Specifications Introduction
Crafted from the finest high-carbon steel plates, our Premium Helical PC Wire is a masterpiece of engineering, created through state-of-the-art processes such as precision acid washing, advanced cold drawing, and sophisticated phosphating. This versatile product comes in two distinct varieties based on production technology: the resilient cold-drawing steel wire and the stress-relieving steel wire. Perfect for a range of applications, it offers three unique surface finishes: plain for seamless integration, indented for enhanced bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant stands out as an unparalleled choice for increasing the durability and robustness of prestressed concrete structures.
Raw Material Requirements
Our superior prestressed concrete wire is crafted from high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These rods are chosen with stringent standards in mind, 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' outstanding mechanical properties, minimal decarbonization, and flawless surface quality are rigorously checked to guarantee they meet specialized requirements for exceptional performance and reliability.
Our groundbreaking cooling process, powered by cutting-edge Sterem technology, achieves an impressive Sotenization rate of over 85%. This precise method ensures our coils consistently meet the rigorous demands of prestressed concrete steel wire and strands, providing remarkable consistency and superior quality.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, followingASTM 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 engineered for exceptional performance across various applications. It's pivotal in constructing single and multi-story buildings, highway and railway bridges, robust sleepers, electric poles, high-pressure water pipes, capacious storage tanks, and sturdy water towers. Its versatility encompasses modern high-rise structures, subterranean constructions, expansive hydraulic projects, intricate marine constructions, and state-of-the-art airport facilities, including runways and terminals. Tailored for industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, it is ideal for projects requiring extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
