Specifications Introduction
Crafted from superior high-carbon steel plates, our Premium Helical PC Wire is a testament to engineering excellence. With state-of-the-art processes such as precision acid washing, advanced cold drawing, and sophisticated phosphating, this wire is available in two varieties based on production technology: cold-drawing steel wire, known for its durability, and stress-relieving steel wire, renowned for its enhanced performance. Its versatility shines through with three unique surface finishes: plain for seamless integration, indented for superior bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant, in particular, is unparalleled in enhancing the durability and robustness of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete wire begins with the highest quality carbon steel wire rods, like SWRH77B or SWRH82B, chosen to meet stringent standards. These rods ensure precise size, accurate shape, and exact weight tolerances. They are characterized by a high-grade chemical composition, refined smelting techniques, and optimal delivery conditions. Scrutinized for exceptional mechanical properties, minimal decarbonization, and impeccable surface quality, the rods fulfill special requirements, delivering unparalleled performance and reliability.
Our innovative cooling process, driven by cutting-edge Sterem technology, achieves an impressive Sotenization rate exceeding 85%. This precision ensures our coils consistently meet the rigorous demands of prestressed concrete steel wire and strands, offering remarkable 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 meticulously engineered for exceptional performance across a multitude of applications. It is pivotal in constructing single and multi-story buildings, highway and railway bridges, durable sleepers, electric poles, high-pressure water pipes, spacious storage tanks, and robust water towers. Its exceptional versatility extends to high-rise buildings, subterranean structures, vast hydraulic projects, intricate maritime constructions, and cutting-edge 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 that require extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
