Specifications Introduction
Our Reliable Helical PC Wire is expertly crafted from top-tier high-carbon steel plates. This prestressed steel wire undergoes a sophisticated series of processes, including acid washing, cold drawing, and phosphating, to ensure unmatched quality. Offered in two distinctive production styles—the robust cold-drawing steel wire and the stress-relieving steel wire—this product is perfect for versatile applications. It is available in three unique surface finishes: plain, indented, and spiral ribbed. The cold drawing wire stands as a prime solution for significantly boosting the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our high-performance prestressed concrete is contingent upon the remarkable quality of carbon steel wire rods like SWRH77B or SWRH82B. To uphold superior standards, these rods must meet rigorous specifications, including precise tolerances in size, shape, and weight, an exceptional chemical composition, advanced smelting techniques, optimal delivery conditions, outstanding mechanical properties, minimal decarbonization, and pristine surface quality. Special requirements are thoroughly examined to guarantee unmatched performance and reliability.
Our advanced cooling process, powered by state-of-the-art Sterem technology, assures an impressive Sotenization rate exceeding 85%. This guarantees that the coils produced meet the stringent requirements for prestressed concrete steel wire and strands, delivering unmatched consistency and 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 engineered to excel across a vast spectrum of applications. It plays a vital role in the construction of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. This product's versatility extends to modern high-rise buildings, underground structures, high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. It is ideal for industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects requiring extraordinary loads, shapes, and functionalities in structural engineering.
