most stringent standards, ensuring precise size, perfect shape, and exact weight tolerances. They feature a high-grade chemical composition, refined smelting techniques, and ideal delivery conditions. The rods boast exceptional mechanical properties, minimal decarbonization, and flawless surface quality, each scrutinized to meet exacting specifications for unrivaled performance and reliability.
Our innovative cooling process harnesses pioneering Sterem technology, achieving an impressive Sotenization rate exceeding 85%. This precision ensures our coils consistently satisfy the demanding requirements of prestressed concrete steel wire and strands, delivering unmatched consistency and superior 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
Engineered for excellence, our steel wire for prestressed concrete is designed to deliver outstanding performance across a multitude of applications. It is indispensable 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 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 that demand 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.
