Specifications Introduction
Crafted with precision, our Premium Helical PC Wire is produced using superior high-carbon steel plates. These wires are expertly crafted through a series of state-of-the-art processes, including meticulous acid washing, innovative cold drawing, and advanced phosphating techniques. Designed for versatility, the wire is offered in two distinct forms: the durable cold-drawing steel wire and the stress-relieving steel wire. With three unique surface finishes—plain for effortless integration, indented for superior bonding, and spiral ribbed for exceptional frictional engagement—this product is perfect for reinforcing the strength and resilience of prestressed concrete structures.
Raw Material Requirements
Our exquisite prestressed concrete wire is based on the exceptional quality of carbon steel wire rods such as SWRH77B or SWRH82B. Each rod is selected meticulously to adhere to stringent standards, ensuring precise sizing, flawless shaping, and accurate weight tolerances. These rods feature high-grade chemical compositions, refined smelting techniques, and optimal delivery conditions. With superior mechanical properties, minimal decarbonization, and impeccable surface quality, they are inspected rigorously to exceed special requirements for unmatched performance and reliability.
Utilizing our groundbreaking cooling process, enhanced by the innovative Sterem technology, we achieve an outstanding Sotenization rate exceeding 85%. This precision guarantees that our coils consistently meet the demanding requirements of prestressed concrete steel wire and strands, delivering unparalleled consistency and top-tier 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 expertly engineered steel wire for prestressed concrete is crafted to deliver outstanding performance across a plethora of applications. It plays crucial roles in the construction of single and multi-story buildings, highway and railway bridges, resilient sleepers, electric poles, high-pressure water pipes, large storage tanks, and robust water towers. Its remarkable versatility extends to modern high-rise buildings, underground structures, expansive hydraulic projects, intricate maritime constructions, and advanced airport facilities, including runways and terminals. Ideal for industries demanding super-tall, super-span, super-volume, and ultra-large-area constructions, it is perfectly suited for projects requiring extraordinary loads, unique configurations, and specialized functionalities in structural engineering.
