Specifications Introduction
Crafted from top-notch high-carbon steel plates, our Premium Helical PC Wire is a testament to engineering excellence. Utilizing state-of-the-art processes such as precision acid washing, cutting-edge cold drawing, and sophisticated phosphating, this versatile wire is available in two distinct styles: the durable cold-drawing steel wire and the stress-relieving steel wire. Designed to cater to a multitude of applications, it offers three distinct surface finishes: plain for effortless integration, indented for superior bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant stands out as an unparalleled choice for augmenting the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our elite prestressed concrete wire starts with the distinguished quality of carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods are selected to adhere to stringent standards, ensuring precise dimensional accuracy, perfect shape, and exact weight tolerances. They feature top-tier chemical composition, refined smelting techniques, and ideal delivery conditions. The rods undergo rigorous examination of their exceptional mechanical properties, minimal decarbonization, and impeccable surface quality to guarantee they meet special criteria for unparalleled performance and reliability.
Our advanced cooling process, led by groundbreaking Sterem technology, achieves an impressive Sotenization rate exceeding 85%. This precision ensures our coils consistently meet the stringent demands 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
Our steel wire for prestressed concrete is expertly designed to excel across a vast range of applications. It plays crucial roles in constructing single and multi-story buildings, highway and railway bridges, durable sleepers, electric poles, high-pressure water pipes, capacious storage tanks, and resilient water towers. Its adaptability extends to contemporary high-rise structures, subterranean facilities, expansive hydraulic projects, intricate maritime constructions, and cutting-edge airport facilities, including runways and terminals. Crafted for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, it is perfect for projects necessitating extraordinary loads, distinctive shapes, and specialized functionalities in structural engineering.
